Atypical Growing Pattern of Superficial Temporal Artery Pseudoaneurysm.

Superficial temporal artery pseudoaneurysm is rare and usually caused by trauma. Pseudoaneurysms have been reported to occur most frequently from 2 to 6 weeks after trauma and they range from 1 to 3 cm in diameter. The authors present a case of a patient with an atypical delayed rapid growing pseudoaneurysm, who had undergone neurosurgery after head trauma 20 years ago.

Facile synthesis of one-dimensional iron-oxide/carbon hybrid nanostructures as electrocatalysts for oxygen reduction reaction in alkaline media.

One-dimensional iron-oxide/carbon hybrid nano tubular structures were synthesized via anodic aluminium oxide (AAO) template method. Highly unform iron oxide nanoparticles and carbon structures were formed simultaneously on the wall surface of the AAO template from an iron-oleate precursor by solventless thermal decomposition method. The 1D iron-oxide/carbon nanostructures were obtained after removing the AAO template.

A chemically activated graphene-encapsulated LiFePO4 composite for high-performance lithium ion batteries.

A composite of modified graphene and LiFePO4 has been developed to improve the speed of charging-discharging and the cycling stability of lithium ion batteries using LiFePO4 as a cathode material. Chemically activated graphene (CA-graphene) has been successfully synthesized via activation by KOH. The as-prepared CA-graphene was mixed with LiFePO4 to prepare the composite.
