The leather industry is an essential sector, especially in countries with highly developed livestock as they use rawhide to produce high-valued leather products. The leather-making process uses different chemicals and is a source of environmental pollution if the wastewater is not properly treated. Therefore, the purpose of this study is to analyze a Moving-Bed Biofilm Reactor (MBBR) as a new technology for the biological tr Read More

Sewage sludge shows excellent potential as pyrolysis feedstock in generating valuable products such as Activated Carbons (ACs). In this mini-review the preparation of sewage sludge- ACs by two kinds of pyrolysis conventional and microwave heating is presented and discussed. The main difference between conventional pyrolysis and the microwave-assisted method is the way the heat is generated, and both can provide A Read More

Continuously growing environmental issues have become a significant problem in the world. These ecological issues deteriorate our day to day life and are responsible for serious diseases. Also, the growing industrialization of the world has steeply risen and demanding petroleum products for their modernization. Economic development has also resulted in a considerable rise in energy demand. Biodiesel, a less polluting and su Read More

In their search for an alternative to commercial adsorbents, much research is turned to the local biomass-based materials such as agricultural residues and assimilated derivatives. However, natural biomass due to its low specific surface area must first undergo several pre-treatments. Among the newly emerging electric techniques for environmental applications, those who operate at atmospheric pressure (Non-therm Read More

Considering the global environmental issues, various factors such as industrial ecology, eco-efficiency, and chemical engineering are being combined to develop advanced material known as bio-based or natural polymer-based materials. The environment and the cost-effective factors are now propelling the inclination in the direction of greater utilization of bio-based polymers and materials. Biobased materials are gen Read More

Biochar-Amended Composting (BAC) plays an integral role in sustainable agricultural practices due to its multiple benefits in crop production, soil nutrient retention, carbon sequestration and environmental protection. Although accepted as a traditional method, there is a lack of understanding in defining its suitability and efficiency in terms of various base-materials and conditions. Being two carbon-based entities with plentiful n Read More

Ascidians (tunicates) are widely recognized as one of the most prolific producers of bioactive natural products in the marine environment. This present study reviewed the chemical diversity of marine ascidians from the Aplidium genus and their pharmacological applications since Jan 2005. The resources of this genus from China Seas, including the changes of their names in the family Polydinidae were also summarized in thi Read More

Calixarenes are macrocyclic compounds that form complexes with ions and neutral molecules. Association with ammonium cations and calixarenes is directed by coulombic forces, hydrogen bonding, N+-C-H---π interactions and van der Waals interactions. Calixarenes are stronger acids than corresponding phenols and react with aliphatic amines by proton-transfer and the ammonium cations can be placed as exo or endo-cali Read More

The diverse library of biologically active organic compounds is composed majorly of heterocyclic compounds. Nature provides a variety of pharmacologically active compounds consisting of N-heterocycle motif, such as Noscapine (anti-cancer), Morphine (analgesic), Chelerythrine (antibacterial), etc. which are the elementary structural units of marketed drugs in the present era. One such “N-heterocyclic” promisin Read More

Cosmeceuticals are cosmetic products containing biologically active ingredients with attractive properties (e.g. anti-oxidant, anti-inflammatory, anti-aging, photoprotective activity, etc.). The aim of these compounds is to offer pharmaceutically therapeutic benefits. The active ingredients can be extracted and purified from natural sources, including plants and animals, or be obtained by biotechnological methodologies (e.g. fer Read More

As a medicinal fungus, Inonotus obliquus (IO) has been widely used in the treatment of cancer and digestive system diseases. Despite the progress that has been made in the studies of IO and its active compounds, their applications in the treatment of other important clinical diseases, such as cardiovascular diseases, which are major global issues with limited treatment strategies, are seldom reported. This review summarizes t Read More
