Assembly of the top-down graphene units mostly results in 3D porous structure with randomly organized pores. The direct bottom-up synthesis of macroscopic 2D graphene sheets with organized pores are long sought in materials chemistry field, but rarely achieved. Herein, we present a self-catalysis-assisted bottom-up route using L-glutamic acid and iron chloride as starting materials for the fabrication of the millimeter-sized few-layer graphene sheets with aligned porous channels parallel to the 2D direction. The amino- and carboxyl-functional groups in L-glutamic acid can coordinate with iron cations, thus allowing an atomic dispersion of iron cations. The pyrolysis thus initiated the growth of graphene catalyzed by in situ generated iron nanoparticles, and a dynamic flow of iron nanoparticles eventually led to the formation of millimeter-sized few-layer graphene sheets with aligned channels (60-85 nm in diameter). Used as anodes in lithium-ion batteries, these graphene sheets showed a good rate capability (142 mA h g(-1) at 2 A g(-1)) and high capacity retention of 93% at 2 A g(-1) after 1200 cycles. Kinetic analysis revealed that lithium ions storage was dominated by diffusion behavior and capacitive behavior together, in that graphene sheets with aligned channels could accelerate electron transfer and shorten lithium ions transport pathway. This work provides a novel approach to prepare unique porous graphene materials with specific structure for energy storage.

Acetonitrile recovery from a residual aqueous solution was performed by different techniques. Particularly, a residual acetonitrile-water solution used in high-performance liquid chromatography analyses at the School of Pharmaceutical Sciences of the University of Sao Paulo was investigated with the aim to identify the most feasible way to treat such a waste and recover acetonitrile within its dependencies. Three procedures were set up and tested, which consisted of different combinations of well-known separation techniques, such as fractional distillation, cooling, salting-out, and sugaring-out. Cooling followed by distillation and subsequent addition of calcium chloride allowed to recover the highest amount of acetonitrile with a purity greater than 95 %.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 874-42-0. COA of Formula: https://www.ambeed.com/products/874-42-0.html.

Magnesium hydride (MgH2) is one of the competitive hydrogen storage materials on account of abundant reserves and high hydrogen content. The hydrolysis of MgH2 is an ideal and controllable chemical hydrogen generation process. However, the hydrolyzed product of MgH2 is a passivation layer on the surface of the magnesium hydride, which will make the reaction continuity worse and reduce the rate of hydrogen release. In this work, hydrogen generation is controllably achieved by regulating the change of the surface tension value in the hydrolysis, a variety of surfactants were systematically investigated for the effect of the hydrolysis of MgH2 In the meantime, the passivation layer of MgH2 was observed by scanning electron microscope (SEM), and the surface tension value of the solution with different surfactants were monitored, investing the mechanism of hydrolysis adding different surfactants. Results show that different surfactants have different effects on hydrogen generation. The hydrogen generation capacity from high to low is as follows: tetrapropylammonium bromide (TPABr), sodium dodecyl benzene sulfonate (SDBS), Ecosol 507, octadecyl trimethyl ammonium chloride (OTAC), sodium alcohol ether sulfate (AES), and fatty methyl ester sulfonate (FMES-70). When the ratio of MgH2 to TPABr was 5 : 1, the hydrogen generation was increased by 52% and 28.3%, respectively, at the time of 100 s and 300 s. When hydrolysis time exceeds 80 s, the hydrogen generation with AES and FMES-70 began to decrease; it was reduced by more than 20% at the time of 300 s. SEM reveals that surfactants can affect the crystalline arrangement of Mg(OH)(2) and make the passivation layer three-dimensionally layered providing channels for H2O molecules to react with MgH2.

