TL;DR: In this article, self-assembled monolayers of a small bifunctional molecule (4-carboxythiophenol) have been formed on Al and Au surfaces.
Abstract: Self-assembled monolayers of a small bifunctional molecule (4-carboxythiophenol) have been formed on Al and Au surfaces. The nature of coordination of the molecules to the two metal surfaces is different, leading to different terminal functionality of the monolayer surface. This aspect has been favorably exploited to self-assemble Ag particles from a colloidal solution on the monolayer-covered Al surface which is thiol rich. The self-assembly of the Ag particles does not take place on the monolayer-covered Au surface with carboxylic acid surface functionality. The adsorption of the monolayer on Al and Au surfaces and Ag colloidal particles on the self-assembled monolayer has been followed using electron microscopy, quartz crystal microbalance, and X-ray photoemission measurements. The two-dimensional array of strongly bonded metal nanoparticles shows potential for application as metal-supported catalysts and sensors, generation of submicrometer electronic devices, high density data storage, etc.

TL;DR: For the first time an alkali stable endoglucanase from alkalothermophilic Thermomonospora sp.
Abstract: Use of cellulase for denimwashing is a standard eco-friendly technique to achieve desirable appearance and softness for cotton fabrics and denims. But enzymatic washing of denim till date involved acid cellulase (Tricho- derma reesei) and neutral cellulase (Humicola isolens) the use of which has a drawback of backstaining of the indigo dye on tothefabric.ThoughithasbeensuggestedthatpHisamajor factor in controlling backstaining there are no reports on use of cellulase under alkaline conditions for denim washing. In this study for the first time an alkali stable endoglucanase from alkalothermophilic Thermomonospora sp. (T-EG) has been used for denim biofinishing under alkaline conditions. T-EG is effective in removing hairiness with negligible weight loss and imparting softness to the fabric. Higher abrasive activity with lower backstaining was a preferred property for denim biofinishing exhibited by T-EG. The activities were comparable to acid and neutral cellulases that arebeingregularly used.Theenzymewasalsoeffective under non-buffering conditions which is an added advantage for use in textile industry. A probable mechanism of enzymatic finishing of cotton fabric has been represented based on the unique properties of T-EG. Biotechnol. Bioeng. 2007;96: 48-56. 2006 Wiley Periodicals, Inc.

TL;DR: In this paper, a grafted tris-(triphenylphosphine) ruthenium(II) complex [RuHCl(CO)(PPh3)3] has been characterized by XRD, FTIR, N2 adsorption measurements, XPS and tested as catalyst for hydrogenation of olefins.
Abstract: Hydrido chlorocarbonyl tris-(triphenylphosphine) ruthenium(II) complex [RuHCl(CO)(PPh3)3] has been immobilized inside the pores of amine functionalized MCM-41 and SBA-15 materials. These grafted complexes were characterized by XRD, FTIR, N2 adsorption measurements, XPS and tested as catalyst for the hydrogenation of olefins. Immobilization and pore size has marked effects on the catalytic activity in the hydrogenation of olefins and the complex immobilized on functionalized SBA-15 was found to be catalytically more active than the one immobilized on MCM-41.
