Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

The predictive performance of design models for the punching resistance of SFRC slabs in inner column loading conditions [PDF]

, 2012
In the recent years steel fibre reinforced concrete (SFRC), in a volume percentage between 0.75 and 1.25, is being proposed to build slabs supported on piles and slabs supported on columns, where the unique conventional reinforcement is composed of ...

Tunable Synthetic Hydrogel Modulates Hepatic Lineage Specification of Human Liver Organoid

Advanced Functional Materials, EarlyView.
In this study, a synthetic hydrogel is reported that supports the formation of hiPSC‐derived human liver organoids (HLOs). Hepatic lineage specification can be modulated via conjugation of RGD peptide to hydrogel: RGD‐conjugated hydrogels promote cholangiocyte differentiation, whereas RGD‐free hydrogels favor hepatocyte commitment of HLO cells.

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.

3D Multicellular Scaffold Based Model for Advancing Bone Disorder Research

Advanced Functional Materials, EarlyView.
A scalable 3D multicellular in vitro bone model engineered by integrating osteoblasts, osteoclasts, and endothelial cells on biodegradable scaffolds. The system recapitulates key features of human bone remodeling and disease pathology. As a proof of concept, the model mimics osteogenesis imperfecta, demonstrating its potential as a physiologically ...
