Over recent years, there has been a significant increase in the use of immobilized biocatalysts in many fields of science, life and industry, mainly due to the improvement of the stability and activity of enzymes at harsh reaction conditions as well possibility of their reuse. Th [....] » Read More
Title : Low temperature synthesis and inkjet printing of photoactive TiO2 on polymeric substrates
Hesam Maleki, University of Liverpool, United Kingdom
A low-temperature method was used to prepare and inkjet-print photoactive TiO2 films on polymeric substrates using a commercial inkjet printer. The as-prepared substrates were used in a microfluidic device fabricated with selective transmission laser welding. The catalytic activi [....] » Read More
Title : Pyrazole as a corrosion inhibitor for carbon steel in aqueous media
Mohamed A Abbas, Egyptian Petroleum Research Institute, Egypt
The inhibitory impact of pyrazolin derivative (Pz) on corrosion of carbon steel in 1 M HCl was examined by potentiodynamic polarization method and electrochemical impedance spectroscopy (EIS). The hindrance effectiveness of Pz on corrosion of carbon steel in 1 M HCl arrangement i [....] » Read More
Title : Using polyisobutylene supported sulfur ligands for metal sequestering
Hassan S Bazzi, Texas A&M University at Qatar, Qatar
Whether it is industry, agriculture, research experiments, or just ordinary activities, modern societies in the 21st century produce unwanted waste. In some cases, this waste is concentrated and can be easily dealt with. In other cases, such waste can be minimized; this ha [....] » Read More
Title : Inorganic oxide systems with immobilized laccase as tools for dyes decolorization
Katarzyna Jankowska, Poznan University of Technology, Poland
Wastewaters containing dyes are toxic pollutants released to environment, which can be dangerous for living organisms and human health. They can cause various diseases, for example cancers, allergies and neurological disorders. Many industries, such as textile and automotive indu [....] » Read More
Title : Optimal design and sensitivity analysis of Gas-solid reactor for efficient H2 storage
Di Wang, Northwest University, China
Metal hydride (MH) has large hydrogen storage capacity and mild operation conditions, which is considered to be a promising method for H_2 utilization. Since the hydrogenation/dehydrogenation is reversible chemical reaction with strong thermal effect, the design and optimization [....] » Read More
