Carbon quantum dots are the materials of a new era with astonishing properties such as high photoluminescence, chemical tuneability and high biocompatibility. Since their discovery, carbon quantum dots have been described as nanometric high-fluorescent carbon nanoparticles, but this definition has become weaker year after year. Nowadays, the classification and the physical explanation of carbon quantum dots optical properties and their chemical structure remain matter of debate. In this review, we provide a clear discussion on these points, providing a starting point for the rationalization of their classification and a comprehensive view on the optical and chemical features of carbon quantum dots.

“…The reduction and prevention of environmental pollutants serve as indispensable measures in protecting the human health, conserving the environment, and fostering sustainable economic development. Various issues can arise from these environmental pollutants, such as reduced oxygen levels, toxicity, changes in pH levels, nutrient pollution, and contamination. − Pharmaceutical pollutants, residues of drugs, and their byproducts can enter the water through various sources, have harmful ecological and human health effects, and present challenges for water treatment. − The COVID-19 outbreak, also known as the coronavirus pandemic, has had far-reaching impacts on the environment, society, and economy worldwide. − One of the most noticeable impacts of the pandemic has been on the environment . The COVID-19 pandemic has caused a considerable escalation in the indiscriminate consumption of single-use plastics and medical waste, which has resulted in increased pollution in some areas. , Pharmaceutical pollutants are a growing environmental concern as the widespread use of COVID-19 drug treatments continues to increase globally.…”

Insights into the Adsorption Properties of Mixed Matrix Membranes (Pebax 1657-g-Chitosan-PVDF-Bovine Serum Albumin@ZIF-CO₃-1) for the Antiviral COVID-19 Treatment Drugs Remdesivir and Nirmatrelvir: An In Silico Study

The effect of the COVID-19 pandemic on the accumulation of environmental pollutants has been significant. In that way, waste management systems have faced problems, and the amount of hazardous and medical wastes has increased. As pharmaceuticals associated with the treatment of COVID-19 enter the environment, aquatic and terrestrial ecosystems have been negatively impacted, potentially disrupting natural processes and harming aquatic life. This analysis seeks to appraise the potential of mixed matrix membranes (MMMs) composed of Pebax 1657-g-chitosan-polyvinylidene fluoride (PEX-g-CHS-PVDF)-bovine serum albumin (BSA)@ZIF-CO 3 -1 as adsorbents for removing remdesivir (REMD) and nirmatrelvir (NIRM) from aqueous environments. An in silico study was conducted to explore the adsorption characteristics, physicochemical properties, and structural features of these MMMs, employing quantum mechanical (QM) calculations, molecular dynamics (MD) simulations, and Monte Carlo (MC) simulations as research methodologies. Incorporating BSA@ZIF-CO 3 -1 into the PEX-g-CHS-PVDF polymer matrix improved the physicochemical properties of MMMs by promoting the compatibility and interfacial adhesion between the two materials, facilitated by electrostatic interactions, van der Waals forces, and hydrogen bonding. Investigation of the interaction mechanism between the title pharmaceutical pollutants and the surfaces of MMMs, along with the description of their adsorption behavior, was also conducted by applying MD and MC approaches. Our observations indicate that the adsorption behavior of REMD and NIRM is influenced by molecular size, shape, and the presence of functional groups. Molecular simulation analysis demonstrated that the MMM membrane is a highly suitable adsorbent for the adsorption of REMD and NIRM drugs, with a higher affinity toward REMD adsorption. Our study emphasizes the significance of computational modeling in developing practical strategies for eliminating COVID-19 drug contaminants from wastewater. The knowledge obtained through our molecular simulations and QM calculations can assist in creating more efficient adsorption materials, resulting in a cleaner and healthier environment.

“…However, challenges remain in term of poor solar absorption with low solar-thermal conversion efficiency, massive thermal losses to surroundings, low freshwater yield, and scalable fabrication techniques which hinders the practical implacability of fabricated devices. [14,16,17] Although several photothermal materials (i.e., metallic nanoparticles, [18] semiconductors, [19,20] and carbon-based materials [21,22] ) and integrated freshwater-generating devices have been engineered [23,24] however, because of a major scaffold between the status quo and industrial applications, their practical uses are still at an infant stage. Thus, there is a surge to exploit eco-friendly photothermal materials for the development of cost-effective, excellent mechanical/chemical stability, and multiple contaminations rejecting solar steam generation to provide incredible possibilities in the realm of solar-to-thermal technologies.…”

The development of a multi‐functional solar‐driven interfacial evaporation (SDIE) system remains a significant challenge for its large‐scale applications. By taking advantage of high surface area, excellent young's moduli, anchoring/coupling capability, large absorption surface, strong absorption in the broadband solar spectrum, and efficient photothermal conversion efficiencies of 2D emerging materials (Xenes, Mxenes, etc.), hybrid SDIEs are developed to increase the use of solar energy beyond water production. This work aims to offer a systematic review of the recent advancement in 2D emerging materials except for graphene and their significant role in hybrid SDIEs to stimulate both fundamental and applied research on utilizing the underutilized auxiliary energy sources for future integrated water, energy, and environmental systems. For this purpose, first, the most recent progress in 2D photothermal materials is discussed, mainly including emerging Xenes, MXenes, and TMDs‐inspired hybrid SDIEs. Second, structural optimization strategies and modulation of the intrinsic photothermal performances of 2D emerging materials are highlighted. Third, the cutting‐edge conceptual designs developed in many hybrid applications such as thermoelectricity, salt recovery, and hydrogen production are broadly presented. Lastly, the current challenges and perspectives of 2D emerging materials and their hybrid evaporation structures are also mentioned.
