Vanadium pentoxide and conducting polymers have promising applications in the field of elec. energy storage devices and combine flexible substance to form binder-free ternary electrodes, which would pave a new way for designing supercapacitors. Herein, graphite felt (GF)@V₂O₅ nanosheets is synthesized by hydrothermal and calcinating treatment, on the surface of which polyindole (PIn) nanospheres are anchored orderly using electrochem. deposition to obtain GF@V₂O₅@PIn ternary electrode material. The pseudocapacitive properties of both V₂O₅ nanosheets and PIn nanospheres are fully demonstrated through the synergistic effect of them, enabling ternary composite GVP-3 to exhibit superior electrochem. properties than two binary materials. The area capacitance of GVP-3 reaches 2254 mF/cm², which is significantly higher than that of GF@V₂O₅ with 1431 mF/cm² and GF@PIn with 647 mF/cm². The flexible quasi-solid-state asym. supercapacitor (FASC) can be operated at the potential window of 1.8 V with a significant energy d. of 1.423 mWh/cm³ (64.404Wh/kg) The excellent elec. capacitance and prominent energy d. of our device endow it with an overall improvement of elec. performance from 25% to 30%, which is compared to present researches.

And the article was included in Polymers (Basel, Switzerland) in 2021.Formula: C25H54ClN The following contents are mentioned in the article:

A large amount of industrial wastewater containing pollutants including toxic dyes needs to be processed prior to its discharge into the environment. Biol. materials such as sugarcane bagasse (SB) have been reported for their role as adsorbents to remove the dyes from water. In this study, the residue SB after fermentation was utilized for the dye removal. A combined pretreatment of NaOH and methyltrioctylammonium chloride was given to SB for lignin removal, and the pretreated SB was utilized for cellulase production from Bacillus aestuarii UE25. The strain produced 118 IU mL^-1 of endoglucanse and 70 IU mL^-1 of β-glucosidase. SEM and FTIR spectra showed lignin and cellulose removal in fermented SB. This residue was utilized for the adsorption of an azo dye, congo red (CR). The thermodn., isotherm and kinetics studies for the adsorption of CR revealed distinct adsorption features of SB. Untreated SB followed Langmuir isotherm, whereas pretreated SB and fermented SB obeyed the Freundlich isotherm model. The pseudo-second-order model fitted well for the studied adsorbents. The results of thermodn. studies revealed spontaneous adsorption with neg. standard free energy values. Untreated SB showed a 90.36% removal tendency at 303.15 K temperature, whereas the adsorbents comprised of pretreated and fermented SB removed about 98.35% and 97.70%, resp. The study provided a strategy to utilize SB for cellulase production and its use as an adsorbent for toxic dyes removal.

Efficient production of S-(+)-2-chlorophenylglycine by immobilized penicillin G acylase in a recirculating packed bed reactor was written by Xue, Ya-Ping;Jiang, Tao;Liu, Xue;Zheng, Yu-Guo. And the article was included in Biochemical Engineering Journal in 2013.Reference of 141109-14-0 The following contents are mentioned in the article:

(S)-(+)-2-Chlorophenylglycine 1 is an important intermediate in the synthesis of Clopidogrel. A recirculating packed bed reactor (RPBR) was constructed for efficient production of (S)-1 by kinetic resolution of racemic N-phenylacetyl-2- chlorophenylglycine 2 using immobilized penicillin G acylase (PGA). The immobilized PGA exhibited maximum activity at 50 °C and pH 8.0 with (R,S)-2 as substrate. The kinetic constants (K_m and v_max) of immobilized PGA were calculated to be 20.61 mM and 83.2 mM/min/g, resp. The substrate displayed inhibitory effect on immobilized PGA with inhibition constant of 221.23 mM. The immobilized PGA showed a strict enantiospecificity for substrate at different temperature, pH and substrate concentration examined The performance and productivity of RPBR were evaluated by several critical parameters, including immobilized PGA load, substrate feeding rate, height to diameter ratio and so on. The kinetic resolution process shows higher initial reaction rate and conversion by recycling 100 mL of substrate solution (80 mM) through RPBRs packed with 6.0 g immobilized PGA with a feeding rate of 1.5 mL/min while the H/D ratio was 4.0. The immobilized PGA-catalyzed kinetic resolution of (R,S)-2 was successfully operated in the RPBR for 60 batches, with an average productivity of 1.2 g/L/h for (S)-1 in high optical purity (>97% enantiomeric excess) in semi-continuous operation. The residual (R)-2 can be easily racemized and then used as substrate.

