Formula: C15H17ClFNO4S《Chinese medicine formula Kai-Xin-San ameliorates neuronal inflammation of CUMS-induced depression-like mice and reduces the expressions of inflammatory factors via inhibiting TLR4/IKK/NF-κB pathways on BV2 cells》 was published in 2021. The authors were Qu, Suchen;Liu, Mengqiu;Cao, Cheng;Wei, Chongqi;Meng, Xue-Er;Lou, Qianyin;Wang, Bin;Li, Xuan;She, Yuyan;Wang, Qingqing;Song, Zhichao;Han, Zhengxiang;Zhu, Yue;Huang, Fei;Duan, Jin-Ao, and the article was included in《Frontiers in Pharmacology》. The author mentioned the following in the article:

Kai-Xin-San (KXS) is a traditional Chinese medicinal formula composed of Ginseng Radix et Rhizoma, Polygalae Radix, Acori Tatarinowii Rhizoma, and Poria for relieving major depressive disorder and Alzheimer’s disease in traditional Chinese medicine (TCM) clinics. Previous studies on the antidepressant mechanism of KXS mainly focused on neurotransmitter and neurotrophic factor regulation, but few reports exist on neuronal inflammation regulation. In the current study, we found that KXS exerted antidepressant effects in chronic unpredictable mild stress-induced depression-like mice according to the results of behavioral tests. Meanwhile, KXS also inhibited the activation of microglia and significantly reduced the expression of pro-inflammatory cytokines such as IL-1β, IL-2, and TNF-α in the hippocampus of mice. In mice BV2 microglia cell lines, KXS extract reduced the expression of inflammatory factors in BV2 cells induced by lipopolysaccharide via inhibiting TLR4/IKK/NF-κB pathways, which was also validated by the treatment of signaling pathway inhibitors such as TAK-242 and JSH-23. T0hese data implied that the regulation of pro-inflammatory cytokines in microglia might account for the antidepressant effect of KXS, thereby providing more scientific information for the development of KXS as an alternative therapy for major depressive disorder. To complete the study, the researchers used (R)-Ethyl 6-(N-(2-chloro-4-fluorophenyl)sulfamoyl)cyclohex-1-enecarboxylate (cas: 243984-11-4) .

Harris, Kenneth R. published 《Thermodynamic or density scaling of the electrical conductivity of molten salts》 in 2022. The article was appeared in 《Journal of Chemical Physics》. They have made some progress in their research.SDS of cas: 7791-11-9 The article mentions the following:

Thermodn. or d. scaling of high-pressure conductivities and molar conductivities of the high-temperature molten salts NaOH, and the alkali chlorides, bromides, and nitrates, from Na to Cs, taken from the literature, is found to be consistent with the simulations of Knudsen, Niss, and Bailey (KNB). They used a simple model fluid of point particles interacting through an interionic potential with a repulsive inverse power law part varying as r^-9 and an attractive Coulombic part. This yields values between the limits 0.33-3 for the scaling parameter, γ. The Coulombic potential reduces the scaling parameter to values much lower than are normally found for mol. liquids, and KNB used this to explain the low values typically found for ionic liquids Here, it is shown that the high-temperature molten salts examined behave similarly.

Category: chlorides-buliding-blocksIn 2022, Laing, Craig C.;Shen, Jiahong;Quintero, Michael A.;Weiss, Benjamin E.;Xia, Yi;Li, Zhi;He, Jiangang;Wolverton, Chris;Kanatzidis, Mercouri G. published 《Homologous Alkali Metal Copper Rare-Earth Chalcogenides A₂Cu_2nLn₄Q_7+n (n = 1, 2, 3)》. 《Chemistry of Materials》published the findings. The article contains the following contents:

Twenty-seven new members of the A₂Cu_2nLn₄Q_7+n (A = Cs, Rb; Ln = La-Nd, Sm, Gd-Yb; Q = S, Se) homologous series were synthesized in one of three structural types (indicated by n = 1, 2, 3). All the compounds contained 3-dimensional frameworks with alkali metal-containing tunnels. For each increment in n, one Cu₂Q was added, which was incorporated into the framework as an edge-sharing tetrahedron by replacing a square planar chalcogenide site. High-throughput DFT calculations predicted many of the phases to be thermodynamically stable. These predictions were compared with the synthesis results for the phases formed in each composition space. In the syntheses, heavier lanthanides showed a preference to start forming the n = 3 ACu₃Ln₂Q₅, which is consistent with the predictions. RbCuNd₂Se₄ and RbCuTb₂Se₄ are thermally stable under vacuum at temperatures up to 1000°. Optical measurements revealed bandgaps of 1.55(5) and 1.62(5) eV for CsCuCe₂Se₄ and RbCuTb₂Se₄, resp., and a work function of 4.83(5) eV for CsCuPr₂Se₄. Addnl., some n = 3 ACu₃Ln₂Q₅ compounds exhibit a neg. phonon mode due to a Cu atom coordination, which may distort to a trigonal planar geometry at sufficiently low temperatures The dynamic instabilities and the predicted distortion in the Cu tetrahedra for the n = 3 ACu₃Ln₂Q₅ compounds have a linear relation with the at. number of the lanthanides and the electronegativity of the lanthanides. The A₂Cu_2nLn₄Q_7+n compounds can potentially find application as high-temperature thermoelec. materials and other semiconductors. To complete the study, the researchers used Rubidiumchloride (cas: 7791-11-9) .

