Electric Literature of C4H12KNaO10In 2019 ,《Study on structure and phase transition of an eco-friendly ferroelectric composite prepared from cellulose nanoparticles mixed with Rochelle salt》 was published in Phase Transitions. The article was written by Nguyen, Hoai Thuong; Mai, Bich Dung. The article contains the following contents:

An eco-friendly ferroelec. nanocomposite from cellulose nanoparticles (CNP) and Rochelle salt (RS) at different composition mass ratios was synthesized for clarifying phase transition anomalies after carefully characterizing by scanning electron microscope (SEM), X-ray diffraction (XRD) and Fourier-transform IR spectroscopy (FTIR) techniques. The dielec. experiments were conducted in a temperature range from 5°C to 60°C under a weak elec. field (2 V/cm) at 1 kHz. The obtained results indicated the presence of the upper Curie point characteristic for volume part of RS in the composite and an addnl. higher-temperature phase transition which was shifted toward higher temperature with increasing CNP content. Besides, at relatively high CNP content, the ferroelec. phase of RS maintained up to its decomposition temperature The intermol. hydrogen bonds formed between cellulose and Rochelle salt is assumed to be responsible for the obtained anomalies.

Recommanded Product: Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrateIn 2020 ,《High Protein-Loading Silica Template for Heterogeneous Protein Crystallization》 appeared in Crystal Growth & Design. The author of the article were Chen, Wenqian; Park, Sung Joon; Kong, Fanlu; Li, Xiaoyu; Yang, Huaiyu; Heng, Jerry Y. Y.. The article conveys some information:

As a purification technol., crystallization is advantageous over chromatog. and precipitation in terms of purity, cost and scalability. In general, proteins have slow crystallization kinetics due to their complex configurations, but this problem can be overcome with heterogeneous nucleants. High protein-loading mesoporous silica is a promising nucleant due to its favorable interaction with protein. The current study employs such a template in the batch crystallization of lysozyme and thaumatin at 1 mL scale. Using lysozyme as the main model protein, the results show that the template had high protein loading (220 – 300 mg lysozyme/g silica) and induced significantly faster crystallization as compared to the unseeded samples over a wide range of initial protein concentration (10.0 – 47.5 mg/mL in the case of lysozyme) at 25° with 0.5 M potassium sodium tartrate tetrahydrate (precipitant) concentration It was found that the template had to be saturated with the target protein before the experiments to achieve faster kinetics or else it could delay the crystallization process. These findings were re-affirmed by the crystallization experiments of thaumatin. The current study demonstrates the effectiveness of high protein-loading silica as nucleant in protein crystallization and the importance of its pre-treatment with the target protein. In the experiment, the researchers used many compounds, for example, Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate(cas: 6381-59-5Recommanded Product: Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate)

In 2019,Journal of Membrane Science included an article by Wang, Rui; Shi, Xiansong; Zhang, Zhe; Xiao, Ankang; Sun, Shi-Peng; Cui, Zhaoliang; Wang, Yong. COA of Formula: C9H6O6. The article was titled 《Unidirectional diffusion synthesis of covalent organic frameworks (COFs) on polymeric substrates for dye separation》. The information in the text is summarized as follows:

Covalent organic frameworks (COFs) are regarded as important candidates for the preparation of advanced membranes with remarkable performances on account of their uniform and tailorable channels and good chem. stability. The development of COFs-based membranes is burgeoning, and there remains lacking of facile and mild methods to prepare to these membranes. Herein, we report on the unidirectional diffusion synthesis (UDS) of TpPa (an imine-based COFs) on com. polyvinylidene fluoride (PVDF) microfiltration substrates for the preparation of composite COFs-based membranes at room temperature The p-phenylenediamine (Pa) aqueous solution and 1,3,5-triformylphloroglucinol (Tp) n-hexane solution were sep. charged into the two sides of a diffusion cell. With the suitable solution pairs and molar ratio of two precursors, only Pa mols. can pass through the macropores of PVDF to react with Tp mols. at the phase interface formed by this solution pairs, leading to the in situ synthesis of TpPa layer on the top side of PVDF substrates. The membrane fabricated with a synthesized duration of 24 h exhibits a superior selectivity for dyes (>90%) and appreciable water permeance (60 L·m-2·h-1·bar-1). The permeance of the resultant membrane is ∼2-20 times higher than other reported membranes with comparable dye rejections. The UDS offers a facile and mild process to directly grow COFs on porous polymeric substrates to construct composite membranes capable of efficient separations of dye mols. In the experiment, the researchers used 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde(cas: 34374-88-4COA of Formula: C9H6O6)

Hydrazine is a promising energy carrier for fuel cells owing to its combined advantages of high theor. cell voltage, high-power d., and no greenhouse gas emission. By using an electroless plating process, we have prepared a robust Ni-B film grown on Ni foam that is highly effective for hydrazine electrooxidation in alk. media. The effects of reaction temperature, concentrations of hydrous hydrazine and sodium hydroxide in the fuel solution on performance of hydrazine electrooxidation reaction are investigated. The mechanistic reason for the property advantage of as-prepared Ni-B/Ni foam catalyst over the relevant catalysts is discussed based on careful kinetics studies and characterization. The facile synthesis of Ni-based catalyst with high activity and good stability is of clear significance for the development of hydrous hydrazine as a viable energy carrier.

