First-principles study of hydrogen adsorption behavior in C15 Laves phase compound ZrV2

open access: yesAIP Advances, 2021
The hydrogen absorption behavior of C15 Laves phase compounds ZrV2 has been systematically investigated by the first-principles calculations. In the C15 Laves phase, hydrogen atoms can occupy three possible tetrahedral interstitial positions—2A2B, 1A3B ...

High‐Resolution MRI Revealed Different Etiology‐Specific Associations With Cerebral Infarction in Adult Moyamoya Vasculopathy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective High‐resolution MRI enables detailed assessment of intracranial vessel wall pathology in moyamoya vasculopathy. We aimed to classify adult moyamoya vasculopathy etiologies using high‐resolution MRI and to examine subtype‐specific associations between high‐resolution MRI features and ischemic infarction.

The H 0 tension in light of vacuum dynamics in the universe [PDF]

open access: yes, 2017
Despite the outstanding achievements of modern cosmology, the classical dispute on the precise value of H 0 , which is the first ever parameter of modern cosmology and one of the prime parameters in the field, still goes on and on after over half a ...

Design of pressure-sensing diaphragm for MEMS capacitance diaphragm gauge considering size effect

open access: yesAIP Advances, 2018
MEMS capacitance diaphragm gauge with a full range of (1∼1000) Pa is considered for its wide application prospect. The design of pressure-sensing diaphragm is the key to achieve balanced performance for this kind of gauges.

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...
