Slip Effects on the Unsteady Stagnation Point Flow with Variable Free Stream

Walailak Journal of Science and Technology, 2013
We perform a study for the boundary layer flow of viscous fluid about a stagnation point on an unsteady stretching sheet in the presence of variable free stream. Both the velocity and thermal slip conditions are taken into consideration.

A Living Multi‐Omics PDX Biobank of High‐Risk Sarcomas Reveals ecDNA‐Driven Oncogene Amplification in Osteosarcoma and Enables Preclinical Precision Oncology

Advanced Science, EarlyView.
A living multi‐omics sarcoma PDX biobank is enriched for high‐risk disease and preserves key patient tumor features at histopathological and molecular levels. Integrated profiling reveals ecDNA‐driven oncogene amplification in osteosarcoma and preferential retention of ecDNA during PDX evolution.

Advancing Biotherapeutic Treatment of Ulcerative Colitis Using Lipid Mesophases: Formulation Design and Preclinical Validation

Advanced Science, EarlyView.
Lipid mesophases provide a versatile platform for colon‐targeted delivery of biotherapeutics, protecting them from degradation while enhancing mucoadhesion and enabling localized, controlled release to the inflamed mucosa after oral or rectal administration. In a DSS‐induced colitis model, this strategy reduced disease activity, inflammatory biomarkers,

Product‐Reshaped Gas‐Phase Hydrodynamics Govern CO2 Electrolysis in Gas Diffusion Electrodes

Advanced Science, EarlyView.
In gas‐fed CO2${\rm CO}_2$ electrolysers, the gas phase is part of the electrochemical response. As gaseous products form, they change gas composition and flow, which in turn affects CO2${\rm CO}_2$ delivery and CO intermediate availability. This feedback changes the reaction environment needed for multicarbon formation, becoming unavoidable as ...

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

Advanced 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
