Advanced Functional Materials, EarlyView.Pullulan, a biomass‐derived polysaccharide, is transformed into transparent optical fibers using a solvent‐free borax hydrogel‐spinning method. The fibers outperform PMMA with ≈200 MPa tensile strength and 200 °C stability, while uniquely guiding visible‐to‐NIR light and enabling additive‐free humidity sensing.

Recent Trend of Vacuum Circuit Breakers
Journal of the Vacuum Society of Japan, 2009 The recent trend in the development and the application of Vacuum Circuit Breakers (VCBs) as an environmental friendly equipment for electric power transmission and distribution is described. Using VCB's for circuit breakers and switchgear and extending the range of application of VCB's lead to reduce the usage of SF6 gas, whose global warming ...

The suitability of N2 to replace SF6 in a triggered spark-gap switch for pulsed power applications [PDF]
, 2009 The high dielectric strength of sulphur hexafluoride (SF6) when compared with other gases, coupled with safety benefits such as non-flammability and non-toxicity, has seen the widespread use of SF6 for the insulation of switching components. However, SF6

Conductance‐Dependent Photoresponse in a Dynamic SrTiO3 Memristor for Biorealistic Computing
Advanced Functional Materials, EarlyView.A nanoscale SrTiO3 memristor is shown to exhibit dynamic synaptic behavior through the interaction of local electrical and global optical signals. Its photoresponse depends quantitatively on the conductance state, which evolves and decays over tunable timescales, enabling ultralow‐power, biorealistic learning mechanisms for advanced in‐memory and ...
