Cell surface GPI-anchoring of CD45 isoforms

Molecular Biology Reports, 1998
We have designed a new cell surface expression plasmid to study the structural and membrane-topological requirements for functioning of different isoforms of CD45, a leucocyte specific member of the protein tyrosine phosphatase (PTPase) family of proteins. Use of this vector in cell transfection experiments enabled us to produce multiple CD45 isoforms (

The Impact of Colloidal Surface-Anchoring on the Smectic A Phase

Langmuir, 2017
Liquid-crystalline phases are known for their unique properties, i.e., the combination of fluidity and long-range orientational and/or positional order. The presence of a colloidal particle gives rise to perturbations of this order locally. These perturbations are the origin of intercolloidal forces driving the colloidal self-assembly in a directed ...

Magnetite Nanoparticles Anchored to Crystalline Silicon Surfaces

Chemistry of Materials, 2005
Magnetite nanoparticles of 5 nm mean diameter, coated with 10-undecynoic acid, have been anchored to crystalline Si(100) surfaces via the hydrosilylation reaction at 180 °C. The iron content in the sample (0.54 ± 0.05 ¼g/cm2) has been determined by atomic absorption analysis. The sample has been further characterized by X-ray photoelectron spectroscopy,

Index grating surface anchoring

SPIE Proceedings, 2005
A simple model describing location of Raman-Nath index grating photoexcited in a planar cell with photoconductive orienting layers is proposed. We believe that index grating vector is parallel to cell boundaries. One of the most important features resulting from this model is that the index grating spacing equals to projection of the exciting optical ...

On the Anchoring of Nematics on Silicon Surfaces

Molecular Crystals and Liquid Crystals Incorporating Nonlinear Optics, 1990
Abstract The study of anchoring on silicon surfaces with [001], [111] and [110] orientation shows that a nematic liquid crystal orients itself parallel to the two-fold axes of the surfaces. For [001] orientation, this leads to a bistable anchoring. For [111] orientation, the expected tristable anchoring is not observed, and only one anchoring direction

Efficient and Stable Chemical Passivation on Perovskite Surface via Bidentate Anchoring

Advanced Energy Materials, 2019
Chemical passivation is an effective approach to suppress the grain surface dominated charge recombination in perovskite solar cells (PSCs). However, the passivation effect is usually labile on perovskite crystal surface since most passivating agents are

A General Atomic Surface Modification Strategy for Improving Anchoring and Electrocatalysis Behavior of Ti3C2T2 MXene in Lithium-Sulfur Batteries.

ACS Nano, 2019
Multiple negative factors, including the poor electronic conductivity of sulfur, dissolution and shuttling of lithium polysulfides (Li2Sn), and sluggish decomposition of solid Li2S, seriously hinder practical applications of lithium-sulfur (Li-S ...

Surface anchoring of rodlike molecules on corrugated substrates

The Journal of Chemical Physics, 2006
We studied the mechanism of surface anchoring of rodlike molecules on substrates with the surfaces corrugated at molecular scale by molecular-dynamics simulation. We constructed a model for substrates that can have anisotoropic topographical patterns such as corrugation. The structural and thermodynamic properties of rodlike molecules on the corrugated

Surface‐Anchored MOF‐Based Photonic Antennae

ChemPhysChem, 2012
AbstractThe loading of a metal‐organic framework (MOF), [Cu3(btc)2xH2O] HKUST‐1, with europium β‐diketonate complexes is studied with the goal to using the porous molecular framework as a photonic antenna. Whereas loading of HKUST‐1 powder particles produced via the conventional solvothermal synthesis method was strongly hindered, for HKUST‐1 SURMOFs ...