Experimental evidence for the direct involvement of Pd(0) and Pd(II) anionic phosphine complexes in the Mizoroki-Heck coupling reaction was written by Larina, Elizaveta V.;Kurokhtina, Anna A.;Vidyaeva, Elena V.;Lagoda, Nadezhda A.;Schmidt, Alexander F.. And the article was included in Molecular Catalysis in 2021.Safety of Tetramethylammonium chloride The following contents are mentioned in the article:

The role of ionic Pd species in the catalytic systems used for cross-coupling reactions has been revised in recent years, mainly utilizing in situ anal. techniques to detect catalyst species in the reaction mixture The possible inclusion of phosphine mols. in the active Pd complexes is still debated. We have carried out a comparative study on the differential selectivity of the Mizoroki-Heck reaction with competition between two aryl halides or two alkenes to elucidate the active Pd species in different types of catalytic systems, including those favoring the formation of ionic complexes. The sensitivity of the reaction differential selectivity of two competing aryl halides to the additives of tertiary phosphine and halide salts points to the catalytic activity of anionic Pd(0) complexes containing at least one phosphine ligand when the phosphine-containing catalytic systems are used. The changes of the reaction differential selectivity of two competing alkenes to phosphine and halide salt allow to propose the entrance of both phosphine and halide ions into the coordination sphere of active Pd(II) complexes possessing anionic character. In addition, evidence for the effect of phosphine ligand and salt additives on the composition of the active Pd complexes that determine the regioselectivity of the reaction is presented. The data obtained indicate the decisive role of anionic Pd species in the Mizoroki-Heck reaction using both phosphine-free and phosphine-containing catalytic systems. This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0Safety of Tetramethylammonium chloride).

Correlation of adsorbed and embedded palladium species in chitosan composite nanofibers with their catalytic activities for Suzuki reactions was written by Su, Baogang;Zhang, Qi;Shao, Linjun;Zhou, Shujing;Li, Jinjing;Du, Yijun;Qi, Chenze. And the article was included in Journal of Physics and Chemistry of Solids in 2022.SDS of cas: 13820-53-6 The following contents are mentioned in the article:

Heterogeneous palladium catalysts play an important role in the synthetic organic chem. Palladium species have been adsorbed on the surface of solid matrixes or embedded inside solid matrixes to prepare recyclable heterogeneous catalysts. Due to the different surrounding environment, these two type palladium species had different electronic properties and catalytic performances. In this study, we fabricated three series of chitosan composite nanofibers with adsorbed and embedded palladium species. Their fiber morphologies and chem. structures were characterized by SEM and FT-IR, resp. Positron annihilation lifetime spectra (PALS) showed that the intensities (I3) of o-Ps annihilations were all linearly decreased with the increase of palladium contents in the chitosan composite nanofibers. Moreover, compared with the palladium adsorbed chitosan composite nanofibers, the palladium embedded chitosan composite nanofibers had stronger o-Ps annihilation ability, which could be ascribed to the stronger electron donating property of embedded palladium species and higher crosslinking of chitosan mols. by embedded palladium species. At last, the I3 values were successfully correlated with the rate constants of chitosan supported palladium composite nanofibers catalyzed Suzuki reactions of iodobenzene with phenylboric acid. Therefore, we have developed a facile method to distinguish the adsorbed and embedded palladium species by PALS, which can be further related with their catalytic performance. This study involved multiple reactions and reactants, such as Sodium tetrachloropalladate(II) (cas: 13820-53-6SDS of cas: 13820-53-6).

Breaking the Corona Symmetry of Vesicles was written by Wei, Ping;Cornel, Erik Jan;Du, Jianzhong. And the article was included in Macromolecules (Washington, DC, United States) in 2021.HPLC of Formula: 5137-55-3 The following contents are mentioned in the article:

It is very challenging to completely break the corona symmetry of polymer vesicles as usually their inner and outer coronas have the same constituents. Herein, we propose a novel micelle-to-vesicle strategy to achieve this goal. First, a poly(ethylene oxide)₁₁₃-b-poly[N-iso-Pr acrylamide₄₅-stat-7-(2-methacryloyloxyethoxy)-4-methylcoumarin₁₀]-b-poly(2-(diethylamino)ethyl methacrylate)₂₈ [PEO₁₁₃-b-P(NIPAM₄₅-stat-CMA₁₀)-b-PDEA₂₈] triblock copolymer was synthesized and self-assembled into micelles, which were then transformed into asym. vesicles. The PEO block formed the outer corona of the vesicles, the PDEA block formed the inner corona of the vesicles (initially acted as the core-forming block of micelles), and the P(NIPAM-stat-CMA) block formed the membrane of vesicles (initially acted as the middle corona or the shell of micelles). Symmetry breaking was achieved during the micelle-to-vesicle transition where the locations of the inner and the outer coronas of vesicles were predetermined This asym. structure was confirmed by selective decoration with gold nanoparticles on the PDEA inner coronas. Furthermore, the inner coronas could efficiently prevent unwanted doxorubicin (DOX) leakage at physiol. conditions by turning themselves into an inner wall. Overall, we have hereby demonstrated a novel approach to prepare well-defined asym. vesicles through a finely controlled micelle-to-vesicle transition. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3HPLC of Formula: 5137-55-3).

