Numerical investigation of the behaviour of shallow foundations under reverse fault rupture using concrete damage plasticity model

Scientific Reports
Fault ruptures pose a major threat to structures, yet conventional numerical models often oversimplify foundation behavior by assuming linear elasticity.

Effect of Calendering and Surface Treatment on the Thermochromic Response of Cholesteric Liquid Crystals on PET Nonwovens

Advanced Engineering Materials, EarlyView.
This study explores the influences of calendering and surface treatment during direct ink writing (DIW) of thermochromic cholesteric liquid crystal (CLC) on PET nonwovens. For the PVA‐coated nonwovens, calendering reduces pore size leading to reduced ink absorption and enhanced spreading. The NeverWet‐coated nonwovens improve thermochromic responses by

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.

Modelling distortion reduction on pre- and post-weld rolled gas metal arc welded plates [PDF]

, 2011
Residual stress generated during welding can cause distortion, especially when appliedon relatively thin plates. There are several standard and well documented techniquesto reduce distortion and residual stress after welding, however these techniques ...

Development of Simplified Mechanical Model for Welding Deformation in Multi-Pass Welding

Journal of Manufacturing and Materials Processing
This paper proposes a simplified mechanical model to estimate transverse shrinkage and angular distortion in multi-pass butt welding. The simplified mechanical model is first derived for an I-groove joint by representing the heated weld region with one ...

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Formularization of Angular Distortion Induced by Multiple Heat Sources on the Same Surface [PDF]

A preceding heat welding is proposed for reducing weld distortion. In this welding process, MAG welding is followed by a preceding heating with TIG on the same surface side of welding.

Inferring sedimentary basin structure from multitemporal InSAR mapping of urban land subsidence: the Vallès Basin (Barcelona, Spain)

Journal of Maps
Land subsidence in the Vallès Depression (north of Barcelona) was investigated using multi-temporal PS-InSAR analysis based on ENVISAT (2003–2010), TerraSAR-X (2007–2011), and Sentinel-1 (2015–2020) satellite data.

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

Advanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

The influence of gas metal arc welding on angular distortion of T-joint [PDF]

, 2014
Gas Metal Arc Welding (GMAW) or gas metal arc welding is one of the joining technologies and widely used in metal fabrication. The quality of a joint is greatly influenced by the selection of parameter setting of GMAW.
