Evertiq - Midsummer powers buses with solar cells
The system’s payback period is estimated at a mere two years, taking into consideration only the fuel consumption reduction and not the overall environmental benefits. After two years, the solar energy solution will create compound surpluses for MPK for the remainder of the panels’ life span that will outlast the lifetime of the bus.
Columnar-to-Equiaxed Transition in Metal-Matrix …
The present work is focused on the study of the effect of directional heat extraction on the silicon-carbide (SiC) distribution in zinc-aluminum matrix composites (MMCs) and on the columnar-to-equiaxed (CET) position in directionally solidified samples. To this end, a ZA-27 alloy matrix was reinforced with ceramic particles of SiC and vertically directionally solidified. The cooling rates

The Window Is Closing to Avoid Dangerous Global …
Temperatures haven’t been that high since the Miocene warming period. That low-probability but very extreme scenario could expose most of the world’s people to deadly heat stress, with 2.5 billion facing viruses linked to warming and 20 percent of the world’s species becoming extinct.
Coated carbide grades are also used in cast iron appliions, but stable conditions will also permit the use of silicon nitride and some cubic boron nitride (CBN) grades. Aluminum and other nonferrous materials can be run with uncoated carbide inserts, usually with highly positive ground chip breakers to prevent long strings of chips.
Germany’s SiC Processing GH''s request to file for self-administrative insolvencywas accepted by the district court in Aerg, Germany on 20 Deceer 2012. The company, which is the global market leader in the recycling of slurry from silicon carbide (SiC) wafers, said that it has “struggled increasingly with the continuous decline in prices and severe over-capacities in the solar sector”.
