World's first observation of magnetic fields of individual lattice planes achieved using Hitachi's atomic-resolution holography electron microscope

Tokyo, July 4, 2024 --- Hitachi, Ltd. (TSE: 6501, Hitachi), Kyushu University, RIKEN, and HREM Research Inc. (HREM) today announced the world's first observation of magnetic fields of individual lattice planes.*1 This was achieved by using Hitachi's atomic-resolution holography electron microscope and a method enabling magnetic field observation of samples with uneven structures and compositions (hereinafter referred to as non-uniform samples)*2 such as magnetic multilayer films, which have been difficult to observe so far, in collaboration with National Institute of Advanced Industrial Science and Technology (AIST) and National Institute for Materials Science (NIMS). Observation was accomplished by developing a technology with a higher degree of electron-holography precision and automated post-image-capture focus correction. With this, it is now possible to observe magnetic fields of the atomic-layer level at local boundaries between materials (interfaces), which greatly affe

Calls for funding the arts and humanities in R.I. should be more focused and inclusive

Here’s a strategy unlikely to succeed: “We need this money and don’t much care where it comes from.” And yet it was employed by supporters of two bills to fund arts and cultural organizations in Rhode Island in our state Legislature this spring. Each bill authorized $18 million to be distributed to 14 identified organizations, including the Rhode Island State Council for the Arts, which would redistribute some of the money through a grants program. The bills suggested the money could come from an allocation of ARPA (COVID relief) funds, or a bond, or a budgeted appropriation. In spite of a lobbying effort, the proposed legislation did not even make it out of committee in either the House or the Senate. Instead, the House approved budget includes an authorization for a bond to be put before the voters to borrow $10 million for a shorter list of organizations (four, to be exact) for capital expenditures only. We tend to pass bonds in this state pretty readily, so the arts and culture o

Understanding trade data quality with the Discrepancy Index

Image
This blog is part of a series about WITS, the World Integrated Trade Solution, a collaborative trade data platform developed by the World Bank and other institutions. This is the eighth installment of the series—for further reading, here are the first, second, third, fourth, fifth, sixth and seventh installments. Accurate trade data is essential for understanding global trade patterns, making informed policy decisions, and conducting empirical research. However, discrepancies in trade reporting can arise due to various factors, including logistical issues and deliberate misclassification. These discrepancies can lead to distortions in key trade metrics and negatively impact research findings. How to measure these discrepancies? The Discrepancy Index (DI) is a valuable tool for assessing the quality of trade data. By examining discrepancies in reported trade values, the DI provides insights into the accuracy and reliability of trade data, ultimately contributing to better-informed trad

KRISS successfully develops domestic 6G antenna measurement system

Improves usability with a portable design and evaluates 6G antenna performance with distortion-free non-metallic sensors. Technology transfer to domestic company completed, accelerating 6G commercialization. # In April 2019, South Korea ambitiously launched the world's first 5G mobile communication service. While 5G in the 3.5 GHz band was commercialized, the communication quality did not meet consumer expectations. The installation of base stations in the 28 GHz band, which would provide true 5G service, was slow due to profitability concerns. Consequently, the government reclaimed the frequency bands from all three major telecommunications companies last year. As countries around the world prepare for the 6G era, it is time to reflect on the disappointing experiences of 5G commercialization and focus on building the 6G infrastructure. Korea Research Institute of Standards and Science (KRISS) succeeded in developing domestically produced equipment to evaluate the performance of 6

IISc Develops 3D Hydrogel to Study TB Research

Bengaluru: In an advancement for tuberculosis research, scientists at Indian Institute of Science created a novel 3D hydrogel culture system that closely mimics the human lung. This provides a platform to track and study how tuberculosis bacteria infect lung cells and test the efficacy of therapeutics used to treat the infection. Mycobacterium tuberculosis (Mtb) is a dangerous pathogen.In 2022, it affected 10.6 million people and caused 1.3 million deaths, according to World Health Organisation. Led by Rachit Agarwal, associate professor at the department of bioengineering, the IISc team addressed limitations of traditional 2D culture models. These older models fail to replicate the complex 3D structure of lung tissue, potentially skewing research results. “It is a very old bug, and it has evolved with us quite a bit,” said Agarwal, who’s a corresponding author of the study, published in Advanced Healthcare Materials. The new hydrogel culture is composed of collagen, a key component of

Drawn-Out Heat Wave Expected to Finally Let Up in Many Parts of the U.S.

The forecast is welcome news for many East Coasters, who faced stifling conditions over the weekend. But the Southeast and Southern Plains are expected to continue to scorch this week. The unusually early heat wave that shattered temperature records across the Northeast, Mid-Atlantic States and Midwest last week is expected to subside by Monday, bringing relief to tens of millions of Americans. The National Weather Service forecast lower temperatures for much of the Mid-Atlantic on Monday. In Washington, the heat index — a measure of how conditions feel, with humidity taken into consideration — is expected to reach a high of 87 degrees, down from 102 on Sunday. Philadelphia is also expected to have a much lower heat index value, at 82 degrees, down from 104 on Sunday, forecasters say. And in Trenton, N.J. — the capital of the state, which climate experts say is warming faster than others in the region — the figure is expected to come down to 82, from 103 on Sunday. The forecast is wel
