Advanced Functional Materials, EarlyView.Ag+‐mediated hydrothermal crystal engineering promotes preferential [hk1]‐oriented growth of Sb2Se3 via an ultrathin MoOx interlayer, improving crystallinity and suppressing non‐radiative recombination. The optimized Ag+ treatment photocathode delivers 24.7 mA cm−2 at 0 VRHE and improved stability, revealing an ion‐modulated route to high‐performance ...

Platypnea-orthodeoxia: Patent foramen ovale unmasked by pulmonary emboli
Indian Journal of Respiratory Care, 2018 This report describes an 84 year old woman who presented with breathlessness from platypnea-orthodeoxia. This was due to a distortion of a patent foramen ovale by lower thoracic vertebral fractures which allowed a right-to-left intracardiac shunt.

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020 Approximately 50% of patients with heart failure have preserved ejection fraction. Although a wide variety of conditions cause or contribute to heart failure with preserved ejection fraction, elevated left ventricular filling pressures, particularly ...

Advanced Functional Materials, EarlyView.Conventional unstable electron transport layers (ETLs) limit self‐powered organic sensors. This work resolves this by developing a n‐type self‐assembled monolayer (SAM), “3‐PAPh”. This SAM forms a chemically stable and structurally ordered interface that fundamentally suppresses defect formation.

Arachnoid cyst: adversity ans plasticity [PDF]
Arquivos de Neuro-Psiquiatria, 1999 We report four cases of surgically treated intracranial arachnoid cysts, one with cyst-peritoneal shunt and three with craniotomy and arachnoid membrane resection. Their classification and etiopathogeny are discussed, and especially the different methods

Malignant refractory priapism: An urologist's nightmare
Urology Annals, 2019 Malignant priapism is described as persistent, nonsexual erections caused by invasion or metastasis from a primary neoplasm. We present two cases of malignant priapism with different etiologies and the respective management strategies.

Voltage bias induced modification of all oxide Pr0.5Ca0.5MnO3/SrTi0.95Nb.05O3 junctions
, 2011 In this paper we report what happens to a pristine oxide junction Pr0.5Ca0.5MnO3/SrTi0.95Nb.05O3 (PCMO/Nb:STO), when it is subjected to cycling of voltage bias of moderate value ({\pm}4V).

Advanced Functional Materials, EarlyView.A pixelation‐free, monolithic iontronic pressure sensor enables simultaneous pressure and position sensing over large areas. AC‐driven ion release generates spatially varying impedance pathways depending on the pressure. Machine learning algorithms effectively decouple overlapping pressure–position signals from the multichannel outputs, achieving high ...
