Aly, Nesma published the artcileCosmetic Potential of a Recombinant 50 kDa Protein, Category: alcohols-buliding-blocks, the publication is Cosmetics (2022), 9(1), 8, database is CAplus.

Collagen and its derivative proteins have been widely used as a major component for cosmetic formulations as a natural ingredient and moisturizer. Most com. available collagens are animal-derived collagen type I and other forms of collagen, such as type III collagen, are far less prevalent in animals, making extraction and purification extremely difficult and expensive. Here, we report the production of a 50 kDa protein produced in yeast that is 100% identical to the N-terminus of the human type III collagen. This recombinant protein has a larger mol. weight than most incumbent recombinant collagen proteins available for personal care applications. We report the industrialization of both the fermentation and purification processes to produce a final recombinant protein product. This final protein product was shown to be safe for general applications to human skin and compatible with common formulation protocols, including ethanol-based formulations. This recombinant collagen type III protein was also shown to uniquely stimulate both collagen type I and type III production and secretion by primary human dermal fibroblasts. The unique combination of biostimulation, compatibility with beauty product formulations and demonstrated com. production, make this novel recombinant type III collagen a good candidate for broad application in the cosmetics industry.

Huang, Huan-Ming published the artcileRadical Carbonyl Umpolung Arylation via Dual Catalysis, SDS of cas: 111-29-5, the publication is Journal of the American Chemical Society (2022), 144(4), 1899-1909, database is CAplus and MEDLINE.

A series of aryl benzoates I [R = iPr, tBu, cyclohexyl, etc.; R¹ = 4-NCC₆H₄, 2-NCC₆H₄, 2-pyridyl, etc.] via dual nickel and photoredox catalyzed radical carbonyl umpolung arylation of aldehydes and aryl bromides was reported. This redox-neutral approach provided a complementary method to construct Grignard-type products from (hetero)aryl bromides and aliphatic aldehydes, without the need for prefunctionalization. Sequential activation, hydrogen atom transfer and halogen atom transfer process could directly converted aldehydes to the corresponding ketyl radicals, which further react with aryl-nickel intermediates in an overall polarity-reversal process. This radical strategy tolerated-among others-acidic functional groups, heteroaryl motifs and sterically hindered substrates and was applied in the late-stage modification of drugs and natural products.

Van de Voorde, Babs published the artcilePotential of poly(alkylene terephthalate)s to control endothelial cell adhesion and viability, Related Products of alcohols-buliding-blocks, the publication is Materials Science & Engineering, C: Materials for Biological Applications (2021), 112378, database is CAplus and MEDLINE.

Poly(ethylene terephthalate) (PET) is known for its various useful characteristics, including its applicability in cardiovascular applications, more precisely as synthetic bypass grafts for large diameter (â‰?6 mm) blood vessels. Although it is widely used, PET is not an optimal material as it is not interactive with endothelial cells, which is required for bypasses to form a complete endothelium. Therefore, in this study, poly(alkylene terephthalate)s (PATs) have been studied. They were synthesized via a single-step solution polycondensation reaction, which requires mild reaction conditions and avoids the use of a catalyst or additives like heat stabilizers. A homologous series was realized in which the alkyl chain length varied from 5 to 12 methylene groups (n = 5-12). Molar masses up to 28,000 g/mol were obtained, while various odd-even trends were observed with modulated differential scanning calorimetry (mDSC) and rapid heat-cool calorimetry (RHC) to access the thermal properties within the homologous series. The synthesized PATs have been subjected to in vitro cell viability assays using Human Umbilical Vein Endothelial Cells (HUVECs) and Human Dermal Microvascular Endothelial Cells (HDMECs). The results showed that HUVECs adhere and proliferate most pronounced onto PAT(n = 9) surfaces, which could be attributed to the surface roughness and morphol. as determined by at. force microscopy (AFM) (i.e. R_q = 204.7 nm). HDMECs were investigated in the context of small diameter vessels and showed superior adhesion and proliferation after seeding onto PAT_(n ₌ ₆₎ substrates. These preliminary results already pave the way towards the use of PAT materials as substrates to support endothelial cell adhesion and growth. Indeed, as superior endothelial cell interactivity compared to PET was observed, time-consuming and costly surface modifications of PET grafts could be avoided by exploiting this novel material class.

Rodiansono published the artcileUnravelling the one-pot conversion of biomass-derived furfural and levulinic acid to 1,4-pentanediol catalysed by supported Raney Ni-Sn alloy catalysts, Computed Properties of 111-29-5, the publication is RSC Advances (2022), 12(1), 241-250, database is CAplus and MEDLINE.

