Process Simulation and Economic Analysis of Pre-combustion CO2 Capture With Deep Eutectic Solvents

The purpose of this paper is to identify firstly the most important solvent characteristics in the CO2 capture process and secondly to determine how they contribute to the total cost of CO2 separation and analyze the economic feasibility of current deep eutectic solvents (DESs) in literature. A rate-based modeling approach was adopted to simulate pre-combustion CO2 capture. The effects of the flow model and the number of segments were investigated for the Selexol process. Different mass transfer correlations due to Bravo et al. (1985), Billet and Schultes (1993) and Hanley and Chen (2012) were adopted for the rate-based models and compared with the equilibrium modelling approach. Subsequently, property and process models were developed for a mixture of decanoic acid and menthol, in equal quantities. A physical property study was conducted with this DES. The CO2 solubility is found to be very important in all rate-based models, as expected, but properties such as the surface tension, thermal conductivity, heat capacity and volatility had a minor influence on the absorption performance. The solvent viscosity strongly affects the mass transfer rate when using the Hanley and Chen (2012) correlations, whereas it plays only a small role in the other two sets of correlations. Using a high CO2 solubility as criterion, two mixtures of allyl triphenylphosphonium bromide (ATPPB) and diethylene glycol (DEG) were screened out from literature. The conventional Selexol process was set as the benchmark for the evaluation of the performances of these DESs. The optimum capture cost for Selexol process is 27.22, 26.66 and 30.84 $(2018)/tonne CO2 for the adopted correlations, respectively. When employing two of the three studied mass transfer correlations, the estimated process costs for a capture process using this DES can be similar to the costs of the Selexol process. However, when the liquid viscosity strongly affects the mass transfer rate, as is the case when using the Hanley and Chen (2012) correlations, the Selexol process remains more economical. This strongly indicates the need for further experimental and modelling studies on mass transfer rates in absorption columns (with higher viscosity liquids) to help directing the development of suitable DESs for pre-combustion CO2 capture.

Molecularly imprinted photoelectrochemical sensor for carcinoembryonic antigen based on polymerized ionic liquid hydrogel and hollow gold nanoballs/MoSe2 nanosheets

Using carcinoembryonic antigen (CEA) imprinted polymerized ionic liquid hydrogel as a recognition element and hollow gold nanoballs/MoSe2 nanosheets as a photoactive element, a photoelectrochemical (PEC) sensing platform was successfully fabricated. To accomplish the imprinted process under room temperature to maintain the biological activity and the configuration of CEA, and thus to improve the sensing performances, 3-{[{4-N,N-Bis[(carbamoyl)ethylmethacrylate]butyl}((carbamoyl)amino)ethyl methacrylate] -propyl}-1-ethenyl-1H-imidazol-3-ium bromide (BCCPEimBr) ionic liquid was synthesized. By using BCCPEimBr ionic liquid as the functional monomer, CEA as the template, a molecularly imprinted hydrogel film was prepared on a hollow gold nanoballs/MoSe2 nanosheets modified glassy carbon electrode surface. After removing the template, a CEA imprinted photoelectrochemical sensor was successfully fabricated. The imprinted PEC sensor shows good selectivity, sensitivity and stability towards CEA, produces a linear response in the concentration range from 0.05 to 5.0 ng mL(-1) and shows a detection limit of 11.2 pg mL(-1) (S/N = 3) under the optimized conditions. The imprinted PEC sensor was used to determine CEA in clinical human serum samples accurately. The procedure for the imprinted PEC sensing platform can be used for other biomolecules just by substituting the template. (C) 2019 Elsevier B.V. All rights reserved.

MicroRNA-485-5p reduces keratinocyte proliferation and migration by regulating ITGA5 expression in skin wound healing

Purpose: To determine the effect of miR-485-5p on keratinocyte proliferation and migration. Methods: Human primary keratinocytes (HaCaT cells) were treated with different concentrations of transforming growth factor-beta 1 (TGF)-beta 1. miR-485-5p expression levels were determined using quantitative reverse transcription-polymerase chain reaction (qRT-PCR). MTT (3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide) and wound healing assays were performed to investigate the regulatory effects of miR-485-5p on cell viability and migration of HaCaT cells. Downstream target gene expression of miR-485-5p was determined using a luciferase activity assay. Results: In HaCaT cells, miR-485-5p was time- and dose-dependently downregulated by TGF-beta 1 treatment (p < 0.05). Forced expression of miR-485-5p decreased cell viability and migration of HaCaT cells (p < 0.05). Knockdown of miR-485-5p enhanced HaCaT cell viability and migration. Integrin subunit alpha-5 (ITGA5) was predicted and verified to be a downstream target of miR-485-5p in HaCaT cells. Overexpression of ITGA5 attenuated the miR-485-5p-induced decrease of HaCaT cell viability and migration (p < 0.05). Conclusion: MiR-485-5p reduces cell proliferation and migration of keratinocytes through the regulation of ITGA5. This mechanism provides a potential therapeutic strategy for skin wound healing. The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

