Resistive sensors based on metal oxide nanostructures are very interesting because they are tiny, simple, cheap to fabricate and to use, possibly low power consuming, and can sense almost any gas. Unfortunately, this last property is not so positive, [....]
Dopamine (DA) is one of the naturally occurring catecholamine’s in the mammalian central nervous system, which acts as a vital part in neurotransmission. The changes in DA concentration can lead to serious illnesses such as schizophrenia and Pa [....]
Biochar preparation from different materials has been attached with great attention during these years. This study was conducted to prepare activated carbon fiber (ACF) from luffa through the processes i.e pre-treatment, pre-oxidation and carbonizati [....]
Calcium phosphates materials with whitlockite and apatite like structures have been studied for their potential applications in several fields of material sciences, such as biomedical diagnostics [1], Fluorescent materials [2-3], catalysts and adsorb [....]
The study on the possibility of the synthesis of iron pigments based on a waste iron(II) sulfate from the production of titanium dioxide by the Sulfate Process in Grupa Azoty Zak?ady Chemiczne “POLICE” S.A. The work uses solid wastes f [....]
The study investigated the possibility of conducting mixing process in a custom mixing system equipped with a magnetic field generator. Research installation used in this work was created to the needs of research project no. UMO- 2018/31/B/ST8/03170 [....]
Solvent extraction technology has been effectively applied for recovery and separation of a variety of metals and now plays a very significant role in hydrometallurgy and waste water treatment. Acidic organophosphorus compounds have been widely st [....]
Ammonia (NH3) is a colourless gas with characteristic odour that belongs to a group of air pollutants whose emission to atmosphere is strictly monitored and restricted. These limitations result from its high toxicity and destructive impact on the env [....]
This presentation gives a short overview of the characteristic properties of porous metals manufactured by powder metallurgy based space-holder methods. In this family of methods, a metal powder is first mixed with a filler material in the powder for [....]
Palladium(0) nanoparticles have been widely used in cross coupling reactions, including Heck reactions. For this study, we obtained palladium(0) nanoparticles in colloidal suspension using different combinations of solvents and reducing methods under [....]

Title : Design of Metal Single-Site Zeolites and their Application in Industrial and Enviromental Catalysis
Stanislaw Dzwigaj, Surface Reactivity Laboratory - Sorbonne University, France
We have earlier shown [1-2] that the incorporation of transition metal ions into vacant T-atom sites of framework zeolite is strongly favored when, in the first step, zeolite is dealuminated by treatment with nitric acid solution and then, in the sec [....]
Title : Catalysts for Ethylbenzene to Styrene: Challenges & Breakthrough
Palanichamy Manikandan, Clariant Corporation
Styrene is one of the major commodity chemicals/monomers used for the production of different polymeric materials such as polystyrene (PS), acrylonitrile-butadiene-styrene (ABS) and styrene-butadiene rubber, which find their use in several segments i [....]
Title : Conversion of Municipal Solid Waste to Green Energy: A Paramount Concern of the World
Moinuddin Sarker, Waste Technologies LLC, USA
The exponential growth of Municipal Solid Waste (MSW) along with its environmental impact is one of the most critical problems that large cities in developing countries face now-a-days. Solid Waste management in developing countries is characterized [....]

Title : Metal-Protein Hybrid Materials with Emergent Functions
Bassam Nagy Mohammed Saif, Shanxi Normal University, China
Nature is replete with examples of the building up functional nanostructures for a new generation of advanced biomaterials. Metal ion plays an important role in many of these biological systems. The sophisticated functions of metal-binding proteins h [....]
Title : Chasing Pd active species in Suzuki-Miyaura cross-coupling reactions
Priya Karna, University of Kentucky, United States
Suzuki-Miyaura (S-M) cross-coupling reactions employed with an aryl halide, organoborate, base, solvent, and a palladium (Pd) catalyst are widely employed in the applications of organic syntheses, but the mechanism behind the active species of the ca [....]
Title : Supercritical Fluids as Reaction Media for Scalable Production of Carbon Nanomaterials
Haider Almkhelfe, Kansas State University, Iraq
We have demonstrated scalable and selective synthesis of carbon nanotubes (CNTs), carbon nanofibers (CNFs), and onion-like carbon (OLC) in a batch reactor using supercritical fluids (SCF) as reaction media. The process utilizes toluene and alcohols ( [....]
Title : Development of NiZn Bimetallic Catalysts for Hydrogen Evolution via Selective Dehydrogenation of Methylcyclohexane
Anaam Al-ShaikhAli, Saudi Aramco, Research and Development Center, Saudi Arabia
Liquid organic chemical hydride is a promising candidate for hydrogen storage and its easy transport. Dehydrogenation of methylcyclohexane (MCH) to toluene (TOL) has been considered as one of the feasible cycles for hydrogen carrier, but selective [....]
