On March 31, 2022, Quattrosoldi, Silvia; Guidotti, Giulia; Soccio, Michelina; Siracusa, Valentina; Lotti, Nadia published an article.Recommanded Product: Pentane-1,5-diol The title of the article was Bio-based and one-day compostable poly(diethylene 2,5-furanoate) for sustainable flexible food packaging: Effect of ether-oxygen atom insertion on the final properties. And the article contained the following:

In the present work, the effect of ether oxygen atom introduction in a furan ring-containing polymer has been evaluated. Solvent-free polycondensation process permitted the preparation of high mol. weight poly(diethylene 2,5-furandicarboxylate) (PDEF), by reacting the di-Me ester of 2,5-furandicarboxylic acid with diethylene glycol. After mol. and thermal characterization, PDEF mech. response and gas barrier properties to O2 and CO2, measured at different temperatures and humidity, were studied and compared with those of poly(butylene 2,5-furandicarboxylate) (PBF) and poly(pentamethylene 2,5-furanoate) (PPeF) previously determined Both PDEF and PPeF films were amorphous, differently from PBF one. As concerns mech. response, PDEF is more flexible than PBF but stiffer than PPeF. Moreover, PDEF is the most thermally stable (temperature of maximum degradation rate being 418 for PDEF, 407 for PBF and 414°C for PPeF) and hydrophilic (water contact angle being 74° for PDEF, 90° for PBF and 93° for PPeF), with gas barrier performances very similar to those of PPeF (O2 and CO2 transmission rate being 0.0022 and 0.0018 for PDEF and, 0.0016 and 0.0014 cm3 cm/m2 d atm for PPeF). Lab scale composting experiments indicated that PDEF and PPeF were compostable, the former degrading faster, in just one day. The results obtained are explained on the basis of the high electronegativity of ether oxygen atom with respect to the carbon one, and the consequent increase of dipoles along the macromol. The experimental process involved the reaction of Pentane-1,5-diol(cas: 111-29-5).Recommanded Product: Pentane-1,5-diol

Weng, Can; Chen, Jiachen; Yang, Jin; Zhou, Mingyong; Jiang, Bingyan published an article in 2021, the title of the article was Experimental Investigation and Molecular Dynamics Simulation on the Anti-Adhesion Behavior of Alkanethiols on Nickel Insert in Micro Injection Molding.Formula: C10H22S And the article contains the following content:

Due to the adhesion between the polymer melt and nickel (Ni) mold insert in the micro injection molding process, deformation defects frequently occur when the microstructures are demolded from the insert. In this study, self-assembled alkanethiols were applied to modify the surface of Ni mold insert to reduce its surface energy. Exptl. trials were undertaken to explore the effect of alkanethiols coating on the replication quality. After that, mol. dynamics (MD) simulation was then used to investigate the adhesion behavior between the self-assembled coating and polypropylene (PP) by establishing three different types of alkanethiol material. The interaction energy, the potential energy change and radial distribution function were calculated to study the anti-adhesion mechanism. Exptl. results show that all the three coatings can effectively decrease the adhesion and therefore promote the replication fidelity. It is demonstrated in MD simulation that the adhesion mainly comes from the van der Waals (vdW) force at the interface. The arrangement of sulfur atom on the Ni surface results in different absorbing behaviors. Compared with that of the PP-Ni interface, the interfacial energy and adhesion work after surface treatment is significantly reduced. The experimental process involved the reaction of 1-Decanethiol(cas: 143-10-2).Formula: C10H22S

On April 30, 2020, De Jaco, Robert F.; Dorneles de Mello, Matheus; Nguyen, Huong Giang T.; Jeon, Mi Young; van Zee, Roger D.; Tsapatsis, Michael; Siepmann, Joern Ilja published an article.Synthetic Route of 111-29-5 The title of the article was Vapor- and liquid-phase adsorption of alcohol and water in silicalite-1 synthesized in fluoride media. And the article contained the following:

In this work, batch-adsorption experiments and mol. simulations are employed to probe the adsorption of binary mixtures containing ethanol or a linear alkane-1,n-diol solvated in water or ethanol onto silicalite-1. Since the batch-adsorption experiments require an addnl. relationship to determine the amount of solute (and solvent) adsorbed, as only the bulk liquid reservoir can be probed directly, mol. simulations are used to provide a relationship between solute and solvent adsorption for input to the exptl. bulk measurements. The combination of bulk exptl. measurements and simulated solute-solvent relationship yields solvent and solute loadings that are self-consistent with simulation alone, and allow for an assessment of the various assumptions made in the literature. At low solution concentrations, the solute loading calculated is independent of the assumption made. At high concentrations, a negligent choice of assumption can lead to systematic overestimation or underestimation of calculated solute loading. The experimental process involved the reaction of Pentane-1,5-diol(cas: 111-29-5).Synthetic Route of 111-29-5

On December 5, 2020, Shumbula, Ndivhuwo P.; Ndala, Zakhele B.; Nkabinde, Siyabonga S.; Kolokoto, Tshwarela; Shumbula, Poslet M.; Mdluli, Phumlani S.; Hlatshwayo, Thulani; Mlambo, Mbuso; Moloto, Nosipho published an article.Name: 1-Decanethiol The title of the article was Experimental and theoretical studies of 1-alkanethiols SAMs of various chain-lengths on gold nanoparticles and their effect on SERS, stability and surface properties. And the article contained the following:

