⑤Hydrogen comes in different forms, and its cleanliness depends on how it’s made. Although hydrogen is naturally found in the world, the one we need for energy is not common. Companies have to get hydrogen from other sources, mainly from fossil fuels, which often causes pollution. ...
Sanxingdui Ruins, located on the south bank of the Yazi River in the northwest of Guanghan, Deyang, show the appearance and development level of the ancient Shu civilization thousands of years ago. The site is the remnants of an ancient capital, which has the richest cultural connotation and ...
Here, we conduct experiments to replicate subglacial erosion involving both gentle and high-energy crushing of Subglacial Lake Whillans sediments and the subsequent addition of anoxic water. We find that substantial quantities of reduced species, including hydrogen, methane, acetate and ammonium and ...
and these sites are particularly sensitive to Cdk12 loss. The cumulative effect of these sites accounts for the enhanced level of sensitivity of HR gene manifestation to Cdk12 loss, and we find that this mechanism is definitely conserved in human being tumors harboring Cdk12 ...
Water and the bad smelling molecule hydrogen sulphide do not seem to have a lot in common at first sight. However, when investing a little energy, some differences disappear. At first glance, the ...
The ionization of hydrogen in a circularly polarized electric field consists of the electron escaping over a rotating Stark saddle. The escape is mediated by the stable and unstable manifolds of a normally hyperbolic invariant manifold associated with the saddle. General principles ...
Today, around 95% of the world’s hydrogen is still produced from fossil fuels (including methane: CH4)1. Specifically, we produce hydrogen through a process called “steam methane reforming” (SMR), which consists of producing a reaction between methane and water giving CO2on one side and H2...
which is not attainable by any combination of common, hydrogen-rich biomolecules. Csp2-based Cqunits comprise familiar unsaturated functional groups (that is, C2C = O, COOH, CONH, COOR, CarO and CarC, and C2C = C), resonating at δC ≈ 95–235 ppm. The carboxyl group COOH...
which showed an enrichment of signal transduction mechanisms among co-excluders. By investigating the taxonomic distribution of all 147 autoinducer BGCs detected, we find that the majority were harboured by species from theLachnospiraceaefamily (97/147, 66%). Further grouping of the BGCs by their...
Yuan Chuanwei has been a one-man show for over 10 days. On Jan. 26, one day after the Spring Festival when he was on vacation in his home city of Yancheng, he received a call for an order for 1,000 hydrogen peroxide sterilizers from his factory in Suzhou. The sterilizers, which we...
