First, let’s look at the deal and how it was born. It came from a very good place and a good man, Steve Witkoff who has a ...

Climate change left its signature on the atmosphere early in the industrial revolution, reveals a thought experiment ...

Scientists are using trapped ions in cutting-edge experiments to hunt for signs of an undiscovered particle that might help ...

Two studies fill in gaps about the cosmos’s ordinary matter. One maps it all, even the “missing matter.” The other details one of its hiding spots.

Why do some changes in nature unfold gradually, while others occur in the blink of an eye? Rust forming on metal is a slow, ...

We have proposed and designed a partially suspended silicon microring resonator (MRR) to improve the energy efficiency for inducing phase change of $\mathrm {S}\ ...

Efficient and long-term stable triplet–triplet annihilation upconversion (TTA-UC) can be achieved by effectively protecting the excited organic triplet ensembles from photoinduced oxygen quenching, ...

In order to optimize the design parameters of inverter, an optimization method of inverter switching frequency was proposed. In this paper, the three-phase voltage type bipolar SPWM bridge inverter ...

Three mathematical models of air quality (CMAQ, CMAQ-MADRID, and REMSAD) are applied to simulate the response of atmospheric fine particulate matter (PM2.5) concentrations to reductions in the ...