Metal-Loaded Carbonated Mesoporous Calcium Silicates: Synthesis, Characterization, and Application for Diclofenac Removal from Water

In this study, we developed a simple synthesis method of carbonated mesoporous calcium silicate (MCS) materials loaded with iron (Fe-MCS), cerium (Ce-MCS), and iron and cerium (FeCe-MCS) using cetyltrimethylammonium bromide as a template. Such materials were characterized by different advanced techniques-X-ray diffraction analysis, nitrogen physisorption measurement, transmission electron microscopy, scanning electron microscopy with energy-dispersive spectroscopy, X-ray photoelectron spectroscopy, and Fourier-transform infrared spectroscopy. They were examined by adsorption isotherms and wet oxidation to explore their maximum adsorption capacity and catalytic activity toward diclofenac (DCF) in solution, respectively. Results indicated that the advantageous properties of metal-loaded MCS samples were relatively similar to pristine MCS, suggesting that the basic properties of carbonated MCS were properly maintained after the loading process. Their specific surface area and total pore volume ranged 468-634 m(2)/g and 0.761.15 cm(3)/g, respectively. The Langmuir maximum adsorption capacity of DCF by the prepared adsorbents followed the increasing order: MCS (11.8 mg/g) < Fe-MCS (13.8 mg/g) < Ce-MCS (14.7 mg/g) < FeCe-MCS (23.7 mg/g). The adsorption mechanism mainly involved pore filling, hydrogen bonding, and pi-pi interaction. The Fe-MCS catalyst exhibited higher DCF degradation efficiency and rate constant under wet oxidation than the other prepared catalysts. Therefore, the MCS loaded with iron can be regarded as a promising adsorbent and potential catalyst for the efficient removal of DCF drug from water media. Interested yet?

Efficient electronic coupling and heterogeneous charge transport of zero-dimensional Cs4PbBr6 perovskite emitters

Organic and/or inorganic halide perovskites have become a new class of optoelectronic materials by virtue of excellent attractive physical and chemical characteristics. In this context, the zero-dimensional (0-D) cesium lead bromide (Cs4PbBr6) perovskite with outstanding photoluminescence (PL) properties has been recognized as the most promising candidate. However, the electron transfer dynamics and electrochemical behaviors of Cs4PbBr6 emitters still remain unclear. Herein, we prepared the 0-D Cs4PbBr6 perovskite emitters and investigated the exciton transport and electrochemical dynamics by utilizing temperature-dependent transient photoluminescence (TRPL) and electrogenerated chemiluminescence (ECL) techniques, respectively. Stronger electronic coupling of Cs4PbBr6 emitters arises from the overlap of electronic wavefunctions, indicating the increased possibility for the generation of electrochemiluminescence. Through the determination of the diffusion coefficient and electron-transfer rate by using an electrochemical method, we confirm that effective heterogeneous charge transfer at the interface of the electrode and electrolyte results in red-shifted ECL emission in the presence of benzoyl peroxide (BPO) as the co-reactant. The development of zero-dimensional perovskite emitters opens up a new avenue in the field of emerging optoelectronic and biosensing technologies, including but not limited to ECL devices, ECL immunoassays, organic light-emitting diodes, light-emitting electrochemical cells, and other bio-related detections.

Multi-targeted potential of Pittosporum senacia Putt.: HPLC-ESI-MSn analysis, in silico docking, DNA protection, antimicrobial, enzyme inhibition, anticancer and apoptotic activity

