In 2019,Nature Communications included an article by Yang, Hao; Yang, Leixin; Wang, Hongjian; Xu, Ziang; Zhao, Yumeng; Luo, Yi; Nasir, Nayab; Song, Yimeng; Wu, Hong; Pan, Fusheng; Jiang, Zhongyi. Recommanded Product: 34374-88-4. The article was titled 《Covalent organic framework membranes through a mixed-dimensional assembly for molecular separations》. The information in the text is summarized as follows:

Covalent organic frameworks (COFs) hold great promise in mol. separations owing to their robust, ordered and tunable porous network structures. Currently, the pore size of COFs is usually much larger than most small mols. Meanwhile, the weak interlamellar interaction between COF nanosheets impedes the preparation of defect-free membranes. Herein, we report a series of COF membranes through a mixed-dimensional assembly of 2D COF nanosheets and 1D cellulose nanofibers (CNFs). The pore size of 0.45-1.0 nm is acquired from the sheltering effect of CNFs, rendering membranes precise mol. sieving ability, besides the multiple interactions between COFs and CNFs elevate membrane stability. Accordingly, the membranes exhibit a flux of 8.53 kg m-2 h-1 with a separation factor of 3876 for n-butanol dehydration, and high permeance of 42.8 L m-2 h-1 bar-1 with a rejection of 96.8% for Na2SO4 removal. Our mixed-dimensional design may inspire the fabrication and application of COF membranes.

In 2019,Dalton Transactions included an article by Yue, Jie-Yu; Wang, Ling; Ma, Yu; Yang, Peng; Zhang, Ying-Qiu; Jiang, Yu; Tang, Bo. Application of 34374-88-4. The article was titled 《Metal ion-assisted carboxyl-containing covalent organic frameworks for the efficient removal of Congo red》. The information in the text is summarized as follows:

Covalent organic frameworks (COFs) have been utilized as mol. sieves to adsorb or remove or sep. a wide range of substances. Herein, a new carboxyl-containing COF (COF-COOH) is fabricated from the polymerization of 1,3,5-triformylphloroglucinol (TP) and 4,4′-diamino-[1,1′-biphenyl]-3,3′-dicarboxylic acid (DBA). COF-COOH displays good adsorption performance on Congo red (CR) through hydrogen bonds and π-π stacking interactions. Through post-modification with Ca2+/Ni2+ ions, the adsorption capacity of COF-COOCa/COF-COONi to CR is improved, which is due to the coordinated metal cations having a pos. contribution to the electrostatic interactions. At 25°C, the maximum adsorption amount of COF-COOCa and COF-COONi to CR is 704.23 mg g-1 and 781.25 mg g-1, resp. The removal efficiency of COF-COOCa to CR is 95% and that of COF-COONi is 96%. This demonstrates that the new metal ion-assisted COFs are viable adsorbents to remove dye pollutants, which are harmful to the environment and to human health, from wastewater.

A method for the Cu-catalyzed borylmethylation and borylation of vinyl cyclic carbonates through an SN2′ mechanism is reported. These singular reactions involve selective SN2′ allylic substitutions with concomitant ring opening of the cyclic carbonate and with extrusion of CO2 and formation of a useful hydroxyl functionality in a single step. The stereoselectivity of the homoallylic borylation and allylic borylation processes can be controlled, and synthetically useful unsaturated (E)-pent-2-ene-1,5-diols and (E)-but-2-ene-1,4-diols are accessed.

