Computer Aided Design and Structural Analysis of a Rim [PDF]

open access: yes, 2016
Automobile wheel is an important component in vehicles to support the vehicle weight and maintain the contact between the vehicle body and road. Automotive wheels have evolved over the decades using materials from steels to aluminum and magnesium alloys.

Dewetting dynamics of stressed viscoelastic thin polymer films

open access: yes, 2008
Ultrathin polymer films that are produced e.g. by spin-coating are believed to be stressed since polymers are 'frozen in' into out-of-equilibrium configurations during this process. In the framework of a viscoelastic thin film model, we study the effects

Surface Diffusion in SnTe‐PbTe Monolayer Lateral Heterostructures

open access: yesAdvanced Functional Materials, EarlyView.
The lateral heterostructures between 2D materials often suffer from the interdiffusion at the interfaces. Here, a surface diffusion mechanism is found to be dominating at the interfaces between semiconducting SnTe and PbTe monolayers. Atomically sharp interfaces can be achieved by suppressing this diffusion process. ABSTRACT The construction of complex

Quantitative analysis of bone reactions to relative motions at implant-bone interfaces [PDF]

open access: yes, 1993
Connective soft tissues at the interface between implants and bone, such as in human joint replacements, can endanger the stability of the implant fixation. The potential of an implant to generate interface bone resorption and form soft tissue depends on

Decoupling Dynamics and Crosslink Stability in Supramolecular Hydrogels Using Associative Exchange

open access: yesAdvanced Materials, EarlyView.
How does reorganization impact the stability of supramolecular hydrogels? In contrast to dissociative crosslink exchange, implementing associative exchange in macroscale DNA hydrogels enables decoupling of reorganization dynamics from thermal and mechanical stability.

CdTe Quantum Dots Encapsulated on Perovskite Grains Enable Highly Efficient and Stable Perovskite Solar Cells

open access: yesAdvanced Materials, EarlyView.
Present work demonstrates an efficient laser‐assisted localized interfacial engineering strategy that achieves epitaxial‐grade atomic coherence in spatially defined p‐n microscopic heterointerfaces, via precisely embedding p‐type CdTe QDs into an n‐type perovskite matrix, which concurrently establishes dual optimization of microscale carrier management

Molecular switching in transcription through splicing and proline-isomerization regulates stress responses in plants

open access: yesNature Communications
The Arabidopsis thaliana DREB2A transcription factor interacts with the negative regulator RCD1 and the ACID domain of subunit 25 of the transcriptional co-regulator mediator (Med25) to integrate stress signals for gene expression, with elusive molecular

Apparatus and method for reducing thermal stress in a turbine rotor [PDF]

open access: yes, 1978
A gas turbine is described wherein the thermal stresses in the turbine rotor are reduced. The rotor includes a central disc with a peripheral rim, and a plurality of blades extending radially outward from the rim.

Multi‐scale Engineered Vasculature and Hierarchical Porosity via Volumetric Bioprinting‐Guided Photopolymerization‐Induced Phase Separation

open access: yesAdvanced Materials, EarlyView.
Vascularization in bioprinted hydrogels is limited by nanoscale porosity in hydrogel bionks. Volumetric bioprinting of gelatin–norbornene phase‐separating hydrogels permits to create centimeter‐scale constructs featuring interconnected multi‐scale porosity. Light dose gradients result in spatially controlled pore dimensions. Capillary‐scale vessels are

Serotonergic System‐Targeted Nucleic Acid Hydrogel Coordinates Excitability Restoration and Circuit Reconstruction for Spinal Cord Injury Therapy

open access: yesAdvanced Materials, EarlyView.
The study reports a DNA/RNA heteroduplex hydrogel (SeroPTEN‐CG) that undergoes DNase‐mediated hydrogel‐to‐nanogel transition for spinal cord injury therapy by targeting the serotonergic system, combining 5‐hydroxytryptamine (5‐HT)‐mediated excitability restoration to reactivate dormant interneurons with phosphatase and tensin homolog (PTEN)‐targeted ...
