The synthesis of bulk imprinted silica using colloidal gold as a functional template is demonstrated. The imprinting approach relies on the isolation of colloidal gold in gold@silica nanoparticles synthesized via a 3-aminopropyltrimethoxysilane (APS) route. Gold@silica nanoparticles are then condensed within a silica framework for the synthesis of a composite gold-silica material containing ~30...

The use of polymeric supports in solid-phase peptide synthesis has allowed for the facile, rapid synthesis of short peptides in a one bead/one sequence manner. This approach allows for screening peptide libraries for binding and catalytic activities. Once hits are found, the sequence of the active protein can be determined via mass spectrometry. However, problems arise when trying to create lar...

Polyamide 12 (PA 12) has been nanostructured by reactive blending with 20 wt% of a symmetric anhydride end-capped polysty-rene-b-polyisoprene (PS-b-PIP-anh) The liposome-like nanovesicles which are originally formed in the polyamide matrix (PA 12) are converted into cucumber-like coreshell nanoobjects upon increasing the volume fraction of PS by addi-j tion of homo PS of a molecular weight lowe...

Nanomaterials including nanoparticles, nanowires and nanotubes play an important role in heterogeneous catalysis. Thanks to the rapid improvement of the electron microscopic techniques and with the advent of aberration corrected electron microscopy as well as theoretical methodologies, the potential effects induced by nanocatalysts are better understood than before by unravelling their atomic s...

Singapore Grouper Iridovirus (SGIV) is a member of nucleo cytoplasmic large DNA viruses (NCLDV). This paper reports the functional analysis of ORF75R, a major structural protein of SGIV. Immuno fluorescence studies showed that the protein was accumulated in the viral assembly site. Immunogold-labelling indicated that it was localized between the viral capsid shell and DNA core. Knockdown of ORF...

The core-shell hybrid structure is the simplest motif of two-component systems which consists of an inner core coated by an outer shell. Core-shell composite materials are attractive for their biomedical, electronic and catalytic applications in which interface between core and shell is critical for various functionalities. However, it is still challenging to study the exact role that interface...

Photoelectrodes made of submicrometer-sized aggregates of ZnO nanocrystallites coated with TiO2 layer by atomic layer deposition with different annealing temperatures were investigated for dye-sensitized solar cells. Although the annealing at 350 C is commonly used for the ZnO aggregates in order to preserve the desired large surface area and mesoporous structure, the presence of ALD-TiO2 layer...

In this paper, Fe3 O4 @SiO2 core/shell magnetic nanostructure has been synthesized and modified by N-(2-aminoethyl)-3-aminopropyltrimethoxysilane (AEAPTMS). Fe3 O4 @SiO2 was used as a novel adsorbent for separation of hexachloroplatinic acid. X-ray diffraction (XRD), scanning electron microscopy (SEM), and FT-IR technique were used to characterize morphologies and surface texturing of these ads...

the effects of temperature, time and the strategy of prepolymerization were studied on the morphology of polypropylene particles. propylene polymerization was carried out in slurry phase using 4th generation of ziegler-natta catalyst, cyclohexylmethyl dimethoxysilane as external electron donor, and triethyl aluminum as co-catalyst. prepolymerizations were carried out based on two strategies: is...

The screening of a 2p core-hole in Na clusters is investigated using density functional theory (DFT) applied to an extended jellium model with an all-electron atom in the center. The study is related to recent experiments at the free-electron laser at DESY in which photoelectron spectra from mass-selected, core-shell-ionized metal clusters have been recorded. Relaxed and unrelaxed binding energ...