In 2016,Muench, Falk; Felix, Eva-Maria; Rauber, Markus; Schaefer, Sandra; Antoni, Markus; Kunz, Ulrike; Kleebe, Hans-Joachim; Trautmann, Christina; Ensinger, Wolfgang published 《Electrodeposition and electroless plating of hierarchical metal superstructures composed of 1D nano- and microscale building blocks》.Electrochimica Acta published the findings.Computed Properties of C4H12KNaO10 The information in the text is summarized as follows:

The fabrication of ordered superstructures composed of nano- and microscale building blocks is of tremendous interest. The authors present a versatile approach for the synthesis of hierarchical and free-standing metal architectures of high structural complexity. Using the ion-track etching technique, hierarchically porous polycarbonate membranes were obtained, which are employed as nanocasting templates. Pore filling is accomplished by the two complementary wet-chem. techniques electrodeposition and electroless plating. Depending on the pore filling mechanism and the template structure, a wide range of novel metal nano-/micro-architectures can be realized. The products can be characterized as hierarchical assemblies of 1-dimensional structures (nanotubes, nanowires, microwires, nanorods). With electrodeposition, complete pore filling is achieved, which gave wire-based morphologies. Special attention is dedicated to the controlled partial filling of the pores with electroless plating, which allows the simultaneous deposition of tubes and – depending on the conformity of the plating reaction and the deposition time – narrower arrays of tubes, wires or rods. To demonstrate the favorable functional properties of the obtainable products, a Ag-based wire-tube assembly is employed in the enzyme-free and selective electrochem. detection of H2O2. An excellent sensitivity of 1340 μA mM-1 cm-2 and a fast response time of <2 s is achieved, which is explained by the absence of binders, the well-accessible, open-pored structure, the presence of continuous conduction pathways and the high surface area of the material.

《Boundary lubrication: adsorption of oil additives on steel and ceramic surfaces and its influence on friction and wear》 was written by Studt, P.. Synthetic Route of C18H38O And the article was included in Tribology International on April 30 ,1989. The article conveys some information:

The influence on the friction of adsorbed films of polar organic compounds on surfaces sliding or rolling over each other is dependent on the structure of the adsorbed species. Straight-chain compounds with polar end groups, long chain compounds with the polar group in the middle of the chain and polar cyclic organic compounds behave quite differently. The efficiency of extreme pressure additives, is dependent partly on their concentration on the mating surfaces. An increase of adsorbability of these additives, which concentrates them at the metal-oil interface, increases their efficiency. The boundary lubrication of ceramics by adsorbed films is strongly influenced by the nature of the ceramic (ion lattice or covalently bonded crystal). The experimental part of the paper was very detailed, including the reaction process of Octadecan-9-ol(cas: 591-70-8Synthetic Route of C18H38O)

Octadecan-9-ol(cas: 591-70-8) belongs to hydroxy-containing compounds. Hydroxy groups participate in the dehydration reactions that link simple biological molecules into long chains.

In 2018,Kim, Geon Hwee; Shin, Jung Hwal; An, Taechang; Lim, Geunbae published 《Junction-free Flat Copper Nanofiber Network-based Transparent Heater with High Transparency, High Conductivity, and High Temperature》.Scientific Reports published the findings.Electric Literature of C4H12KNaO10 The information in the text is summarized as follows:

Transparent conducting electrodes (TCE) are widely used in a variety of applications including displays, light-emitting diodes (LEDS), and solar cells. An important factor in TCE design is active control of the sheet resistance and transparency; as these are inversely proportional, it is essential to develop a technol. that can maintain high transparency, while actively controlling sheet resistance, for a range of applications. Here, a nanofiber network was fabricated based on direct electrospinning onto a three-dimensional (3-D) complex substrate; flat metal electrodes without junction resistance were produced using heat treatment and electroless deposition. The fabricated transparent electrode exhibited a transparency of over 90% over the entire visible light range and a sheet resistance of 4.9 O/sq. Adhesion between the electrode and substrate was superior to other electrospinning-based transparent electrodes. The performance of the transparent electrode was verified by measurements taken while using the electrode as a heater; a maximum temperature of 210°C was achieved. The proposed copper nanofiber-based heater electrode offers the advantages of transparency as well as application to complex 3-D surfaces. In the experiment, the researchers used many compounds, for example, Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate(cas: 6381-59-5Electric Literature of C4H12KNaO10)
