Tuning the product selectivity of SAPO-18 catalysts in MTO reaction via cavity modification

The AEI cavity of SAPO-18 catalyst was modified with zinc cations with the conventional ion exchange procedure.The cavity modification effectively tunes the product selectivity,and shifts the products from mainly propylene to comparable production of ethylene and propylene in methanol to olefin(MTO)reaction.The incorporation of zinc ions and the generation of bicyclic aromatic species in the AEI cavity of SAPO-18 catalysts introduce additional diffusion hindrance that exert greater influence on the relatively bulky products(e.g.propylene and higher olefins),which increase the selectivity to small-sized products(e.g.ethylene).It appears that the incorporated zinc cations facilitate the generation of lower methylbenzenes which promote the generation of ethylene.The cavity modification via incorporating zinc ions effectively tunes the product selectivity over SAPO molecular sieves with relatively larger cavity,which provides a novel strategy to develop the potential alternative to SAPO-34 catalysts for industrial MTO reaction.

Improving electrochemical performance of Ni-rich layered oxide cathodes via one-step dual modification strategy

A one-step overall strategy from surface to bulk was proposed to simultaneously synthesize the Nb-doped and LiNbO_(3)-coated LiNi_(0.83)Co_(0.12)Mn_(0.05)O_(2) cathode materials.The incorporation of LiNbO_(3) coating can regulate the interface and facilitate the diffusion of Li-ions.Simultaneously,the stronger Nb—O bond can effectively suppress Li^(+)/Ni^(2+) cation mixing and strengthen the stability of crystal structure,which helps to mitigate the anisotropic variations of lattice parameters during Li^(+) de/intercalation.The results showed that the dual-modified materials exhibited good structural stability and distinguished electrochemical performance.The optimal NCM-Nb2 sample showed an excellent capacity retention of 90.78%after 100 cycles at 1C rate between 2.7 and 4.3 V,while only 67.90%for the pristine one.Meanwhile,it displayed a superior rate capability of 149.1 mA·h/g at the 10C rate.These results highlight the feasibility of one-step dual modification strategy to synchronously improve the electrochemical performance of Ni-rich layered oxide cathodes.

Defect-assisted surface modification enhances the visible light photocatalytic performance of g-C_3N_4@C-TiO_2 direct Z-scheme heterojunctions

To increase the number of active sites and defects in TiO2 and promote rapid and efficient transfer of photogenerated charges, a g-C3N4@C-TiO2 composite photocatalyst was prepared via in situ deposition of g-C3N4 on a carbon-doped anatase TiO2 surface. The effects of carbon doping state and surface modification of g-C3N4 on the performance of g-C3N4@C-TiO2 composite photocatalysts were studied by X-ray diffraction, X-ray photoelectron spectroscopy, UV-visible diffuse-reflectance spectroscopy, transmission electron microscopy, electrochemical impedance spectroscopy, photoluminescence, and electron paramagnetic resonance. With increasing carbon doping content, the carbon doping state in TiO2 gradually changed from gap to substitution doping. Although the number of oxygen vacancies gradually increased, the degradation efficiency of g-C3N4@C-TiO2 for RhB (phenol) initially increased and subsequently decreased with increasing carbon content. The g-C3N4@10C-TiO2 sample exhibited the highest apparent reaction rate constant of 0.036 min儃1 (0.039 min儃1) for RhB (phenol) degradation, which was 150 (139), 6.4 (6.8), 2.3 (3), and 1.7 (2.1) times higher than that of pure TiO2, 10C-TiO2, g-C3N4, and g-C3N4@TiO2, respectively. g-C3N4 was grown in situ on the surface of C-TiO2 by surface carbon hybridization and bonding. The resultant novel g-C3N4@C-TiO2 photocatalyst exhibited direct Z-scheme heterojunctions with non-local impurity levels. The high photocatalytic activity can be attributed to the synergistic effects of the improved visible light response ability, higher photogenerated electron transfer efficiency, and redox ability arising from Z-type heterojunctions.

Research progress of polysaccharide nanocarriers based on traditional Chinese medicine Thallus japonica

In the last few years,the overall incidence of malignant tumors has been increasing in the country.In order to find effective anti-tumor drugs,the development and modification of natural drugs have become the focus of domestic and international researchers.Thallus japonica,composed of polysaccharides,minerals,amino acids,natural proteins,and lipids,is a traditional Chinese medicine with the functions of eliminating phlegm and disinhibiting water.At the same time,it has the edible and medicinal efficacy.There are a lot of active components that have been demonstrated to possess diverse biological activities including anti-tumor,anti-viral,anti-coagulant,and anti-bacterial,and so on in thallus japonica.Laminarin,composed of glucose,galactose,fucose and so on,is a common and high molecular weight heteropolysaccharide in brown algae(such as thallus japonica,kelp),and it is a potential anti-tumor drug.However,the lack of biological activity of natural polysaccharides limits the application of polysaccharides,so it is necessary to modify the structure or physical and chemical properties of it to enhance the anti-tumor activity of polysaccharides.In recent years,in order to improve the biological activity of laminarin,domestic and international researchers have introduced some groups on the surface of it.Moreover,use the function of modified groups to cause the changes in physicochemical property,spatial structure,substituent group and molecular weight to improve the anti-tumor activity in vitro and in vivo.Therefore,the structural modification has become the main and powerful means to improve the activity of polysaccharides.

