Gamma-phase Zn-Ni alloy deposition by pulse-electroplating from a modified deep eutectic solution

This article describes the electroplating of Zn-Ni alloy from a modified deep eutectic solvent (DES), a mixture of choline chloride (ChCl) and ethylene glycol (EG) commonly known by its commercial name Ethaline. In this study the Ethaline was modified with propylene carbonate (PC) to decrease the solution viscosity. Boric acid was also used as an additive to improve surface finish and adhesion. The modifications were shown to increase the reduction rate of metal ions through improved mass transport and also to improve the quality of finish (morphology and interfacial adhesion) of the coating. We demonstrate that it is possible to produce dense, thick and adherent coatings of a y-phase Zn-Ni alloy with 81-85% Zn on mild steel substrates using either potentiostatic deposition or controlled current pulse-plating techniques. Mild steel is a typical substrate for a sacrificial anti-corrosion coating used in many applications where the alloy serves to protect the steel from corrosion in harsh environments.

Corrosion performance of hot-dip galvanized zinc-aluminum coated steel rebars in comparison to the conventional pure zinc coated rebars in concrete environment

In this investigation zinc was alloyed with aluminum in order to improve the corrosion resistance of hot-dip galvanized coated steel rebars in contact with chloride-contaminated concrete. To rapidly assess the role of aluminum alloying in zinc, test panels in sheet form containing 10%, 15%, 20%, and 30% aluminum in zinc were prepared and evaluated in terms of their corrosion resistance via salt spray exposure tests. It was found that 10%Al-90%Zn (10AZ) provided the best results. Mild steel rebars were galvanized in 90% Zn-10%Al and 100%Zn (100Z) baths and their corrosion resistance performances when they were exposed to simulated concrete pore solution and embedded in mortars were examined. The10AZ-coated rebar showed superior corrosion resistance performance to the 100Z-coated rebar. Electrochemical impedance spectroscopy, DC polarization, scanning electron microscopy, Raman spectroscopy, and X-ray diffraction techniques were used to study the kinetics and corrosion mechanism of the coated rebars.

Improvement of thermal energy accumulation by incorporation of carbon nanomaterial into magnesium chloride hexahydrate and magnesium nitrate hexahydrate

Magnesium chloride hexahydrate and magnesium nitrate hexahydrate were tested for their thermal energy storage in a mixture with carbon materials. The graphite, graphene and zeolite-templated carbon replicas were used as a nucleating agent to supress supercooling. The addition of any type of carbon into magnesium chloride hexahydrate did not lead to a decrease in the supercooling and a significant decrease of the enthalpy of fusion and crystallisation was observed. The mixtures after cycling were apparently wet, indicating that some of the magnesium chloride was dissolved in its structural water. In the case of magnesium nitrate hexahydrate, the addition of carbon replicas of zeolite beta, mordenite or faujasite lead to a decrease in supercooling. Nevertheless, graphite and graphene provided the highest supercooling suppression from about 30 to 2.2 K within the fifty cycles. The thermal conductivity measurement of pressed tablets of magnesium nitrate hexahydrate with carbon materials at 2 MPa showed a significant increase of 9% and 15% for the addition of 3 mass% of graphene and 3 mass% of graphite, respectively. Mixing of magnesium nitrate hexahydrate with graphene or graphite improved heat transfer and significantly reduced unwanted supercooling, which is necessary for its use in thermal energy accumulation.