The late consolidation of an aversive memory is promoted by VTA dopamine release in the dorsal hippocampus

The hippocampus has been implicated in the processing and storage of aversive memories but the precise mechanisms by which these memories persist in time remain elusive. We have demonstrated that dopaminergic neurotransmission in the dorsal hippocampus regulates the long-term storage of both appetitive and aversive memories at a critical time point known as late consolidation (12 hr after the learning experience). This modulation appears to have opposite effects depending on the valence of the stimuli, with hippocampal dopamine release peaking immediately and 13-17 hr after a rewarding experience. Here, we determined the release pattern of hippocampal dopamine following an aversive experience, in order to better understand this opposite modulation process. We observed significant increases in dopamine levels at several times (6-8, 11-12, and 15 hr) after subjecting rats to a conditioned place aversion (CPA) task with the aversive agent lithium chloride (LiCl). Early pharmacological blockade of hippocampal DA receptors impaired CPA memory consolidation. In addition and consistent with previous findings showing that late post-training infusions of dopaminergic agents into the hippocampus modulate the long-term storage of aversive memories, we found that the photostimulation of dopaminergic VTA fibers in the dorsal hippocampus 11-12 hr after CPA training was enough to transform a short-lasting long-term memory into a long-lasting one. The fact that the persistence of an aversive memory can still be affected several hours after the learning experience opens new avenues to develop behavioral and pharmacological strategies for the treatment of a variety of mental disorders.

C-60-based chemical labeling strategy for the determination of polyamines in biological samples using matrix-assisted laser desorption/ionization mass spectrometry

Bioactive polyamines play important roles in many biological processes such as gene expression, cell growth, protein synthesis, and signal transduction. Accurate determination of polyamines is helpful for studying their biological functions. Herein, a C-60-based chemical labeling strategy was proposed for the determination of polyamines (putrescine, cadaverine, spermidine, and spermine) in biological samples using matrix-assisted laser desorption/ionization mass spectrometry (MALDI MS). An N-hydroxysuccinimide ester functionalized C-60 (NHS-C-60) was used as a labeling reagent and the m/z of the labeled polyamines reached up to more than 900 Da, which avoided matrix interferences in the low m/z region. In addition, as NHS-C-60 derivatives, mono- and bis-substituted polyamines were produced simultaneously, which benefited the qualitative analysis of polyamines. The analytical method was validated using NHS-C(60)labeled polyamines in cells and mice feces samples. Good linearities were obtained with correlation coefficients ranging from 0.9786 to 0.9982. The limits of quantification were in the range of 0.68-1.48 pmol. Good reproducibility and reliability of our proposed method were confirmed by intra- and inter-day precisions ranged from 2.8 to 16.6%, and the recoveries ranged between 81.8 and 119.9%. Finally, the proposed method was applied to determine polyamines in cells and mice feces. Three polyamines were detected in the cells, and the contents of cadaverine and spermidine in the feces of high-fat diet mice were found to be significantly lower than those in the normal diet mice. The results show that the proposed NHS-C-60 labeling coupled with MALDI MS strategy is suitable for the determination of polyamines in biological samples.

Studies on the surface properties and microaggregates of cationic/anionic surfactant mixtures based on sulfonate gemini surfactant

The surface properties and the microaggregates of a sulfonate gemini surfactant 12-bis(N-dodecyl-N-propane sulfonate sodium)-ethane (SGS12) and conventional cationic surfactant hexadecyl trimethyl ammonium bromide (CTAB) mixtures were studied. The critical micelle concentration (CMC) values of SGS12, CTAB, and SGS12/CTAB mixtures (1:1) were 0.0045, 0.89 and 0.0031 mmol.dm(-3), respectively. By changing the molar ratios of SGS12 to CTAB, the transitions between micelles and vesicles were observed. When n(SGS12):n(CTAB) = 4:6, the size of surfactant aggregates increased abruptly to 68.06 nm, and a pale blue opalescence appeared, which was consistent with the size and optical characteristics of the vesicles. The hydrodynamic diameter (D-H) of all surfactant aggregates increases with the increase of temperature from 35 degrees C to 50 degrees C. Especially at n(SGS12):n(CTAB) = 6:4, we observed a temperature-induced transition from micelles to vesicles. We also investigated the effects of 1-propanol on the SGS12/CTAB precipitate. At n(SGS12):n(CTAB) = 4:6, the addition of 1-propanol led to the precipitate -> vesicles -> micelles transition. Moreover, the addition of NaCl increased the aggregate size of the SGS12/CTAB mixtures, and we observed the light blue opalescence. The addition of NaCl induced the formation of vesicles. As a result, the SGS12/CTAB mixtures have more excellent surface activity than either component. By changing the composition, temperature, the concentration of salt, and the volume fraction of alcohol, the transition of precipitation -> vesicles -> micelles can be achieved.

