Application of homogeneously precipitated nanosized Fe-doped alumina powders to carbon nanotube growth. [PDF]

, 2010
Homogeneous precipitation of hydroxides was investigated as an alternative method to synthesize Fe-doped aluminum oxide (α-Al2−2xFe2xO3) particles over which carbon nanotubes (CNTs) were grown via a catalytic chemical vapor deposition (CCVD) method ...

Nanocrystalline apatites: From powders to biomaterials [PDF]

, 2009
Non-stoichiometric nanocrystalline apatite powders are used to elaborate highly-bioactive biomaterials. Their exceptional surface reactivity arises from a structured but rather unstable hydrated layer involving ions in nonapatitic chemical environments ...

Morphology and structure of YSZ powders: Comparison between xerogel and aerogel [PDF]

, 2009
Yttria-stabilized zirconia (YSZ) fine powders were prepared via sol–gel route in order to shape thermal barrier coatings (TBCs) from these powders. The main objective is to develop new undirectional coatings to allow best thermo-mechanical accommodations

Influence of pulse current during Spark Plasma Sintering evidenced on reactive alumina–hematite powders [PDF]

, 2011
Spark Plasma Sintering (SPS) is increasingly used. The temperature and current are not independent parameters, making it difficult to separate the current intrinsic role from Joule heating.

Hemostatic Comparison of a Polysaccharide Powder and a Gelatin Powder [PDF]

Journal of Investigative Surgery, 2018
Purpose/Aim: Powdered hemostats have been widely adopted for their ease-of-use; however, their efficacy has been limited resulting in applications restricted to low-level bleeds. This study investigates the use of bovine-derived gelatin particles (BGP) as a standalone hemostatic powder and compare BGP to commercially available microporous ...

Morphology–Coordination Coupling of Fe–TCPP and g-C₃N₄ Nanotubes for Enhanced ROS Generation and Visible-Light Photocatalysis

Nanomaterials
Fe–porphyrin/g-C3N4 composites have emerged as promising visible-light photocatalysts, but their performance remains limited by inefficient charge separation and low reactive oxygen species (ROS) yield.