Bimetallic Ni-Sn alloys have been recognized as promising catalysts for the transformation of furanic compounds and their derivatives into valuable chems. Herein, we report the utilization of a supported bimetallic RANEY nickel-tin alloy supported on aluminum hydroxide (RNi-Sn(x)/AlOH; x is Ni/Sn molar ratio) catalysts for the one-pot conversion of biomass-derived furfural and levulinic acid to 1,4-pentanediol (1,4-PeD). The as prepared RNi-Sn(1.4)/AlOH catalyst exhibited the highest yield of 1,4-PeD (78%). The reduction of RNi-Sn(x)/AlOH with H₂ at 673-873 K for 1.5 h resulted in the formation of Ni-Sn alloy phases (e.g., Ni₃Sn and Ni₃Sn₂) and caused the transformation of aluminum hydroxide (AlOH) to amorphous alumina (AA). The RNi-Sn(1.4)/AA 673 K/H₂ catalyst contained a Ni₃Sn₂ alloy as the major phase, which exhibited the best yield of 1,4-PeD from furfural (87%) at 433 K, H₂ 3.0 MPa for 12 h and from levulinic acid (up to 90%) at 503 K, H₂ 4.0 MPa, for 12 h. Supported RANEY Ni-Sn(1.5)/AC and three types of supported Ni-Sn(1.5) alloy (e.g., Ni-Sn(1.5)/AC, Ni-Sn(1.5)/c-AlOH, and Ni-Sn(1.5)/γ-Al₂O₃) catalysts afforded high yields of 1,4-PeD (65-87%) both from furfural and levulinic acid under the optimized reaction conditions.

Aubrey, Michael L. published the artcileDependence of Linker Length and Composition on Ionic Conductivity and Lithium Deposition in Single-Ion Conducting Network Polymers, Formula: C5H12O2, the publication is Macromolecules (Washington, DC, United States) (2021), 54(16), 7582-7589, database is CAplus.

Single-ion conducting electrolytes stand as promising alternatives to state-of-the-art electrolytes in lithium batteries, although a single-ion conducting material with high Li⁺ conductivity, stability in contact with lithium, and suitable mech. properties has been slow to emerge. Here, we describe the synthesis of a series of single-ion conducting network polymers from the reaction of tetrakis(4-(chloromethyl)-2,3,5,6-tetrafluorophenyl)borate with oligoethylene glycoxide linkers Li₂O[(CH₂CH₂)O]_n (n = 1, 2, 3, 9, and 22). Polymers with the longest linkers (n = 9 and 22; ANP-9 and ANP-10, resp.) form materials with conductivities of ~10^-6 S cm^-1 at 100°C. With the addition of 65 wt % propylene carbonate (PC), all the network polymers in the series exhibit high conductivities at ambient temperatures, with the n = 1 material (ANP-6) achieving a bulk ionic conductivity of 2.5 × 10^-4 S cm^-1 at 25°C. More conductive single-ion conducting gels could be prepared by using the less coordinating pentanediol dilithium salt as a linker (ANP-11; σ = 3.5 × 10^-4 S cm^-1 at 25°C), although this material exhibited a surprisingly high interfacial resistance in contact with a lithium electrode. In contrast, the gel formed with ANP-6 is notably stable in contact with metallic lithium electrodes, displays a lithium-ion transference number of unity, and boasts a wide electrochem. stability window of greater than 4.5 V. Temperature-dependent ac impedance anal. reveals that the ionic conductivity of this material-and likely the other gels in the series-matches closely to a Vogel-Tamman-Fulcher temperature model.

Saleemi, Sidra published the artcileBio-Inspired Hierarchical Carbon Nanotube Yarn with Ester Bond Cross-Linkages towards High Conductivity for Multifunctional Applications, Computed Properties of 111-29-5, the publication is Nanomaterials (2022), 12(2), 208, database is CAplus and MEDLINE.

The cross-linked hierarchical structure in biol. systems provides insight into the development of innovative material structures. Specifically, the sarcoplasmic reticulum muscle is able to transmit elec. impulses in skeletal muscle due to its cross-linked hierarchical tubular cell structure. Inspired by the cross-linked tubular cell structure, we designed and built chem. cross-links between the carbon nanotubes within the carbon nanotube yarn (CNT yarn) structure by an esterification reaction. Consequently, compared with the pristine CNT yarn, its elec. conductivity dramatically enhanced 348%, from 557 S/cm to 1950 S/cm. Furthermore, when applied with three voltages, the electro-thermal temperature of esterified CNT yarn reached 261°C, much higher than that of pristine CNT yarn (175°C). In addition, the esterified CNT yarn exhibits a linear and stable piezo-resistive response, with a 158% enhanced gauge factor (the ratio of elec. resistance changing to strain change ∼1.9). The superconductivity, flexibility, and stable sensitivity of the esterified flexible CNT yarn demonstrate its great potential in the applications of intelligent devices, smart clothing, or other advanced composites.

