Upscaling the Fabrication of Rod‐Shaped Microgels: A Microfluidic Method Combining Step‐Emulsification With Consecutive Droplet Confinement in Parallelized Microchannels

Advanced Materials, EarlyView.
A microfluidic method is presented which enables parallelized fabrication of rod‐shaped microgels, based on step‐emulsification (SE) droplet generation and subsequent droplet distribution and confinement, combined in a single device. Microgel rods are fabricated in parallel at different flow rates based on two light‐mediated crosslinking chemistries ...

Atom–Cluster Synergy in Scalable Fe–Ru Dual‐Site Architectures Accelerates Alkaline Hydrogen Evolution

Advanced Materials, EarlyView.
A mechanochemically synthesized dual‐site electrocatalyst (RuNC@Fe1NC) accelerates alkaline hydrogen evolution via atomic‐level spatial decoupling. Oxophilic Fe single atoms effectively dissociate water, while adjacent Ru nanoclusters rapidly recombine hydrogen.

Effect of reinforcement corrosion on punching shear of RC flat slabs incorporating steel and synthetic fibers

Case Studies in Construction Materials
Reinforcement corrosion weakens the punching shear capacity of RC flat slabs. This study tested twelve large-scale slabs (1500 × 1500 × 100 mm) with hooked-end steel or macro-synthetic fibers (0.5–1.0 % by volume) and control samples.

Prediction of punching shear capacities of two-way concrete slabs reinforced with FRP bars

HBRC Journal, 2013
Where corrosion of steel reinforcement is a concern, fiber-reinforced polymer (FRP) reinforcing bar or grid reinforcement provides an alternative reinforcement for concrete flat slabs.

In Situ Lithium Nitridosilicate Interlayer via Reactive Anolyte Design for All‐Solid‐State Silicon Anodes

Advanced Materials, EarlyView.
Interfacial reactions in all‐solid‐state batteries are conventionally suppressed; here, they are designed. Vacancy‐rich β‐Li3N, acting as an anolyte, reacts controllably with silicon during composite anode fabrication, building a purpose‐made lithium nitridosilicate interlayer on every particle surface.

Analysis of instability of tall buildings with prestressed and waffle slabs

Revista IBRACON de Estruturas e Materiais
The construction system of prestressed flat slabs has been gaining market in Brazil, since it eliminates the use of beams, allows you to perform structures under coluns by area and reduces the cycle of concrete slabs.
