Nano Ultraviolet Finishing of Textiles Using Inorganic UV- Blockers–The Sustainable Approach of Producing Protective Clothing for Better Tomorrow
Abstract: The diminution of the ozone stratum,due to global warming, is likely to intensify existing health effects caused by exposure to ultraviolet (UV) radiations, as stratospheric ozone is a predominantly effective UV radiation absorber. As the ozone layer becomes thinner, the protective filter provided by the atmosphere is gradually abridged. Subsequently, human beings and the environment are exposed to higher UV radiation levels, particularly higher UV-B levels, which have the greatest …

Photon activated tunneling in ABO3 type Multiferroic domain wall
Abstract: We present photon assisted tunneling in multiferroics of type ABO3. It is seen that the interactions of photons with this analytic molecule accelerate the electron transmissions. It is clarified that the existence of ferromagnetic, ferroelectric, and piezoelectric in multiferroic materials are consequence of magnetic anisotropy, dipole segregation and strain. The effect of photon is therefore, to disassemble existing electronic states or assemblesto form new electronic states by enhancing its transmission …

Advanced Techniques for Delamination Toughening in Carbon Fibre Reinforced Composites
Abstract: Carbon fibre reinforced composites are widely used in various industries due to their excellent strengthto-weight ratio and stiffness properties. However, one of the major issues in these composites is delamination, which occurs due to the weak interlaminar bonding between the layers of fibers and matrix. Delamination leads to a reduction in the load-carrying capacity and structural integrity of the composite. To address this issue, several advanced techniques for delamination toughening …

Plastics Compressive Strength Testing
Abstract: Compression test is a mechanical test that determines how much compressive force a material to resist before cracking. A gradually applied load compresses the test item, which is commonly in the shape of a square, pyramid, or cylinder, between the platens of a compression-testing machine. Many ductile metals, such as mild steel, have extremely high compression strength, yet measuring them is challenging. Whenever a load is given to a ductile …
