Chauhan, Sunil Thakur Abstract: In this paper the friction and wear characteristics of vinylester and vinylester composites have been investigated under dry sliding conditions for different applied normal load, sliding speed and sliding distance.
View abstract View article PDF Proteins are insulating molecular solids, yet even those containing easily reduced or oxidized centers can have single-molecule electronic conductances that are too large to account for with conventional transport theories.
In order to overcome the limitations of the STM, the time- and voltage-dependence of the conductance were further explored using a fixed-gap 5 nm tunneling junction device that was small enough to trap a single protein molecule at any one time.
Nanoamp two-level signals indicate the specific capture of a single molecule in an electrode gap functionalized with the ligand. This offers a new approach to label-free electronic detection of single protein molecules.
Electronic structure calculations yield a distribution of energy level spacings that is consistent with a recently proposed quantum-critical state for proteins, in which small fluctuations can drive transitions between localized and band-like electronic states.
Solvent-free optical recording of structural colours on pre-imprinted photocrosslinkable nanostructures Optical digital information storage media, despite their ever-increasing storage capacity and data transfer rate, are vulnerable to the potential risk of turning inaccessible.
For this reason, long-term eye-readable full-colour optical archival storage is in high demand for preserving valuable information from cultural, intellectual, and scholarly resources. However, the concurrent requirements in recording colours inexpensively and precisely, and preserving colours for the very long term for at least yearshave not yet been met by existing storage techniques.
Structural colours hold the promise to overcome such challenges.A polyurethane coating is also applied with varied thickness to give better wear rate and surface coating properties. A fuzzy logic approach is adopted to invent the optimal wear rate and surface coating using coating thickness and fiber content properties.
To do so, a pin on disc apparatus is designed and fabricated. Experiments are carried out at sliding speed 1, 2, 3 m/s, normal load 15 N and relative humidity 70%. In general, friction coefficient and wear rate increase with the increase in sliding speed for all the tested materials.
