EL-Ammonium Tartrate, the ammonium salt of tartaric acid, is used in such applications as cell culture and chromatography. Ammonium tartrate has been used to displace sodium for the analysis of a modified oligonucleotide by matrix-assisted laser desorption/ionization post-source decay (MALDI-PSD). It is also utilized in electron spin resonance (ESR) dosimetry research, and has been probed […]

Ortho-phthalaldehyde (OPA) received clearance by FDA in October 1999. OPA solution is a clear, pale-blue liquid (pH, 7.5), which typically contains 0.55% OPA. OPA has demonstrated excellent microbiocidal activity in in vitro studies[2,3]. For example, it has shown superior mycobactericidal activity (5-log10 reduction in 5 minutes) compared with glutaraldehyde. The mean time required to effect […]

Carbon Fiber Reinforced Polymer Composites (CFRP) are lightweight, strong materials used in the manufacturing of numerous products used in our daily life. It is a term used to describe a fiber-reinforced composite material that uses carbon fiber as the primary structural component. It should be noted that the “P” in CFRP can also stand for […]

The main characteristic of thermosets (literally setting under heat) is that they require curing, when they undergo a molecular cross-linking process which is irreversible and renders them infusible. They therefore offer high thermal stability, good rigidity and hardness, and resistance to creep. This also means that, once cured, the resin and its laminate cannot be […]

The photocatalytic properties of anatase, one of the three naturally occurring forms of titanium dioxide, were discovered in Japan in the late 1960s. Under the influence of the UV-radiation in sunlight, it can decompose organic pollutants such as bacteria, fungi and nicotine, and some inorganic materials into carbon dioxide. The catalytic effect is caused by […]

Is it a solar cell? Or a rechargeable battery? Actually, the patent-pending device invented at The Ohio State University is both: the world’s first solar battery. In the October 3, 2014 issue of the journal Nature Communications, the researchers report that they’ve succeeded in combining a battery and a solar cell into one hybrid device. […]

Hydraulic fracturing fluids commonly consist of water, ‘proppants’ and chemical additives that open, enlarge and maintain fractures within the rock formation. The proppants – sand, ceramic pellets or other small incompressible particles – hold the newly created fracture open. The fracture widths are generally equal to a few diameters of the grains used in the […]
