1. ICME guided study of mass transport in production and application of cemented carbides
Abstract : Cemented carbides are metallic composites consisting of a WC hard phase and a ductile binder, usually Co-based, produced by powder metallurgy and sintering. Cemented carbides are an essential part of modern material and manufacturing processes. READ MORE

2. Entropy-stabilized transition metal diborides for high-temperature applications
Abstract : Ultra-high temperature ceramics (UHTCs) are typically defined as materials with melting temperatures > 2500 °C, high chemical stability, and retained mechanical resistance at temperatures higher than 1650 °C. UHTCs include carbides and diborides of the Group IVB, VB, and VIB transition metals and are therefore used as structural or protective materials in extreme environments. READ MORE

3. Structured Carbon-Alkaline Earth Metal Halides Composites for Ammonia Storage
Abstract : NOx (NO, NO2) is one of the most harmful air-pollutants from exhaust, resulting in series of environmental problems as well as severe healthy issues for human beings. Selective catalytic reduction (SCR) system is a common approach to eliminate NOx onboard by using ammonia as a reductant. READ MORE

4. Recycling of Steel Grinding Swarf via Production of Iron Chloride Coagulants for Water Treatment
Abstract : Grinding swarf is a hazardous waste generated in the manufacturing industry when making products out of iron and steel. Annually 10-12 million tons are generated worldwide, and these numbers are projected to grow with steel production and industrialization of developing countries. READ MORE

5. Towards Abatement of Selected Emissions from Metals Manufacturing
Abstract : Although the metallurgical industry has made great strides in the reduction of unwanted emissions to the atmosphere as a result of production processes, significant challenges still exist. From a global perspective, even large reductions in emissions per produced ton become immaterial when considering that the total world production of metals continues to increase. READ MORE
