High electrically conductive composites of Polyamide 11 filled with silver nanowires: Nanocomposites processing, mechanical and electrical analysis [PDF]

, 2013
Highly conductive composites of silver nanowires and semicrystalline polyamide 11 for different content were prepared. A newmethod was developed to introduce nanowires: a combination of solventway and an extrusion process.

Structure evolution and mechanical behavior of poly(ethylene terephthalate) fibers drawn at different number of drawing stages [PDF]

Chemical Industry and Chemical Engineering Quarterly, 2012
In this work, the structure, mechanical and thermal properties of PET fiber obtained by hot multi-stage drawing have been investigated in terms of their dependence on the number of drawing steps at an equivalent total draw ratio. Differential scanning

Effects of Degree of Particle Melt and Crystallinity in SLS Nylon-12 Parts [PDF]

, 2008
Differential Scanning Calorimetry (DSC) traces for SLS Nylon-12 parts display two distinct melt peaks, which have been related to the presence of both melted and crystallised regions, and un-melted particle cores within the part.

Crystalline Nephropathies [PDF]

Archives of Pathology & Laboratory Medicine, 2012
Context.—The kidney is a favored site for crystal deposition because of the high concentration of ions and molecules reached at the level of the renal tubules in the course of filtration. This review focuses on crystalline nephropathies in 4 broad categories: (1) dysproteinemia- associated, (2) drug-induced, (3) calcium-containing, and (4) metabolic or

Crystalline bacterial catalase [PDF]

Biochemical Journal, 1947
It is now fifty-four years since Gottstein1 discovered that some bacteria are able to decompose hydrogen peroxide with evolution of gaseous oxygen, an activity he attributed to their possessing an intracellular enzyme which later came to be called ‘catalase’.

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...
