Isotopes are atoms of the same element with the same number ... This is done using a two-step reduction, first with hydrogen, then with calcium. In short, enriching uranium is like trying to separate ...

The growth rate of the atmospheric abundance of methane (CH 4) reached a record high of 15.4 ppb yr −1 between 2020 and 2022, but the mechanisms driving the accelerated CH 4 growth have so far been ...

Teeth can tell a life’s story, even when they’re 150 million years old. One of the new frontiers in paleontological research ...

Understanding the leaching behavior of arsenic (As) and selenium (Se) in coal fly ash is important in evaluating the potential environmental impact of coal fly ash. Batch experiments were employed to ...

While the Standard Model (SM) describes all known fundamental particles and many of the interactions between them, it fails ...

A force that couples electrons and neutrons could be an addition to the Standard Model, and a new study places an upper limit ...

S cientists have found an intriguing discrepancy in the way electrons behave in different calcium atoms. The difference ...

Use precise geolocation data. Actively scan device characteristics for identification. Store and/or access information on a ...

Using five isotopes of calcium in two different states of charge, the researchers measured atomic transitions to a degree that left some wiggle room for a small undescribed force governed by a ...

Abstract. Calcium silicate-based root canal sealers have been developed in powder/liquid or premixed ready-to-use forms. The evaluation of the physico-chemical properties of a prototype powder/liquid ...
