There are many economic, environmental and production benefits related to using light as a trigger for processes.
Bigelow Aerospace and United Launch Alliance join forces to foster habitable volumes in Low Earth orbit
Droop, the decrease of efficiency with drive, is a major technology topic for InGaN-based light emitting diodes (LEDs).
Statoil presented a new subsea concept to reduce cost and increase efficiency.
Due to the need to develop efficient, low cost photovoltaics, different emerging photovoltaic technologies have been attracting increasing attention.
A new 1D gold nanowire is proposed for novel nanoelectronics by researchers in China. The design of the new structure was achieved by carefully considering the stability of 0D, 1D, and 2D gold nanostructures.
Stand-alone, supercontinuum laser source “Solea” with unmatched flexibility in repetition rate. Variants covering two spectral domains ranging from 480 to 700 nm (“Solea”) or 900 nm (“SoleaR”) are available featuring either a tunable wavelength selector or only emitting the full supercontinuum spectrum (white variants).
Adhesives and glues are essential in a wide range of applications in modern life, from buildings to vehicles, and mobile devices to biomedical applications.
Ion-gels have possible applications in organic electronics due to their favorable electronic characteristics and good thermal and chemical stability.
