Advanced Materials, EarlyView.A gradient electron energy level strategy is constructed to reduce voltage losses in planar HTL‐free CsPbI2Br C‐PSCs. This electron extraction optimization enables rapid photogenerated electron extraction and carrier separation, thereby suppressing recombination at the back contact. The resulting PSCs deliver a record VOC of 1.41 V, a high PCE of 17.42%

Connecting Droplet Adhesion with Sperm Kinematics: A New Paradigm in Sperm Quality Monitoring
Advanced Materials Interfaces, EarlyView.This study demonstrates direct experimental evidence to establish a nonintuitive connection between the motion characteristics of self‐propelled sperm cells and their surface interaction. Simultaneous motion visualization and cantilever‐deflection‐based adhesion characterization reveal that sperm‐cell droplets with higher motility exhibit lower surface

Advanced Materials Interfaces, EarlyView.The study presents an easily adaptable approach for manufacturing electrodes with boron‐doped silicon supporting iridium nanoparticles for oxygen evolution in acidic electrolysis. Colloidal Ir nanoparticles are deposited onto B‐doped Si and sprayed onto titanium substrates, achieving ultralow Ir loading while enhancing conductivity and electrochemical ...

Feasibility of Mars aircraft. Aerodynamics in Mars atmosphere.
, 2018 Mars tenuous atmosphere imposes very hard restrictions on aircraft. However, several designs have been proposed. The goals of this challenging work are:-To identify a realistic design that can fly in Mars with the technology currently available.-Perform aerodynamic simulations of the main elements of the design selected, using state of the art CFD ...

Advanced Materials Interfaces, EarlyView.The prepared ceramic membrane exhibited 28.84 µm average pore size and hydrophilic properties (≈27.4° contact angle). FTIR shows the presence of aluminol, siloxane, and hydroxyl groups and XRD confirms the presence of quartz and kaolinite phases. Separation of natural organic matter from drinking water is achieved by microfiltration at 0.25 bar and is ...
