For all of the tumultuous revolutions in wireless technology over past several decades, there have been a couple constants. One is overcrowding radio bands, and other are attempts to escape that congestion by exploiting higher frequencies. And today, as engineers roll out 5G plan for 6G wireless, they find themselves at crossroads.

We assess routes to a diamond-based quantum computer, where we specifically look towards scalable devices, with at least 10 linked quantum gates. Such a computer should satisfy the deVincenzo rules and might be used at convenient temperatures. The specific examples that we examine are based on the optical control of electron spins. For some such devices, nuclear spins give additional advantages...

It is now widely believed in neutrino physics that neutrino oscillations are influenced by the presence of matter, modifying the energy spectrum produced by a neutrino beam traversing the Earth. Here, we will discuss the reverse problem, i.e., what could be learned about the Earth’s interior from a single neutrino baseline energy spectrum, especially about the Earth’s mantle. In the end of the ...

The recovery and removal of the most organic acids in liquid solutions is usually treated with fixed-bed adsorption processes. Among many adsorbents, Granular Activated Carbon (GAC) is used to remove organic pollutants such as Benzoic Acid (BA) from wastewaters conventionally. In this research, adsorption isotherm curves of BA onto GAC at varying temperatures 25-60 °C are developed and the ...
