Effects of accelerators on the cure characteristics
Diphenylguanidine (DPG) is most frequently used as a secondary accelerator to synergise with thiazole accelerators. As secondary accelerator, DPG in combination with MBTS contributes to a powerful cure activation effect that imparts high modulus, tensile strength, dynamic and aging properties of rubbers [5]. In MBTS acceleration systems,
Nuclear fusion firm Pulsar fires up a UK-built hybrid rocket engine. UK nuclear fusion outfit Pulsar Fusion has fired up a chemical rocket engine running on a combination of nitrous oxide oxidiser, high-density polyethylene fuel and oxygen. The acceptance tests of the UK-built rocket were conducted at COTEC, a UK Ministry of Defence site at
Biomass combustion and co-firing for electricty and heat
Combustion-based CHP plants for countries that possess district heating systems (Nordic countries in Europe), large pulp and paper or food industries (e.g. Brazil, USA). At present, some 230 power and combined heat and power (CHP) plants use co-firing, mostly in northern Europe and the United States (Platts, 2011b), with a capacity of 50-700 MWe.

Hybrid organic inorganic lead halide perovskite semiconductors of the form CsyFA1−yPb(BrxI1−x)3 are promising candidate materials for high-efficiency photovoltaics. Notably, cation and anion substitution can be used to tune the band gaps to optimize performance and improve stability. However, multi-component Special issue in honour of Seth Marder

DC switching power can generate audible noise, which is often heard as a slight whistle. Where does audible noise come from, and how can it be reduced or eliminated? This article will describe simple ways to prevent noise while measuring and designing an application. Read on to find common weak points in existing or planned PCB designs for DC power supply circuits.
