By combining ab initio calculations and experiments, we demonstrate how the band gap of the transition metal trichalcogenide TiS3 can be modified by inducing tensile or compressive strain. In addition, using our calculations, we predicted that the material would exhibit a transition from a direct to an indirect band gap upon application of a compressive strain in the direction of easy electrical transport. The ability to control the band gap and its nature could have a significant impact on the use of TiS3 for optical applications. We go on to verify our prediction via optical absorption experiments that demonstrate a band gap increase of up to 9% （from 0.99 to 1.08 eV） upon application of tensile stress along the easy transport direction.

AIM： To assess the prevalence of portal hypertension （PH） related colorectal lesions in liver transplant candidates, and to evaluate its association with the severity of PH. METHODS： Between October 2004 and December 2005, colonoscopy was performed in 92 cirrhotic liver transplant candidates. We described the lesions resulting from colorectal PH and their association with the grade of PH in 77 patients who underwent measurement of hepatic venous pressure gradient （HVPG）. RESULTS： Mean age was 55 years and 80.7% of patients were men. The main etiology of cirrhosis wasalcoholism （45.5%）. Portal hypertensive colopathy （PHC） was found in 23.9%, colonic varices in 7.6% and polyps in 38% of patients （adenomatous type 65.2%）. One asymptomatic patient had a well-differentiated adenocarcinoma. The manifestations of colorectal PH were not associated with the etiology of liver disease or with the Child-Pugh grade. Ninety percent of patients with colopathy presented with gastroesophageal varices （GEV）, and 27.5% of patients with GEV presented with colopathy （P = 0.12）. A relationship between higher values of HVPG and presence of colopathy was observed （19.9：1：6.2 mmHg vs 16.8 ± 5.4 mmHg, P = 0.045）, but not with the grade of colopathy （P = 0.13）. Preneoplastic polyps and neoplasm （P = 0.02） and spontaneous bacterial peritonitis （P = 0.006） were more prevalent in patients with colopathy. We did not observe any association between previous β-blocker therapy and the presence of colorectal portal hypertensive vasculopathy. CONCLUSION： PHC is common in cirrhotic liver transplant candidates and is associated with higher portal pressure.

The isolation of the first two-dimensional material, graphene-a monolayer of carbon atoms arranged in a hexagonal lattice-opened new exciting opportunities in the field of condensed matter physics and materials. Its isolation and subsequent studies demonstrated that it was possible to obtain sheets of atomically thin crystals and that these were stable, and they also began to show its outstanding properties, thus opening the door to a whole new family of materials, known as two-dimensional materials or 2D materials. The great interest in different 2D materials is motivated by the variety of properties they show, being candidates for numerous ***, the combination of 2D crystals allows the assembly of composite, on-demand materials, known as van der Waals heterostructures, which take advantage of the properties of those materials to create functionalities that otherwise would not be accessible. For example, the combination of 2D materials, which can be done with high precision, is opening up opportunities for the study of new challenges in fundamental physics and novel applications. Here we review the latest fundamental discoveries in the area of 2D materials and offer a perspective on the future of the field.

Effect of Exogenous Melatonin on Seed Germination and Seedling Growth in Melon(Cucumis melo L.) Under Salt Stress

引用

Horticultural Plant Journal 2019年第2期5卷 79-87页

作者： José Luis Casta?ares Carlos Alberto Bouzo Plant Physiology Laboratory Department of Basic Sciences Universidad Nacional de Luján Laboratory of Research in Physiology and Plant Molecular Biology Facultad de Ciencias Agrarias Universidad Nacional del Litoral

An investigation was carried out to evaluate the effect of different application forms and concentrations of melatonin on germination and initial growth of melon plants in several different salinity conditions. We evaluated germination percentage and growth of seedlings and measured total chlorophyll content, relative electrolyte leakage, peroxidase activity, root viability, proline concentration, relative water content,Na^+/K^+ratio in green parts and K^+leakage from roots. Seed germination percentage under salt stress increased with treatments of 10 and50 μmol·L^(-1) melatonin. Seed treatment and plant watering with melatonin at 50 μmol·L^(-1) improved growth parameters and plants showed higher chlorophyll content as well as better biochemical parameters than non-treated plants. Results suggest that melatonin can alleviate the effect of salt stress during seed germination and first stages of plant development.

Hydrogen Storage by Titanium Based Sulfides： Nanoribbons （TiS3） and Nanoplates （TiS2）

引用

Journal of Electrical Engineering 2015年第1期3卷 24-29页

作者： Mariam Barawi Eduardo Flores Marine Pomhieu Jose Ramon ares Fermin Cuevas Fabrice Leardini Isabel Jimenez Ferrer Carlos sanchez Mire Group Science Faculty Autonomous University of Madrid Madrid 28012 Spain CEA LITEN Hydrogen Biomass Thermal Department Grenoble F-38054 France CMTR/ICMPE/CNRS-UPEC UMR7182 2-8 rue Henri Dunant Thiais Cedex 94320 France

Nowadays, finding cheap and non-toxic materials able to reversibly store high amounts of hydrogen is a challenge in the renewable energy field. Metal sulfides seem to be promising candidates to this purpose. Titanium sulfides are reported to be particularly interesting but their ability to store hydrogen remains unclear. In this work, titanium based sulfides TiS2 and TiS3 with two-dimensional nanostructures have been synthesized by solid-gas reaction between titanium powder and sulfur at temperatures between 500-600℃. The morphology and crystal structure of Ti-sulfides were characterized by SEM （scanning electronic microscopy） equipped with EDX （energy dispersion X-ray） and XRD （X-ray diffraction）, respectively. Their thermal stability was examined by TGA （thermal gravimetric analysis）. Their hydrogenation properties have been determined by manometric means using a Sieverts system and by DSC-HP （high-pressure differential scanning calorimetric）. Ti-sulfides hardly absorb/adsorb hydrogen for hydrogen pressures up to 80 bar and reaction temperatures up to 300℃.
