Application of binary mixed surfactant additives in jet impingement cooling of a hot steel plate

The current research aims at investigating role of three different types of surfactants and their binary mixtures in producing high cooling rate during jet impingement on a hot steel plate (100 mmx100 mmx6 mm) having initial surface temperature above 900 degrees C. The surfactants used are Sodium dodecyl sulphate (anionic), cetyltrimethylammonium bromide (cationic) and Polysorbate 20 (Tween 20, non-ionic). The surface tension values of the surfactants and their mixed systems have been measured and it has been observed that the binary mixtures at specific compositions show lower surface tension compared to the pure ones mainly due to synergism. The cooling results reveal that the mixture of cationic and non-ionic surfactants produces the highest cooling rate amongst all the systems. The maximum cooling rate achieved is 182 degrees C/s for the composition of 25 vol% CTAB and 75 vol% Tween 20 and it is 67% more than that of pure water, 23% more compared to pure CTAB and and 7.7% more than that of pure Tween 20. Thus it can be seen that ultrafast cooling of a 6 mm thick steel plate can be achieved by using optimized concentrations of mixed surfactant additives and this leads to improvement of quality of steel produced.

Interaction of Polymer (Polyvinylpyrrolidone) with Azo Dye (Reactive Yellow): A Physicochemical Study

The influence of polymer, polyvinylpyrrolidone (PVP) on spectral properties of anionic azo dye, reactive yellow (RY) was investigated by UV-Vis spectroscopy in the temperature range of 298-313 K. The change in lambda(max) and absorbance indicated the presence of interaction between anionic dyes and polymer. The binding constant (K-b) of complexation was determined from the Benesi-Hildebrand plot. The K-b value increased with increasing dye concentrations and decreased with the rise of the temperature. The values of Delta G degrees for RY-PVP complexation were found to be negative and these negative values reduce with the enhancement of temperature which indicates that the binding process is more spontaneous at lower temperature. The negative values of Delta S degrees and negative values of Delta H degrees refer a process which is always enthalpy dominated. K-b values showed significant change with the change of pH. The K-b value enhances with the rise of the carbon chain length of the alcohol and reduces with increasing percentages of alcohol. The K-b value decreases at higher electrolyte concentrations and also with the increase of the size of the anion of the electrolyte. The removal of dye from the waste water by the interaction of dye with polymer in the presence of surfactant and salt of higher concentration has also been studied.

Solar-light-driven non-bias photoelectrolysis for bleach production from sea water and atmospheric oxygen

Non-bias production of a bleach aqueous solution was successfully demonstrated using a solar-driven photoelectrochemical cell consisting of a metal-oxide-semiconductor photoanode and Pt-based cathode. Both hypochlorous acid (HClO) and hypobromous acid (HBrO) were generated via two-electron oxidation of chloride (Cl-) and bromide (Br-) at the photoanode. The faradaic efficiency for HBrO production gradually improved with increasing Br- concentration in the electrolyte solution. Although a certain amount of HBrO was produced from a 1 mM NaBr aqueous solution, the co-existence of Cl- drastically enhanced the amount of HBrO produced from the dilute Br- solution. The use of a gas diffusion electrode (GDE) composed of a Pt/carbon catalyst layer for efficient 4-electron O-2 reduction enabled us to achieve the anodic photocurrent derived from the oxidation of Cl- and Br- under AM-1.5 simulated solar light irradiation. Moreover, we successfully accomplished convenient and simple production of aqueous bleach from artificial sea water via irradiating the photoanode with simulated solar light without applying external bias.

Anchoring ultrafine Co3O4 grains on reduced oxide graphene by dual-template nanocasting strategy for high-energy solid state supercapacitor

Co3O4-based materials are regarded as superior electrode candidates in various energy storage devices due to their high theoretical capacity. Unfortunately, the poor electronic conductivity and huge volume expansion hamper their widespread applications. Therefore, nano-processing and introducing conductive matrix can view as the necessary methods to make Co3O4-based materials better for an advanced supercapacitor electrode. Herein, a dual-template nanocasting technique is proposed to design the ultrafine Co3O4 grains highly-dispersed on the reduced oxide graphene nanosheets (Co3O4/rGO-C), in which cetyltrimethyl ammonium bromide and silicate species are hired as the ideal soft and hard template, respectively. Co3O4 grains with size <10 nm can expose more active sites and thus exert more redox activities to enhance the capacitive performance. In additional, similar to 4 nm moderate pores are obtained in Co3O4/rGO-C after the hard template removing, which provides more diffusion channels for ion/electron rapid transport and also effectively alleviates the volume expansion on cycling. Consequently, the Co3O4/rGO-C electrode exhibits a remarkable specific capacitance (709.1 F g(-1) at 1 A g(-1)) and long-term endurance (91.2% after 6000 cycles). Furthermore, an assembled solid-state asymmetric device of Co3O4/rGO-C parallel to rGO delivers a super-high energy-density of 48.2 Wh kg(-1) at 750.5 W kg(-1). The high energy-density assists two devices in lightning a red light-emitting diode for 340 s. These results evidence the nanocasting strategy as an efficient method to achieve the advanced electrode materials for energy storage devices. (C) 2019 Elsevier Ltd. All rights reserved.

MiR-148b suppressed non-small cell lung cancer progression via inhibiting ALCAM through the NF-kappa B signaling pathway

Background Non-small cell lung cancer (NSCLC) is the leading cause of cancer mortality worldwide. MiRNAs are recognized as important molecules in cancer biology. The aim of the study was to identify a novel biomarker miR-148b and its mechanism in the modulation of NSCLC progression. Methods The expressional level of miR-148b was analyzed by RT-PCR. The effect of miR-4317 on proliferation was evaluated through 3-(4,5-Dimethyl-2-thiazolyl)-2,5-diphenyl-2Htetrazolium bromide (MTT) assay. The effect of miR-148b on the metastasis of NSCLC was detected through transwell assays. The verification of the target of miR-148b was assessed by TargetScan and dual-luciferase reporter assay. The related proteins in this study were analyzed by western blot. Results Our findings confirmed that miR-148b was decreased in NSCLC and NSCLC patients with lower expression exhibited poorer overall survival (OS). Increasing miR-148b significantly repressed proliferation, invasion and migration. More importantly, activated leukocyte cell adhesion molecule (ALCAM) was determined as the direct target of miR-148b, and reintroduction of ALCAM attenuated miR-148b effect on the progress of NSCLC. In addition, NF-kappa B signaling pathway was modulated by miR-148b/ALCAM axis. Conclusions Our results indicated that miR-148b is able to suppress NSCLC growth and metastasis via targeting ALCAM through the NF-kappa B pathway. These findings provided new evidence that miR-148b serves as a potential biomarker and novel target for NSCLC treatment.
