Defects induced ferromagnetism in Mn doped ZnO

, 2010
Single phase Mn doped (2 at %) ZnO samples have been synthesized by solid-state reaction technique. Before the final sintering at 500 C, the mixed powders have been milled for different milling periods (6, 24, 48 and 96 hours).

Engineering Pt Single‐Atom Doped SeS2/Ti3CNTx MXene with Molecularly Imprinted Polymer for Precision Pancreatic Cancer Diagnostics: DFT and Molecular Dynamics Perspectives

Small Methods, EarlyView.
A novel approach is developed to pancreatic cancer screening by targeting the cyclophili‐B (CypB)protein using a molecularly imprinted polymer with the electrode material containing Pt single‐atom‐doped/SeS2‐Ti3CNTx MXene. The quantification of CypB in pancreatic cancer tissues provide an insight into the association of CypB with pancreatic cancer ...

Stable fourfold configurations for small vacancy clusters in silicon from ab initio calculations

, 2004
Using density-functional-theory calculations, we have identified new stable configurations for tri-, tetra-, and penta-vacancies in silicon. These new configurations consist of combinations of a ring-hexavacancy with three, two, or one interstitial atoms,

Effect of high‐intensity interval exercise on metformin pharmacokinetics in healthy men, assessed through a population pharmacokinetic model

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Metformin and exercise are first‐line therapies for prediabetes and type 2 diabetes. However, it is unclear whether the combination of metformin and exercise is synergistic or antagonistic. The aim of this study was to investigate the effect of exercise on metformin pharmacokinetics and help clarify the contradictory ...

Influence of the filler content on the free nanohole volume in epoxy-based composites

eXPRESS Polymer Letters, 2013
A study on free nanohole volumes in particulate epoxy matrix composites as a function of the aluminum particles content is presented. Specifically, the influence of the filler content in the epoxy matrix on the nanohole volume is analyzed in terms of the

Investigation of the chemical vicinity of crystal defects in ion-irradiated Mg and AZ31 with coincident Doppler broadening spectroscopy

, 2007
Crystal defects in magnesium and magnesium based alloys like AZ31 are of major importance for the understanding of their macroscopic properties. We have investigated defects and their chemical surrounding in Mg and AZ31 on an atomic scale with Doppler ...

Uncovering the impact of the cardiovascular system on cerebrovascular health using MRI

Experimental Physiology, EarlyView.
Abstract Human cerebrovasculature is finely tuned to enable local changes in blood flow to meet the brain's demands, whilst protecting the brain from systemic changes in blood pressure, both acutely during a heartbeat and chronically over time. This review summarises cerebrovascular structure and function, their role in disease and neurodegeneration ...