First-principles Study on the Electronic Structure of Novel Titanium Yttrium Mixed-metal Nitride Clusterfullerene

We present a first-principles study on the geometric, vibrational and electronic properties of a novel Y-based non-scandium mixed-metal nitride clusterfullerene （TiY2N@C80）. Theoretical results indicate that the fundamental electronic properties of TiY2N@C80 are similar to that of TiSc2N@C80, but dramatically different from that of ScaN@C800 and YaN@C80 molecules. We find that the magnetism of TiY2N@C80 is quenched by carrier doping. The rotation energy barrier of the TiY2N cluster in C80 cage was obviously increased by exohedral chemical modification with pyrrolidine monoadduct.

Construction of 2D Zn‐MOF/BiVO_(4)S‐scheme heterojunction for efficient photocatalytic CO_(2) conversion under visible light irradiation

The construction of S‐scheme heterojunction photocatalysts has been regarded as an effective avenue to facilitate the conversion of solar energy to fuel.However,there are still considerable challenges with regard to efficient charge transfer,the abundance of catalytic sites,and extended light absorption.Herein,an S‐scheme heterojunction of 2D/2D zinc porphyrin‐based metal‐organic frameworks/BiVO_(4)nanosheets(Zn‐MOF/BVON)was fabricated for efficient photocatalytic CO_(2)conversion.The optimal one shows a 22‐fold photoactivity enhancement when compared to the previously reported BiVO4 nanoflake(ca.15 nm),and even exhibits~2‐time improvement than the traditional g‐C3N4/BiVO4 heterojunction.The excellent photoactivities are ascribed to the strengthened S‐scheme charge transfer and separation,promoted CO_(2)activation by the well‐dispersed metal nodes Zn_(2)(COO)_(4)in the Zn‐MOF,and extended visible light response range based on the results of the electrochemical reduction,electron paramagnetic resonance,and in‐situ diffuse reflectance infrared Fourier transform spectroscopy.The dimension‐matched Zn‐MOF/BVON S‐scheme heterojunction endowed with highly efficient charge separation and abundant catalytic active sites contributed to the superior CO2 conversion.This study offers a facile strategy for constructing S‐scheme heterojunctions involving porphyrin‐based MOFs for solar fuel production.

Genetic interactions and modifi er genes in Hirschsprung's disease

Hirschsprung's disease is a congenital disorder that occurs in 1:5000 live births. It is characterised by an absence of enteric neurons along a variable region of the gastrointestinal tract. Hirschsprung's disease is classified as a multigenic disorder, because the same phenotype is associated with mutations in multiple distinct genes. Furthermore, the genetics of Hirschsprung's disease are highly complex and not strictly Mendelian. The phenotypic variability and incomplete penetrance observed in Hirschsprung' s disease also suggests the involvement of modifier genes. Here, we summarise the current knowledge of the genetics underlying Hirschsprung's disease based on human and animal studies, focusing on the principal causative genes, their interactions, and the role of modif ier genes.

XAFS Study of Coordination Structure of Cu（L-His）2 in Solution

Multiple coordination modes are present copper coordination environment varies in the CuII-histidine complex in solution and the with pH. In this work, we have investigated the coordination geometry of Cu（His）2 complex using X-ray absorption fine structure （XAFS） analysis. Copper K-edge XAFS spectra were acquired on aqueous Cu2＋ samples with his- tidine at different pH values. The coordination environments were further confirmed by chemically modified histidine. Results show that the caboxylate groups coordinate at acidic condition, while amino and imidazole nitrogens get coordinated at higher pH. For the co- ordination geometry of Cu（His）2 in solution at physiological pH, the sixfold coordination is preferentially formed, while the fivefold coordination can co-exist in equilibrium.

Ornaments as Means of Efficient Reinforcement in Heritage Buildings

Heritage consists of those items people have inherited and want to keep, as they give them the sense of the past of their cultural identity, but these items, especially the buildings, could not face deteriorations during their period of life, such as the change of loads, the act of the environmental conditions, the effect of the duration time of the materials and the misuse of the occupants. They need special treatments and reinforcements to keep the structural state or to gain extra forces to receive the new loads. But the traditional ways of reinforcement do not prove endless solutions as the most means of the deteriorations from the nature. So, the liability issue is how to find the least reinforcement within the means of technology with the least deterioration and in a less time or by other ways efficiently. The hypothesis considers that the ornaments in some heritage buildings are found in critical levels of the construction which can share in an efficient way in the reinforcement processes of such buildings.

PI3K signaling pathway targeting by using different molecular approaches to treat cancer

Recent evidence of research has been proposed that the phosphoinositide 3-kinase(PI3K) pathway is noticeable target for searching novel anticancer agents. The phosphoinositide 3-kinase(PI3K) is accountable for harmonizing a diverse range of cell functions, such as transcription, proliferation, cell survival, cell growth, degranulation, vesicular trafficking and cell migration, which are mostly involved in carcinogenesis. Particularly, PI3K-mediated signaling molecules and its effects on gene expression contribute to tumorigenesis. PI3Ks generally are grouped into three distinct classes: Ⅰ, Ⅱ and Ⅲ according to their structure and function. The class IA of PI3K includes an alpha, beta or delta p110 catalytic subunit(p110α, p110β, or p110γ), which are associated with the activation of RTKs. Mutations in PIK3CA, the gene encoding the p110α catalytic subunit of PI3K, have just been recognized as novel mechanisms of inducing oncogenic PI3K signaling. Therefore, the class IA PI3K is the only one of most evidently implicated in cancer. The PI3K pathway is mostly mutated in more cancer patients compared with normal person, making it an eyecatching molecular target for analyses based on inhibitor molecule. In this article, we highlighted the signaling effects and regulation pathway of PI3K involved in the development and survival of tumor cells. The consequence and intricacy of PI3K pathway made it an essential beneficial target for cancer treatment.
