In this paper, the wet modification method is compared with grafting to modify nano-barium sulfate. The effects of method, time, modifier dosage, temperature, and other factors on degree activation modified sulfate are investigated solve agglomeration problems make it a suitable process for industrial production. Thermogravimetric analysis, infrared spectroscopy, scanning electron microscopy us...

This paper presents the fabrication of rough super-hydrophobic surfaces, dynamic measurements of sliding angles of water droplets, and a modeling approach to estimate bounds on contact angle hysteresis—the major dissipative mechanism in droplet based microfluidic systems. We investigate the dependence of hysteresis on texture parameters, evaluate the current model, propose a modification, and s...

In this paper we presented a method for the preparation and characterization of glutathione-coated near infrared (NIR) QDs (CdSeTe/CdS) with core-shell structure. The preparation method is based on surface modification of hydrophobic core/shell CdSeTe/CdS by glutathione, which makes the QDs water-soluble and stabilized in aqueous solution. The particles were further added to cultivation solutio...

We propose a simple modification to the hydrophobic-polar (HP) protein model, by introducing a new type of monomer, “0”, with intermediate hydrophobicity of some amino acids between H and P. With the replica-exchange Wang–Landau sampling method, we investigate some widely studied HP sequences as well as their H0P counterparts and observe that the H0P sequences exhibit dramatically reduced groun...

Nanoporous Solid-Liquid core waveguides were prepared by UV induced surface modification of hydrophobic nanoporous polymers. With this method, the index contrast (deltan = 0.20) is a result of selective water infiltration. The waveguide core is defined by UV light, rendering the exposed part of a nanoporous polymer block hydrophilic. A propagation loss of 0.62 dB/mm and a bend loss of 0.81 dB/9...

An overview is given on the developments of using porphyrin-modified DNA for the construction of functional assemblies. Strategies for the synthesis and characterisation are presented alongside selected applications where the porphyrin modification has proven to be particularly useful, but also revealed its limitations. We also discuss implications on property and behaviour of the porphyrin-DNA...

As a way to control the surface properties of nanowires and nanotubes, we present a method for growing polymer from the surface of silicon/silica core/shell nanowires. After modification of nanowire surfaces with polymer initiators, Atom Transfer Radical Polymerization (ATRP) was used to grow methacrylate polymer chains from the surface. The resulting structures were characterized by SEM, TEM, ...
