Flexible Solid Supercapacitors of Novel Nanostructured Electrodes Outperform Most Supercapacitors.

Sustainable and scalable fabrication of electrode materials with high energy and power densities is paramount for the development of future electrochemical energy storage devices. The electrode material of a supercapacitor should have high electrical conductivity, good thermal and chemical stability, and a high surface area per unit volume (or per unit mass). Researchers have made great efforts to use two-dimensional (2D) nanomaterials, but the separated 2D plates are re-stacked during processing for electrode fabrication, impeding the transport of ions and reducing the number of active sites.

Comparison of Hydrogen Embrittlement Susceptibility of Different Types of Advanced High-Strength Steels.

This study investigated the hydrogen embrittlement (HE) characteristics of advanced high-strength steels (AHSSs). Two different types of AHSSs with a tensile strength of 1.2 GPa were investigated.

Effect of the Molecular Structure Change of a Matrix Polymer (Nylon 6) on the Deformation of Dispersed Phase (a Thermotropic Liquid Crystalline Polymer) Droplets in Shear Flow.

In this work, we investigated the effect of a change in the molecular structure and ensuing molar mass change of a matrix polymer (polyamide 6, Ny 6) on droplet deformation of a dispersed thermotropic liquid crystalline polymer (TLCP, a poly(ester amide)) in shear flow. This study focuses on a total capillary number (the sum of the shear capillary number and the elasticity capillary number) and the viscosity ratio between the TLCP and Ny 6, for the morphological development and mechanical performance of TLCP/Ny 6 blends. In contrast to Ny 6, which has a lower melt viscosity than the TLCP melt, a modified Ny 6 (m-Ny 6) with .

Effect of Cr on Aqueous and Atmospheric Corrosion of Automotive Carbon Steel.

This study investigated the effect of Cr alloying element on the corrosion properties of automotive carbon steel (0.1C, 0.5Si, 2.

Optimization of Pickling Solution for Improving the Phosphatability of Advanced High-Strength Steels.

This study investigated the optimum pickling conditions for improving the phosphatability of advanced high-strength steel (AHSS) using surface analysis and electrochemical measurements. To remove the SiO that forms on the surface of AHSS, 30 wt.% NHHF was added to the pickling solution, resulting in a significant reduction in the amount of SiO remaining on the surface of the AHSS.

A Turnip Mosaic Virus Determinant of Systemic Necrosis in and a Novel Resistance-Breaking Determinant in Chinese Cabbage Identified from Chimeric Infectious Clones.

Infectious clones of Korean turnip mosaic virus (TuMV) isolates KIH1 and HJY1 share 88.1% genomic nucleotides and 96.4% polyprotein amino acid identity, and they induce systemic necrosis or mild mosaic, respectively, in .

Simultaneous occurrence of diabetic ketoacidosis, thyroid storm, and multiple cerebral infarctions due to Moyamoya disease.

Diabetic ketoacidosis (DKA) is one of the precipitating factors that can evoke a thyroid storm. Thyroid storm may cause cerebral ischemia in Moyamoya disease, which can coexist in patients with Graves' disease. A 16-year-old girl complaining of dizziness and palpitations visited the emergency department and was diagnosed with DKA combined with hyperthyroidism.

Development and validation of the Yin deficiency scale.

Objectives: Yin Deficiency (YD) is a pathophysiologic pattern that manifests with emaciation, dry mouth, tidal fever, Five Center Heat, night sweats, and malar flushing. The purpose of the present study was to develop and validate a new YD metric, the Yin Deficiency Scale (YDS), to define an optimum cutoff point for the YDS, and to examine the relationships between YD and Cold-Heat patterns.

Methods: A total of 169 outpatients and 83 college students were asked to complete the YDS.

Absorption characteristics of new solvent based on a blend of AMP and 1,8-diamino-p-menthane for CO2 absorption.

Aqueous 1,8-diamino-p-menthane (KIER-C3) and commercially available amine solutions were tested for CO2 absorption. A 2-amino-2-methyl-1-propanol (AMP) solution with an addition of KIER-C3 showed 9.3% and 31.

[The proportional mortality ratios of specific-cause mortality by occupation and education among men aged 20-64 in Korea (1993-2004)].

Objectives: This study investigated the relationship of occupational class and educational background with proportional mortality ratios in Korea.

Methods: Mortality was investigated using the entire registered death data from 1993 to 2004, obtained from the Korean National Statistics Office. Proportional mortality ratios (PMRs) for specific diseases were calculated according to the occupational class and educational background of men aged 20-64.

Morpholin-2-one derivatives as novel selective T-type Ca2+ channel blockers.

Morpholin-2-one-5-carboxamide derivatives were prepared by using the one-pot Ugi multicomponent reaction and evaluated for blocking effects on T- and N-type Ca(2+) channels. Among them, compound 5i produced the highest potency (IC(50)=0.45+/-0.

An efficient synthesis of 2,5-diketopiperazine derivatives by the Ugi four-center three-component reaction.

A facile synthetic approach to 2,5-diketopiperazines 4 by the Ugi four-center three-component reaction using commercially available dipeptides as a bifunctional component, aldehydes, and isocyanides was described.
