Ultra-Large Room-Temperature Compressive Plasticity of a Nanocrystalline Metal

open access: yes, 2007
We report ultra-large room-temperature plasticity of nanocrystalline Ni subjected to uniaxial compression. Up to 200% true plastic strain is achieved with a steady flow stress of ∼2 GPa at strain rates ranging from 10-3 to 10-1 s-1.

Cell‐Free DNA as a Biomarker of Cell Death and Treatment Response for On‐Chip Three‐Dimensional Tumor Models

open access: yesAdvanced Healthcare Materials, EarlyView.
This study presents quantifying cell‐free DNA (cfDNA) as a non‐disruptive and rapidly quantifiable method for assessing cell death for on‐chip 3D sarcoma tumor models. On‐chip cfDNA release reflects tumor burden, extent of cell death, and survival of in vitro and ex vivo 3D models, providing valuable insight into the temporal response of tumor models ...

Low-temperature magnetic properties of magnetite [PDF]

open access: yes, 2000
Although several studies have recommended removal of secondary components of magnetic remanence by zero-field cycling from room temperature to a temperature much lower than the low temperature transition for magnetite (about 120 K), the method has not ...

Lignin Mimicking Protein Methylation Augments the Efficacy of FOLFOX Chemotherapy by Anchoring Thymidylate Synthase

open access: yesAdvanced Materials, EarlyView.
Lignin‐mimicking protein methylation can enhance the efficacy and mitigate the toxicity of the classic FOLFOX chemotherapy regimen. ABSTRACT FOLFOX has served as the standard chemotherapy regimen for advanced stages, specifically in the treatment of pancreatic, colorectal, and bladder cancers.

Clustomesogen Showing Sub‐Zero Liquid Crystal Properties: Supramolecular Assembly Between Cs2[Mo6Ii8(OCOC2F5)6] and Hexaethylenoxide Containing Mesogenic Dimers

open access: yesAdvanced Materials, EarlyView.
Associating a red‐NIR phosphorescent octahedral hexanuclear molybdenum cluster compound with hexaethyleneoxide chains bearing mesogenic units on both ends leads to an emissive hybrid liquid crystal showing mesomorphism on a very unusual temperature range down to −25°C.

Unveiling Exsolution‐Induced Giant Electronic and Magnetic Property Changes in Non‐Stoichiometric Titanate Perovskite Thin Films

open access: yesAdvanced Materials, EarlyView.
A giant insulator to metal transition and emergent superparamagnetism are revealed by nanoparticle exsolution in non‐stoichiometric titanate perovskite thin films. By combining transport, synchrotron spectroscopy, and first‐principles calculations, this work reveals how defect reconfiguration and lattice reconstruction fundamentally reshape electronic ...

Hydrophobic MFI‐Type Zeolites via Alkali‐Cation‐Induced Defect Healing: Implications for Adsorbent and Catalyst Design

open access: yesAdvanced Materials, EarlyView.
Sub‐stoichiometric amounts of Na+ or K+ enhance defect healing during Silicalite‐1 (MFI) and TS‐1 calcination by promoting Si–O–Si annealing and healing framework vacancies. The resulting defect‐free zeolites are more hydrophobic and show improved butanol/water separation and improved activity and selectivity in the epoxidation of 1‐hexene, offering a ...
