Nanoindentation response of semiconductors

open access: yesMoldavian Journal of the Physical Sciences, 2008
The paper reviews the nanoindentation behaviour of semiconductors under concentrated load. We consider first, fundamental aspects regarding the mechanical resistance to contact loading of semiconductor single crystals (indentation strain, hardness ...

Snustorr Defines Cuticle Elasticity in Drosophila melanogaster. [PDF]

open access: yesArch Insect Biochem Physiol
Sir Wigglesworth postulated that insect cuticle hardening depended on the incorporation of lipids into the upper parts of the cuticle. We show that the delivery of these lipids needed for cuticle hardening requires the ABC transporter Snu in the fruit fly Drosophila melanogaster larva.

Bioinspired Microphase‐Engineered Binders for Silicon Anodes

open access: yesAdvanced Science, EarlyView.
Inspired by the tough exoskeleton of Phloeodes diabolicus, a bio‐based binder featuring LRA–click chemistry and hierarchical crosslinking forms well‐defined microphase‐separated structures that enable robust silicon anodes. This system promotes the formation of a LiF–rich, ultrathin SEI (∼17 nm) with high modulus and ionic conductivity, ensuring long ...

Study of the Mechanical Properties of a Nanostructured Surface Layer on 316L Stainless Steel

open access: yesAdvances in Materials Science and Engineering, 2016
A nanostructured surface layer (NSSL) was generated on a 316L stainless steel plate through surface nanocrystallization (SNC). The grains of the surface layer were refined to nanoscale after SNC treatment.

Engineered Strain in 2D Materials by Direct Growth on Deterministically Patterned Grayscale Topographies

open access: yesAdvanced Science, EarlyView.
ABSTRACT Strain is a proven technique for modifying the bandgap and enhancing carrier mobility in 2D materials. Most current strain engineering techniques rely on the post‐growth transfer of these atomically thin materials from growth substrates to target surfaces, limiting their integration into nanoelectronics.

Mechanism of Solid Solution‐Driven Texture Induced by Ag Doping in YBCO Superconductor

open access: yesAdvanced Science, EarlyView.
Ag‐doped YBCO with a designed concentration gradient is produced by dual‐material co‐extrusion and freeze‐drying. During annealing, Ag+ ions diffuse into Y123, substituting for Cu(1) and inducing c‐axis relaxation. This leads to the formation of [001]‐oriented YBCAO, creating a coherent interface that templates the textured growth of Y123. Consequently,

Piezo1 Channel Mediates Mechanically Programmable Drug Delivery to Potentiate Intravesical Chemotherapy

open access: yesAdvanced Science, EarlyView.
This study utilizes programmable mechanical pressure as a therapeutic enhancer to establish a mechano‐chemotherapy strategy. Controlled pressure activates the mechanosensitive ion channel Piezo1 in bladder cancer, triggering a calcium ion cascade that transiently and reversibly amplifies membrane permeability to chemotherapeutics.

Dynamic Covalent Networks of Molecular Clusters for Hard and Impact‐Resistant Glass with Feasible Processability

open access: yesAdvanced Science, EarlyView.
Molecular granular material glass is fabricated by crosslinking sub‐nm POSS clusters with dynamic borate ester bonding while the materials combine high transparency, modulus, and hardness with superior impact resistance and (re)processability, offering a promising strategy for creating robust yet highly processable organic glasses.

Annealing‐Induced Plasticity and Strengthening in Metallic Glasses

open access: yesAdvanced Science, EarlyView.
This work challenges the dogma that annealing inevitably embrittles metallic glasses. We demonstrate that sub‐Tg annealing, guided by positive mixing enthalpy and constrained kinetics, can drive a self‐organized compositional fluctuation that creates an interface‐free heterogeneous structure.
