Two kinds of RDX samples, with broad and narrow particle size distribution, have been fabricated by wet riddling and solvent/non-solvent methods, respectively. By controlling the technical condition, the RDX powders with different particle sizes were obta... see more

The mechanical strengths of nano-scale individual crystal or nanopolycrystalline metals, and other dimensionally-related materials are increased by an order of magnitude or more as compared to those values measured at conventional crystal or polycrystal g... see more

On 30 patients with endotracheal tubes and mechanical ventilation, bacteriological culture has been done using a simple, safe and quite reliable technique. During this study we found that gram negative bacteria especially Pseudomonas aeruginosa were the m... see more

Boron-potassium nitrate (B-KNO3)-based compositions have been used as an effective ignitersystem for solid rocket propellants. A systematic study was undertaken to generate exhaustivedata on B-KNO3 (25:65)-based ignition systems with cellulosic binders, v... see more

Introduction. A promising direction in the evaluation of the structure of materials is the use of fractal formalism. Its use  makes  it  possible  to  predict  some  properties  of  materials  on  the... see more

The strain rate sensitivity (SRS) and dislocation activation volume are two inter-related material properties for understanding thermally-activated plastic deformation, such as creep. For face-centered-cubic metals, SRS normally increases with decreasing ... see more

The HEA-CoCrFeNiAl0.3 thin film in this study has been successfully developed by radio frequency (RF) magnetron sputtering to meet the increasing demand in engineering applications. Its microstructure and surface profile were investigated accordingly. The... see more

Cymbal is a class-V flextensional transducer that consists of thickness poled ceramic disc sandwiched between the two metal end caps which acts as a mechanical transformer. Cymbal transducers were fabricated using piezoceramic discs of compositions Pb0.98... see more

This paper reports the evaluation of four different energetic plasticisers, viz., glycidyl azidepolymer (GAP, MW = 390), 1,5-diazido-3-nitrazapentane (DANPE), ethylene-glycol-bis-azido-acetate (EGBAA) and N-n-butyl-N-(2 nitroxyethyl) nitramine (n-Bu-NENA)... see more
