(Dicyclopentadiene) platinum(II) dichloride: An efficient catalyst for the hydrosilylation reaction between alkenes and triethoxysilane was written by Wu, Huarui;Zheng, Chaoyue;Chen, Naiwu;Zhu, Jie;Gao, Deqing. And the article was included in Tetrahedron Letters in 2017.Recommanded Product: 12083-92-0 This article mentions the following:

(Dicyclopentadiene) Pt(II) dichloride is an efficient hydrosilylation catalyst (homogeneous) upon a wide variety of functionalized alkenes and alkenes terminated with chem. moieties (di-Ph amino-, N-carbazol- and N-isoindoline-1,3-dione-). It is noteworthy that the hydrosilylation of aminated alkenes with triethoxysilane exhibited a yield of over 70% and a selectivity (γ-isomer/β-isomer) of >3/1. Due to steric hindrance (lowering Markovnikov probability), the alkenes with big terminal moieties (di-Ph amino-, N-carbazol- and N-isoindoline-1,3-dione-) presented the highest ratio of anti-Markovnikov isomers. A strategy for the hydrosilylation of a protected diamino chelating alkene was developed. In the experiment, the researchers used many compounds, for example, Dichlorodi(cyclopenta-1,3-dien-1-yl)platinate(II) (cas: 12083-92-0Recommanded Product: 12083-92-0).

Dichlorodi(cyclopenta-1,3-dien-1-yl)platinate(II) (cas: 12083-92-0) belongs to organic chlorides.

A proposal for a new in vitro method for direct classification of eye irritants by cytotoxicity test – Preliminary study was written by Krakowian, Daniel;Gadarowska, Dominika;Daniel-Wojcik, Anna;Mrzyk, Inga. And the article was included in Toxicology Letters in 2021.Computed Properties of C13H9Cl3N2O This article mentions the following:

None of the in vitro method are suitable for directly classifying of a substance as an eye irritant (category 2). They can classify substance as category 1 (serious eye damage) or as “no category” (not requiring classification). The aim of this study was to develop a new method for direct classification of a substance as category 2. Cytotoxicity Assay to Assess Eye Irritation (CEI) was performed on fibroblast – HDFn cell line with 36 substances. 5 concentrations of all substances and neat substances were applied directly to the cells. After 30 min, medium was added and cells were incubated at 37°C. The next day, the cytotoxicity assay was performed (MTT assay in the first run and NRU assay in the second run). Based on viability and IC50 value (concentration with 50% viability) a substance could be classified in category 2, category 1, and as “no category”. The results obtained were referred to ECHA database. This new method had high sensitivity (53.8-88.9%), specificity (73.9-100.0%) and accuracy (69.4-88.9%) in the classification to all categories. It effectively classifies not only substances in category 2 but also in category 1 and substances that do not require classification. In the experiment, the researchers used many compounds, for example, 1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea (cas: 101-20-2Computed Properties of C13H9Cl3N2O).

1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea (cas: 101-20-2) belongs to organic chlorides. An organic chloride is an organic compound containing at least one covalently bonded atom of chlorine.

Shape-controlled SnO and their improved properties in the field of gas sensor, photocatalysis, and lithium-ion battery was written by Ren, Qianqian;Zhang, Xinping;Guo, Yuxi;Xu, Manzhang;Zhu, Hongyang;Yun, Jiangni;Zhao, Wu;Zhang, Zhiyong;Wang, Yingnan. And the article was included in Sensors and Actuators, B: Chemical in 2022.Safety of 3,7-Bis(dimethylamino)phenothiazin-5-ium chloride This article mentions the following:

In this paper, over 20 kinds of tin monoxide (SnO) morphologies are prepared by using a facile solvothermal process. Among all these obtained SnO materials, the shapes with unique morphologies such as bowl-, pompon-, sheet-, hollow frame-like structures exhibit excellent NO₂ gas sensing, photocatalytic degradation, and lithium-ion batteries properties due to their large sp. surface area and more active sites compared with other shapes. For the NO₂ gas sensors properties, these SnO with unique morphologies exhibit excellent sensing performance, including low detection limits (≤ 100 ppb, even reaching 5 ppb), short response and recovery time (< 100 s). Finally, the as-prepared SnO are used as the efficient photocatalysts and lithium-ion battery anode material. These performances have been improved significantly compared with other shaped SnO proposed by other reports. All these advantages indicate the huge application potential of SnO in the field of photocatalysis, gas sensitivity, and lithium-ion battery performance. In the experiment, the researchers used many compounds, for example, 3,7-Bis(dimethylamino)phenothiazin-5-ium chloride (cas: 61-73-4Safety of 3,7-Bis(dimethylamino)phenothiazin-5-ium chloride).

