Abstract The 2019 coronavirus disease (COVID‐19) pandemic has seriously impacted the performance of all types of businesses. It has given a tremendous structural boost to e‐commerce enterprises by forcing customers to online shopping over visiting physical stores. Moreover, customer expectations of the digital and operational capabilities of e‐commerce

Optimized Pt–Co/BN Catalysts for Efficient NaBH4 Hydrolysis
The BOx shell protects bimetallic Pt–Co catalyst, where the BOx shell modulates the electronic properties of the Co–Pt active sites and the core–shell structure effectively prevents metal leaching, efficiently and stably produces hydrogen through sodium borohydride hydrolysis reaction.

Al‐Doped LaTiO2N Prepared via Flame Spray Pyrolysis for Photocatalytic Hydrogen Evolution
Flame spray pyrolysis enables the synthesis of La–Ti oxides with a simple perovskite‐type structure, and Al doping promotes the formation of the simple perovskite‐type La–Ti oxides. The Al‐doped LaTiO2N obtained by nitridation has a reduced defect concentration due to suppressed structural change, which contributes to the improvement of hydrogen ...

Recycling lithium‐ion batteries by smelting leads to lithium loss in the slag. Industrial battery slag is analyzed using chemical and mineralogical methods, revealing a complex composition with a consistent lithium content of 0.82%. Lithium is primarily found in β‐eucryptite, which contains 5.51% lithium.

Influence of aggregate size and fraction on shrinkage induced micro-cracking of mortar and concrete
In this paper, the influence of aggregate size and volume fraction on shrinkage induced micro-cracking and permeability of concrete and mortar was investigated. Nonlinear finite element analyses of model concrete and mortar specimens were performed.

Z‐schematic water splitting under visible light irradiation using TaON as an O2‐evolving photocatalyst, (CuGa)0.5ZnS2 as a H2‐evolving photocatalyst, and reduced graphene oxide as an electron mediator is achieved. This combination of a metal oxynitride and a metal sulfide photocatalysts is new for a Z‐scheme system for water splitting under visible ...