Shubhashish, Shubhashish published the artcileSynthesis of Highly Porous Metal Oxide Nanoparticles for Adsorption Applications, HPLC of Formula: 111-29-5, the publication is ACS Applied Nano Materials (2022), 5(5), 7078-7091, database is CAplus.

Herein, we report a general and straightforward synthesis method for large-pore highly mesoporous metal oxide nanoparticles via a modified inverse micelle formation. The role of diols as solvents has been demonstrated and extended to other metal oxides using ethylene glycol. After scanning most of the metals from the periodic table, magnesium and calcium from the s-block; tin from the p-block; vanadium, nickel, zinc, zirconium, and hafnium from the d-block; and lanthanum and cerium from the f-block elements, all these have been successfully synthesized as large-pore-diameter metal oxides. Because of thermodn. stability of chelate formation, ethylene glycol, 1,3-propanediol, 1,4-butanediol, and 1,5-pentanediol give a higher pore diameter, whereas a further increase in the diol carbon chain (1,6-hexanediol and 1,12-dodecanediol) leads to pore contraction. By varying the synthesis temperature, the effect of viscosity on the pore diameter has also been demonstrated. Potential applications of oxides of magnesium have been tested for carbon dioxide capture and adsorption of macromols. such as proteins and lipids and small mols. such as curcumin, dopamine, and sucrose. As predicted, larger-pore-diameter and higher-pore-volume mesoporous magnesium oxide shows higher carbon dioxide capture and adsorption compared to com. magnesium oxide. A mechanism for the higher pore diameters of mesoporous metal oxide nanomaterials has been proposed based on the results and previous reported literature studies.

Xie, Zhiyong published the artcileCatalytic activity of nickel and cobalt for amination of ethylene glycol: Which is better?, Synthetic Route of 111-29-5, the publication is Molecular Catalysis (2022), 112243, database is CAplus.

Metal Ni and Co are widely used in the catalytic amination of alcs. and Ni is more favored due to its better catalytic performance. Here we compared their catalytic performance for the amination of ethylene glycol and unexpectedly found that Co is more active than Ni. DFT calculation results showed that the energy barriers for the dissociation of O-H and C-H bond in an ethylene glycol mol. are smaller on Co (0001) plane, accounting for higher ethylene glycol conversion and primary amine yield on metal Co catalyst. The C-C bond dissociation in a glycolaldehyde (dehydrogenation intermediate of ethylene glycol) mol. has significantly lower energy barrier on Ni (111) plane, being consistent with lower selectivity of primary amine on metal Ni catalyst. We also compared their catalytic performance for the amination of other diols and the results showed that Co is more active when short-chain diols are used as the substrate.

Stimulus-responsive supramol. organogels have been broadly studied, but the assembly of a liquid crystalline organogel with a thermoreversible response remains a challenge. This could be attributed to the difficulty of designing organogelators with liquid crystalline properties. Nucleophilic aromatic substitution (S_NAr) has been utilized to produce a diversity of pentafluorobenzene-containing aromatics, which are very regioselective to para positions. Those pentafluorobenzene-functionalized aromatics have been ideal compounds for the preparation of calamitic liquid crystals. In this context, novel fluoroterphenyl-containing main-chain polyether (FTP@PE) was synthesized using in situ S_NAr polymerization as a convenient and effective synthetic strategy toward the development of fluorescent liquid crystals bearing fluoroterphenyl and ether groups. The fluoroterphenyl unit was synthesized by Cu(I)-supported decarboxylation cross-coupling of potassium pentafluorobenzoate and 1,4-diiodobenzene. The chem. structures of FTP@PE were studied with ¹H/¹³C/¹⁹F NMR and IR spectra. The liquid crystal mesophases were determined with differential scanning calorimetry and polarizing optical microscopy. UV-visible absorbance and emission spectral profiles showed solvatochromic activity. The nanofibrous morphologies were studied with a scanning electron microscope. The organogels of FTP@PE were developed in a number of solvents via van der Waals attraction forces of aliphatic moieties and π stacking of fluoroterphenyl groups. They demonstrated thermoreversible responsiveness.

The synthesis of a broad range of enantioenriched amines by the direct Fe-catalyzed coupling of amines with alcs. through the borrowing hydrogen strategy, while at least one of these substrates was achiral is reported. When starting from α-chiral amines and achiral alcs., a wide range of enantioenriched amine products, including N-heterocyclic moieties was obtained with complete retention of stereochem.. The power of this method was demonstrated in the one-step synthesis of known pharmaceuticals from com. available, simple enantiopure primary amines and achiral alcs. It was also found that the use of β-branched enantioenriched primary alcs. and achiral amines as reaction partners leads to a partial loss of stereochem. integrity in the final product, however, a systematic optimization enabled partial retention of enantiopurity and possible parameters effecting for racemization were identified.
