Mechanical Stress Evolution in Polycrystalline Ge Thin Films Under MeV Ion Irradiation

Advanced Materials Interfaces, EarlyView.
Irradiation of polycrystalline Ge thin films with 1.8 MeV Au ions alters residual stress through defect generation and lattice expansion. Increasing fluence drives progressive lattice disorder and eventual amorphization. Polycrystalline Ge resists amorphization longer than crystalline Ge, as grain boundaries facilitate defect diffusion, significantly ...

Adverse effects of intracardiac dyssynchrony and right ventricular pacing on contractile function and prognosis

Российский кардиологический журнал
Pacemaker-induced cardiomyopathy (PICM) is a complication of frequent right ventricular pacing, which in most studies is regarded as a decrease in the left ventricular ejection fraction with constant right ventricular pacing.

Water‐Stable Paper‐Based Laser‐Induced Graphene With Asymmetric Water Adhesion and Wettability

Advanced Materials Interfaces, EarlyView.
Paper‐based electronics are attractive for sustainable and disposable devices, but often fail in wet environments. By introducing Parafilm into cellulose paper combined with laser conversion, two graphene surfaces with different water interactions are created.

Heart Failure with Preserved Ejection Fraction

Current Emergency and Hospital Medicine Reports, 2019
The incidence of heart failure with preserved ejection fraction (HFpEF] is rapidly increasing, yet many physicians may feel less knowledgeable about HFpEF when compared with heart failure with reduced ejection fraction (HFrEF]. The purpose of this review is to discuss the incidence, pathophysiology, clinical diagnosis, treatment, and prognosis of ...

Magnetic Textiles: A Review of Materials, Fabrication, Properties, and Applications

Advanced Materials Technologies, EarlyView.
Magnetic textiles (M‐textiles) are emerging as a programmable materials platform that merges magnetic matter with hierarchical textile structures. This article consolidates magnetic material classes, textile architectures, and fabrication and magnetization strategies, revealing structure–property–function relationships that govern magneto‐mechanical ...

Prognostic significance of GDF 15 and NTproBNP levels and echocardiographic parameters in patients with heart failure with preserved ejection fraction and asymptomatic diastolic dysfunction after myocardial infarction on the background of arterial hyperte

Zaporožskij Medicinskij Žurnal, 2014
Aim. Chronic heart failure with preserved ejection fraction is related to syndromes with a poor prognosis. 93 patients with preserved left ventricular ejection fraction (EF>45%) after myocardial infarction on the background of arterial hypertension were ...
