AB  - In the rapid development of microelectronics, energy, and automotive sectors, as well as Radio-Frequency (RF) telecommunications, the pollution from Electromagnetic Waves (EWs) is perpetual. Electromagnetic interferences (EMI) cause destruction and disruptive impacts on equipment and systems, affecting both ordinary use and specialized, expensive instruments utilized in research facilities. The EMI may lead to unreliable signals and radio frequency (RF) interference. Materials capable of neutralizing EMI effects are essential to minimize deterioration caused by undesired currents and voltages, instrument blockage, incorrect results, and to minimize measuring time. The GrInShield project aims to solve the aforesaid issues by creating innovative shieldinqg graphene-based nanomaterials that are resistant against EMI.

AB  - The ongoing progress in communications, broadcasting systems, and the electronic industry results in increased exposure to electromagnetic interference (EMI). The proliferation of electromagnetic waves pollution is attributed to the extensive use of electronic devices like mobile phones, Wi-Fi, and microwave ovens in everyday activities [1, 2]. The risk of EMI is especially highlighted for individuals with implanted active medical devices or profesionals working in close contact to this type of irradiation. EMI shielding materials with 30 dB shielding efficiency are deemed appropriate for commercial applications based on references. Therefore, there is a strong need for lightweight, elastic, stretchy, transparent, robust, and highly efficient shielding materials that are appropriate for textile manufacturing and equipment covering. Presented work investigated composite materials made of graphene oxides (GO) [3] and silver nanowires (AgNWs) and their effectivenes as EMI shielding materials. Composites were generated from GO with sheet sizes ranging from 150 to 2000 nm and flake thicknesses between 2 and 5 nm. The average thickness of the free-standing films was approximately 14.8 μm. The ratio of these nanomaterials was analysed to adjust the shielding effectiveness throughout a wide microwave frequency range up to 18 GHz. A shielding effectiveness of around 6.5 dB was recorded for the r-GO free-standing film.

AB  - Carbon quantum dots (CQDs) have exceptional physical-chemical properties that make them suitable for a wide range of uses, such as the photocatalytic removal of organic contaminants from water. Here, we provide a one-step, ecologically friendly, and economical method for creating iron/nitrogen co-doped (Fe/N-CQD) and nitrogen-doped (N-CQD) quantum dot nanomaterials. The characteristics of the developed nanomaterials were investigated with regard to how surface chemistry impacts their capacity for adsorption and photoactivity in a case study of a specific water pollutant reduction. The influence of the two irradiation sources-operating in the UV and visible ranges-on the photoactivity of materials was highlighted. Finally, their eco-friendliness was examined on four different human tumor cell lines.

AB  - Emerging issues triggered by rapid industrialization and technological development demand productive green solutions for water and ecosystem preservation. Zero-dimensional (0D) carbon nanomaterials (CNMs) with ultra-small size, outstanding characteristics, and antibacterial effect have shown tremendous potential as photocatalysts in water purification treatment as adsorbents, ion detectors, and/or in remediation of hazardous pollutants. This chapter aims to highlight a few 0D CNMs with unique features acquired for selective photocatalytic processes. An emphasis would be given to the impact of the physical and chemical properties of different CNMs on the removal efficiency of organic pollutants from water media. Furthermore, under a broad spectrum of light, the photoactivity of selected CNMs in the form of nanoparticles or membrane/composite systems will be prioritized. Finally, the readership will be introduced to the benefits and limitations of 0D carbon–based nanomaterials’ potential application on an industrial scale.

