  • The Commission emphasizes that this definition is based solely upon the dimensions of particles and does not constitute any indication of hazards or risks which may (or may not) be presented by a particular nanomaterial. (dguv.de)
  • 6.2) of particles without substantially changing MMADs (1m:1.02 0.99 0.98). (cdc.gov)
  • When launched at this slightly slower rate, the particles created a more porous structure, which is ideal for biomedical applications, such as artificial joints for the knee or hip, and cranial/facial implants. (plastemart.com)
  • Several group VIII transition metal (Fe, Co, and Ni) nitrides are studied as core materials, with Ir/Fe 4 N core-shell particles showing enhancement in both OER activity and stability. (osti.gov)
  • Properties and Selection: Stainless Steels, Tool Materials and Species-Purpose Metals Titanium and Titanium Alloys). (chula.ac.th)
  • Materials scientist Samuel Sanchez , of the Leibniz Institute for Solid State and Materials Research, in Dresden, Germany, has built magnetically steered Janus particles from platinum and cobalt, but they relied on toxic hydrogen peroxide as their medium and source of fuel. (ieee.org)
  • They found calcium -based particles, such as calcite and aragonite, minerals often used in construction materials, abrasives, soil treatment, pigments, and as a pharmaceutical additive. (medicalnewstoday.com)
  • The things in nano technology that might pose a risk to us or to the environment are related to the fact that we need to make sure that we handle these new particles and materials in a safe way. (lu.se)
  • Secondly, the lifetimes become shorter and shorter of the superheavy nuclei which can be produced with a given selection of stable ion beams (calcium, titanium, chromium, iron etc.) and actinide target materials. (lu.se)
  • A new kind of laser uses tiny moving particles to produce beams of light. (newscientist.com)
  • Scientists are discovering that inhaled toxic particles may be able to reach and possibly damage the brain. (medicalnewstoday.com)
  • A new study from researchers at the University of Birmingham in the U.K. and Chinese research institutions found that such pollution-borne toxic particles can also reach the brain. (medicalnewstoday.com)
  • Some particles the researchers found were typical of air pollution. (medicalnewstoday.com)
  • The researchers had to carefully calibrate titanium alloy's ideal speed. (plastemart.com)
  • Once the particles collided and bonded together, the researchers heated the metal so the components would diffuse into each other and settle like a homogeneous material. (plastemart.com)
  • acid, as well as titanium compounds. (cdc.gov)
  • Some enter your body if you breathe air that is of the titanium compounds may settle out to soil or contaminated with it. (cdc.gov)
  • Some of the titanium compounds may settle out to soil or water. (cdc.gov)
  • For example, 3D printing of diamond particles (as the hardest material with super hard crystals) needs extremely high temperature, pressure, and laser current. (hindawi.com)
  • Whilst impaction and interception are factors that are more dominant for micro-sized particles, nanosized particle depositions are more driven by diffusion (in particular at low air speed, such as in the alveoli) and surface charge. (lu.se)
  • Finely dispersed particles form explosive mixtures in air. (ilo.org)
  • Typically in cold spray printing, a particle would accelerate in the sweet spot between its critical velocity - the speed at which it can form a dense solid - and its erosion velocity, when it crumbles too much to bond to anything. (plastemart.com)
  • These in situ results were compared with those using conventional sodium hypochlorite tissue digestion and particle filtration. (usgs.gov)
  • The particle dispersion in a cured, dry, or solid medium depends on the dispersion efficiency in the wet state, which depends on the effectiveness of the deagglomeration process. (usp.br)
  • Whether this causes or contributes to debilitating disease over a normal lifespan depends on the type and concentration of the particles. (usgs.gov)
  • Since it is not possible with current 3D printers, designing special printers or mixing diamond particles with other powders is inevitable. (hindawi.com)
