A FeN4─O/Clu@NC‐0.1Ac catalyst containing atomically‐dispersed FeN4─O sites (medium‐spin Fe2+) and Fe clusters delivered a half‐wave potential of 0.89 V for ORR and an overpotential of 330 mV at 10 mA cm−2 for OER in 0.1 m KOH. When the catalyst was used in a rechargeable Zn–air battery, a power density of 284.5 mW cm−2 was achieved with excellent ...

Comparative Study Of Conventional Slab, Flat Slab And Grid Slab Using ETABS
Abstract In today’s construction, the traditional slab is mostly supported by a beam, with a small slab thickness and a large beam depth, and the weight is carried from beam to column. The flat slab allows architects to place partition walls wherever they are needed. It is widely used because it reduces weight, speeds up building, and is

Lead halide perovskite nanocrystals are promising scintillators but suffer from reabsorption losses and limited compatibility with high‐Z additives. Hybridization of CsPbBr3 nanocrystals with PbBr2‐passivated HfO2 nanoparticle sensitizers, achieved during or after synthesis, produces stable composites with maintained optical quality, improved ...

Analysis of Post-Tensioned Flat Slabs, Conventional Slabs, and Flat Slabs using Etabs Software
Abstract: The modern-day submit-tensioning method is especially well-known because of its practicality; so, we will design the maximum safe and economical construction using this method. Every time we are planning the application of this technique, we must include more protective measures for slabs' shear and deflection criteria.

Contact Lens with Moiré Patterns for High‐Precision Eye Tracking
This work presents a passive contact lens for high‐precision eye tracking, integrating a microscopic moiré grating label. The parallax‐induced shift of macroscopic moiré patterns enables angle measurement with 0.28° precision using a standard camera under ambient light.

Effect of hybrid steel-polypropylene fiber on punching shear behavior of flat slab with an opening
This research aimed to gain a better understanding of how the addition of fiber influences the punching shear capacity of two-way slabs by conducting an experiment into the structural behavior of flat slabs with and without a square opening using ...

Rational halogen mixing strategy was employed to shift the bandgap of Cs2PbBr2I2 from ultraviolet to visible region, enabling first realization of a visible‐light photodetector with this 2D layered Ruddlesden‐Popper perovskite material. Under illumination, light‐induced internal field forms and drives trap‐mediated persistent photoconductivity ...

Self‐Refreshing Bi‐Based Active Sites for Efficient and Durable Electrochemical CO2 Reduction
A self‐refreshing Bi‐based catalyst is developed through the fabrication of a novel basic bismuth nitrate pre‐catalyst, which exhibits differential active sites of Bi2O2CO3 at low potentials and metallic Bi phases at high potentials, self‐repairing capability, and thus wide‐potential‐window efficiency and ultralong durability toward electrochemical CO2