AB  - This study aimed to compare the effectiveness of adsorption and photocatalysis techniques at removing the herbicide clomazone (CLO) and the antidepressant known as amitriptyline (AMI) from water. This study employed kinetic models to analyze the removal processes and assess the potential toxicity of the treated water. The structure and morphology of the prepared multi-walled carbon nanotubes were characterized as adsorbents by transmission electron microscopy, X-ray diffraction, Fourier transform infrared techniques, and Raman spectroscopy. The adsorption kinetics of CLO and AMI were studied on the pristine and functionalized multi-walled carbon nanotubes. Kinetic studies were performed by modeling the obtained experimental data using three kinetic models: pseudo-first-order, pseudo-second-order, and Elovich kinetic models. On the other hand, the efficiency of CLO and AMI photodegradation was examined as a function of the type of irradiation (UV and simulated solar irradiation) and type of TiO2 photocatalyst (Aeroxide and Kronos). Under the experimental conditions employed, the reaction followed pseudo-first-order kinetics. Additionally, in order to assess the toxicity of water containing CLO, AMI, and their intermediates, toxicity assessments were conducted using human fetal lung fibroblast cells. The results obtained indicate the effectiveness of both methods and provide valuable insights into their removal mechanisms, contributing to the advancement of sustainable water treatment strategies.

AB  - The large number of deaths induced by carcinoma and infections indicates that the need for new, better, targeted therapy is higher than ever. Apart from classical treatments and medication, photodynamic therapy (PDT) is one of the possible approaches to cure these clinical conditions. This strategy offers several advantages, such as lower toxicity, selective treatment, faster recovery time, avoidance of systemic toxic effects, and others. Unfortunately, there is a small number of agents that are approved for usage in clinical PDT. Novel, efficient, biocompatible PDT agents are, thus, highly desired. One of the most promising candidates is represented by the broad family of carbon-based quantum dots, such as graphene quantum dots (GQDs), carbon quantum dots (CQDs), carbon nanodots (CNDs), and carbonized polymer dots (CPDs). In this review paper, these new smart nanomaterials are discussed as potential PDT agents, detailing their toxicity in the dark, and when they are exposed to light, as well as their effects on carcinoma and bacterial cells. The photoinduced effects of carbon-based quantum dots on bacteria and viruses are particularly interesting, since dots usually generate several highly toxic reactive oxygen species under blue light. These species are acting as bombs on pathogen cells, causing various devastating and toxic effects on those targets.

AB  - Accumulation of disposable plastic products with an estimated life-time of at least 400 years overcomes the world's capability to deal with them. Only a relatively small portion of plastics is being recycled mostly due to their chemical composition and high remanufacturing cost. Consequently, plastic waste accumulation in the environment became one of the most pressing environmental problems of the XXI century leading to the rapid increase in the plastic pollution crisis, with a characteristic example to be the Oceans “plastic” island. The possibility of plastic waste conversion into valuable materials such as graphene, a 2D nanomaterial with extraordinary properties and potential for utilization for a plethora of applications from electronics to biomedicine, could be a key technology in promoting green and sustainable alternatives. This chapter aims to underline the prospects and limitations of plastic waste conversion into graphene/graphite and graphene-based nanomaterials (Graphical Abstract). An emphasis would be given to the type of the source material, and the correlation of their chemical nature toward the quality and quantity of the obtained graphene nanomaterial. Furthermore, through a comparison of the conventional methods and precursors for graphene production to the plastic waste upcycling method, the ecological impact of used chemicals and byproducts will be discussed. Finally, the overview of the potential application of the produced graphene and graphene-based nanomaterials as well as the prospects of using waste materials for graphene production will be introduced.

AB  - Zinc phthalocyanine, synthesized under microwave irradiation proved to be an interesting photocatalyst. The degradation of Rose Bengal, as model organic dye, under visible light irradiation was used to study the adsorption/photocatalytic activity. The huge potential of the synthesized molecule for the removal of organic pollutants was demonstrated by its absorption capacity, which was far larger than that of dye degradation.

AB  - Biocatalysis utilizes enzymes and microbial cells as catalysts for a wide range of applications in biotechnology. Immobilization of biocatalysts on various materials has several advantages, including the capacity for reuse, quick reaction termination, easy biocatalyst recovery and operational stability. The present article focuses on the use of material supports for developing immobilized biocatalysts in applications related to energy, environment and chemical synthesis. The work provides a comprehensive overview of a broad class of materials, including organic, inorganic and composites, that have been shown to be prosperous candidates to support the immobilization of enzymes and microbial cells. It also highlights the properties of nanomaterial support such as large surface area and comfort compartment for immobilization. The availability of different types of materials as catalyst support provides an opportunity to understand and develop efficient biocatalytic systems. The choice of selecting a catalyst support will mostly depend on the interaction of the material with the enzyme or microbial cell.

