    ABSTRACT: Vinyl ester resins (VERs) are high-performance unsaturated resins derived by the addition reaction of various epoxide resins with α - β unsaturated carboxylic acids. These resins have always been classified under unsaturated polyester resins. However, VERs have remarkable corrosion resistance and superior physical properties as compared with these conventional polyester resins, which make VERs a class of their own and hallmark of today ’ s resin industries. Hence, there is a need to review the available literature on this important class of thermosetting resins separately. In this article, an attempt is made to review the state of the art of VERs, including synthesis, characterization, curing, thermal, chemical, oxidative properties, and applications. The main focus is on the latest developments in this area.

    ABSTRACT: An increased interest in the removal of heavy metal ions from aqueous media is encountered due to their toxicity and negative impacts on ecosystems, human health and economic activities. A variety of processes may be used for the removal of heavy metal ions from water and wastewater, such as chemical precipitation, ion exchange, adsorption, membrane processes, etc. However, the removal efficiencies of heavy metals by adsorption depend on several factors such as: initial loads of heavy metals in the influent, purpose of treatment (drinking/industrial water production, wastewater treatment for disposal or recycling), costs of the overall process, and properties and conditions for regeneration of the sorbent materials. In this context, the use of polyurethane foams as heavy metal ion sorbents is of a special interest because they provide versatile applications in heavy metal effluent management. This study reviews relevant published researches that are concerned with new sorbents based on polyurethane foams applied in batch and dynamic systems for separation and/or preconcentration of heavy metal ions in environmental aqueous media. This review is divided into the following sections: synthesis of polyurethane foams; physical and chemical properties of polyurethane foams; preconcentration of pollutant metal ions from environmental aqueous media by different types of polyurethane foam (untreated, loaded, reacted and composite polyurethane foams); the applicability of sorbents based on polyurethane foams for water and wastewater treatment; comparison of sorbents based on polyurethane foam with other sorbents for heavy metal ion removal.

    ABSTRACT: Petroleum resources are limited and stringent environmental concerns are increasing; biodegradable materials made from renewable agricultural resources such as carbohydrates, starch and proteins are attracting much attention for sustainable development and environmental conservation. As per the annual production of wheat in India, it is the second largest producer in the world after China. In this paper, we explore the possibility of wheat protein known as gluten as a promising substitute for petroleum-based plastics and environment-friendly thermosetting composites. Plant proteins from wheat show an advantage for use as films and plastics because of their abundant resources, low cost, good biodegradability and suitable properties like rheological properties, water sensitivity, sound absorption and thermal behavior. The paper aims to explain the extraction of gluten and to review the blending of gluten with different plasticizers such as glycerol, water and some cross-linking agents to enhance the above-mentioned properties. An extensive review of the existing literature reveals that wheat gluten (WG)-based bioplastics are nontoxic and fully biodegradable, whatever the technological process is applied; thus, the paper also discusses the biodegradability of WG-based bioplastics. We conclude the paper by incorporating a critical summary of the various parameters and chemicals used to enhance the properties of gluten-based composites.

    ABSTRACT: Multi-impeller stirred vessels are widely used for industrial applications. Based on the numerous studies that reported the motivation and importance of studies on multi-impeller systems, a systematic study was conducted to identify the focus and objectives of research and types of experiments conducted using multi-impeller systems. Researchers mainly focused on the effects of impeller spacing, off-bottom clearance, and type of impeller combinations. Most experiments were conducted on power number, power consumption, gas hold-up, and gas-liquid mass transfer. Research works have not exhausted all impeller-type combinations and there are still opportunities for future work. Computational fluid dynamics studies involving multi-impeller systems are also still lacking owing to flow complexities. This work can serve as a roadmap for future study themes.

    ABSTRACT: Artificial neural networks (ANN) provide a range of powerful new techniques for solving problems in sensor data analysis, fault detection, process identification, and control and have been used in a diverse range of chemical engineering applications. This paper aims to provide a comprehensive review of various ANN applications within the field of chemical engineering (CE). It deals with the significant aspects of ANN (architecture, methods of developing and training, and modeling strategies) in correlation with various types of applications. A systematic classification scheme is also presented, which uncovers, classifies, and interprets the existing works related to the ANN methodologies and applications within the CE domain. Based on this scheme, 717 scholarly papers from 169 journals are categorized into specific application areas and general (other) applications, including the following topics: petrochemicals, oil and gas industry, biotechnology, cellular industry, environment, health and safety, fuel and energy, mineral industry, nanotechnology, pharmaceutical industry, and polymer industry. It is hoped that this paper will serve as a comprehensive state-of-the-art reference for chemical engineers besides highlighting the potential applications of ANN in CE-related problems and consequently enhancing the future ANN research in CE field. Keywords: artificial neural networks; chemical engineering applications; modeling; optimization

    ABSTRACT: An increasing environmental concern for diesel particulate emissions has led to the development of efficient and robust diesel particulate filters (DPF). Although the main function of a DPF is to filter solid particles, the beneficial effects of applying catalytic coatings in the filter walls have been recognized. The catalyzed DPF technology is a unique type of chemical reactor in which a multitude of physicochemical processes simultaneously take place, thus complicating the tasks of design and optimization. To this end, modeling has contributed considerably in reducing the development effort by offering a better understanding of the underlying phenomena and reducing the excessive experimental efforts associated with experimental testing. A comprehensive review of the evolution and the most recent developments in DPF modeling, covering phenomena such as transport, fluid mechanics, filtration, catalysis, and thermal stresses, is presented in this article. A thorough presentation on the mathematical model formulation is given based on literature references and the differences between modeling approaches are discussed. Selected examples of model application and validation versus the experimental data are presented.

    ABSTRACT: Investigations of metabolic uncouplers in growth systems such as activated sludge treatment are increasing because of their ability to decrease biomass growth. As of 2011, more than 10 metabolic uncouplers were reported to significantly decrease biomass yield by between 21% and 87%. In this paper, we present a detailed review of metabolic uncoupling, different metabolic uncouplers, current applications in waste water treatment systems and their possible use in biological air pollution control systems such as biofiltration in order to improve the substrate degradation rate. This paper will be useful for those who are interested in using metabolic uncouplers to improve the performance of growth or non-growth systems.

    ABSTRACT: Installation of large-scale compressed air energy storage (CAES) plants requires underground reservoirs capable of storing compressed air. In general, suitable reservoirs for CAES applications are either porous rock reservoirs or cavern reservoirs. Depending on the reservoir type, the cyclical action of air injection and subsequent withdrawal produces temperature and pressure fl uctuations within the reservoir. An accurate prediction of these fl uctuations is essential for the design of the reservoir and its associated turbomachinery. Being mutually dependent, the selection of the turbomachinery and reservoir characteristics must be conducted simultaneously to obtain an integrated cost-effective plant. The present review is intended to encompass the pertinent literature on the temperature and pressure variations within CAES reservoirs. The principal experimental and operational data sources are described, as well as important results of theoretical modeling efforts. Conclusions derived from those investigations and their relevance to CAES plant designs are discussed.