The research results were published in《Advanced Functional Materials》 in 2021.Safety of Rubidiumchloride The article conveys some information:

All-inorganic bismuth-halide perovskites are promising alternatives for lead halide perovskites due to their admirable chem. stability and optoelectronic properties; however, these materials deliver inferior photoluminescence (PL) properties, severely hindering their prospects in lighting applications. Here, a novel air-stable but non-emissive perovskite Rb₃BiCl₆ is synthesized, and the material is used as a prototype to uncover origin of the poor optical performance in bismuth-halide perovskite. It is found that the extremely strong exciton-phonon interactions with a large coupling constant up to 693 meV leads to the seriously nonradiative recombination, which, however, can be effectively suppressed to 347 meV by introducing Sb³⁺ ions. As a result, Sb³⁺-doped Rb₃BiCl₆ exhibits a stable yellow emission with unprecedented PL quantum yield up to 33.6% from self-trapped excitons. Systematic spectroscopic characterizations and theor. calculations are carried out to unveil the intriguing photophys. mechanisms. This work reveals the effect of exciton-phonon interaction, that is often underemphasized, on a material’s photophys. properties. And Rubidiumchloride (cas: 7791-11-9) was used in the research process.

Liu, Minghui;Wei, Changgeng;Zhuzhang, Hangyu;Zhou, Jingmin;Pan, Zhiming;Lin, Wei;Yu, Zhiyang;Zhang, Guigang;Wang, Xinchen published 《Fully Condensed Poly(Triazine Imide) Crystals: Extended π-Conjugation and Structural Defects for Overall Water Splitting》. The research results were published in《Angewandte Chemie, International Edition》 in 2022.Reference of Rubidiumchloride The article conveys some information:

Conventional polymerization for the synthesis of carbon nitride usually generates amorphous heptazine-based melon with an abundance of undesired structural defects, which function as charge carrier recombination centers to decrease the photocatalytic efficiency. Herein, a fully condensed poly(triazine imide) crystal with extended π-conjugation and deficient structure defects was obtained by conducting the polycondensation in a mild molten salt of LiCl/NaCl. The m.p. of the binary LiCl/NaCl system is around 550°, which substantially restrain the depolymerization of triazine units and extend the π-conjugation. The optimized polymeric carbon nitride crystal exhibits a high apparent quantum efficiency of 12% (λ=365 nm) for hydrogen production by one-step excitation overall water splitting, owing to the efficient exciton dissociation and the subsequent fast transfer of charge carriers. To complete the study, the researchers used Rubidiumchloride (cas: 7791-11-9) .

SDS of cas: 7791-11-9In 2021, Chen, Qian;He, Zhiguo;Zhuo, Yuting;Li, Shuzhen;Yang, Wenjing;Hu, Liang;Zhong, Hui published 《Rubidium chloride modulated the fecal microbiota community in mice》. 《BMC Microbiology》published the findings. The article contains the following contents:

The microbiota plays an important role in host health. Although rubidium (Rb) has been used to study its effects on depression and cancers, the interaction between microbial commensals and Rb is still unexplored. To gain the knowledge of the relationship between Rb and microbes, 51 mice receiving RbCl-based treatment and 13 untreated mice were evaluated for their characteristics and bacterial microbiome changes. The 16S rRNA gene sequencing of fecal microbiota showed that RbCl generally maintained fecal microbial community diversity, while the shifts in fecal microbial composition were apparent after RbCl exposure. RbCl significantly enhanced the abundances of Rikenellaceae, Alistipes, Clostridium XlVa and sulfate-reducing bacteria including Deltaproteobacteria, Desulfovibrionales, Desulfovibrionaceae and Desulfovibrio, but significantly inhibited the abundances of Tenericutes, Mollicutes, Anaeroplasmatales, Anaeroplasmataceae and Anaeroplasma lineages. With regarding to the archaea, we only observed two less richness archaea Sulfolobus and Acidiplasma at the genus level. Changes of fecal microbes may in part contribute to the anticancer or anti-depressant effects of RbCl. These findings further validate that the microbiome could be a target for therapeutic intervention.Rubidiumchloride (cas: 7791-11-9) were involved in the experimental procedure.

