The effects of deposition cycles on the structural and optical properties of lead tin sulphide (PbSnS) thin films have been described. Successive ionic layer adsorption and reaction (SILAR) method was used to deposit the ternary material on soda-lime substrates. In the present work, the PbSnS films were grown using lead nitrate, tin chloride dehydrate and thioacetamide solutions as sources of Pb, Sn and S, respectively. XRD measurements revealed that the deposited films were polycrystalline in nature with strong adherent to the substrates. The transmittance was found to be high in the near inf

Electropolymerized poly(o-ethoxyaniline) (POEA) nanostructured thin films were successfully deposited on indium tin oxide (ITO) substrate. The surface dynamic of the films was extensively investigated using morphological and multifractal parameters extracted from the atomic force microscopy (AFM). AFM topographical maps reveal surfaces with different morphologies as a function of the deposition cycles. The height parameters show that there is greater spatial vertical growth for films deposited with higher cycles of deposition. After five cycles of deposition occurs the formation of a more isot

Water scarcity has necessitated greater water reuse, utilization of poor-quality water, and operation of systems at higher cycles of concentration. High silica content make-up water is a major obstacle to cost-effective treatment programs for systems operating at higher cycles of concentration. The typical approach uses a base treatment program with an overlay or supplemental treatment, such as high polymers in combination with phosphonates, to control silica approaching 300 mg/L. However, this approach leads to very expensive treatments. This study presents a novel treatment program that inco

Abstract We have developed a non-destructive technique to observe Li in an electrode and metallic Li deposition on an anode using muonic x-rays. With high intent negative muon beam at J-PARC, we have attempted operando measurements of Li and metallic Li deposition in LIBs for the first time. Both increase and decrease of Li in a cathode during charging and discharging processes were observed. We also observed significant increase of muonic x-rays of Li with cycles, which may correspond to the degradation of charge capacity with the cycles.

Abstract The ca. 1.4 Ga Velkerri and Xiamaling Formations, in Australia and the north China craton, respectively, are both carbonaceous shale deposits that record a prominent euxinic interval and were intruded by ca. 1.3 Ga dolerite sills. These similarities raise the possibility that these two units correlate, which would suggest the occurrence of widespread euxinia, organic carbon burial, and source rock deposition. Paleomagnetic data are consistent with Australia and the north China craton being neighbors in the supercontinent Nuna and thus permit deposition in a single large basin, and the

Abstract Wire arc additive manufacturing (WAAM) is a notably promising direct energy deposition (DED) technology for the production of large scale metallic components of various shapes without the need for complex tooling, moulds, or dies. The main advantages of this technology include high material efficiency, lead time reductions, a high deposition rate, and low production costs. WAAM offers numerous benefits for a wide range of metallic materials, like aluminum, copper, and magnesium, and their alloys.

In this paper, feasibility of aluminium deposition on inner wall of pipes by atomic layer deposition was studied. Firstly, by solving kinetics equation of gas adsorption on the pipe inner wall, the time for the reactant to reach saturated adsorption on the wall was calculated. Secondly, according to the aluminium crystal structure, the thickness of each deposition cycle was obtained. Finally, the minimum aluminium thickness and number of atomic layer deposition cycles that can meet electromagnetic requirement of wave guide was calculated.

Reaction mechanisms during the growth of multinary compounds by atomic layer deposition can be complex, especially for sulfide materials. For instance, the deposition of copper indium disulfide (CuInS2) shows a non-direct correlation between the cycle ratio, the growth per cycle of each binary growth cycles, i.e., CuxS and In2S3, and the film composition. This evidences side reactions that compete with the direct Atomic Layer Deposition (ALD) growth reactions and makes the deposition of large films very challenging.

The wires were coated using atomic layer deposition (ALD) with 100 ALD cycles.
