Porous SnO/C Nanofiber Anodes and LiFePO/C Nanofiber Cathodes with a Wrinkle Structure for Stretchable Lithium Polymer Batteries with High Electrochemical Performance.

Stretchable lithium batteries have attracted considerable attention as components in future electronic devices, such as wearable devices, sensors, and body-attachment healthcare devices. However, several challenges still exist in the bid to obtain excellent electrochemical properties for stretchable batteries. Here, a unique stretchable lithium full-cell battery is designed using 1D nanofiber active materials, stretchable gel polymer electrolyte, and wrinkle structure electrodes.

Dataset on the effect of the reaction temperature during spray pyrolysis for the synthesis of the hierarchical yolk-shell CNT-(NiCo)O/C microspheres.

The data presented in this article are related to the research article entitled "Hierarchical yolk-shell CNT-(NiCo)O_C microspheres prepared by one-pot spray pyrolysis as anodes in lithium-ion batteries" (Oh et al., 2019). The data presented in this manuscript showed the effect of the reaction temperature during spray pyrolysis on the obtained microspheres morphology.

Rattle-type porous Sn/C composite fibers with uniformly distributed nanovoids containing metallic Sn nanoparticles for high-performance anode materials in lithium-ion batteries.

Rattle-type porous Sn/carbon (Sn/C) composite fibers with uniformly distributed nanovoids containing metallic Sn nanoparticles in void space surrounded by C walls (denoted as RT-Sn@C porous fiber) were prepared by electrospinning and subsequent facile heat-treatment. Highly concentrated polystyrene nanobeads used as a sacrificial template played a key role in the synthesis of the unique structured RT-Sn@C porous fiber. The RT-Sn@C porous fiber exhibited excellent long-term cycling and rate performances.

Three-dimensionally ordered mesoporous multicomponent (Ni, Mo) metal oxide/N-doped carbon composite with superior Li-ion storage performance.

Among the various nanostructures, porous materials with controlled pore structures have been widely used for designing transition metal-based anode materials for lithium-ion batteries, because they provide good access to electrolyte and can effectively accommodate stress arising from volume changes. In particular, ternary transition metal oxide materials containing nanovoids, arranged with high degree of periodicity, are ideal for enhancing lithium-ion storage capability. In this study, we provide a method using spray pyrolysis for the synthesis of mesoporous multicomponent metal oxide microspheres containing Ni and Mo components and N-doped carbon, in which three-dimensionally ordered 40 nm-sized mesopores are interconnected.

Drug-induced liver injury caused by iodine-131.

Iodine-131 is a radioisotope that is routinely used for the treatment of differentiated thyroid cancer after total or near-total thyroidectomy. However, there is some evidence that iodine-131 can induce liver injury . Here we report a rare case of drug-induced liver injury (DILI) caused by iodine-131 in a patient with regional lymph node metastasis after total thyroidectomy.

Evaluation of antimicrobial effects of commercial mouthwashes utilized in South Korea.

Streptococcus mutans is frequently associated with dental caries. Bacterial fermentation of food debris generates an acidic environment on the tooth surface, ultimately resulting in tooth deterioration. Therefore, various mouthwashes have been used to reduce and prevent Streptococcus mutans.

Vicinal difunctionalization of alkenes: chlorotrifluoromethylation with CF3SO2Cl by photoredox catalysis.

Photoredox-catalyzed vicinal chlorotrifluoromethylation of alkene is described. In the presence of Ru(Phen)3Cl2, CF3SO2Cl was used as a source for the CF3 radical and chloride ion under visible light irradiation. Various terminal and internal alkenes were transformed to their vicinal chlorotrifluoromethylated derivatives.

Simultaneous detection of waterborne viruses by multiplex real-time PCR.

Norovirus, Rotavirus group A, the Hepatitis A virus, and Coxsackievirus are all common causes of gastroenteritis. Conventional diagnoses of these causative agents are based on antigen detection and electron microscopy. To improve the diagnostic potential for viral gastroenteritis, internally controlled multiplex real-time polymerase chain reaction (PCR) methods have been recently developed.

Standardized positive controls for detection of norovirus by reverse transcription PCR.

Background: Norovirus is one of the most common causes of nonbacterial gastroenteritis in humans. Rapid spread by contaminated food and person-to-person transmission through the fecal-oral route are characteristics of norovirus epidemiology and result in high morbidity in vulnerable patient populations. Therefore, detection of norovirus is a major public health concern.