Pore characteristics of recycled aggregate concrete and its relationship with durability under complex environmental factors

The influences and mechanisms of single and coupled effect of carbonation, dry-wet cycles and freeze-thaw cycles on the durability of three types of recycled aggregate concrete were studied. The compressive strength, chloride ion migration coefficient and micro pore parameters of recycled aggregate concrete were tested. The results showed that carbonation and dry-wet cycles can improve the pore tortuosity and reduce the connectivity of pores, while freeze-thaw cycles, coupling of carbonation and freeze-thaw cycles, and coupling of carbonation, dry-wet cycles and freeze-thaw cycles can significantly reduce the pore tortuosity and deteriorate the pore structure. The key reason for durability failure of recycled aggregate concrete in a complex environment is the increase of large pore volume fraction. When more factors are coupled, the increase in the pore volume fraction is greater. Based on the pore tortuosity and large pore volume fraction, an integrated pore index was proposed, and a prediction model of compressive strength and chloride ion migration coefficient of recycled aggregate concrete under complex environmental factors was established, which provided the basis to evaluate and maintain the durability of recycled aggregate concrete.

Investigation of brain damage mechanism in middle cerebral artery occlusion/reperfusion rats based on i-TRAQ quantitative proteomics

The objective of this study is to analyze the differential protein expression profile in cerebral cortex of rats with middle cerebral ischemia/reperfusion (MCAO/R), explore the brain damage mechanism of MCAO/R at protein level, and provide experimental foundation for searching specific marker proteins of MCAO/R. Rat model of MCAO/R was established by modified suture-occluded method, and the model was evaluated by the results of brain 2,3,5-triphenyltetrazolium chloride (TTC) and hematoxylin-eosin (HE) staining. Cerebral cortex of rats from sham-operated group (Sham) and MCAO/R groups was used for FASP enzymatic hydrolysis, i-TRAQ quantitative labeling, and reverse-phase liquid chromatography purification and separation. Orbitrap Q Exactive mass spectrometry was used for qualitative and quantitative analyses of total differential protein expression profiles. MCAO/R rats had obvious cerebral infarction lesions, and the relative surface area of cerebral infarction was significantly different compared with sham rats, suggesting that MCAO/R rat model was successfully prepared. There were 199 significant difference proteins (MCAO/R vs Sham, p < 0.05, |fold change|> 1.2), including 104 up-regulated proteins and 95 down-regulated proteins. Gene ontology (GO) enrichment analysis showed that the up-regulated proteins were mainly concentrated in the biological processes of positive regulation of NF-kappa B transcription and I-kappa B kinase-NF-kappa B, etc. Down-regulated proteins were mainly concentrated in long-term synaptic potentiation, cellular response to DNA damage stimulus, etc. KEGG pathway analysis showed that the pathway involved in differential proteins includes oxidative phosphorylation, metabolic pathway, and Ras signaling pathway. Network analysis of differential proteins showed that Alb, ndufb5, ndufs7, ApoB, Cdc42, Ndufa3, Igf1r, P4hb, Mbp, Gc, Nme1, Akt2, and other proteins may play an important role in regulating oxidative stress, apoptosis, and inflammatory response in MCAO/R. Quantitative proteomics based on i-TRAQ labeling reveals the effect of inflammation and apoptosis in brain damage mechanism of MCAO/R. Besides, this research provide some experimental foundation for search and determination of potential therapeutic targets of MCAO/R.

Sustainable Conversion of Carbon Dioxide into Diverse Hydrocarbon Fuels via Molten Salt Electrolysis

