Hexagonal B–C–N composite consisting of h-BN and graphite separated by B–C nanolayer [PDF]

open access: yesMatter and Radiation at Extremes
Graphite and hexagonal boron nitride (h-BN), despite their structural similarity, exhibit opposing electronic properties, namely, metallic conductivity and wide-bandgap insulation, respectively.

Pressure alopecia

open access: yesInternational Journal of Trichology, 2012
Postoperative or pressure alopecia (PA) is an infrequently reported group of scarring and non-scarring alopecias. It has been reported after immobilization of the head during surgery and following prolonged stays on intensive care units, and may be analogous to a healed pressure ulcer. This review presents a summary of cases published in pediatrics and

Some Magnetic Properties and Magnetocaloric Effects in the High-Temperature Antiferromagnet YbCoC2

open access: yesMagnetochemistry, 2023
The YbCoC2 compound, which crystallizes in a base-centered orthorhombic unit cell in the Amm2 space group CeNiC2 structure, is unique among Yb-based compounds due to the highest magnetic ordering temperature of TN=27 K.

Phase transition mechanism and bandgap engineering of Sb2S3 at gigapascal pressures

open access: yesCommunications Chemistry, 2021
Antimonite (Sb2S3) has potential applications for solar energy, but how its layered structure changes under pressure is incompletely understood. Here diamond anvil cell experiments supported by first principles calculations offer a structural explanation

Sustained Therapeutic Efficacy of Intravenous Plasminogen Concentrate in Pediatric Patients With Type 1 Plasminogen Deficiency: An Analysis of Dosing Parameters and Clinical Outcomes

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Type 1 plasminogen deficiency (PLGD‐1) is an ultra‐rare autosomal recessive disorder caused by variants in the PLG gene and affects approximately 1.6 individuals per million. The condition is characterized by decreased plasminogen levels and impaired function, resulting in fibrin‐rich lesions on mucous membranes throughout the body.

Everything you always wanted to know about metallic hydrogen but were afraid to ask

open access: yesMatter and Radiation at Extremes, 2020
The hydrogen molecule is made from the first and lightest element in the periodic table. When hydrogen gas is either compressed or cooled, it forms the simplest molecular solid. This solid exhibits many interesting and fundamental physical phenomena.
