Mercury (II) iodide is a chemical compound that exists in red-orange crystals. It is highly reactive to lead salts, iodoform, chlorides, light, heat, hydrogen peroxides and copper salts. Unlike mercury (II) chloride, it is hardly soluble in water.
All that time spent playing with plastic bricks as a kid may finally be paying off, as tiny composite blocks developed by MIT have been used to create a lightweight structure and could lead to much more design freedom in composite manufacturing.

The Malvern Viscosizer 200 system can automatically measure viscosity in extremely low sample volumes and is also capable of measuring molecular size.
Drug efficacy and patient experience are given high precedence during the development of injectable biotherapeutics.
Aluminium gallium indium phosphide is a semiconductor material that provides a platform for the development of novel multi-junction photovoltaics and optoelectronic devices as it span a direct bandgap from deep ultraviolet to infrared.
A recent paper by researchers from Rice University provides the first complete mechanical modelling of carbyne - a promising form of carbon which could outperform diamond, nanotubes and even graphene, taking the title of the strongest material in existence.

Lead selenide is a semiconductor material that forms cubic crystals of the NaCl structure. It performs efficiently at low temperature without the need for cooling. It naturally occurs in the mineral clausthalite.
Silicon-germanium is a general term for Si1-xGex alloy that consists of any molar ratio of germanium and silicon. It is manufactured on silicon wafers by using conventional silicon processing toolsets.
Tin dioxide is an inorganic compound with the chemical formula SnO2. It mainly occurs in the mineral, cassiterite. It is a colorless, amphoteric and diamagnetic solid that is usually considered as an oxygen-deficient n-type semiconductor.
Stellite alloys are a group of cobalt-chromium 'super-alloys' consisting of complex carbides in an alloy matrix predominantly designed for high wear resistance and superior chemical and corrosion performance in hostile environments.
