A Tracer Diffusion Study of Diverse Photo‐Ionic Phenomena in Strontium Titanate

Advanced Functional Materials, EarlyView.
Two strong interfacial photo‐ionic effects are demonstrated for the model system SrTiO3 through the application of isotope exchange experiments: UV illumination is found to enhance the oxygen surface exchange coefficient by several orders of magnitude and to depress the surface space‐charge potential substantially.

非细菌性血栓性心内膜炎与卒中 Nonbacterial Thromboendocarditis and Stroke

Zhongguo cuzhong zazhi, 2019
【摘要】 非细菌性血栓性心内膜炎（nonbacterial thromboendocarditis，NBTE）是一种异质性疾病，以心脏瓣膜赘生物形成为特征。NBTE与恶性肿瘤及其他原因所致的高凝状态有关，是引起隐匿性卒中的原因之一。经食道超声心动图和头颅MRI是诊断NBTE相关卒中的重要方法。合并恶性肿瘤的NBTE患者发生卒中的风险较正常人群高，短期内卒中的复发率高、预后差。因此，早期识别NBTE相关性卒中，并开展相应的治疗和二级预防是值得临床关注的问题 ...

Alkali Ion‐Incorporated HfO2 Dielectrics for Reconfigurable Neuromorphic Computing

Advanced Functional Materials, EarlyView.
This work presents an indium gallium zinc oxide (IGZO) transistor with an alkali cation‐integrated hafnium dioxide (HfO2) dielectric exhibiting synaptic behavior via ion retention. The solution‐based film fabrication strategy overcomes the limitations of atomic layer deposition (ALD) and precursor coating, enabling the control of synaptic retention ...

Pore Size Effects of Mesoporous N‐Doped Carbon Nanospheres as Advanced Support Material on the Activity of Molybdenum Sulfide Catalysts for the Hydrogen Evolution Reaction

Advanced Functional Materials, EarlyView.
By tuning the pore size of mesoporous N‐doped carbon (MPNC) nanospheres as support material for molybdenum sulfide, the electrochemical activity of the composite material for the hydrogen evolution reaction can be optimized. An ideal MPNC pore size of 60 nm allows a high number of molybdenum sulfide active sites while maintaining efficient proton and ...

Dual‐Interface Engineering of the Source Electrode to Overcome the Intrinsic Injection‐Leakage Trade‐Off in Organic Schottky Barrier Transistors

Advanced Functional Materials, EarlyView.
A charge injection layer is introduced via RIE to decouple the dual functions of the source electrode: lowering contact resistance through doping to enhance charge injection, while SAM modification on the top surface minimizes leakage current. This strategy enables OSBTs to achieve a high on/off ratio with improved stability and performance.

Klebsiella pneumoniae-Induced Emphysematous Prostatic Abscess Accompanied by a Spinal Cord Infarction: Case Report [PDF]

Urogenital Tract Infection
Various strains can be found in emphysematous prostatic abscesses (EPAs), but the most frequent causative organism is Klebsiella pneumoniae. Hypervirulent K. pneumoniae can disseminate to distant sites by forming a muco-polysaccharide network outside the

Adaptive 4D‐Printed Vascular Stents With Low‐Temperature‐Activated and Intelligent Deployment

Advanced Functional Materials, EarlyView.
Microarchitected coronary artery stents were fabricated using a polycaprolactone (PCL)‐based shape memory polymer (SMP) composite via projection micro‐stereolithography (PµSL) 4D printing. By incorporating diethyl phthalate (DEP) as a plasticizer, the thermal transition temperature (Ttran) was modulated to about 37°C, enabling rapid and autonomous ...
