Low-cost, continuous seismic monitoring system to support emission reduction efforts

Added: 08.11.2021 21:39 | 221 views | 0 comments

Researchers have developed a continuous seismic monitoring system that could monitor multiple geothermal or carbon storage reservoirs over a relatively large area in real time. A small seismic source generates repeated 'chirps,' which can be detected by fiber-optic cables within a radius of 80 km from the source. Field experiments showed that temporal changes in monitored reservoirs were captured with high accuracy.

Environmentally friendly ways to cool homes

Added: 08.11.2021 21:39 | 204 views | 0 comments

The summer of 2021 in Western Canada was one of the hottest on record. In the Canadian province of British Columbia alone, 59 weather stations registered their hottest temperatures ever on June 27. For those lucky enough to have air conditioners, keeping their homes cool during the heat dome was relatively easy. However, the comfort lasted only until the utility bills arrived. As a result of heatwaves around the world, global electricity demand increased by five per cent so far in 2021 and it is expected to continue to increase annually.

Novel quantum effect discovered in naturally occurring graphene

Added: 08.11.2021 21:39 | 208 views | 0 comments

Under special circumstances, the electrical resistance of a material can adopt a fixed value that is independent from the basic material properties and 'quantized'. This 'quantization' normally occurs within strong magnetic fields at very low temperatures when electrons move in two-dimensions. Now, a research team has succeeded in demonstrating this effect at low temperatures in the almost complete absence of a magnetic field in naturally occurring double-layer graphene, just two atoms thick.

A new solid-state battery surprises the researchers who created it

Added: 08.11.2021 21:39 | 194 views | 0 comments

Engineers created a new type of battery that weaves two promising battery sub-fields into a single battery. The battery uses both a solid state electrolyte and an all-silicon anode, making it a silicon all-solid-state battery. The initial rounds of tests show that the new battery is safe, long lasting, and energy dense. It holds promise for a wide range of applications from grid storage to electric vehicles.

Carbon fibers electrical measurements pave way for lightning strike protection technologies

Added: 08.11.2021 21:39 | 206 views | 0 comments

Carbon fiber reinforced polymer composite structures are important in several industries, yet the electrical behavior of a composite is challenging to measure or predict because of the electrical conductivity of constituent carbon fibers and the composite's complex hierarchical microstructure. Researchers report a direct measurement of the transverse electrical resistivity of a single carbon fiber. The researchers combined a precise sample preparation with a technique called the van der Pauw method to accomplish this challenging measurement.