AB  - Environmental protection and energy conversion by state-of-the-art photocatalysts emerge as imperative in pursuit for ideal, sustainable, and green oriented solutions. However, major drawbacks in broader application of one of the most promising semiconductor photocatalyst, titanium dioxide (TiO2), lie in the need for enhancing visible-light absorption and elevating the photocatalytic reactivity. Toward these directions, narrowing the material band gap and functionalization of the surface chemistry are among the most prosperous materials design approaches. As reported in earlier work, the surface structure engineering proved to be an encouraging approach to endow optical and electrical properties of the TiO2-based material. For the first time, the black powder of TiO2 with a disordered lattice and hydrogen surface doping was obtained through hydrogenation under high pressure and temperature, consequently leading to narrowing the optical band gap to 1.54eV. The presented chapter aims to reveal in-depth all the literature available information related to the black titania synthesis in addition of sharing in details its prosperous physicochemical properties. Feature information related to the photocatalytic activity of black TiO2 as well as of the most crucial features will also be provided. Finally, the chapter will conclude with the derived significant benefits of such material properties in photocatalytic treatment of organic pollutants and hydrogen production. © 2023 Elsevier Inc.

AB  - Carbon quantum dots (CQDs), are a novel class of carbon nanomaterials that exhibit outstanding physical, chemical, and optical characteristics in addition to strong light absorption. By substituting some of the carbon atoms in CQDs for heteroatoms like N, B, P, and S, it is possible to modify the surface chemistry and electronic properties of the structures, boosting their catalytic activity. Adding B dopant to CQDs changes its surface chemistry and morphology, opening up a wide range of potential uses. The presented study illustrates a quick and environmentally friendly method for producing B-CQDs through microwave-assisted method. According to TEM characterization, the generated B-CQDs had a spherical form, an average diameter of 12 nm, and were negatively charged particles with good water dispersibility and no discernible aggregation. The thorough surface chemistry characterization revealed the presence of B-O and B-C bonds, as well as oxygen-containing surface functional groups in the form of hydroxyl, carbonyl, and carboxyl groups. Additionally, using an RB organic dye as a model molecule, the sonocatalytic, photocatalytic, and synergistic effects of the two processes were investigated.

AB  - The carbon quantum dots (CQDs) as zero-dimensional carbon nanomaterials with extraordinary physicochemical properties have a broad range of applications. Some of the most intriguing is the CQD thin films for electronic devices and membrane nanofiltration. Here we present the simple and affordable microwave-assisted synthesis method for the production of the nitrogen-doped CQDs (N-CQD) and iron/nitrogen co-doped CQDs (FeN-CQD). The comprehensive study of the morphology and electrical properties of N-CQD and FeN-CQD was discussed after manufacturing obtained nanomaterials in the form of a thin film on different substrates using different deposition procedures. The morphological features of generated thin films altered dramatically when the substrate and nanomaterial properties, as well as the number of deposited layers of CQDs and the chosen deposition process, were taken into consideration.

AB  - This article investigates the morphology of polyaniline/electrochemically exfoliated graphene composites prepared by oxidative polymerization with ammonium persulfate at a constant temperature (15 °C). During the polymerization, the pH of the reaction mixture decreases, which was used to monitor the rate of the reaction. A granular morphology with the presence of large sheet-like structures is found to be predominant for the composite prepared without added acid, while rod-shaped and tubular morphology is characteristic for the composite prepared with the addition of glacial acetic acid. The nanotubular and nanorod morphology of the sample prepared with the addition of glacial acetic acid was also confirmed by the presence of prominent phenazine structural units in Raman spectra. The composite prepared with the addition of HCl has granular morphology with a small amount of rod-like structures.

AB  - The modern age science is still searching for an effective photocatalytic material for the treatment of colored discharges from different industries which cause severe environmental issues. The excellent properties of nitrogen doped carbon quantum dots (N-CQD) enable their successful application as photocatalytic material in organic dye removal triggered under light absorption. With this in mind we first present a successfully performed microwave-assisted synthesis method, a green, simple and economically affordable method for N-CQD synthesis with high nitrogen percentage incorporated in the form of pyrrolic, pyridinic/NH2 and graphitic/NH3+ groups. The pro-oxidant and antioxidant features of the synthesized N-CQD were further presented, with high removal efficiency of synthesized N-CQD towards the methylene blue (MB) organic dye, as one of the leading water pollutants with a major risk to aquatic and human life.

