Self-assembled solution micelles prepared from polystyrene-b-poly(4-vinylpyridine) (PS-b-P4VP) and polystyrene-b-poly(2-vinylpyridine) (PS-b-P2VP), have been employed as templates to synthesize copper nanocatalysts which are regarded as an excellent catalyst system for 1D nanomaterial synthesis. We have demonstrated that uniform-sized nanoparticles with diameters ranging from 1 to 15 nm have be...

Moving to Opportunity (MTO) offered public housing residents the opportunity to move to low-poverty neighborhoods. Several years later, boys in the experimental group fared no better on measures of risk behavior than their control group counterparts, whereas girls in the experimental group engaged in lower-risk behavior than control group girls. The authors explore these differences by analyzin...

A thermosensitive nanocatalyst was prepared in the reaction of water-soluble iron(III) porphyrins and thermosensitive polymeric nanospheres with a core-shell structure; its catalytic activity in cyclohexene oxidation by iodosylbenzene was dependent markedly on reaction temperatures in aqueous solution.

A strategy for the electrochemical detection of DNA based on catalytic hairpin assembly combined with nanocatalyst label-based redox cycling reaction signal amplification. A superior detection limit of 0.3 aM toward DNA can be achieved.

A novel and efficient procedure to prepare highly oxidised aryltetralin lignans, such as isopodophyllotoxone and (-)-aristologone derivatives, by oxidation of podophyllotoxin and galbulin with methylrhenium trioxide (MTO) and novel MTO heterogeneous catalysts is reported. It is noteworthy that in the case of isopodophyllotoxone derivatives the functionalisation of the C-4 position of the C-ring...

a new recoverable molybdenum nanocatalyst was prepared by immobilization  of a schiff base ligand on the surface of silica coated magnetite nanoparticles (fe3o4@sio2) through condensation reaction between 3-aminopropyl triethoxysilane and 2-hydroxy1-naphthaldehyde and succeeding reaction with dioxomolybdenum(vi) acetylacetonate (moo2(acac)2). the synthesized catalyst was characterized by induct...

Formaldehyde (HCHO), generating from hydrogen transfer (HT) of reactant, is significant for autocatalysis initiation and deactivation in methanol-to-olefins (MTO), but hitherto, its evolution throughout the reaction has not been thoroughly revealed. Herein, by established colorimetric analysis method, HCHO MTO dimethyl ether (DME)-to-olefins (DTO) reactions over SAPO-34 was situ quantitatively ...

While precious metals are available to a very limited extent, there is an increasing demand to use them as catalyst. This is also true for palladium (Pd) catalysts and their sustainable recycling and production are required. Since Pd catalysts exist nowadays mostly under the form of nanoparticles, these particles need to be produced in an environment-friendly way. Biological synthesis of Pd nan...