Pittosporum senacia (PS) Putt. (Pittosporaceae), indigenous to the Mascarene Islands, is a common ingredient in traditional medicines. However, there is currently a dearth of studies to validate some of these traditional claims. Given the broad traditional uses of PS against several diseases, we aimed to provide a comprehensive insight into the biological and chemical profile of P. senacia. The antioxidant, enzyme inhibitory activity, anticancer, and phytochemical composition of the methanolic extract of P. senacia leaf extracts were studied. The possible interaction and binding mode of the most abundant phytochemicals were studied via in silico docking experiments on tyrosinase and alpha-glucosidase. The mechanism behind the cytotoxic property of P. senacia extract for MDA-MB-231 was also examined using different methods including 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) cell viability test checking apoptosis-associated genes, and wound healing assays. Twenty-six compounds were identified, of which caffeoylquinic acid derivatives, ferulic acid derivative, cinnamoylquinic acid derivative and two other polyphenols (oleuropeine and isoramnetin glucoside) being abundant, have been tested using in silico studies, against alpha-glucosidase and tyrosinase. The extract (IC50 = 118.8 mu g/ml) exhibited time and dose dependent anti-proliferative effect on human breast cancer cell line, MDA-MB-231. According to the expression profile of apoptosis inhibitors and apoptosis promoters genes, expression of Bar and Bak genes were significantly increased compared to Bcl-2 and Birc5 genes. Based on wound healing analysis, cell migration was inhibited after the application of the plant extract. The present findings suggested that PS might be a good candidate as sources of bioactive compounds for designing functional applications.

Dual cross-linked polymer electrolyte membranes based on poly(aryl ether ketone) and poly(styrene-vinylimidazole-divinylbenzene) for high temperature proton exchange membrane fuel cells

One critical issue to phosphoric acid (PA) doped high-temperature proton exchange membranes (HT-PEMs) is to balance the proton conductivity and mechanical properties for overall application performance in fuel cells. Addressing the issue, we prepare durable HT-PEMs having the dual crosslinking structure by employing poly (vinylimidazole-divinylbenzene-styrene) (poly(VIm-DVB-St)) copolymer as a crosslinker and using the poly (aromatic ether ketone) (PAEK) polymer containing four methyl groups as the host membrane matrix. The imidazole groups of poly(VIm-DVB-St) react with benzyl bromide groups of brominated PAEK for both the primary cross-linking network and high PA doping. The divinylbenzene crosslinked poly (styrene-co-vinylimidazole) network generates the secondary cross-linking structure. The formed reticular polymer chain structure brings on low swelling and high mechanical strength of the HT-PEMs. The fuel cell based on the acid doped PAEK41-85%VIm/233.0 PA shows a H-2-air fuel cell peak power density of 306 mW cm(-2) at 200 degrees C without back pressure, and a low degradation rate of 3.9 x 10(-5) V h(-1) during a period of 600 h under a constant current density of 200 mA cm(-2) at 160 degrees C.

Innovative composite sorbent for thermal energy storage based on a SrBr2 center dot 6H(2)O filled silicone composite foam

This paper reports about the first experimental activity on a composite material for thermal energy storage, based on a SrBr2 center dot 6H(2)O filled silicone foam. The morphological and thermal features of the composite with different salt content (i.e. between 40 wt.% and 70 wt.%) were investigated. The dehydration behavior was studied by thermo-gravimetric analysis. Furthermore, scanning electron and 3D optical microscopy were used to compare the cellular microstructure of the composite foams. The synthesized foams are characterized by a well-interconnected cellular structure with a three-dimensional porous network. This, together with the high permeability to water vapor of the matrix favors water vapor diffusion and allows the reaction of all the salt embedded in the matrix. The main advantages of the composite material were analyzed and compared to other composites in literature. Since the production process, especially for higher salt content, seemed not sufficiently effective, causing a reduced foaming ration and lower ability to incorporate the salt hydrate, possible improvements were proposed and discussed.

Spontaneous epoxidation of styrene catalyzed by flower-like NiO nanoparticles under ambient conditions

Flower-like NiO microspheres with an average size of 3 mu mand nanoflakes size 10-100 nm were synthesized by surfactant-assisted chemical precipitation method, using Ni(CH3CO2)(2)center dot 4H(2)O as a nickel source, diethanolamine as a complexing agent, and cetyltrimethylammonium bromide as a surfactant. The obtain material was characterized by SEM, EDX, HRTEM, XRD, and TGA. The obtained results confirmed the formation of highly ordered flower-like NiO nanoparticles. The catalytic activity of the obtained material was evaluated in the epoxidation reaction of styrene u n d e r a m b i e n t c o n d i t i o n s, us ing m e t a chloroperoxybenzoic acid (m-CPBA) as an oxidant. The obtained results revealed an immediate conversion of styrene to styrene oxide, with high conversion (87%), medium selectivity (65%), and high turnover-frequency (TOF) (243 s(-1)). However, when bulk NiO was applied only 62% conversion with 68% selectivity and TOF = 174 s(-1) were obtained. Furthermore, this catalyst is was easily separable and recyclable. Moreover, a possible reaction mechanism is also proposed.