AB  - The herein presented ultrasound-assisted ultra-wet (US-UWet) impregnation synthetic approach was followed in order to avoid the drawbacks of the conventional wet impregnation synthesis. The goal was to homogeneously decorate the surface of the TiO2 nanoparticles with nanometric sized (< 4 nm) clusters of mixed cupric and cuprous oxides. The physicochemical features of the nanocomposite (TiO2CuOx) were determined by high-angle annular dark-field scanning transmission electron microscope (HAADF-STEM), high-resolution transmission electron microscopy (HR-TEM), energy dispersive X-ray (EDX), X-ray photoelectron spectroscopy (XPS), powder X-ray diffraction (XRD), and Diffuse reflectance (DR) spectroscopy. TiO2CuOx showed an enhanced and continuous capability to generate molecular hydrogen upon low power ultraviolet irradiation. The benchmark commercial TiO2 P25 did not reveal any H2 formation under these conditions. TiO2CuOx presented also a high efficiency for the additives-free selective partial oxidation of two well established biomass derived model platform chemicals/building blocks, 5-hydroxymethylfurfural (HMF) and benzyl alcohol (BnOH) to the value-added chemicals 2,5-diformylfuran (DFF) and benzyl aldehyde (PhCHO), respectively. The nanocomposite showed higher DFF and PhCHO yield compared to P25.

AB  - The interest in homogeneous photocatalysis arises from the high activity and selectivity advantages of controlled photochemical transformations such as synthesis of chemical/pharmaceutical products or complete degradation/mineralization of hazardous compounds. However, the major drawback of homogeneous photocatalytic reactions lies in the separation and recovery of the photocatalyst after the reaction, necessary to make the photocatalytic process eco-friendly. Immobilization of homogeneous photocatalysts on different supports is considered to be a viable method to increase the retainability and reusability of the photocatalyst simultaneously. This chapter aims to provide an in-depth information related to the immobilization of various homogeneous photocatalysts on well-known synthetic and natural polymers. Detailed information related to the potential environmental and chemical synthesis applications of immobilized homogeneous photocatalysts are also discussed. Finally, this chapter concludes with a new direction in emerging technologies for developing better supported photocatalysts. Graphical Abstract Unlabelled Image

AB  - Wastewater treatment is an emerging problem in the industrialized world. The development of new semiconducting materials with the potential to be used in photocatalysis is the focus of the scientific community. Here, we present the synthesis of N-doped carbon quantum dots (N- CQDs) using microwave radiation. N-CQDs were synthesized by irradiation of glucose solution in the presence of ammonia hydroxide as a nitrogen doping agent at low temperature (100 °C), low applied microwave power (100 and 200 W), and for a short period of time (60 s). The possible application of N-CQDs as a catalyst for photocatalytic degradation of Methylene Blue (MB) dye under blue light, green light, red light, and daylight was investigated. The highest values of MB degradation were observed for the samples exposed to red light with a maximum of 58.8 % for N-CQDs sample prepared at the reactor power of 200 W exposed to red light for 2 h.

AB  - Industries today realis high amounts of different hazards into the environment without any pre– treatment, which is why the remediation from organic pollution still represents one of the most important issues in waste water treatment. Organic dyes from textile industry are one of the extremely geno‒toxic and cyto‒toxic pollutants. Thus, finding the appropriate photocatalyst for the treatment of contaminated water under sunlight is still a challenging work from economical and green chemistry approach. Here we present a microwave assisted synthesis of nitrogen doped carbon quantum dots with high efficiency in degradation of Rose Bengal organic dye from water under visible, blue, green and red light irradiation in batch system. The effect of microwave irradiation power and time on size and photocatalytic activity of synthesized dots were also investigated.