1-Alkanethiol SAMs on AuNPs have shown great potential towards the development of new functional materials. This is mainly due to the formation of dense, tightly bonded and well-ordered systems on the surface of AuNPs. This work showcases how the chain-length of 1-alkanethiols affects the stability and surface properties of AuNPs and the SERS effect. Using exptl. and theor. studies (by means of DFT), this work shows the interaction between 1-alkanethiols of 3 different chain-lengths and AuNPs. The effects on the optical properties, surface charge, stability and SERS were also investigated. The red shift of surface plasmon resonance band was observed as a result of the interaction between AuNPs and 1-alkanethioals. The Zeta potential indicated a strong electrostatic repulsion between AuNPs which was reduced after functionalizing with 1-alkanethiols. The long chain alkanethiol was found to strongly reduce the surface charge due to strong interaction with AuNPs. The calculated nucleophilic center cross-sections for all alkanethiols were found to increase with the chain-length, indicating a strong interaction existed between long chain alkanethiol and AuNPs. The SERS data shows an increase in Raman intensities of all 1-alkanethiols adsorbed on the surface of AuNPs. Both the exptl. and theor. data shows that the alkanethiol with short chain-length possesses the strongest Raman signal enhancement. The experimental process involved the reaction of 1-Decanethiol(cas: 143-10-2).Name: 1-Decanethiol

On December 31, 2022, van der Sman, R. G. M.; Jurgens, A.; Smith, A.; Renzetti, S. published an article.Quality Control of SweetPearlR P300 DC Maltitol The title of the article was Universal strategy for sugar replacement in foods. And the article contained the following:

In this paper we present a sugar replacements strategy, derived from phys. theory, which we think is applicable for a wide range of food categories. The strategy is based on the hypothesis that reformulated foods must mimic the values of two phys. characteristic numbers, related to the plasticizing and hygroscopic properties of sugar, to reproduce the texture of a sugar-rich product. We will show the validity of the strategy for reformulated biscuits, using exptl. determination of phys. properties of dough and baked biscuits, as well as sensorial evaluation by a trained panel. Our investigations shown that the majority of these phys. and sensorial attributes correlate with the two phys. characteristic numbers Furthermore, multiple reformulations can be defined which are close to the reference product (in terms of the two phys. characteristic numbers), which are indeed scored similar by the trained sensory panel. Hence, our strategy also leaves room for further optimization of the reformulated food towards dietary fiber content, laxative properties or sweetness.

On April 12, 2022, Singh, Himanshu; Sharma, Sumit published an article.Recommanded Product: 1-Decanethiol The title of the article was Determination of Equilibrium Adsorbed Morphologies of Surfactants at Metal-Water Interfaces Using a Modified Umbrella Sampling-Based Methodology. And the article contained the following:

Surfactants adsorb to metal-water interfaces in various morphologies, including self-assembled monolayers (SAMs), cylindrical and spherical micelles or hemimicelles. Current mol. simulation methods are unable to efficiently sample the formation of these morphologies because of the large diffusive/energetic barriers. We introduce a modified umbrella sampling-based methodol. that allows sampling of these morphologies from any initial configuration and provides free energy differences between them. Using this methodol., we have studied adsorption behavior of cationic [quaternary ammonium (quat) of 4 and 12 carbon long alkyl tails], uncharged [decanethiol], and anionic [phosphate monoester] surfactants and their mixtures at a gold-water interface. We find that while Coulombic repulsion between the charged head groups of quat-4 limits their adsorption to a sparse layer, stronger hydrophobic interactions between the alkyl tails of quat-12 promote adsorption resulting in a morphol. with adsorbed hemispherical micelles sitting atop a monolayer. Decanethiol mols. adsorb in a densely packed bilayer with the mols. standing-up on the surface in the first layer and lying parallel to the surface in the second layer. Cationic and anionic surfactant mixtures display a synergistic adsorption behavior. These results elucidate the role of mol. characteristics in dictating the nature of adsorbed morphologies of surfactants at metal-water interfaces.

On April 7, 2020, Tie, Lu; Zhao, Siyang; Guo, Zhiguang; Li, Jing published an article.Recommanded Product: 1-Decanethiol The title of the article was Fine Switching between Underwater Superoleophilicity and Underwater Superoleophobicity while Maintaining Superhydrophobicity. And the article contained the following:

Switching between superhydrophobicity/underwater superoleophilicity and superhydrophilicity/underwater superoleophobicity has been widely designed. Recently, superwettability is subdivided into multiple extreme wetting states for oil, water, and air as wetting and medium phases. However, fine switching among the multiple superwettability is rare. Here, a pH-responsive case is presented to demonstrate the fine switching between underwater superoleophilicity and underwater superoleophobicity while maintaining superhydrophobicity. The surface chem. of silver-roughened copper coatings is elaborately manipulated by water-repellent perfluoroalkyl and alkyl chains and the smart terminal carboxyl group. By adjusting the pH value of water, the completely opposite extreme wetting states for oil in water are precisely controlled. Simultaneously, the extreme repellence for water in the air can be kept owing to the fairly low surface energy of the perfluoroalkyl chain. This discovery accelerates the subdivision of superwettability and the achievement of unusual superwetting switching. The experimental process involved the reaction of 1-Decanethiol(cas: 143-10-2).Recommanded Product: 1-Decanethiol