Application In Synthesis of (1S)-4,7,7-Trimethyl-3-oxo-2-oxabicyclo[2.2.1]heptane-1-carbonyl chloride(Chunks or pellets)《Iterative design of a helically folded aromatic oligoamide sequence for the selective encapsulation of fructose》 was published in 2015. The authors were Chandramouli, Nagula;Ferrand, Yann;Lautrette, Guillaume;Kauffmann, Brice;MacKereth, Cameron David;Laguerre, Michel;Dubreuil, Didier;Huc, Ivan, and the article was included in《Nature Chemistry》. The author mentioned the following in the article:

The ab initio design of synthetic mol. receptors for a specific biomol. guest remains an elusive objective, particularly for targets such as monosaccharides, which have very close structural analogs. Here we report a powerful approach to produce receptors with very high selectivity for specific monosaccharides and, as a demonstration, we develop a foldamer that selectively encapsulates fructose. The approach uses an iterative design process that exploits the modular structure of folded synthetic oligomer sequences in conjunction with mol. modeling and structural characterization to inform subsequent refinements. Starting from a first-principles design taking size, shape and hydrogen-bonding ability into account and using the high predictability of aromatic oligoamide foldamer conformations and their propensity to crystallize, a sequence that binds to β-D-fructopyranose in organic solvents with at.-scale complementarity was obtained in just a few iterative modifications. This scheme, which mimics the adaptable construction of biopolymers from a limited number of monomer units, provides a general protocol for the development of selective receptors.(1S)-4,7,7-Trimethyl-3-oxo-2-oxabicyclo[2.2.1]heptane-1-carbonyl chloride(Chunks or pellets) (cas: 39637-74-6) were involved in the experimental procedure.

J.;Hines, Adrian T.;Besmann, Theodore M.;zur Loye, Hans-Conrad, and the article was included in《Inorganics》. The author mentioned the following in the article:

A new niobium-doped inorganic scintillating oxyfluoride, Rb₄Ge₅O₉F₆:Nb, was synthesized in single crystal form by high-temperature flux growth. The host structure, Rb₄Ge₅O₉F₆, crystallizes in the orthorhombic space group Pbcn with lattice parameters a = 6.98430(10) Å, b = 11.7265(2) Å, and c = 19.2732(3) Å, consisting of germanium oxyfluoride layers made up of Ge₃O₉ units connected by GeO₃F₃ octahedra. In its pure form, Rb₄Ge₅O₉F₆ shows neither luminescence nor scintillation but when doped with niobium, Rb₄Ge₅O₉F₆:Nb exhibits bright blue luminescence and scintillation. The isostructural doped structure, Rb₄Ge₅O₉F₆:Nb, crystallizes in the orthorhombic space group Pbcn with lattice parameters a = 6.9960(3) Å, b = 11.7464(6) Å, and c = 19.3341(9) Å. X-ray absorption near edge structure (XANES) and extended X-ray absorption fine structure (EXAFS) measurements suggest that the niobium is located in an octahedral coordination environment. Optical measurements inform us that the niobium dopant acts as the activator. The synthesis, structure, and optical properties are reported, including radioluminescence (RL) measurements under X-ray irradiation And Rubidiumchloride (cas: 7791-11-9) was used in the research process.

The research results were published in《Advanced Electronic Materials》 in 2022.Related Products of 7791-11-9 The article conveys some information:

Memristors are one of the fastest developing electronic devices in the field of data storage and brain inspired neural computing. As a two terminal device, memristors are numerously utilized as resistive random access memories (RRAM) and energy efficient artificial synapses. Herein, the fabrication of perovskite-type rubidium lead chloride quantum dots (RPCQDs) is reported as a functional layer in a memristive system. The device, Al/RPCQDs/indium doped tin oxide (ITO), exhibits a cycling-induced decrease in SET voltage, where Al and ITO work as a top and bottom electrode resp. However, time dependent self-recovery to the pristine state is observed in the Al/RPCQDs/ITO device. In contrast, the self-rejuvenation is suppressed when a buffer capped conducting polymer (BCCP) is incorporated on the ITO layer to make a Al/RPCQDs/BCCP/ITO structure. This customized device structure successfully retains the reproducible bipolar switching behavior without severe deviation in operating voltages, which helps in studying reliable memristive properties. In addition, the Al/RPCQDs/BCCP/ITO memristive device also demonstrates some essential synaptic functions such as pair-pulse facilitation, long-term potentiation, and long-term depression. The experimental procedure involved many compounds, such as Rubidiumchloride (cas: 7791-11-9) .
