A review on antimicrobial mechanism and applications of graphene-based materials.

In recent years, graphene and its derivatives, owing to their phenomenal surface, and mechanical, electrical, and chemical properties, have emerged as advantageous materials, especially in terms of their potential for antimicrobial applications. Particularly important among graphene's derivatives is graphene oxide (GO) due to the ease with which its surface can be modified, as well as the oxidative and membrane stress that it exerts on microbes. This review encapsulates all aspects regarding the functionalization of graphene-based materials (GBMs) into composites that are highly potent against bacterial, viral, and fungal activities. Governing factors, such as lateral size (LS), number of graphene layers, solvent and GBMs' concentration, microbial shape and size, aggregation ability of GBMs, and especially the mechanisms of interaction between composites and microbes are discussed in detail. The current and potential applications of these antimicrobial materials, especially in dentistry, osseointegration, and food packaging, have been described. This knowledge can further drive research that aims to look for the most suitable components for antimicrobial composites. The need for antimicrobial materials has seldom been more felt than during the COVID-19 pandemic, which has also been highlighted here. Possible future research areas include the exploration of GBMs' ability against algae.

Adopting net-zero in emerging economies.

In recent years, rapid reduction in natural resources alongside climate change has prompted industries to adopt sustainable operational practices. Globalization is arguably a boon for people and societies worldwide but has also led to significant disruptions to our natural ecosystem. Consequently, it has caused environmental concerns and issues around public health. The net-zero economy has recently emerged as a pivotal way to conserve the environment, mitigate health issues and address sustainable development goals (SDGs). The extant literature and relevant industrial reports have shown that automobiles significantly contribute to greenhouse gas emissions. Therefore, the current study is conducted to identify the critical success factors (CSFs) of net-zero adoption with respect to the automobile industry. The fuzzy decision-making trial and evaluation laboratory (DEMATEL) technique is applied to establish a dyadic relationship (cause-effect) among the identified CSFs. The top three CSFs are found to be focus on research and development activities, International Collaborations and Strategic Planning and Effective Roadmap. Finally, this study provides theoretical and practical implications for relevant industries to implement net-zero effectively.