3,7-Bis(dimethylamino)phenothiazin-5-ium chloride (cas: 61-73-4) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. Alkyl chlorides are versatile building blocks in organic chemistry. While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available.Safety of 3,7-Bis(dimethylamino)phenothiazin-5-ium chloride

Oxysterols Profile in Zebrafish Embryos Exposed to Triclocarban and Propylparaben-A Preliminary Study was written by Merola, Carmine;Vremere, Anton;Fanti, Federico;Iannetta, Annamaria;Caioni, Giulia;Sergi, Manuel;Compagnone, Dario;Lorenzetti, Stefano;Perugini, Monia;Amorena, Michele. And the article was included in International Journal of Environmental Research and Public Health in 2022.Recommanded Product: 1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea This article mentions the following:

Oxysterols have long been considered as simple byproducts of cholesterol metabolism, but they are now fully designed as bioactive lipids that exert their multiple effects through their binding to several receptors, representing endogenous mediators potentially involved in several metabolic diseases. There is also a growing concern that metabolic disorders may be linked with exposure to endocrine-disrupting chems. (EDCs). To date, there are no studies aimed to link EDCs exposure to oxysterols perturbation-neither in vivo nor in vitro studies. The present research aimed to evaluate the differences in oxysterols levels following exposure to two metabolism disrupting chems. (propylparaben (PP) and triclocarban (TCC)) in the zebrafish model using liquid chromatog. coupled with tandem mass spectrometry (LC-MS/MS). Following exposure to PP and TCC, there were no significant changes in total and individual oxysterols compared with the control group; however, some interesting differences were noticed: 24-OH was detected only in treated zebrafish embryos, as well as the concentrations of 27-OH, which followed a different distribution, with an increase in TCC treated embryos and a reduction in zebrafish embryos exposed to PP at 24 h post-fertilization (hpf). The results of the present study prompt the hypothesis that EDCs can modulate the oxysterol profile in the zebrafish model and that these variations could be potentially involved in the toxicity mechanism of these emerging contaminants.

In this research, a selective, cost-efficient, and highly sensitive Ag nanostructure Surface Enhanced Raman Spectroscopy sensor was developed as a methodol. approach to rapidly detect a targetss-DNA (stx2) in STEC (Shiga toxin-producing Escherichia coli). The Ag nanostructure-based SERS substrate was functionalized by two types of thiols: thiol-ss-DNA for bonding target ss-DNA and 6-Mercapto-1-hexanol for blocking the Ag nanostructure surface. Methylene Blue (MB) was used as a Raman marker to quantify target ss-DNA, as well as a model mol. to characterize the electrodeposited Ag nanostructure SERS substrate. Ag nanostructure SERS substrates showed good sensitivity and repeatability towards MB detection, with a LOD = 0.3158μM, and RSD = 12.48% (at 45 different random points for 0.1μM MB). More importantly, the Ag nanostructure/ss-DNA SERS substrate showed good selectivity towards STEC O157 stx2 target DNA, as well as good linearity and sensitivity towards its detection in a buffer solution The SERS sensors were able to identify target DNA (stx2) in a STEC strain and the study showed proof of principle that SERS substrate has potential as a cost-effective, highly selective, highly sensitive DNA and bacteria sensor without the aid of DNA amplification.

And the article was included in Applied Surface Science in 2022.Recommanded Product: 61-73-4 This article mentions the following:

Flexible superamphiphobic surfaces show significant potential in anti-fouling, flexible electronics, droplet-based microfluidics, etc. However, there is a bottleneck in quickly generating pliable superamphiphobic surfaces with high liquid repellency and practicability. Here, a new method was proposed to create a superamphiphobic surface with high and durable liquid repellency by effortlessly one-step spraying the fluorinated TiO₂ nanoparticles onto the polymer paper. Even 90 vol% ethanol solution could keep the Cassie state on the surface. The adhesion strengthening of the nanoparticles agglomerates on the paper’s wires generated excellent robustness for resisting underwater ultrasonic shock, resulting in a failure time 2000-times longer than the smooth substrate. No significant degeneration of the paper was observed after storing for 90 days, bending for 1000 cycles, or heating at 200°C. Because of the attractive figurability, the paper could quickly fit on curved surfaces or internal walls. As a proof of concept, the superamphiphobic paper was successfully used for deformable anti-corrosion shelter and droplet-based anal. platform. This work opens a new avenue for accomplishing the long-sort task of efficiently fabricating flexible superamphiphobic surfaces with high comprehensive performances.
