  SILVER: WATER DISINFECTION AND TOXICITY

... SILVER HAS BEEN KNOWN TO HAVE ANTIBACTERIAL PROPERTIES SINCE ROMAN TIMES, HOWEVER, THE INCREASED USE OF NANOSILVER IN A RANGE OF (AS YET LARGELY) EXPERIMENTAL DRINKING-WATER TREATMENT SYSTEMS, ITS USE IN CONJUNCTION WITH CERAMIC FILTERS AND ITS PERCEIVED POTENTIAL TO BE A WATER DISINFECTANT THAT DOES NOT RESULT IN DISINFECTION BY-PRODUCTS (DBP) IN THE TREATED WATER HAVE RAISED THE PROFILE OF THIS CHEMICAL. ...

  METALLIC NANOPARTICLES FOR CONDUCTIVE INKS

... CONDUCTIVE INKS ARE MAINLY BASED ON METALLIC PARTICLES. AT THE MOMENT SILVER FLAKE INKS GOVERN THE MARKET BUT OTHER SOLUTIONS APPEAR CONSTANTLY. THESE INCLUDE MORE ECONOMICAL MATERIALS SUCH AS COPPER AND COPPER OXIDE FLAKES AND METALLIC NANOPARTICLES HAVING IMPROVED PERFORMANCE. NANO PARTICLE BASED INKS ALLOW NOVEL APPLICATIONS TO BE CREATED THROUGH NEW MATERIAL COMBINATION POSSIBILITIES. ...

  PREPARATIONS OF SUPPORT FILMS FOR TEM GRIDS

... IN GENERAL, 200-400 MESH (LINES/IN) GRIDS ARE USED IN TEM EXPERIMENTS. MOST EM GRIDS ARE MADE OF COPPER BECAUSE IT IS NON-FERRO MAGNETIC AND THUS MINIMALLY DISTORTS THE MAGNETIC FIELD OF THE OBJECTIVE LENS. THE COPPER MESH ALSO RAPIDLY REMOVES HEAT AWAY FROM THE SUPPORT FILM AND THUS PREVENTS THERMAL EXPANSION AND MOVEMENT OF THE SPECIMEN UNDER ELECTRON IRRADIATION. ...

  CARBON COATED SI-CU/GRAPHITE COMPOSITE AS ANODE MATERIAL FOR LITHIUM-ION BATTERIES

... THE CARBON-COATED SI-CU/GRAPHITE COMPOSITE WAS OBTAINED BY MECHANICAL MILLING OF MIXTURE OF SI-CU ALLOY AND GRAPHITE FOLLOWED BY PYROLYSIS REACTION OF COAL-TAR PITCH. XRD AND SEM RESULTS SHOWED CU5SI ALLOY WAS FORMED AFTER THE INTENSIVE BALL MILLING AND SIC PHASE APPEARED AFTER PYROLYSIS, COMPOSITE PARTICLES WERE ENCAPSULATED BY CARBON MATRIX AND THE SURFACE BECOME SMOOTH AND COMPACT. ...

  AMORPHOUS HYDROGENATED CARBON DOPED WITH COPPER AS ANTIFUNGAL PROTECTIVE COATING

... WE REPORT ON THE FUNGISTATIC PROPERTIES OF AMORPHOUS HYDROGENATED CARBON DOPED WITH COPPER. IT IS CLEARLY DEMONSTRATED THAT COPPER FORMS CLUSTERS WITH SIZES OF SOME NANOMETERS. THESE CLUSTERS ARE DISTRIBUTED HOMOGENEOUSLY OVER AN AMORPHOUS CARBON MATRIX. DOPED FILMS, IN CONTRAST WITH UNDOPED ONES, INHIBIT FUNGI GROWTH AT THE FILM’S SURFACE. ...