In recent decades, the unlimited use of fossil fuels mostly for power generation has emitted a huge amount of carbon dioxide into the atmosphere which in return has led to global warming. Here we use green technology, the molten salt electrochemical system comprising titanium and mild steel as a cathode with a graphite anode, whereas molten carbonate (Li2CO3-Na2CO3-K2CO3; 43.5:31.5: 25 mol %), hydroxide (LiOH-NaOH; 27:73 and KOH-NaOH; 50:50 mol %), and chlorides (KCl-LiCl; 41-59 mol %) salts as electrolytes This study investigates the effect of temperature, feed gas ratio CO2/H2O, and use of different cathode materials on hydrocarbon product along with current efficiencies. Gas chromatography and mass spectroscopy have been applied to analyze the gas products. According to GC results, more specific results in terms of high molecular weight and long chain hydrocarbons were obtained using titanium cathodic material rather than mild steel. The results revealed that among all the electrolytes, molten carbonates at 1.5 V and 425 degrees C produced higher hydrocarbons as C7H16 while all other produced CH4. The optimum conditions for hydrocarbon formation and higher current efficiencies in the case of molten carbonates were found to be 500 degrees C under a molar ratio of CO2/H2O of 15.6. However, the current efficiencies do not change on increasing the temperature from 425 to 500 degrees C and is maintained at 99% under a molar ratio of CO2/H2O of 15.6. The total current efficiency of the entire cathodic product reduced clearly from 95 to 79% by increasing the temperature under a CO2/H2O ratio of 9.2 due to the reduction of hydrocarbon generation in this case, despite the formation of C7H16. Therefore, due to its fast electrolytic conversion rate and low cost (no use of catalyst) the practice of molten salts could be an encouraging and promising technology for future investigation for hydrocarbon fuel formation.

Bioaccessibility and cellular uptake by Caco-2 cells of carotenoids and chlorophylls from orange peels: A comparison between conventional and ionic liquid mediated extractions

Native extracts from orange peels were obtained by a conventional method using acetone and, an alternative method using ionic liquid (1-butyl-3-methylimidazolium chloride ([C(4)mim]Cl)). The bioaccessibilities and cellular uptakes of carotenoids, esters and chlorophylls were evaluated, since the influence of esterification on bioaccessibility and bioavailability is not well established. For this, the extracts were emulsified, submitted to in vitro simulated digestion model according to the INFOGEST protocol, followed by uptake by Caco-2 cells. Compounds were separated, identified and quantified by HPLC-PDA-MS/MS. After digestion, 22.0% and 26.2% of the total carotenoids and 45.9% and 68.7% of the chlorophylls were bioaccessible from the acetone and [C(4)mim]Cl extracts, respectively. The bioaccessibilities of xanthophylls and carotenes were significantly higher than those of the mono- and diesters. The uptake by Caco-2 cells varied from 130.2 to 131.9 ng/mg cell protein for total carotenoids and from 243.8 to 234.2 ng/mg cell protein for chlorophylls in the acetone and [C(4)mim]Cl extracts, respectively. In general, xanthophylls and esters were better absorbed than carotenes.

Chemoprotective effects of plasma derived from mice of different ages and genders on ovarian failure after cyclophosphamide treatment

Background Premature ovarian failure is one of the major side effects of chemotherapy drugs. Blood plasma contains several factors that might lead to the repair of different tissues. Objective The chemoprotective effects of plasma derived from mice with different ages and genders were assessed on ovarian tissue in cyclophosphamide-treated mice. Methods Forty-two adult female mice were divided into six groups as follows: (A) control; (B) 0.9% sodium chloride as vehicle; (C) cyclophosphamide; (D) cyclophosphamide + young male blood plasma; (E) cyclophosphamide + old male blood plasma; (F) cyclophosphamide + young female blood plasma. Ovarian failure was induced by injecting cyclophosphamide. On the 1st day, three groups received simultaneous injections of 150 mu L intraperitoneal and 70 mu L intravenous plasma derived from mice of different ages and genders. Each plasma type (150 mu L) was then injected intraperitoneally every other 3 days for 19 days. On day 21, the dissected ovaries were stained for stereological analysis. Also, estrogen and progesterone levels were measured. Results Cyclophosphamide had damaging effects on ovarian parameters and led to reduced hormone levels in comparison with the control group. However, treating with young female and, old male blood plasma, to a lesser degree, showed beneficial effects on the number of primordial follicles, pre-antral follicles, and granulosa cells. Also, these two treatments had protective effects on the volume of ovarian parameters as well as estrogen and progesterone levels in comparison with the cyclophosphamide group (P < 0.05). Conclusion Plasma derived from mice of different ages and genders can ameliorate premature ovarian failure against the adverse effects of cyclophosphamide. We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 707-36-8.

