Characterization of the inhomogeneity of Pt/CeO /Pt resistive switching devices prepared by magnetron sputtering.

There are unrevealed factors that bring about the performance variations of resistive switching devices. In this work, Pt/CeO /Pt devices prepared by magnetron sputtering showed rectification in their asymmetrical current-voltage (I-V) curves during voltage sweeps. X-ray photoelectron spectroscopy showed that the deposited CeO film had an inhomogeneous composition, and more oxygen vacancies existed in CeO near the top electrode.

Synthesis, characterization, and debromination reactivity of cellulose-stabilized Pd/Fe nanoparticles for 2,2',4,4'-tretrabromodiphenyl ether.

In this study, two kinds of cellulose derivatives (polyanionic cellulose (PAC) and hydroxypropylmethyl cellulose (HPMC)) were selected as stabilizers of Pd/Fe nanoparticles (NPs) to investigate their influences on the debromination performances of 2,2',4,4'-tretrabromodiphenyl ether (BDE47). Field emission scanning electron microscope (FE-SEM) images revealed that the cellulose-stabilized Pd/Fe NPs were smaller and more uniform than the bare-Pd/Fe NPs. X-ray diffractometer (XRD) and X-ray photoelectron spectroscopy (XPS) results suggested that cellulose coatings found on Pd/Fe NPs surfaces featured some antioxidation abilities, which followed the order of HPMC < PAC.

Variant GADL1 and response to lithium therapy in bipolar I disorder.

Background: Lithium has been a first-line choice for maintenance treatment of bipolar disorders to prevent relapse of mania and depression, but many patients do not have a response to lithium treatment.

Methods: We selected subgroups from a sample of 1761 patients of Han Chinese descent with bipolar I disorder who were recruited by the Taiwan Bipolar Consortium. We assessed their response to lithium treatment using the Alda scale and performed a genomewide association study on samples from one subgroup of 294 patients with bipolar I disorder who were receiving lithium treatment.

Development of a chinese version of the Yale-Brown obsessive compulsive scale for heavy drinking.

Background: Measurement of craving is an important component in the investigation of the etiology and clinical pictures of alcoholism and dependence of other substances in different cultures. The aim of this study was to develop a Chinese version of the Yale-Brown Obsessive Compulsive Scale for heavy drinking (YBOCS-hd-C), the instrument most frequently used in assessing the severity of alcohol craving in Taiwan.

Methods: Four hundred twenty Han Chinese (220 with alcohol use disorders) and 218 Bunun aborigines (150 with alcohol use disorders) in Taiwan were interviewed by mental health professionals with the YBOCS-hd-C and a Chinese version of the World Health Organization Schedules for Clinical Assessment in Neuropsychiatry to establish the psychiatric diagnosis.
