The production of metal hydrides in vapour phase is one of the problems which makes their spectroscopic investigation at high resolution difficult. The molecular densities are usually low and the absorption is often increased by the use of multipass cells or intracavity setups. In this contribution a discharge tube with coaxial geometry is investigated, which is able to produce relatively high ...

Invited for this month's cover is the group of Prof. F. Matthias Bickelhaupt. The cover picture illustrates the authors' quantum chemical finding that π electrons can significantly bend otherwise linear d(10)-ML2 complexes through backbonding. For more details, see the Full Paper on p. 106 ff.

With the continuous exploration of 2D transition metal dichalcogenides (TMDs), novel high-performance devices based on the remarkable electronic and optoelectronic natures of 2D TMDs are increasingly emerging. As fresh blood of 2D TMD family, anisotropic MTe2 and ReX2 (M = Mo, W, and X = S, Se) have drawn increasing attention owing to their low-symmetry structures and charming properties of mec...

Continuous flow hydrothermal synthesis offers a cheap, green and highly scalable route for the preparation of inorganic nanomaterials which has predominantly been applied to metal oxide based materials. In this work we report the first continuous flow hydrothermal synthesis of metal sulphide nanomaterials. A wide range of binary metal sulphides, ZnS, CdS, PbS, CuS, Fe(1-x)S and Bi2S3, have been...

High-pressure metal hydride vehicular hydrogen storage systems can offer good overall gravimetric and volumetric hydrogen densities. Enhanced heat transfer techniques will be essential to achieve established goals for tank filling times. A numerical model is developed to simulate the hydrogen filling process of a subscale high-pressure metal hydride (Ti1.1CrMn) system. The model is validated by...

we propose a new generation of unbiased (bias-free) antenna-less cw thz photomixer emitters array made of asymmetric msm gratings with subwavelength pitch, operating in optical near-field regime. we take advantage of the size effects in near-field optics and electrostatics to demonstrate the possibility of enhancing the thz power by four orders of magnitude, as compared with a similar array of ...

در این پژوهش به مطالعه خواص الکترونی سیم مولکولی مدل au/cnt/au به ازاء طولها و قطر های مختلف از نانو لوله کربنی (cnt) نیمه هادی (نوع زیگ-زاگ) و شکل های مختلفی از طلا پرداخته ایم. بصورت نظری رسانایی وابسته به طول و قطر نانو لوله کربنی در سیم های مولکولی، بر اساس مدل سه بعدی محدود به سایز مورد بررسی قرار گرفت. واضح است که وابستگی رسانایی به طول زنجیره، حتی در الکترون های بی واکنش هم تفاوت هایی از...
