Potential of Psidium guajava Leaf as Natural UV Filter in Topical Sunscreen Emulsion

Journal of Applied Science and Engineering
This study aims to develop a sunscreen formulation using guava (Psidium guajava) leaf extract (GLE), obtained via ethanol-water (4:1 v/v) extraction. The crude extract was greenish-brown solid with a percentage yield of 19.88 ± 0.28.

Beyond Earth: Resilience of Quasi‐2D Perovskite Solar Cells in Space

Advanced Materials, EarlyView.
In the article (DOI: 10.1002/adma.202520433), Christoph Putz and co‐workers demonstrate rigid quasi‐2D perovskite solar cells operating in low Earth orbit, delivering stable power for more than 100 days under real‐space conditions. In‐orbit performance is correlated with extensive ground‐based thermal and proton‐irradiation studies on rigid and ...

Transparent Perovskite Light‐Emitting Diodes with Conductive Oxide Top Electrodes

Advanced Materials, EarlyView.
Transparent perovskite light‐emitting diodes (TrPeLEDs) enable simultaneous display and transparency, expanding application possibilities. Using a metal oxide buffer layer and pulsed laser deposition, TrPeLEDs with diverse compositions and architectures are demonstrated.

Patterning of Lead Halide Perovskite Device Stacks on CMOS Readout Using Selective Microfabrication Protocols

Advanced Materials, EarlyView.
We present a microfabrication and integration strategy for lead halide perovskite photodetectors on electronic readouts. Standard photolithography, aqueous processing, selective transparent electrode etching, and plasma‐assisted pixel isolation enable precise monolithic integration of patterned 400 × 400 perovskite microphotodetector arrays on a CMOS ...

High‐Mobility and Low‐Voltage Top‐Gate Transistors Comprising an InSnO–InSnWO Channel Layer and a Polymethyl Methacrylate Dielectric Layer

Advanced Materials Interfaces, EarlyView.
The top‐gate thin film transistors (TFTs) combining the advantages of both the inorganic InSnWO channel layer and the organic polymethyl methacrylate dielectric layer were prepared. The optimized TFTs exhibit excellent performance, including a high mobility (> 60 cm2 V−1 s−1), a low threshold voltage (< 0.50 V; positive value), and robust stabilities ...

NIR‐Activated Ag2S Quantum Dots for Efficient Broad‐Spectrum Antibacterial and Biofilm Disruption

Advanced Materials Interfaces, EarlyView.
This study presents a novel non‐antibiotic strategy leveraging NIR‐activated Ag2S QDs for synergistic PTT/PDT. The platform degrades the protective extracellular matrix via localized hyperthermia, facilitating deep penetration and ROS‐induced oxidative damage.
