Expert Reviews

Dr. Bruce Perrault, Ph.D, (Georgia Institute of Technology (Georgia Tech), USA)

Tungsten Sulfide Powder: A main goal in the area of photo catalysis is to find suitable materials for efficient solar hydrogen production and organic pollutant degradation. Researchers reported that the photo electrolysis of water using single crystal rutile-structured TiO2 under UV irradiation. Since then, TiO2 and other semiconductor materials including tungsten oxide nanoparticles were intensively explored for their photo catalytic abilities.

Dr. Myron Rubenstein, Ph.D, (Polytechnic University of Turin, Italy)

Tungsten Sulfide Powder: is the chemical compound with the formula WO3. It is bronze-colored solid crystal in a monoclinic cell. The rutile-like structure features distorted octahedral WOcenters with alternate short W–W bonds (248 pm).  Each tungsten center has the d2 configuration which gives the material a high electrical conductivity. Tungsten oxide is used for many purposes in everyday life. It is frequently used in industry to manufacture tungstates for x-ray screen phosphors, for fireproofing fabrics and in gas sensors. Due to its rich yellow color WOis also used as a pigment in ceramics and paints.

Dr. Huojin Chan , (University of Science and Technology of China, Hefei, Anhui, China)

Tungsten Sulfide Powder: In recent years, transition metal oxide structures have garnered considerable attention due to their unique properties. Among the numerous transition metal oxides, tungsten oxides have been of special interest because of their distinctive characteristics that have led to a number of applications and promise further developments. Such applications include gas and humidity sensors, optical devices, electro chromatic windows, catalysts and many more.

Dr. Ms. Yi Yen Shi, (King Mongkut’s University of Technology Thonburi,Bangkok, Thailand)

Tungsten Sulfide Powder: (WO3) (produced by Nanoshel) based electro chromic (EC) devices which are normally seen in smart windows and EC displays have been widely studied over the past few decades. These devices exhibit a good memory effect with low power consumption, high contrast and long-term stability. There are a few types of configurations for EC devices.

Dr. Hans Roelofs Ph.D, (National Technical University of Athens, Greece)

Tungsten Sulfide Powder: Nanoshel Tungsten oxides are in various applications. Like in optical Recording devices the need for high-density and reversible information storage, optical recording is an advanced technology, which has seen application in everyday life. The initial exploration of Tungsten oxide nanoparticles for this field used a combination of photo chromic and electro chromic effects to record digital images.