In 2017,Park, Sang Jin; Ko, Tae-Jun; Yoon, Juil; Moon, Myoung-Woon; Oh, Kyu Hwan; Han, Jun Hyun published 《Copper circuit patterning on polymer using selective surface modification and electroless plating》.Applied Surface Science published the findings.Electric Literature of C4H12KNaO10 The information in the text is summarized as follows:

We have examined a potential new and simple method for patterning a copper circuit on PET substrate by copper electroless plating, without the pretreatment steps (i.e., sensitization and activation) for electroless plating as well as the etching processes of conventional circuit patterning. A patterned mask coated with a catalyst material, Ag, for the reduction of Cu ions, is placed on a PET substrate. Subsequent oxygen plasma treatment of the PET substrate covered with the mask promotes the selective generation of anisotropic pillar- or hair-like nanostructures coated with co-deposited nanoparticles of the catalyst material on PET. After oxygen plasma treatment, a Cu circuit is well formed just by dipping the plasma-treated PET into a Cu electroless plating solution By increasing the oxygen gas pressure in the chamber, the height of the nanostructures increases and the Ag catalyst particles are coated on not only the top but also the side surfaces of the nanostructures. Strong mech. interlocking between the Cu circuit and PET substrate is produced by the large surface area of the nanostructures, and enhances peel strength. Results indicate this new simple two step (plasma surface modification and pretreatment-free electroless plating) method can be used to produce a flexible Cu circuit with good adhesion.

Taylor, Nicole M; Enns, Leah N published an article in Child neuropsychology. The title of the article was 《Factors predictive of a fetal alcohol spectrum disorder diagnosis: Parent and teacher ratings.》.Application of 591-70-8 The author mentioned the following in the article:

Diagnostic assessment in Fetal Alcohol Spectrum Disorder (FASD) is informed by multidisciplinary assessment incorporating objective (i.e., test measures) and subjective means, such as parent and teacher behavior ratings. The purpose of this study was to extend our previous neuropsychological test findings by identifying parent and teacher ratings of academic achievement, attention, executive functioning, and adaptive functioning as predictors of an FASD diagnosis. The charts of 315 children and adolescents with prenatal alcohol exposure (PAE) who underwent assessment for FASD were retrospectively reviewed. Direct logistic regressions analyzed the contribution of different ratings on the likelihood of an FASD diagnosis. The results suggest that a number of rating measures do contribute toward accurately differentiating those with FASD from within a PAE population, including teacher ratings of learning problems, inattention, and adaptive skills. The classification accuracy for each regression was clinically significant (59.1-70.8%). Children with worse ratings on these variables are approximately 1.5 to 2 times more likely to receive an FASD diagnosis. Only teacher ratings (not parent) significantly contributed to whether a diagnosis was made, suggesting that teacher observational rating scales are a critical component of an FASD assessment. Together with our previous research examining neuropsychological evaluation and FASD diagnostic assessment, this study helps to further guide decisions to streamline care in multidisciplinary assessment and intervention planning.

Recommanded Product: 34374-88-4This research focused onzinc air battery iron nitrogen doped mesoporous carbon; covalent organic framework oxygen reduction electrocatalyst. The article conveys some information:

The rational design and synthesis of mesoporous functional materials is of great significance to tackle fundamental challenges in materials science and to yield practical solutions for efficient energy utilization. Here, a novel p-toluenesulfonic acid-assisted mechanochem. approach is used to prepare a silica-templated bipyridine-containing covalent organic framework (COF), which can be further converted into an iron-nitrogen-doped mesoporous carbon (mC-TpBpy-Fe) upon carbonization and template removal. The resulting mC-TpBpy-Fe exhibits a large pore volume and surface area, which significantly promote the mass transfer efficiency and increase the accessibility of the active sites, yielding a high ORR activity with a competitive half-wave potential of 0.845 V and limiting c.d. of 5.92 mA/cm2 (vs 0.852 V and 5.57 mA/cm2 for Pt/C). Application of this COF derived mesoporous carbon within a Zn-air battery revealed that it can operate in ambient conditions with a competitive discharge performance, showing its potential for practical applications.

In 2022,Yadav, Sushma; Chauhan, Maruf; Jacob, MercyKutty; Malhotra, Priti published an article in New Journal of Chemistry. The title of the article was 《Distinguished performance of biogenically synthesized reduced-graphene-oxide-based mesoporous Au-Cu2O/RGO ternary nanocomposites for sonocatalytic reduction of nitrophenols in water》.Application In Synthesis of Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate The author mentioned the following in the article:

In order to achieve a sustainable environment, the development of eco-friendly protocols for the production of noble metal catalysts has been the primary focus of major research. Ternary nanocomposites (TNCs) comprising Au-Cu2O anchored on reduced graphene oxide (Au-Cu2O/RGO) were synthesized employing a novel one-pot greener approach using sugarcane bagasse (SB) waste and Fehling’s solution without engaging harmful chems. as reagents and surfactants. In addition to the mild reducing capability of the polysaccharides present in SB, it also induces functionalization of RGO, avoiding aggregation of the reduced sheets and thereby providing in situ stabilization of Cu2O. The sonocatalytic performance of biogenically synthesized Au-Cu2O/RGO TNCs for reducing nitrophenols to the corresponding aminophenol in the presence of sodium borohydride (NaBH4) as a reducing agent was estimated TNCs showed high performance in the sonocatalytic reduction of 4-nitrophenols (4-NP), 2-nitrophenol (2-NP), and 3-nitrophenol (3-NP) with 88%, 72%, and 78% conversion within 90, 60, and 40 s, resp. The sonocatalytic activity of Au-Cu2O/RGO was enhanced compared to that of Cu2O and Cu2O/RGO due to the easier electron transfer process. The current work showcases a novel, eco-friendly, and benign protocol for the synthesis of nanocomposites (NCs) and simultaneously emphasizes the exploration of decorated metal oxide as a nanocatalyst with high catalytic potential; compared to unanchored metal oxide nanoparticles (NPs), the supported NCs exhibit greater efficacy and ease of recovery.
