The entrapment of proteins using the sol-gel route provides a means to retain its native properties and artifi cially reproduce the molecular crowding and confi nement experienced by proteins in the cell allowing investigation of the physico-chemical and structural properties of biomolecules at the biotic/abiotic interface. The biomolecules are spatially separated and ‘caged’ in the gel structu...

A novel type of zwitterionic HILIC stationary phase was prepared by covalently bonding the l-azido lysine on silica gel via click chemistry. The key intermediate azido lysine was synthesized by transformation the amino group in l-Boc-lysine to corresponding azido group and subsequent removal of the N-protected group (Boc). Finally, the azido lysine was covalently bonded to silica beads by click...

Novel cyclodextrin (CD) chiral stationary phases (CD-CSPs) with well-defined structure have been successfully synthesized by immobilization of mono/di(10-undecenoyl)-perphenylaminocarbonyl β-CD on the 3-mercaptopropyl functionalized silica gel via thiol-ene click chemistry. The phenyl carbamate groups on the rims of CD extended the cavity of CD-CSPs, which facilitated the formation of inclusion...

The surface chemistry of self-assembled hydrogel fibres - their charge, hydrophobicity and ion-binding dynamics - is recognised to play an important role in determining how the gels develop as well as their suitability for different applications. However, to date there are no established methodologies for the study of this surface chemistry. Here, we demonstrate how solution-state NMR spectrosc...

Abstract A new synthesis strategy for the preparation of cellulose derivative-based chiral selectors and subsequent mild immobilization onto pre-functionalized silica gel are introduced, utilizing Cu(I)-catalyzed alkyne-azide Huisgen cycloaddition (“ click ”) chemistry. 3,5-dimethylphenyl carbamate derivative carrying propynyl groups was prepared by a combination carbonate aminolysis isocyanate...

Batteries, as one of most versatile electrochemical systems, have potential to shape transition from climate crisis scenario a carbon neutral and sustainable future. In particular, metal–air batteries gaining scientific industrial interest promising contenders ubiquitous lithium-ion batteries. The el...

Mesoporous α-Fe2O3 thin films with large area homogeneity demonstrate tremendous potential in multiple applications. In the present work, synthesis of morphology-controlled is realized polystyrene-block-poly(4-vinyl pyridine) (PS-b-P4VP) diblock copolymer assisted sol-gel chemistry. The solvent category (DMF and 1,4-dioxane) polymer-to-FeCl3 ratio used for solution preparation are systematicall...

The topography, chemical and structural properties of titania surfaces are an important aspect to study. size nanoparticles synthetized by sol–gel method can influence the responses biological environment, using appropriate heat treatments different contents polymorphs be formed. Protein adsorption a crucial step for responses, involving, particular,...

Aloe (Lilliaceae) has long been used as a remedy in many cultures. Aloe products, which include the latex, gel, and whole leaf, are used, among other reasons, as laxatives, in creams for skin ailments, and as a treatment for a wide range of diseases, respectively. The heterogeneous nature of Aloe products may contribute to the diverse biological and therapeutic activities that have been observe...

We investigate the effect of the thickness of the silicon nitride (SiN x ) diffusion barrier on the structural and photocatalytic efficiency of TiO2 films obtained with different processes. We show that the structural and photocatalytic efficiency of TiO2 films produced using soft chemistry (sol-gel) and physical methods (reactive sputtering) are affected differentially by the intercalating SiN...