AB  - Herein, we present microwave-assisted reductive amination of oxo derivative of deoxycholic acid with morpholine in the presence of sodium-cyanoborohydride. These chemical transformation produces a majority of the 3β-amino isomer 5 as a new compound after five minutes of irradiation. In addition, formylated bile acid have been proved as excellent starting material for the synthesis of bile acid`s N-morpholino amine. Microwave-assisted reactions of formylation in the absence of catalyst, selective deformylation, as well as further oxidation with N-bromosuccinimide gained 3-oxo derivatives of deoxycholic acid acid in high yield. Compared to the conventional protocol a remarkable reduction in overall processing time from hours to a few minutes was achieved.

abstract = "Herein, we present microwave-assisted reductive amination of oxo derivative of deoxycholic acid with morpholine in the presence of sodium-cyanoborohydride. These chemical transformation produces a majority of the 3β-amino isomer 5 as a new compound after five minutes of irradiation. In addition, formylated bile acid have been proved as excellent starting material for the synthesis of bile acid`s N-morpholino amine. Microwave-assisted reactions of formylation in the absence of catalyst, selective deformylation, as well as further oxidation with N-bromosuccinimide gained 3-oxo derivatives of deoxycholic acid acid in high yield. Compared to the conventional protocol a remarkable reduction in overall processing time from hours to a few minutes was achieved.",

AB  - Industrialization today leads to a significant increase in the environmental pollution, with number of phenols, pesticides, paints, solvents and other organic pollutants with potentially carcinogenic effect in natural resources. Investigation of some new semiconductor materials and their photocatalytic properties for removal of pollutants is a challenging work. However, limited usage of photoactive materials still requires the testing of new materials with photoactive properties. The current work introduces the swift and easy approach for synthesis of (metal–free) N–doped carbon quantum dots in water using microwave reactor. Synthesis was performed from glucose water solution by heating in microwave reactor for only 1 min, at low temperature and applied microwave power. The synthesized N–doped carbon quantum dots show remarkable photocatalytic activity for removal of toxic organic dye (Rose Bengal) under visible light irradiation. Almost 93% of the dye degradation is achieved after only 30 min of radiation. The uninspected result, that the pH of the medium has a significant effect on the performance of the synthesized material in the presence of organic dye, indicates that dots show dual behavior. In the neutral and basic conditions, they have the ability to degrade organic dye, whereas, by shifting the medium pH into acidic medium, they form a stable conjugate with Rose Bengal. © 2019 Elsevier Ltd and Techna Group S.r.l.

AB  - Graphene as a new material is in the spotlight due to its extraordinary properties and wide range of potential applications. Chemical vapour deposition, as a method for graphene synthesis from gaseous hydrocarbon sources has great promises for large-scale graphene synthesis. However, for such grow high temperatures of 800-1000 degrees C are typically required. Here we demonstrate synthesis of single-layer and bi-layer graphene thin films of approximately 10,m in size by rapid thermal annealing process at low annealing temperature such as 600 degrees C. Synthesis was performed on copper foil from graphene quantum dots and fullerenol as solid carbon sources at different concentrations. Raman spectroscopy study has shown that the number of grown graphene layers depends on the carbon source concentration. The quality of formed graphene layers withal depends on the carbon source and its concentration, whereby graphene from graphene quantum dots had better quality. (C) 2016 Elsevier Ltd.

AB  - In this paper, we present a novel method for graphene nanoribbons formation using nickel nanowires as templates. Modification of electrochemical procedure for nickel nanowires synthesis was introduced by implementing graphene quantum dots as a carbon source. Thus, nickel nanowires with graphene quantum dots were prepared. These wires were exposed to rapid thermal annealing at high temperatures (500 degrees C, 700 degrees C and 800 degrees C). During this process carbon atoms dissolve in metal and precipitate to the nickel surface forming nickel-carbon nanowires. Atomic force microscopy, scanning electron microscopy and Raman spectroscopy were characterization methods used for analysis of changes in nickel-carbon nanowires properties depending on the different annealing temperatures. After etching nickel with nitric acid, graphene nanoribbons with average diameters of 32 nm and average lengths of 4 mu m were obtained. (C) 2016 Elsevier B.V. All rights reserved.
