An unusual copper(II) coordination polymer {[Cu(tmtz)(H2O)4][Cu2(tmtz)2(sip)2]·4H2O}n (1) (tmtz = 1,4-bis(1,2,4-triazol-1-ylmethyl)-2,3,4,5-tetramethylbenzene, sip = 5-sulfoisophthalate) is synthesized by the hydrothermal reaction. X-Ray structural analysis shows that 1 is comprised of two distinct and crystallographically independent polymeric motifs polythreading together. The first motif of ...

A freestanding H2-evolution electrode consisting of a copolymer-embedded cobaloxime integrated into a multiwall carbon nanotube matrix by π-π interactions is reported. This electrode is straightforward to assemble and displays high activity towards hydrogen evolution in near-neutral pH solution under inert and aerobic conditions, with a cobalt-based turnover number (TON(Co)) of up to 420. An an...

The catalytic properties of bulky water-soluble salen complexes in the oxidation of isoeugenol (2-methoxy-4-(1-propenyl) phenol) have been investigated in aqueous ethanol solutions in order to obtain a mixture of polymeric compounds through dehydrogenative polymerization. The average molecular weight of dehydrogenated polymers (DHPs) was monitored by GPC and correlated to reaction conditions su...

Preventing enzyme deactivation while increasing their accessibility by adsorption in mesopores remains a key challenge the design of biocompatible supported enzymatic catalysts. Herein, it is expected that food-grade monomeric or polymeric glycopeptides containing organic phosphate groups (as casein phosphopeptide derivatives) enhances entrapment over one pot method wet precipitation calcium (C...

There is a widespread interest in developing methods to recover homogeneous catalysts, particularly chiral catalysts, from a reaction mixture. The impetus to recover and reuse homogeneous catalysts stems not only from an economic standpoint but also from the need to eliminate contamination of the transition metal catalyst in the product and in the waste streams. The challenge is to recover the ...

In a liquid-liquid interface bioreactor, fungal cells locate in a hydrophilic polyacrylonitrile microsphere layer on an aqueous-organic interface. In this article, effects of hydrophobicity of the interface on n-decane hydroxylation activity of Monilliera sp. NAP 00702 was examined. (-)-4-Decanol production was significantly enhanced to 132% by addition of polytetrafluoroethylene.

This paper argues that innovation can be best understood as an information process which is then concretized as a product that meets demand. Two very different firms, Canon Inc. and Apple Computer Inc., are used as case study illustrations. Innovation does not proceed through logical deduction, but rather is furthered by the use of metaphors and analogies. The bureaucratic and staid structures ...

The observation of Manchot? that sodium pentacyano-ammineferroate2 I absorbs oxygen has led Baudisch and his coworkers3 to study the catalytic action of this salt, as well as of its water analogue II, in the oxidation of pyrimidines and purines. The present authors have previously reported in this journal4 on the nature of the oxidation products obtained. In the present paper the problem is con...

In this study, eugenol-loaded mPEG-PCL nanoparticles were used to improve the anti-bacterial properties of eugenol in an attempt eliminate resistant bacteria. The copolymer was prepared by ring-opening polymerization [Formula: see text]-caprolactone monomer vicinity a dry mPEG and tin (II) octoate catalyst. Polymeric through nanoprecipitation procedure. particle size zeta potential mPEG-PCL/eug...
