The objective of this investigation is to fabricate a natural material based composite and study its tensile strength. The water hyacinth is a plant which is considered as an unwanted wild growth which is detrimental to the water bodies. It affects the oxygen and nutrients content of the fresh and sewage water and als…
Patterned highly absorbing gold black film has been selectively deposited on the active surfaces of a vanadium-oxide-based infrared bolometer array. Patterning by metal lift-off relies on protection of the fragile gold black with an evaporated oxide, which preserves gold black’s near unity absorption. This patterned g…
Since the last ten years, research happenings in the field of nanomaterials have been increased dramatically. Materials scientists and researchers have realized that the mechanical properties of materials can be altered at the fundamental level, i.e. at the atomic-scale. Carbon nanotubes have been well recognized as n…
In this paper, we describe the design and construction of a Multi Array Faraday Cup for both beam profiling and current measurements in a Penning ion source. This diagnostic system includes an array configured from multiple cups electrically isolated from each other to collect charged particles incident on the respect…
Purpose: The method of one-pot synthesis of Ag@Fe 3 O 4 nanoparticles consisting of a spherical core of magnetite and silver islet shell has been developed. Formation of Ag@Fe 3 O 4 composite structures such as "core-shell" will allow combining magnetic controllability of the magnetite core with bactericidal and bacte…
Efficient modification of energy band gap to absorb visible light in TiO 2 semiconductor nanocomposites is challenging. The effect of the varying CdS thickness (50-100 nm) on the structural and optical properties of TiO 2 /CdS nanocomposite films (NCF) grown by electron beam deposition is reported. The surface morphol…
Bio-inspired 3D hierarchical nanowebs are fabricated using silicon micropillars, carbon nanotubes (CNT), and manganese oxide. The Si pillars act as artificial branches for growing CNTs and the secondary metal coating strengthens the structures. The simple but effective structure provides both chemical and mechanical s…

An Experimental investigation was carried out to determine performance, emissions and combustion characteristics of diesel engine using nanoaluminum oxide (n-Al2O3) blended diesel fuel. The n-Al2O3 of size 40 nm was blended into diesel fuel. The different dosing levels studied were 250mg, 500mg, 750mg, and 1000mg. Eac…
In this present work the effect of reinforcement of hybrid fillers such as nanoclay and carbon black in natural rubber were studied. Sodium bentonite clay was organically modified with octadecyl amine using cation exchange reaction and characterized by FTIR, XRD and SEM. The organomodified clay with 5 phr loading and…
The operational characteristics of capacitor-type detectors based on HPHT and CVD diamond have been investigated using perpendicular and parallel injection of carrier domain regimes. Simulations of the drift-diffusion current transients have been implemented by using dynamic models based on Shockley-Ramo's theorem, un…
Cross-linking plays an important role in tissue engineering, which involves the alternative of cross-linker and the way of components interaction. We compared two proanthocyanidin (PA) cross-linked recombinant human collagen-peptide - chitosan scaffolds: immerse cross-linking (I-CLS) and premix cross-linking (P-CLS).…
Direct growth of vertically aligned carbon nanotube (CNT) arrays on substrates requires the deposition of an aluminum oxide buffer (AOB) layer to prevent the diffusion and coalescence of catalyst nanoparticles. Although AOB layers can be readily created on flat substrates using a variety of physical and chemical metho…
Bio-composites are taking over the polymer based composites due to their multi fold advantages. In this work, the natural fibre (jute-hemp) hybrid composite was prepared by traditional hand-lay-up method. The hardness, tensile and flexural properties of the composite specimen was evaluated in order to study the effect…
Controlling cell behavior has generated immense attention in the fields of tissue engineering and regenerative medicine. Particular emphasis has been given to the creation of 3D biomimetic cellular microenvironments that replicate the complex nature of the extracellular matrix (ECM). A key factor that has not been rig…
The mobility of a colloidal particle in a crowded and confined environment may be severely reduced by its interactions with other mobile colloidal particles and the fixed obstacles through which it diffuses. The latter may be modelled as an array of obstacles with random fixed positions. In this contribution, we repor…
Stilbene (St) derivatives have been investigated for many years because of their interesting photochemical reactions such as cis-trans isomerization in the excited states and charged states and their relation to poly(p-phenylenevinylene)s. To clarify their charged state properties, structural information is indispensa…
Anhydrous alkali metal hydroxide (KOH, NaOH, and LiOH)-activated macrocyclic ligand complexing metal cations, i.e., coronands 12C4, 15C5, 18C6, DCH24C8, and cryptand C222, were selected for initiation of β-butyrolactone (β-BL) and ε-caprolactone (ε-CL) polymerization. It was found that β-BL polymerizes in the presence…
In this paper, the electrochemical deposition was used to form calcium phosphate/chitosan (Ca-P/chitosan) membranes on the surface of AZ91D magnesium alloy coated with a microarc oxidization (MAO) membrane. The surface appearance, chemical compositions, and crystalline structures of the Ca-P/chitosan membranes were de…
We systematically investigated the recovery ability of some silylation materials for a plasma-damaged porous silica low- k material. In order to evaluate recovery ability, the permittivity and leakage current were measured. The recovery ability is listed in ascending order as ethoxy group, disilazane group, and dimeth…
