There are several ways the industry is addressing this energy crisis. First, computing hardware has gotten substantially more energy efficient over the years in terms of the operations executed per watt consumed. Data centers’ power use efficiency, a metric that shows the ratio of power consumed for computing versus for cooling and other infrastructure, has been reduced to 1.5 on average, and even to an impressive 1.2 in advanced facilities. New data centers have more efficient cooling by using water cooling and external cool air when it’s available.

Unfortunately, efficiency alone is not going to solve the sustainability problem. In fact, Jevons paradox points to how efficiency may result in an increase of energy consumption in the longer run. In addition, hardware efficiency gains have slowed down substantially, as the industry has hit the limits of chip technology scaling.

Small-angle scattering (SAS) is a powerful technique for studying nanoscale samples. So far, however, its use in research has been held back by its inability to operate without some prior knowledge of a sample’s chemical composition. Through new research published in The European Physical Journal E, Eugen Anitas at the Bogoliubov Laboratory of Theoretical Physics in Dubna, Russia, presents a more advanced approach, which integrates SAS with machine learning algorithms.

Prussian blue (PB), a well-known pigment used to dye jeans, has been recognized as an emerging material for next-generation batteries. A team of researchers, led by Professor Hyun-Wook Lee in the School of Energy and Chemical Engineering at UNIST has made a significant breakthrough in the development of low-cost, high-performance lithium-ion batteries (LIBs) using PB, leading to significantly reduced battery prices.

Bismuth being used this way can lead to flying cars or spacecraft face_with_colon_three

The nuclear magnetic resonance in bismuth metal powder has been observed from 9 to 19 Mc/sec at 4.2\ifmmode^\circ\else\textdegree\fi{}K. The isotropic and anisotropic Knight shifts and the quadrupole coupling constant have been determined as (−1.25\ifmmode\pm\else\textpm\fi{}.30)%, (−0.3\ifmmode\pm\else\textpm\fi{}0.3)%, and 2.10\ifmmode\pm\else\textpm\fi{}.05 Mc/sec, respectively. The intrinsic linewidth was found to be 130\ifmmode\pm\else\textpm\fi{}20 kc/sec. A technique is developed to take into consideration the broadening of the observed lines due to the combined effects of the magnetic dipolar broadening and the width due to the quadrupolar splitting of each line.

Particle accelerators are pricey, but their cost comes with good reason: These one-of-a-kind, state-of-the-art machines are intricately designed and constructed to help us solve mysteries about what makes up our universe. Still, the scientists and engineers building these machines must do their best to save where they can. Researchers at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility are supporting this mission by figuring out how to optimize cavities, one of the most critical parts of an accelerator.

A research team led by the Department of Energy’s Oak Ridge National Laboratory has bridged a knowledge gap in atomic-scale heat motion. This new understanding holds promise for enhancing materials to advance an emerging technology called solid-state cooling.

An environmentally friendly innovation, solid-state cooling could efficiently chill many things in daily life from food to vehicles to electronics — without traditional refrigerant liquids and gases or moving parts. The system would operate via a quiet, compact and lightweight system that allows precise temperature control.

Although the discovery of improved materials and the invention of higher-quality devices are already helping to promote the growth of the new cooling method, a deeper understanding of material enhancements is essential. The research team used a suite of neutron-scattering instruments to examine at the atomic scale a material that scientists consider to be an optimal candidate for use in solid-state cooling.
