Low strain rate mechanical performance of balsa wood and carbon fibre-epoxy-balsa sandwich structures

Composites Part C: Open Access, 2023
The focus of this study is the experimental assessment of the mechanical behaviour of balsa wood and its sandwich structures, where balsa serves as the core, supported by carbon fibre-epoxy skin layers.

Bending analysis of sandwich panel composite with a re-entrant lattice core using zig-zag theory

Scientific Reports, 2022
The sandwich panel structures have been widely used in many industrial applications because of their high mechanical properties. The middle layer of these structures is very important factor in controlling and enhancing their mechanical performance under

Finite Element Analysis of Sandwich Structures [PDF]

, 1991
Sandwich construction may be defined as a three-layer type of construction where a relatively weak, low-density core material supports and stabilizes thin layers of high strength face material Its typical features, namely high strength-thin and low strength-thick materials, interfaces, bonding and load transfer suggest that each of the layers will ...

Energy-based fracture characterization of adhesive joints using adhesively bonded short-beam bend test

Scientific Reports
Mode-I fracture in adhesive joints was characterized using an adhesively bonded short-beam bend (ABSBB) test, which involves a cracked rectangular bonded joint subjected to three-point bending, and a compliance-based beam method (CBBM).

Spatial and single‐nuclei transcriptomics reveals idiosyncratic and generic patterns in papillary and anaplastic thyroid cancers

Molecular Oncology, EarlyView.
Matched spatial transcriptomics and single‐nuclei RNA‐seq were generated for anaplastic and BRAFV600E papillary thyroid cancers revealing generic and tumor‐specific states occurring in cancer cells and in the tumor microenvironment. In this context, cancer dedifferentiation mirrored organoid maturation through ordered thyroid marker gain/loss ...

Optimization of load introduction points in sandwich structures with additively manufactured cores

Design Science, 2020
This paper presents how numerical optimization methods, like topology optimization, and new design possibilities through additive manufacturing (AM) can be used for structural improvements of the load introduction points in sandwich structures.

Hyperactive ice‐binding proteins stabilize cell membranes and improve resistance to dehydration stress in Caenorhabditis elegans

FEBS Open Bio, EarlyView.
TisIBP8, a fungal‐derived hyperactive ice‐binding protein, helps Caenorhabditis elegans survive dehydration. It localizes near cell membranes, reduces cell damage, and helps maintain membrane structure during drying. These results suggest that ice‐binding proteins can protect cells from dehydration stress as well as freezing stress.

Identifying and characterising a plant GH1 β‐glucosidase that exhibits hydrolytic activity on N‐linked glucopyranoside

FEBS Open Bio, EarlyView.
We report the first β‐glucosidase with demonstrated hydrolytic activity on an N‐linked glycopyranoside. The enzyme, native to maize, was biochemically characterised for this novel reaction, and structural modelling of the enzyme–substrate complex revealed several clues to the underlying reduced catalytic rate relative to its native O‐glycopyranoside ...
