LigHTS: Biomimetic Hydrogel Photo‐Fabrication for Imaging‐Based Ultra‐High‐Throughput Screening

open access: yesAdvanced Science, EarlyView.
LigHTS removes a key bottleneck for ultra‐high‐throughput screening (UHTS) by enabling biomimetic hydrogel microenvironments to be manufactured directly in standard multiwell plates. A single, collimated UV exposure with formulation‐tuned light penetration patterns an entire plate with UHTS‐grade uniformity (<20% CV), producing structured GelMA films ...

Turbulent fluctuations above the buffer layer of wall-bounded flows [PDF]

open access: yes, 2008
The behaviour of the velocity and pressure fluctuations in the logarithmic and outer layers of turbulent flows is analysed using spectral information and probability density functions from channel simulations at Reτ _2000.

Improved Deformability of Co‐Free Medium Entropy Oxides by Controlled Entropy Destabilization

open access: yesAdvanced Science, EarlyView.
Controlled entropy destabilization activates defect‐mediated plasticity in Co‐free (CuMgNiZn)O by promoting pre‐existing Cu‐rich secondary phases that serve as defect sources. Temperature‐dependent dislocation activity evolves from limited motion at room temperature to extensive glide and stacking‐fault formation at 600 °C, enabling improved plasticity

Human Engineered Heart Tissues Reproduce Trigger‐ and Substrate‐Driven Mechanisms of Ventricular Tachycardia

open access: yesAdvanced Science, EarlyView.
Engineered heart tissues (EHTs) derived from human iPSCs replicate mechanisms of ventricular tachycardia at the tissue level. Acquired Long‐QT conditions cause early afterdepolarizations, wavebreak, and transient rotors; in contrast, focal cryoinjury forms a stable substrate that supports ongoing reentry.

Hydrodynamic Selection of Polymorphic Assembly Pathways in Plant Protein Amyloid Fibrils

open access: yesAdvanced Science, EarlyView.
Hydrodynamic conditions are revealed to govern polymorphic assembly of soy protein amyloid fibrils. Distinct flow‐induced drafting, kissing, and docking dynamics direct fibril growth into multiple morphologies, linking fluid mechanics with nanoscale assembly and enabling rational design of functional amyloid materials.

Fluid flow and heat transfer in a dual-wet micro heat pipe [PDF]

open access: yes, 2007
Micro heat pipes have been used to cool micro electronic devices, but their heat transfer coefficients are low compared with those of conventional heat pipes. In this work, a dual-wet pipe is proposed as a model to study heat transfer in micro heat pipes.

Multiscale Freestanding Vertically Aligned CNT Heat Sink Enabling Multimodal Heat Dissipation by Conduction, Convection, and Radiation

open access: yesAdvanced Science, EarlyView.
This study demonstrates a vertically aligned CNT (VACNT)‐based heat sink. The nanoporous structure of the VACNT provides a large surface area for convective and radiative exchange, alongside axial conduction, enabling multimodal heat dissipation. Mounted on a CPU, the VACNT with a fin array pattern achieves a steady‐state temperature 6.7°C lower than a

From Materials to Systems: Challenges and Solutions for Fast‐Charge/Discharge Na‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
This review systematically analyzes the key characteristics limiting the fast‐charge/discharge capability of Na‐ion batteries (SIBs) from a multi‐scale perspective encompassing electrode materials, the electrode‐electrolyte interface, and the system. Furthermore, it presents practical solution strategies for the fundamental issues arising at each scale,

Agronomic and Nutritional Perspectives on Vegetable Crops in Africa

open access: yesAgriFood: Journal of Agricultural Products for Food, EarlyView.
Vegetable production plays a key role in food security, nutrition, and livelihoods across Africa. Moreover, African indigenous vegetables emerge as underutilized yet highly valuable crops, rich in macro‐ and micronutrients, as well as bioactive compounds with an array of health benefits.
