The friction force for aircraft landing is mainly provided by the texture of runway surfaces. mechanism underlying generation energy dissipation tire rubber materials during random excitation induced asperities. However, surface deteriorated cyclic loading and environmental effects service life a runway, leading to loss braking extension distance. Additionally, when an lands on wet at high velo...

Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) and its agnostic antibodies, which are being evaluated clinically as anticancer therapies, selectively kill cancer cells through the death receptors DR4 and DR5. However, their therapeutic potential is limited by occurring resistance in tumor cells. Here, we compared the apoptotic response of a panel of six human breast cancer cell...

We present a systematic in situ study of the effect of postdeposition low-energy s200 eVd ion bombardment on resistance and surface topography of ultrathin iron s,50 Åd and copper s,130 Åd films. The ion-beam-induced nanosmoothening occurs while material is being removed and gives rise to an initial decrease in resistance followed by a steady increase as the film is subsequently uniformly erode...

The grafting of polymers onto a carbon black surface based on the trapping of polymer radicals by polycondensed aromatic rings of the surface was investigated. It was found that polymer radicals formed by the thermal decomposition of azo-polymer, peroxy-polymer and 2,2,6,6-tetramethylpiperidinyl-1-oxy-terminated polymer are successfully captured by a carbon black surface to give the correspondi...

TiO2 nano-particles were used in electroless plating bath to obtain Ni/P/nano-composite coatings. The coatings were heat treated at 200, 400, 600 and 700 oC and their chemical and physical properties were investigated and it was found that 400 oC was the optimum temperature for the heat treatment of the coatings. The micro-hardness test of coatings showed that t...

In this study latent heat flux (λE) measurements made at 65 boreal and arctic eddy-covariance (EC) sites were analyses by using the Penman-Monteith equation. Sites were stratified into nine different ecosystem types: harvested and burnt forest areas, pine forests, spruce or fir forests, Douglas-fir forests, broadleaf deciduous forests, larch forests, wetlands, tundra and natural grasslands. The...

To better understand thermal transport at nanoscale point contacts such as the tip-sample contact of a scanning probe microscope and at the contact between a nanotube and a planar surface, we have used a nonequilibrium molecular dynamics MD method to calculate the temperature distribution and thermal resistance of a nanometer scale constriction formed between two planar silicon substrates of di...

One of the most complex topics within bacterial anatomy and physiology is that of exopolysaccharides. These molecules have various structures and functions and also provide different types of advantages to their producing microorganisms, including surface variability, resistance to innate and acquired immunity mechanisms, the ability to adhere to different surface and cell types and resistance ...