To assess trueness of IM, MIL, and stereolithog. printed denture bases after manufacturing, hydrothermal cycling, and microwave sterilization. 16 Edentulous maxillary plaster models were poured using silicone mold and digitized by means of desktop scanner. For group IM, 16 denture bases were injection molded. MIL and SLA, denture bases were virtually designed and manufactured referring to digitized data. A total of 48 samples were scanned 1) after manufacturing, 2) after hydrothermal cycling three as well as 4) six cycles of microwave sterilization for 6 min each at 640 W. The 3D surface deviation of the total intaglio surface, the palate, the alveolar ridge, and the border seal region was evaluated on basis of RMSE and pos. and neg. mean deviations with inspection software. In comparison, IM showed increased, mainly pos., deviations at border seal. SLA presented highest total RMSE with increased neg. deviations, likewise at the border seal. In contrast to SLA, no differences between IM and MIL were measured after hydrothermal cycling. Following microwave sterilization, the trueness of SLA was higher compared to IM and MIL with no differences between MIL and IM. Distortion of IM and MIL was measured after the 3rd cycle with no further changes observed Subtractive manufacturing of denture bases results in the highest trueness, followed by IM and SLA. IM and SLA, hydrothermal cycling did not affect MIL. SLA printed denture bases remained dimensionally stable after microwave sterilization.

In this work, a series of dithiocarbamate derivatives bearing diverse quinazolinones I (R = bis(propan-2-yl)aminyl, pyrrolidin-1-yl, methyl(phenyl)aminyl, etc.; X = H, Cl), benzoxazinones II, and coumarin moieties III (R¹ = H, OH; R² = H, Cl; R³ = OH; R⁴ = H, Me, OH; R³R⁴ = -CH=CH-CH=CH-) was designed and synthesized via a one-pot three-component reaction. These compounds I, II, III produced good yields and functioned quickly under mild conditions, and the desired products were readily isolated. Their in vitro antitumor activities were evaluated by the Me thiazolyl tetrazolium (MTT) method against hepatoma carcinoma cells HCCLM-7, cervical carcinoma cells Hela, mammary adenocarcinoma cells MDA-MB-435S, colon carcinoma cells SW-480, laryngocarcinoma cells Hep-2, and mammary adenocarcinoma cells MCF-7. Three compounds were identified as the most promising candidates, due to their high potency and broad-spectrum antiproliferative activity (IC₅₀:3.5∼13.5μmol·L^-1). The activities of some lead compounds were more than 10-fold more potent than that of pos. control 5-fluorouracil (5-FU) (IC₅₀:8.1∼128.7μmol·L^-1).

Two-dimensional (2D) materials have spurred great interest in the field of catalysis due to their fascinating electronic and thermal transport properties. However, adding uniform mesopores to 2D metallic materials has remained a great challenge owing to the inherent high surface energy. Here, we introduce a generic liquid metal interfacial growth and exfoliation strategy to synthesize a library of penetrating mesoporous metallic nanosheets. The formation of liquid-metal/water interface promotes the adsorption of metal ion-encapsulated copolymer micelles, induces the self-limiting galvanic replacement reaction, and enables the exfoliation of products under mech. agitation. These 2D mesoporous metallic nanosheets with large lateral size, narrow thickness distribution, and uniform perforated structure provide facilitated channels and abundant active sites for catalysis. Typically, the generated mesoporous PtRh nanosheets (mPtRh NSs) exhibit superior electroactivity and durability in hydrogen evolution reaction as well as methanol electrooxidation in alk. media. Moreover, the constructed sym. mPtRh NSs cell requires only a relative low electrolysis voltage to achieve methanol-assisted hydrogen production compared with traditional overall water electrolysis. The work reveals a specific growth pattern of noble metals at the liquid-metal/water interface and thus introduces a versatile strategy to form 2D penetrating mesoporous metallic nanomaterials with extensive high-performance applications.

As an alternative to the conventional industrial Haber-Bosch process, photoelectrochem. (PEC) routes that are powered by renewable solar energy hold great promise for N₂ reduction reaction (NRR) towards NH₃ synthesis at ambient conditions. However, great challenges remain in promoting NH₃ production rate for the PEC NRR devices, especially with the earth-abundant catalysts. Here we report an integrated LixMoO₃/n+np+-Si photocathode could achieve an unprecedented PEC NH₃ yield rate of 8.7 μg cm^-2h^-1, which is among the highest PEC NRR systems ever reported. With an optically and electrocatalytically decoupled configuration, the integrated PEC photocathode could harvest the sunlight sufficiently and simultaneously promote the catalytic kinetics, thus leading to the improved NH3 synthesis. More importantly, such high PEC NRR performance is derived from earth-abundant elements without precious noble metals. Verified by the electrochem. experiments and d. functional theory (DFT) calculations, the lithiation strategy gives rise to dramatic structural distortion accompanying the abundant oxygen vacancies and Mo⁵⁺ ions, which results in faster NRR kinetics and activates inert MoO₃ into efficient LixMoO₃ electrocatalyst towards NH₃ synthesis. This work holds great promise in constructing monolithic PEC device to directly harvest solar light for artificial ammonia photosynthesis. This study involved multiple reactions and reactants, such as Lithium chloride (cas: 7447-41-8Recommanded Product: Lithium chloride).
