Wafer‐Scale Top‐Down Patterning of Metal Halide Perovskites

open access: yesAdvanced Materials Technologies, EarlyView.
Wafer‐scale patterning of metal halide perovskite films is demonstrated on 150 mm substrates using a chemically amplified resist, polymethyl methacrylate (CAR‐PMMA) and a single reactive ion etching step. The streamlined process preserves film luminescence while defining submicrometer features across the full wafer, enabling dense, scalable integration

2,3-erythro-Dihydroxyhexacosanoic acid and homologs: isolation from yeast cerebrin phosphate and determination of their structures

open access: yesJournal of Lipid Research, 1973
Homologs of methyl esters of very polar fatty acids were obtained by methanolysis of cerebrin phosphate isolated from baker's yeast. The major ester component was isolated by preparative gas–liquid chromatography and was found to be 2,3 ...

Low‐Outgassing Liquid Metal–Silicone Composites for Multifunctional Space Applications

open access: yesAdvanced Materials Technologies, EarlyView.
Integrating liquid metal microdroplets into a space‐grade silicone creates a multifunctional composite while preserving its inherent flexibility and low‐outgassing behavior. The composite has 11×$\times$ higher thermal conductivity while remaining thermally stable and maintaining a total mass loss of ≤$\le$ 1% under thermal vacuum testing.

Endotoxin in the occupational environment of bakers: method of detection.

open access: yesInternational journal of occupational medicine and environmental health, 1995
The present study was conducted in a large mechanical city bakery. The AS-50 aspirators equipped with cellulose membrane filters were used for dust sampling. Airborne microbial content was assessed by means of sedimentation and aspiration using an Andersen sampler on Petri plates containing McConkey's medium.

Parameter Investigation for Stamp Manufacturing of Complex 3D Geometries Using Nanoimprint Lithography

open access: yesAdvanced Materials Technologies, EarlyView.
Nanoimprint lithography can replicate complex 3D microstructures with undercuts using single‐layer polymer stamps of different elasticities. By combining experiments and simulations, T‐shaped geometries and suitable undercut radii were identified that minimize stress and defects during demolding.

Strong Enhancement of Er3+ Emission at Room Temperature in Si3N4 Metasurfaces

open access: yesAdvanced Optical Materials, EarlyView.
Erbium‐doped SiN metasurfaces are engineered to support Mie resonances at 1.55μm$1.55\text{}\mathrm{\mu}\mathrm{m}$, enhancing the local density of optical states and accelerating spontaneous emission. By optimizing nanocylinder radius and implantation depth, room‐temperature PL is increased about 18‐fold, while lifetime shortens by nearly an order of ...

Identification of the Subcompartment-Specific Mitochondrial Proteome by APEX2 Proximity Labeling in Saccharomyces cerevisiae

open access: yesBio-Protocol
The cellular compartments of eukaryotic cells are defined by their specific protein compositions. Different strategies are used for the identification of the subcellular proteomes, such as fractionation by differential centrifugation of cellular extracts.

Residual Tetramethylammonium Hydroxide Limits ZnO Nanoparticle‐Based Quantum Dot Light‐Emitting Diode Performance

open access: yesAdvanced Optical Materials, EarlyView.
Residual tetramethylammonium hydroxide (TMAH) from ZnO nanoparticle (NP) synthesis is uncovered as a hidden impurity that migrates into quantum dot emissive layers during thermal processing. The resulting exciton quenching reduces the efficiency of quantum dot light‐emitting diodes despite improved electron transport upon annealing.
