An Adaptive Neuro-Fuzzy Inference Model to Predict Punching Shear Strength of Flat Concrete Slabs

Applied Sciences, 2019
An adaptive neuro-fuzzy inference system (ANFIS)-based model was developed to predict the punching shear strength of flat concrete slabs without shear reinforcement. The model was developed using a database collected from 207 experiments available in the

Hierarchical Twin Networks Enable Exceptional Strength and Fracture Toughness in Titanium

Advanced Science, EarlyView.
A commercial‐purity titanium with hierarchical ultrafine twin structures delivers an exceptional combination of fracture toughness (KJIc) of 187 MPa·m1/2 and specific yield strength of 140 MPa·cm3·g−1, in which pre‐engineered high‐density twin boundaries stimulate massive and dislocations to blunt crack tip.

Synergistic Stabilization of Potassium Metal Anodes Through Orange‐Peel Elimination and Robust Solid–Electrolyte Interphase Formation

Advanced Science, EarlyView.
Synergistic control of surface uniformity and solid–electrolyte interphase robustness regulates potassium deposition, suppressing dendritic growth and enabling uniform, dense potassium plating. This combined strategy promotes stable interfacial chemistry and homogeneous electric‐field distribution, leading to enhanced reversibility and long‐term ...

Microblasting Wound Dressings Mechanically Disrupt Polymicrobial Biofilms to Enhance Healing in Treatment‐Resistant Wounds

Advanced Science, EarlyView.
Treatment‐resistant wounds caused by polymicrobial biofilms are refractory to conventional therapies due to the dense extracellular matrices. We developed μBLAST, a microblasting wound dressing that combines MnO2‐doped biosilica and a H2O2‐releasing mesh to generate localized oxygen microbubbles that mechanically disrupt biofilms.

Revealing the Ion Regulation Effect of Zwitterionic All‐Solid‐State Electrolytes in Lithium Metal Batteries

Advanced Science, EarlyView.
This study investigates zwitterionic all‐solid‐state electrolytes, demonstrating strong carboxyl‐Li+ interaction that forms “ion‐enrichment pathway”‐like domains and manipulates Li+ deposition. Additionally, surface‐enriched zwitterions generate a dual‐layer SEI with an inner Li2O‐rich and outer LiF‐rich structure. Through ionic flux regulation and SEI

Effect of mid-thickness rebar mesh on the behavior and punching shear strength of interior slab–column connection

HBRC Journal, 2016
Punching shear failure is a major problem encountered in the design of reinforced concrete flat plates. The utilization of shear reinforcement via shear studs or other means has become a choice for improving the punching shear capacity.

Punching Shear Responses of Flat-Plate Assemblages Strengthened with Engineered Cementitious Composites

International Journal of Concrete Structures and Materials
Flat plate flooring systems are susceptible to punching shear failures at slab-column joints, which is pointed out as one of critical obstacles in its application to high-rise buildings in strong wind or seismic regions.

Behavior of composite pre-flat slabs in resisting punching shear forces

Alexandria Engineering Journal, 2020
Due to large use of the composite pre-flat slabs “two layers slabs” especially manifested in pre-cast system slabs such as frequently used in bridge dicks, large thickness slabs casted on two layers or change usage of existing structure.

Enhancing All‐Solid‐State Batteries Performance Through Thickness Control and Surface Passivation of Thermally Evaporated Lithium Metal Anodes

Advanced Science, EarlyView.
This study demonstrates that thermally evaporated lithium anodes combined with LiF passivation provide a high‐performance thin anode design for next‐generation ASSBs. This approach increases the critical current density from 1.6 to 2.6 mA cm−2, enabling full cells to achieve over 500 and 300 cycles at 1.5 and 3 mA cm−2, respectively, outperforming even
