In 2022,Nepal, Prabin; Kalapugama, Suneth; Shevlin, Michael; Naber, John R.; Campeau, Louis-Charles; Pezzetta, Cristofer; Carlone, Armando; Cobley, Christopher J.; Bergens, Steven H. published an article in ACS Catalysis. The title of the article was 《Polycationic Rh-JosiPhos Polymers Supported on Phosphotungstic Acid/Al2O3 by Multiple Electrostatic Attractions》.Electric Literature of C43H72Cl2P2Ru The author mentioned the following in the article:

Cationic Rh-JosiPhos complexes were tethered to crowded, ring-opening olefin metathesis (ROMP)-active norbornene groups. These monomers underwent facile, alternating ROMP (alt-ROMP) with cyclooctene as the co-monomer catalyzed by RuCl2(:CHPh)(PCy3)2 to form linear, polycationic copolymers. The polymers were readily absorbed by phosphotungstic acid (PTA) on Al2O3 via multiple electrostatic attractions between the cationic Rh centers in the polymer and the PTA anions on the Al2O3 support. The enantioselective hydrogenation of di-Me itaconate occurred with 100% conversion, 5000 turnovers per run, with up to 96% ee, and without significant Rh leaching over 10 reuses of the catalyst. The results came from multiple reactions, including the reaction of Benzylidenebis(tricyclohexylphosphine)dichlororuthenium(cas: 172222-30-9Electric Literature of C43H72Cl2P2Ru)

Benzylidenebis(tricyclohexylphosphine)dichlororuthenium(cas: 172222-30-9) is the first metathesis catalyst to be widely used in organic synthesis.

Application In Synthesis of Benzylidenebis(tricyclohexylphosphine)dichlororutheniumIn 2022 ,《Polymers from organosilicon derivatives of 5-norbornene-2-methanol for membrane gas separation》 appeared in Polymer. The author of the article were Adreyanov, Fedor A.; Alentiev, Dmitry A.; Lunin, Artyom O.; Borisov, Ilya L.; Volkov, Alexey V.; Finkelshtein, Eugene Sh; Ren, Xiang-Kui; Bermeshev, Maxim V.. The article conveys some information:

In this work, we have proposed a new strategy to the synthesis of norbornene-type monomers with Si-O-C structural motifs via a straightforward and selective dehydrogenative addition reaction between 5-norbornene-2-methanol and trialkylsilanes. As a result, a set of monomers with various trilalkylsiloxy groups (alkyl – CH3, C2H5, and n-C3H7) was synthesized with the yields of 89-90%. These monomers exhibited a high reactivity in both metathesis and vinyl-addition polymerization, affording high-mol.-weight products in yields up to 90%. The metathesis polymers were rubbery with glass transition temperatures from -29 to +23°C, while related isomeric vinyl-addition polynorbornenes were glassy polymers. Permeability (P) and diffusion (D) coefficients for these polymers were systematically evaluated for permanent gases (He, H2, O2, N2, and CO2) and C1-C4 alkanes. Studying their gas transport properties allowed to establish new structure-property relationships. Particularly, the length of alkyl fragments in trilalkylsiloxy group affected differently gas permeability of metathesis (rubbery) and vinyl-addition (glassy) polymers. Besides, it was shown that the method of linking the Si-O-C-containing group to the main chains of polymers played very important role: Alk3SiO-substituted polynorbornenes are more permeable than isomeric (AlkO)Alk2Si-substituted ones. For the metathesis polynorbornenes, P(CO2) were in the range of 152-226 Barrer, and ideal selectivity (α) of CO2/N2 – 13-16; for the vinyl-addition polynorbornenes, P(CO2) = 230-500 Barrer, and α(CO2/N2) = 14-17. Among studied polymers, promising results for ethane/methane separation was demonstrated by metathesis polynorbornene bearing tri(n-propyl)siloxymethyl substituents: P(C2H6) = 138 Barrer and α(C2H6/CH4) = 2.4. The obtained polymers were also characterized by using TGA, WAXD, and nitrogen adsorption-desorption methods. The experimental part of the paper was very detailed, including the reaction process of Benzylidenebis(tricyclohexylphosphine)dichlororuthenium(cas: 172222-30-9Application In Synthesis of Benzylidenebis(tricyclohexylphosphine)dichlororuthenium)

《Highly efficient three-dimensional solar evaporator for high salinity desalination by localized crystallization》 was written by Wu, Lei; Dong, Zhichao; Cai, Zheren; Ganapathy, Turga; Fang, Niocholas X.; Li, Chuxin; Yu, Cunlong; Zhang, Yu; Song, Yanlin. COA of Formula: ClNaThis research focused onwater film solar evaporator salinity desalination crystallization surface morphol. The article conveys some information:

Abstract: Solar-driven water evaporation represents an environmentally benign method of water purification/desalination. However, the efficiency is limited by increased salt concentration and accumulation. Here, we propose an energy reutilizing strategy based on a bio-mimetic 3D structure. The spontaneously formed water film, with thickness inhomogeneity and temperature gradient, fully utilizes the input energy through Marangoni effect and results in localized salt crystallization Solar-driven water evaporation rate of 2.63 kg m-2 h-1, with energy efficiency of >96% under one sun illumination and under high salinity (25 wt% NaCl), and water collecting rate of 1.72 kg m-2 h-1 are achieved in purifying natural seawater in a closed system. The crystalized salt freely stands on the 3D evaporator and can be easily removed. Addnl., energy efficiency and water evaporation are not influenced by salt accumulation thanks to an expanded water film inside the salt, indicating the potential for sustainable and practical applications.
