A study on the Low Stress Mechanical properties of spun silk sarees woven on Handloom

open access: yesTextile & Leather Review, 2022
The silk handloom industry consumes two-thirds of the raw silk produced domestically in India. It was envisaged to develop a handloom silk saree using spun silk as warp and or weft and study the fabric characteristics in terms of low-stress mechanical ...

Everything is illuminated [PDF]

open access: yesGeom. Topol. 20 (2016) 1737-1762, 2014
We study geometrical properties of translation surfaces: the finite blocking property, bounded blocking property, and illumination properties. These are elementary properties which can be fruitfully studied using the dynamical behavior of the SL(2,R)-action on the moduli space of translation surfaces.

Waveguiding properties of surface states in photonic crystals [PDF]

open access: yes, 2005
We propose and analyze novel surface-state-based waveguides in bandgap photonic crystals. We discuss surface mode band structure, field localization and effect of imperfections on the waveguiding properties of the surface modes. We demonstrate that surface-state-based waveguides can be used to achieve directional emission out of the waveguide.

Synthesis, Characterization, and Biological Evaluation of Nanostructured Hydroxyapatite with Different Dimensions

open access: yesNanomaterials, 2017
Nanosized hydroxyapatite (HA) is a promising candidate for a substitute for apatite in bone in biomedical applications. Furthermore, due to its excellent bone bioactivity, nanosized strontium-substituted HA (SrHA) has aroused intensive interest. However,

Coagulation Behavior of Antimony Oxyanions in Water: Influence of pH, Inorganic and Organic Matter on the Physicochemical Characteristics of Iron Precipitates

open access: yesMolecules, 2022
The presence of inorganic and organic substances may alter the physicochemical properties of iron (Fe) salt precipitates, thereby stabilizing the antimony (Sb) oxyanions in potable water during the chemical treatment process. Therefore, the present study

Influence of Surface Properties of Nanostructured Ceria-Based Catalysts on Their Stability Performance

open access: yesNanomaterials, 2022
As the poor cycling stability of CeO2 catalysts has become the major obstacle for applications of diesel particulate filters (DPF), it is necessary to investigate how to reduce their structural and compositional changes during soot oxidation.
