Special Issue Information

Dear Colleagues,

The world is changing faster than ever before, and technological advancement is the main driving force. Environmental sustainability, alternative energy, development of smart materials, state-of-the-art separation technology, and novel reactor and process design are the major advancing areas in recent times, to the aim of satisfying the increasing market requirements for specific end-use properties of the products required by the consumers. For the successful operation of any industrial process or plant, particularly chemical and process ones, it has become essential to consider the social impacts on environmental and sustainability issues. To achieve an environment friendly atmosphere, sustainability problems spanning multiple scales—from molecular levels through to chemical plants and finally to enterprises and the macroeconomic level—need to be addressed. In such a context of globalization vis à vis activities, services, and product impacts on the environment, sustainability may be redefined. It is, however, difficult to find useful sustainability criteria and ready-to-use guidance tools for the design of products, processes, and production systems for maintaining a balance between the environment and the ‘molecules into money’ concept. Chemical engineers have a distinctive role to play in the planning, analysis, and implementation of sustainable developments with a vision to save the environment. The articles to be published in this Special Issue are selected articles that will be presented at the International Symposium on Chemical Engineering—Environment, Sustainability and the Future, 22-24 December 2023, to be held at the University College of Science & Technology, Kolkata, India. The International aims to bring together researchers, academicians, professionals, policymakers, scientists, industry delegates, research scholars, and UG/PG students from all over the world under one roof to interact, deliberate, share, and present their research work, ideas, and innovations related to recent advances in environment, energy, sustainability, and advanced materials.

A combined theoretical and experimental study is presented to investigate the interplay of forces in the spin-dewetting process in order to achieve enhanced control over droplet generation. In this regard, toluene–polystyrene (PS) film is spin dewetted on a solid substrate to generate an array of droplets. The underlying mechanisms of the spin dewetting of the films into the droplets are explained with the help of a theoretical model followed by a long-wave linear stability analysis (LWLSA). Stabilizing forces like solution viscosity and surface tension play essential roles. The study uncovers that the centripetal force stretches the film radially outward, before it becomes ultrathin and undergoes dewetting under the influence of van der Waals forces, while the surface tension force acts as a stabilizing influence. On the other hand, the viscous force kinetically stabilizes the system to expedite or delay drop formation on the substrate. An imbalance of these factors ultimately decides the droplet spacing, which leads to interesting morphologies such as singlet, doublet, triplet, and clusters of droplets at specific PS concentrations in the range 0.0001–0.0005%, with a ~10–14 nm average droplet height. The experimental data revealed that, at ~3000 rpm, PS (0.01–0.1%) results in critical droplet spacings of λmax~98–172 μm, leading to immediate dewetting and uniform droplet formation. Our theoretical predictions are in close agreement with the experimental results, validating the present model. The insights gained in this work provide a foundation by presenting a robust framework for controlled droplet generation by optimizing process parameters to achieve the desired droplet size, distribution, and uniformity. The findings have broad applications in material science, biomedical engineering, and related disciplines. Full article
