Halide Perovskite Photocatalysts for Clean Fuel Production and Organic Synthesis: Opportunities and Challenges

open access: yesAdvanced Materials, EarlyView.
This review provides the state‐of‐the‐art overview of halide perovskite‐based photocatalysts for hydrogen production from water and halogen acid solutions, CO2 reduction into value‐added chemicals, and organic chemical transformations. Different types of halide perovskite photocatalysts and their relative efficiencies for hydrogen generation and CO2 ...

Colisão com o 'efeito estilingue'

open access: yesRevista Brasileira de Ensino de Física
Abordamos teoricamente a colisão com o 'efeito estilingue' onde um corpo transfere momento linear e energia cinética para um segundo corpo de massa menor, fazendo com que a energia mecânica desse segundo corpo cresça de forma surpreendente. Mostramos que,

Controlled Formation of Skyrmion Bags

open access: yesAdvanced Materials, EarlyView.
This work demonstrates stabilization of complex magnetic skyrmion bags in ferromagnetic thin films through precisely engineered anisotropy defects using ion irradiation. The researchers achieve controlled field‐ and laser‐induced generation of skyrmionia, target skyrmions, and higher‐order skyrmion bags at room temperature. This reliable platform opens

Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics

open access: yesAdvanced Materials, EarlyView.
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent

“Safe Struck Ship”(3S):Software Package for Structural analysis of collision between ships [PDF]

open access: yesPort Said Engineering Research Journal, 2012
Each year, thousands of tons of crude oil and petroleum products are spilled in the seas as a result of collision between ships. So, as a part of the overall effort to promote maritime safety and environmental protection an integrated software package of

Stretchable, Multiplexed, and Bimodal Sensing Electronic Armor for Colonoscopic Continuum Robot Enhanced by Triboelectric Artificial Synapse

open access: yesAdvanced Materials, EarlyView.
Colonoscopic continuum robots lack sensing, endangering intestinal tissue. An ideal sensing array is hard to integrate. This work introduces a 3D crosslinked stretchable E‐armor with full‐coverage and multiplexing. It has bimodal sensing, forms a triboelectric synapse, uses CNN‐LSTM, and has a hydrogel and innovative triboelectric materials.
