a particles emitted from an Am radioactive source at energies of 5.4 MeV generate bursts of about ten electrons when passing through an aluminized Mylar foil. Besides the typical surface barrier electrons, the energy spectra of the secondary electrons clearly reveal two additional peaks. One at 66 eV is ascribed to aluminum LVV Auger electrons and another at 10.5 eV is attributed to the decay o...

Studies have been conducted to find Materials with microstructures which Minimize the formation of blisters. A promising class of materials appears to be sintered metal powder with small average grain sizes and low atomic number Z. Studies of the surface erosion of sintered aluminum powder (SAP 895) and of aluminum held at AOO'C due to blistering by 100 keV helium ions have been conducted and t...

This paper describes a microparticle delivery device that generates a plasma jet through laser ablation of a thin metal foil and uses the jet to accomplish particle delivery into soft living targets for transferring biological agents. Pure gold microparticles of 1 µm size were coated with a plasmid DNA, pIG121Hm, and were deposited as a thin layer on one surface of an aluminum foil. The laser (...

suckers are strong sinks of water and nutrients, thus they have intensive competition with plant vegetative parts like scion of budded seedlings. this is an enormous problem of citrus nurseries in north of iran. as far as vast input and time is spending on control of these unwanted suckers. this research, that carried out in design, compares 10 different sucker control methods in three citrus r...

A high-throughput process for nanotexturing of hard and soft surfaces based on the roll-to-roll anodization and etching of low-cost aluminum foils is presented. The process enables the precise control of surface topography, feature size, and shape over large areas thereby presenting a highly versatile platform for fabricating substrates with user-defined, functional performance. Specifically, t...

Abstract Aluminum is an attractive candidate for replacing graphite anodes in lithium‐ion batteries because of its high specific capacity and the potential direct use as foil. However, achieving reversible reaction aluminum challenging due to volume changes, SEI formation, sluggish ion transport. Although prior work has investigated electrochemical transformation behavior aluminum, effects key ...

We present the first case documented in the literature of perforation of bowel due to drug tablet with package ingestion. A diagnosis of perforation was made by CT imaging revealing a staple-like foreign body with air-content in the distal ileum. Adjacent abscess with free air formation also noted. This is an unusual case of small intestine perforation due to a foreign body that was preoperativ...

Liquid food packages consist of various polymers films, which are bonded together with Aluminum foil (Al-foil) using adhesion or by direct heat. The main aim this research was to define important material properties such as fracture toughness and some FE-simulation model parameters damage initiation, evolution, the between Al-foil low-density polyethylene (LDPE) film. This investigation is base...

The present study aims at developing A356/Al2O3(np) nano-composite with a novel and cost effective method for attaining homogeneous dispersion of Al2O3 nanoparticles in the Al matrix. In the current research, Al micro powders distributed on aluminum foil and then Al2O3 nanoparticles ultra-sounded in ethanol and sprayed on Al substrate. Subsequently, the sandwich foil was added to molten A356 du...
