SPEARFISH, S.D. (AP) — A junior mineral exploration company is making a new push to find gold in the Black Hills.Solitario Zinc Corp. arrived in Spearfish in July. Todd Christensen, a geologist with Solitario, says the business was invited to assess some claims from a team of investors and saw it as an opportunity...
The University of Queensland has made a groundbreaking advancement in producing composite glass, potentially eliminating the issue of cracked phone screens.However, Led by Dr. Jingwei Hou, Professor Lianzhou Wang, and Professor Vicki Chen, an international team of researchers has developed a method for creating next-generation composite glass for various applications, including LED lighting,...
Our electrical supply depends heavily on high-voltage direct current cables that can efficiently transfer electricity across great distances. Therefore, improving their performance is a significant challenge. Researchers from the Technology University of Chalmers in Sweden have developed a novel insulation material that is up to three times less conductive with the intention of enhancing...
The material keyboard realized by the ETH Zurich researchers. By applying electric voltages (“keys”) at different points, the magic-angle graphene can become locally superconducting (electron pairs) or isolating (barrier on the right).

Bentley Systems, Inc. (Bentley) and Siemens Energy have unveiled a collaborative solution called Assets Performance Management for Oil & Gas (APM4O&G), which utilizes intelligent analytics to reduce operating expenses related to oil and gas assets. This joint solution combines Bentley's advanced asset performance software capabilities (AssetWise) with Siemens Energy's technology and service expertise to...
The new material is based on polyethylene, which is used for insulation in existing HVDC cables. Now, by adding very small amounts – 5 parts per million – of the conjugated polymer known as poly(3-hexylthiophene), the researchers were able to lower the electrical conductivity by up to three times.

Researchers from Brown University and the University of Maryland have developed a new material derived from trees that could replace liquid electrolytes in next-generation batteries. Published in the journal Nature, the study introduces a thin and flexible solid ion conductor made by combining copper with cellulose nanofibrils, which are polymer tubes derived from wood....
A study (An international stock), revealed that CO2 escapes from oil refineries were as high as, 1.3 Gt in 2018 and could reach 16.5 Gt from 2020 to 2030. From the results, the investigators suggest unique mitigation techniques for such refineries in various regions and ages. The results appear today (20 August 2021) in...
