As a philosophical support, green chemistry (GC) becomes at present well-combined into the scientific system to assist scientists and engineers consider how to decrease or remove waste and avert the employment and formation of hazardous substances in the design phase of chemicals. Such design attempts in turn affect the full life-cycle of the chemical, from getting the starting materials until the end-use product is recycled or disposed of. There is a considerable advance noted in such direction during the last three decades, this review focuses on GC research. As a comparatively fresh technique, revision in process intensification (PI) is fast and investigation could rapidly lead to outstanding outcomes. However, numerous features of PI could take more time to be fact. Much of the study stays in academic and industrial laboratories, even if large-scale implementations of micro-reactors are actuality. Fields of PI enterprise that have progressed quickly are the expansion of carbon capture techniques, an increasing interest in GC, and the beginning of momentous study into connecting solar energy to intensified methods like chemical reactions. Electric fields (e.g., microwaves and ultrasound) are observed in larger usages, and the application of electrokinetic forces at the micro- and nanoscale persist to fascinate. Huge investigations are working for the sake of ideas like the perfect reactor. PI remains a motif leading to attain a sustainable society. This work may be an orientation in the investigation of product development and design, production and application, in a constructive and stimulating way.

“…LFMs have created a new category of water filtration technologies, as they are a biodegradable material that may be fabricated into virtually any shape from μm to mm dimensions, 16 and be structurally and chemically modified to impregnate anti-fouling 17,18 and/or diffusion properties. 4,19 A multitude of subsequent studies can be developed upon this proof of concept, e.g., permeability modifications, 11 functional modifications through incorporation of other molecules, [20][21][22] and optimization of the engineering design and operation conditions. 23 To integrate environmental considerations into future technology development (i.e., Ecodesign), 24,25 herein we conduct a preliminary life cycle assessment of LFMs as a drinking water filtration technology.…”

Living Filtration Membranes (LFMs) are a water filtration technology that was recently developed in the lab (Technology Readiness Level 4). LFMs have shown filtration performance comparable with that of ultrafiltration, far better fouling resistance than conventional polymer membranes, and good healing capabilities. These properties give LFMs promise to address two significant issues in conventional membrane filtrationfouling and membrane damage. To integrate environmental considerations into future technology development (i.e., Ecodesign), this study assesses the life cycle environmental performance of LFMs treating drinking water under likely design and operation conditions. It also quantitatively ranks the engineering design and operation factors governing the further optimization of LFMs' environmental performance using a global sensitivity analysis. The results suggest that LFMs' superior fouling resistance will reduce the life cycle environmental impacts of ultrafiltration by 25% compared to a conventional polymer membrane in most impact categories (e.g., Acidification, Global Warming Potential and Carcinogenics). The only exception is the eutrophication impacts, where the need for growth medium and membrane regeneration offsets the benefits of LFMs' fouling resistance. Permeability is the most important factor that should be prioritized in future R&D to further improve LFMs' life cycle environmental performance. A 1% improvement in the permeability will lead to a ~0.7% improvement in LFMs' environmental performance in all the impact categories, whereas the same change in the other parameters investigated (e.g. LFM lifespan and regeneration frequency) typically only leads to a <0.2% improvement.

“…Recently, it has been found that it is possible to encode light-induced, membrane-potential-based memory-patterns within bacteria in intimate contact as a biofilm [ 11 ]. Besides the noxious impact on food, water quality and health care industry, biofilms can serve as a useful and sustainable alternative to provide a low-cost source of power and clean sustainable energy or even act beneficially during cost-effective and sustainable water treatment procedures for some types of filters [ 12 ]. Nevertheless, the spread of contagious microorganisms and robust biofilm development is seen as a threat for human health and compromises the quality and performance of various man-made products.…”

Ag-Based Synergistic Antimicrobial Composites. A Critical Review

et al. 2021

View full text Add to dashboard Cite

The emerging problem of the antibiotic resistance development and the consequences that the health, food and other sectors face stimulate researchers to find safe and effective alternative methods to fight antimicrobial resistance (AMR) and biofilm formation. One of the most promising and efficient groups of materials known for robust antimicrobial performance is noble metal nanoparticles. Notably, silver nanoparticles (AgNPs) have been already widely investigated and applied as antimicrobial agents. However, it has been proposed to create synergistic composites, because pathogens can find their way to develop resistance against metal nanophases; therefore, it could be important to strengthen and secure their antipathogen potency. These complex materials are comprised of individual components with intrinsic antimicrobial action against a wide range of pathogens. One part consists of inorganic AgNPs, and the other, of active organic molecules with pronounced germicidal effects: both phases complement each other, and the effect might just be the sum of the individual effects, or it can be reinforced by the simultaneous application. Many organic molecules have been proposed as potential candidates and successfully united with inorganic counterparts: polysaccharides, with chitosan being the most used component; phenols and organic acids; and peptides and other agents of animal and synthetic origin. In this review, we overview the available literature and critically discuss the findings, including the mechanisms of action, efficacy and application of the silver-based synergistic antimicrobial composites. Hence, we provide a structured summary of the current state of the research direction and give an opinion on perspectives on the development of hybrid Ag-based nanoantimicrobials (NAMs).