Effects of thiosulfate and dissolved oxygen on crevice corrosion of Alloy 690 in high-temperature chloride solution

The crevice corrosion behavior of Alloy 690 was investigated in high-temperature chloride solution containing different concentrations of thiosulfate (S2O32-) and dissolved oxygen (DO). The S2O32- inhibited corrosion of Alloy 690 through consuming oxygen in aerated chloride solution. In deaerated chloride solution, the S2O32- was reduced to S degrees and S-2 and subsequently incorporated into the oxide films, which promoted the pitting corrosion at locations of both TiN inclusions and matrix inside the crevice during the crevice corrosion as well as influenced the composition and thickness of the oxide films. The effect mechanisms of S2O32- and DO on crevice corrosion in high-temperature chloride solution are discussed.

Failure Analysis of Welded type 304 in Cooling Water Pipeline of District Heating System

Failure analysis on the welded type 304 pipe used for cooling water piping in the district heating primary side was conducted. Inorganic elements and bacteria in the cooling water and in corrosion products were analyzed, and the weldment was inspected by microscopy and a sensitization test. Corrosion damages were observed in the heat-affected zone, on weld defects such as incomplete fusion or excessive penetration caused by improper welding, or/and at the 6 o’clock position along the pipe axial direction. However, the level of concentration of chloride in the cooling water as low as 80 ppm has been reported to be not enough for even a sensitized type 304 steel, meaning that the additional corrosive factor was required for these corrosion damages. The factor leading to these corrosion damages was drawn to be the metabolisms of the types of bacteria, which is proved by the detection of proton, sulfur containing species, biofilms, and both bacteria and corrosion product analyses.

Validation of SMILES HCl profiles over a wide range from the stratosphere to the lower thermosphere

Hydrogen chloride (HCl) is the most abundant (more than 95 %) among inorganic chlorine compounds Cly in the upper stratosphere. The HCl molecule is observed to obtain long-term quantitative estimations of the total budget of the stratospheric chlorine compounds. In this study, we provided HCl vertical profiles at altitudes of 16-100 km using the Superconducting Submillimeter-Wave Limb-Emission Sounder (SMILES) from space. The HCl vertical profile from the upper troposphere to the lower thermosphere is reported for the first time from SMILES observations; the data quality is quantified by comparison with other measurements and via theoretical error analysis. We used the SMILES level-2 research product version 3.0.0. The period of the SMILES HCl observation was from 12 October 2009 to 21 April 2010, and the latitude coverage was 40 degrees S-65 degrees N. The average HCl vertical profile showed an increase with altitude up to the stratopause (similar to 45 km), approximately constant values between the stratopause and the upper mesosphere (similar to 80 km), and a decrease from the mesopause to the lower thermosphere (similar to 100 km). This behavior was observed in all latitude regions and reproduced by the Whole Atmosphere Community Climate Model in the specified dynamics configuration (SD-WACCM). We compared the SMILES HCl vertical profiles in the stratosphere and lower mesosphere with HCl profiles from Microwave Limb Sounder (MLS) on the Aura satellite, as well as from the Atmospheric Chemistry Experiment Fourier Transform Spectrometer (ACE-FTS) on SCISAT and the TErahertz and submillimeter LImb Sounder (TELIS) (balloon borne). The TELIS observations were performed using the superconductive limb emission technique, as used by SMILES. The globally averaged vertical HCl profiles of SMILES agreed well with those of MLS and ACE-FTS within 0.25 and 0.2 ppbv between 20 and 40 km (within 10% between 30 and 40 km; there is a larger discrepancy below 30 km), respectively. The SMILES HCl concentration was smaller than those of MLS and ACE-FTS as the altitude increased from 40 km, and the difference was approximately 0.4-0.5 ppbv (12 %-15 %) at 50-60 km. The difference between SMILES and TELIS HCl observations was about 0.3 ppbv in the polar winter region between 20 and 34 km, except near 26 km. SMILES HCl error sources that may cause discrepancies with the other observations are investigated by a theoretical error analysis. We calculated errors caused by the uncertainties of spectroscopic parameters, instrument functions, and atmospheric temperature profiles. The Jacobian for the temperature explains the negative bias of the SMILES HCl concentrations at 50-60 km.
