Band Gap Tuneability in Antiperovskite‐Based Nitrides AE3PnN and Imides AE5Pn2(NH)2 (AE = Ca, Sr; Pn = As, Sb, Bi)

Angewandte Chemie, EarlyView.
A series of imide‐based defect antiperovskites AE5Pn2(NH)2 (AE = Ca, Sr; Pn = As, Sb, Bi) has been synthesized using the ammonothermal method. DFT calculations and spectroscopy revealed direct band gaps suitable for photovoltaic absorber materials. The discovered compounds can further be used as precursors for the synthesis of AE3PnN antiperovskites as

Expression cloning of SR-BI, a CD36-related class B scavenger receptor.

Journal of Biological Chemistry, 1994
Scavenger receptors are integral membrane proteins that mediate the endocytosis of modified lipoproteins. The first of these to be purified and cloned were the type I and II macrophage scavenger receptors (SR-AI and SR-AII; class A scavenger receptors ...

Temperature‐Driven Emission Redistribution of Yb2+ in SrB4O7 Enables Highly Sensitive Optical Thermometry Supported by Multiple Linear Regression

Advanced Science, EarlyView.
A novel optical thermometer exploits the rare UV emission of Yb2+ ions in a SrB4O7 host, enabling highly sensitive, non‐contact temperature measurements from 80 to 420 K. The applied multiple linear regression (MLR) analysis results in a multiple increase in the resulting temperature sensitivity.

Bi_2Sr_2CuO_y Thin Film Prepared by Separated Evaporation/Oxidation/Crystallization Technique with Molecular Beam Epitaxy [PDF]

, 1994
Thin films of Bi_2Sr_2CuO_y were grown with MBE (Molecular Beam Epitaxy) by the separated evaporation/oxidation/crystallization technique on MgO (100) substrate. This is the unit-byunit process consisting of three steps: metal layers deposition of (Bi-Sr-

Dual‐Sabatier Optima: How Reaction Mechanism Determines Activity Volcano Map of Dual‐Atom Catalysts for Oxygen Reduction Reaction

Angewandte Chemie, EarlyView.
Dual‐atom catalysts (DACs) for oxygen reduction reaction (ORR), where the dissociative mechanism dominates, show a dual‐Sabatier optima volcano map, diverging from the classical single‐peak volcano of the associative mechanism. Potential‐dependent microkinetic modeling and interpretable machine learning rationalize experimental data and provide design ...

Apolipoprotein A-I conformation markedly influences HDL interaction with scavenger receptor BI

Journal of Lipid Research, 2001
Apolipoprotein A-I (apoA-I) is an important ligand for the high density lipoprotein (HDL) scavenger receptor class B type I (SR-BI). SR-BI binds both free and lipoprotein-associated apoA-I, but the effects of particle size, composition, and ...

Asymmetric Electrostrain/Electrobending in Piezoelectric Ceramics: Role of Defect Dipoles or Oxygen Vacancies

Advanced Science, EarlyView.
Defect‐configurational origins of the asymmetric apparent electrostrain are revealed in different piezoelectric ceramics via atomic‐scale visualization of defect configurations. Migration of oxygen vacancies leads to the electrobending effect in N2‐sintered BaTiO3, while defect dipoles in Ba0.99TiO2.99 generate true asymmetric electrostrain without ...

ApoB-containing lipoproteins in apoE-deficient mice are not metabolized by the class B scavenger receptor BI

Journal of Lipid Research, 2004
The scavenger receptor class B type I (SR-BI) recognizes a broad variety of lipoprotein ligands, including HDL, LDL, and oxidized LDL. In this study, we investigated whether SR-BI plays a role in the metabolism of cholesterol-rich lipoprotein remnants ...

Implications of Transient Negative Capacitance Effect in Ferroelectric Polarization Dynamics

Advanced Electronic Materials, EarlyView.
Transient voltage artifacts observed during ferroelectric switching are shown to originate from measurement circuitry rather than intrinsic negative capacitance. By correlating switching current, time scale, and series resistance, this work establishes practical design rules for reliable pulse‐switching experiments and circuit integration of ...

SR-BI is required for microvillar channel formation and the localization of HDL particles to the surface of adrenocortical cells in vivo

Journal of Lipid Research, 2002
Scavenger receptor class B type I (SR-BI) mediates the selective uptake of HDL cholesteryl ester into liver and steroidogenic tissues. In steroidogenic cells, juxtaposed microvilli, or microvilli snuggled against the plasma membrane create microvillar ...
