Cooperative torus mode emission of O-ring lasers

AIP Advances, 2020
Deformable ring lasers were fabricated by dispersing fluorescent dye (rhodamine 6G) in silicone rubber rings, i.e., the so-called O-rings. When excited with a pulsed green laser, an O-ring of 750 µm diameter exhibited a stimulated emission with a ...

3D‐Printed Porous Hydroxyapatite Formed via Enzymatic Mineralization

Advanced Functional Materials, EarlyView.
Bone combines lightness, strength, and the ability to heal, inspiring new materials design. This work introduces a room‐temperature, enzyme‐mediated 3D printing method to create porous hydroxyapatite scaffolds. The process avoids energy‐intensive sintering, preserves bioactivity, and allows control over porosity and mineralization.

Ground-based optical transmission spectrum of the hot Jupiter HAT-P-1b

, 2019
Time-series spectrophotometric studies of exoplanets during transit using ground-based facilities are a promising approach to characterize their atmospheric compositions. We aim to investigate the transit spectrum of the hot Jupiter HAT-P-1b.

A New Threshold Switching Device With Tunable Negative Differential Resistance Based on ErMnO3 Polymorphs

Advanced Functional Materials, EarlyView.
Polymorph engineering in ErMnO3 enables low‐voltage, forming‐free threshold switching with tunable negative differential resistance. Conducting orthorhombic regions embedded in an insulating hexagonal matrix provide controlled Joule‐heating‐enhanced Poole–Frenkel transport. The hexagonal phase prevents excessive heating and breakdown.

Liver transplantation across ABO blood groups [PDF]

, 1986
Six hundred seventy-one first, second, and third orthotopic liver allografts in 520 patients were reviewed to determine the effect of donor-recipient mismatches or incompatibility for the ABO blood group on graft survival. A significant advantage for ABO

Nanodiamond‐Based Quantum Sensing Reveals Changes in Endo‐Lysosomal Activity of Stimulated Cardiac Fibroblasts in a Cellular Fibrosis Model

Advanced Functional Materials, EarlyView.
Quantum sensing reveals intricate patterns linking endo‐lysosomal maturation to cardiac fibrosis progression, highlighting complexity in cellular remodeling. This study investigates fibroblast‐to‐myofibroblast transition under cell aging, stiffness, and TGF‐β stimulation, comparing nanodiamond uptake, endo‐lysosomal dynamics, and free radical ...
