Fabrication of novel heterogeneous catalysts with well-designed structures is unusually intriguing for CO2 conversion. In this study, we have prepared a porous hollow N-doped carbon tube through the pyrolysis of self-assembled melamine cyanurate aggregate supramol. precursor. Ultrasmall Ag nanoparticles were tightly anchored in the hollow N-doped carbon tube via an in-situ fabrication. The average size of Ag nanoparticles was confined in only 2.19 nm with the assistance of abundant surface functional groups and porous structures. Addnl., inherent hollow N-doped carbon tube structure could prevent nanoparticles aggregating and leaching; also, they facilitated gas adsorption and mass transfer in CO2 catalysis. Due to their remarkable properties, the novel material was utilized as heterogeneous catalyst for the carboxylation of alkynes with CO2, and exhibited outstanding catalytic activity and stability at ambient pressure and low temperature

Liang, He; Yin, Jie; Man, Kenny; Yang, Xuebin B.; Calciolari, Elena; Donos, Nikolaos; Russell, Stephen J.; Wood, David J.; Tronci, Giuseppe published the artcile< A long-lasting guided bone regeneration membrane from sequentially functionalised photoactive atelocollagen>, Safety of 1-(Chloromethyl)-4-vinylbenzene, the main research area is bone regeneration membrane photoactive atelocollagen; Atelocollagen; Barrier membrane; Enzymatic stability; Guided Bone Regeneration; Sequential functionalisation; UV curing.

The fast degradation of collagen-based membranes in the biol. environment remains a critical challenge, resulting in underperforming Guided Bone Regeneration (GBR) therapy leading to compromised clin. results. Photoactive atelocollagen (AC) systems functionalised with ethylenically unsaturated monomers, such as 4-vinylbenzyl chloride (4VBC), have been shown to generate mech. competent materials for wound healing, inflammation control and drug delivery, whereby control of the mol. architecture of the AC network is key. Building on this platform, the sequential functionalisation with 4VBC and methacrylic anhydride (MA) was hypothesised to generate UV-cured AC hydrogels with reduced swelling ratio, increased proteolytic stability and barrier functionality for GBR therapy. The sequentially functionalised atelocollagen precursor (SAP) was characterised via TNBS and ninhydrin colorimetric assays, CD and UV-curing rheometry, which confirmed nearly complete consumption of collagen′s primary amino groups, preserved triple helixes and fast (< 180 s) gelation kinetics, resp. Hydrogel′s swelling ratio and compression modulus were adjusted depending on the aqueous environment used for UV-curing, while the sequential functionalisation of AC successfully generated hydrogels with superior proteolytic stability in vitro compared to both 4VBC-functionalised control and the com. dental membrane Bio-Gide. These in vitro results were confirmed in vivo via both s.c. implantation and a proof-of-concept study in a GBR calvarial model, indicating integrity of the hydrogel and barrier defect, as well as tissue formation following 1-mo implantation in rats. Collagen-based membranes remain a key component in Guided Bone Regeneration (GBR) therapy, but their properties, e.g. proteolytic stability and soft tissue barrier functionality, are still far from optimal. This is largely attributed to the complex mol. configuration of collagen, which makes chem. accessibility and structure-function relations challenging. Here, we fabricated a UV-cured hydrogel network of atelocollagen, whereby triple helixes were sequentially functionalised with two distinct ethylenically unsaturated monomers. The effects of the sequential functionalisation and UV-curing on the macroscopic properties, degradation behavior and GBR capability were investigated in vitro and in vivo. The results highlight the key role of the sequential functionalisation and provide important insights for the design of future, longer-lasting resorbable membranes for GBR therapy.

Wei, Bo; Sun, Jianfei; Mei, Qiong; An, Zexiu; Wang, Xueyu; Cao, Haijie; Han, Dandan; He, Maoxia published the artcile< Feasibility of carbon-doped BN nanosheets as photocatalyst for degradation of 4-chloroguaiacol and ecotoxicity fate during indirect photochemical transformation>, Recommanded Product: 4-Chloro-2-methoxyphenol, the main research area is chloroguaiacol water degradation oxidation photocatalyst carbon boron nitride ecotoxicity.

Although carbon-doped BN nanosheet (BCN) has been successfully synthesized and used, it has not been reported as a photocatalyst for the degradation of organic pollutants. In this study, 4-chloroguaiacol (4-CG) was selected as a representative substance to investigate the potential of utilizing BCN as photocatalyst for organic removal by use of computational simulation. The adsorption mechanisms, degradation mechanisms, and kinetics of 4-CG with the presence of different catalysts were determined The adsorption energy of 4-CG on BCN was 10.71 kcal mol-1, and the ΔG≠s of initial reactions of 4-CG with ·OH were also reduced onto the BCN substrate. The band gap of BCN was 1.54 eV. Our computations depicted that the doping of aromatic carbon into BN narrows bandgap, and retains well catalytic performance and adsorption properties. Therefore, BCN nanosheet is a promising photocatalyst for organic pollutants removal. Possible degradation pathways of 4-CG and aquatic toxicity assessment during degradation were also carried out. More toxic products would be formed and the transformation products were still harmful to three trophic levels of aquatic organisms (fish, green algae, and daphnia).

Materials & methods: Fifty-one novel 12N-substituted matrinic acid derivatives were synthesized and evaluated for their anti-coxsackievirus B3 activities. Results: Structure-activity relationship studies revealed that the 11-side chain could be determinant for the selectivity index by adjusting overall lipophilicity, and 11-butane was the best one for both potency and druggability. The optimized 35d showed the broad-spectrum anti-coxsackieviruse effects, an excellent pharmacokinetics and a good safety profile. More importantly, it displayed a potential effect for the pleconaril-resistant coxsackievirus B3 as well. Its mode of action is targeting on the viral transcription and translation stage, a different mechanism from that of pleconaril. Conclusion: Thus, we considered that 35d is a promising anti-enteroviral candidate for the treatment of various diseases infected with coxsackieviruses.

Energy band structures greatly determine the charge separation and transfer properties in heterojunction photocatalysts and consequently their photocatalytic activities. Herein, a well-designed Z-scheme ZnIn2S4-S/CNTs/RP (ZIS-S/CNTs/RP) nanocomposite was fabricated according to an energy band alignment steering strategy to realize superior photocatalytic H2 evolution performance. The ZIS-S/CNTs/RP nanocomposite shows an efficient photocatalytic H2 evolution rate of 1639.9μmol g-1h-1, which is noticeably higher than that of pristine red phosphorus (RP) and CNTs/RP and ZIS-S/RP composites, as well as those of the compared heterojunctions using bulk RP or ZnIn2S4. Owing to the modification of nanosized RP and the introduction of sulfur vacancies in ZnIn2S2, a tailored energy band alignment of the heterojunction with a higher reduction potential and larger Fermi level p.d. was achieved, which resulted in significantly increased photogenerated electron-hole separation efficiency and a more efficient Z-scheme charge transfer mechanism, thus promoting the photocatalytic activity of ZIS-S/CNTs/RP. This work aims to provide a novel effective strategy for the construction of high-performance heterojunction photocatalysts by energy band engineering.
