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 […]

What is Prepreg? Composite components now account for up to 85% of today’s Formula 1 cars, but only roughly 20% of the weight. An achievement only made possible by continuously exploiting and developing the capabilities of carbon fiber to manufacture intricate parts. These are built by laying up individual plies of carbon fiber prepreg on […]

Carbon fiber composites (also called carbon-fiber reinforced plastics or CFRP) are finding their way into new applications as industries demand materials with ever-higher strength-to-weight ratios, corrosion resistance, and workability. Over the past 60 years, CFRPs have been increasingly used to replace metal in applications where light weight has outsized value (capable of supporting prices that […]

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 […]

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). Ammonium tartrate is also utilized in electron spin resonance (ESR) dosimetry research, and has been […]

TOKYO, Oct. 2, 2017 /PRNewswire/ — Researchers from Tokyo Institute of Technology (Tokyo Tech) have discovered superconductivity in thin films of titanium oxide (Ti4O7) and gamma-phase trititanium pentoxide (γ-Ti3O5). The achievement advances fundamental knowledge of nanomaterials that could one day be used in the development of ultrafast computers. Many of us are familiar with titanium […]

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 […]