Microbial carbon use efficiency during plant residue decomposition: Integrating multi-enzyme stoichiometry and C balance approach

Accurate estimation of microbial carbon use efficiency (CUE) in soil is challenged by a high degree of genetic and environmental variability. Different methods vary in their estimates of soil microbial CUE giving the room to select the optimal method for a specific research task, while integrating different methods could improve our understanding of processes controlling CUE variability. Aiming to estimate CUE during plant residue decomposition in different soils, we applied the conventional C-balance method, single C-cycling enzymatic stoichiometry (SCE-STM) and newly proposed multi-C-cycling enzymatic stoichiometry (MCE-STM) methods. The STM approach derives CUE from elemental ratios of microbial biomass, substrate, and activities of C and nutrient (e.g. N) acquiring exoenzymes. The extended MCE-STM is a modification of the SCE-STM method, where we used the sum of three C-cycling enzymatic activities (beta-glucosidase (BGL), beta-D-cellobiohydrolase (BCL), beta-xylosidase (BXL)) as proxy for CUE calculation, instead of using a single C-acquiring enzyme (BGL). We hypothesized that MCE-STM provides a more reliable estimation of microbial CUE in soils amended with complex plant residues than the SCE-STM or the C balance approach. The comparison of methods was done in a laboratory incubation experiment, using two soils differing mainly in acidity level mixed with two specimen of plant residues differing in lignin (L) and polyphenol (PP) content. We anticipated a higher microbial CUE in less acidic (pH 5.1) soil amended with higher quality (lower (L + PP)/N) ratio)) plant residues than in more acidic (pH 4.3) soils amended with medium quality (higher (L + PP)/N ratio) plant residues, due to less energy investment in microbial metabolism in the former case. Microbial CUE estimations were completed at 7, 15, 30, 45 and 60 days. Lower CUE values (0.09-0.18) were recorded by MCE-STM as compare to those (0.24-0.47) obtained by C-balance and SCE-STM methods. Irrespective of applied CUE estimation methods, higher CUE was recorded in less acidic (pH 5.1) soil amended with residues of higher quality than the other three combinations. Microorganisms invested more energy to support growth in low pH soil in order to tolerate soil acidity, which, in turn, suppressed N-acquiring enzymatic activity and further decreased CUE. The modification of the MCE-STM method for CUE determination proposed in this work was capable to quantify the combined effect of soil pH and plant residue quality on efficiency of microbial metabolism. It, therefore, can be considered as viable alternative to the original stoichiometric modeling approach (SCE-STM).

Chondroitin sulfate as a green corrosion inhibitor for zinc in 26% ammonium chloride solution: Electrochemical and surface morphological analysis

In the present investigation, Chondroitin sulfate (CS) has been tested as green as a corrosion inhibitor for zinc carbon battery by using electrochemical impedance spectroscopy (EIS), electrochemical frequency trend modulation (EFTM) and potentiodynamic polarization (PDP) measurements. The calculated results suggest that inhibition efficiency is 98.9% at the optimum concentration (200 mg/L) in 26% NH4Cl solution at 308 K. The outcome of EIS indicates that the values of double-layer thickness increased as the CS concentration increased. EFTM suggests in the presence of CS corrosion rate and corrosion current decreased.PDP results reveal that the nature of CS adsorption is mixed with dominantly cathodic.CS adsorption on the zinc surface obeyed the ElA-wady adsorption isotherm model. The magnitude of Delta G(ads) supports the chemical nature of CS adsorption. The Scanning electron microscope (SEM), Energy dispersive X-ray spectroscopy (EDX), and X-ray photoelectron spectroscopy (XPS) study supports the presence of CS adsorbed film over the zinc surface.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 126764-17-8, you can contact me at any time and look forward to more communication. SDS of cas: 126764-17-8.
