A Computational Approach for Biomimetic Design of Liver‐On‐A‐Chip

Advanced Intelligent Discovery, EarlyView.
A biomimetic liver‐on‐a‐chip with antiparallel perfusion was designed using COMSOL‐guided simulation to replicate hepatic acinus transport. Full‐scale modelling revealed diffusion‐dominated, length‐dependent nutrient gradients and low‐shear conditions.

Punching shear of RC slabs exposed to fire: assessment of load-bearing capacity based on European and American provisions. Part 1 – General code requirements [PDF]

Archives of Civil Engineering
Slab-column connection is one of the most critical points in reinforced concrete structures. Punching shear capacity of this connection must be properly determined in both the persistent design situation and the accidental design situation of fire ...

Assessment of shear reinforcement enhancement on the punching shear capacity of flat concrete slabs with openings

Structural Concrete
AbstractReinforced concrete flat slabs are widely employed in contemporary architecture due to their structural efficiency and construction simplicity; however, their susceptibility to punching shear failure remains a critical design concern, particularly at slab–column connections where concentrated loads occur. This brittle failure mechanism is a key

Beyond wound sealing: A dual‐functional adhesive nanofiber membrane promoting coagulation and osteogenesis in extraction sites

BMEMat, EarlyView.
Inspired by the suction mechanics of octopus suckers, a dual‐layer nanofiber membrane integrates antibacterial protection, strong wet adhesion, and osteogenic support, offering a bioinspired strategy for effective hemostasis and alveolar bone preservation.

Numerical modelling of the punching behaviour of steel fibre reinforced self-compacting concrete flat slabs [PDF]

, 2013
Punching shear failure on flat reinforced concrete slabs of residential and commercial buildings is generally avoided by using transversal reinforcement and/or chapiters.

Review and prospects of shear test of bolted rock joints

Deep Underground Science and Engineering, EarlyView.
The laboratory shear test equipment, test method, and numerical simulation of bolted rock joints were summarized. The shortcomings and limitations of the current research were analyzed, and the research prospects were proposed. Abstract Rock bolting is a critical approach in geotechnical engineering for supporting weak rocks.

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.

Analysis and Optimization of Early‐Warning Indicators for Impact Critical Stress in Deep Soft Coal Seams

Energy Science &Engineering, EarlyView.
This study determines the impact critical stress early‐warning indicators for deep soft coal seams: 18 MPa (shallow holes), 20 MPa (deep holes), and 3 MPa/d daily stress change rate, via theoretical, experimental and simulation methods. ABSTRACT The accurate determination of early‐warning indicators for critical impact stress in deep soft coal seams is

Valorizing lemon pomace in bread: Consumer acceptance of fermented and pre‐gelatinized Cardaba banana flour formulations

Food Biomacromolecules, EarlyView.
Abstract Whereas gluten‐free bread production often relies on starch‐heavy formulations, this study introduces a novel approach by leveraging the synergistic effects of fermented/pre‐gelatinized Cardaba banana, pigeon pea, and lemon pomace—an underutilized agro‐industrial byproduct.
