Graphene/Sulfur/Carbon Nanocomposite for High Performance Lithium-Sulfur Batteries
Here, we report a two-step synthesis of graphene/sulfur/carbon ternary composite with a multilayer structure. In this composite, ultrathin S layers are uniformly deposited on graphene nanosheets and covered by a thin layer of amorphous carbon derived from β-cyclodextrin on the surface. Such a unique microstructure, not only improves the electrical conductivity of sulfur, but also effectively in...
متن کاملFreeze-dried B.C.G.
Freeze-dried B.C.G. of British manufacture became available for experimental work in 1955. The main reason for introducing it was the need for a vaccine which would retain its potency under conditions of prolonged storage. On reconstitution for injection the vaccine should produce a uniform suspension with minimal clumping, resulting in a uniform viable bacterial count. These properties mean th...
متن کاملFreeze-dried specimens for gross anatomy teaching.
As more and more emphasis is placed on the use of prosected specimens to support teaching and learning of gross anatomy, consideration must be given to developing new methods to preserve human cadaveric material, and in ways which will resist the wear and tear to which they are necessarily subjected. Taxidermists have developed techniques for freeze-drying whole small animals as a method of lon...
متن کاملFreeze-Dried Somatic Cells Direct Embryonic Development after Nuclear Transfer
The natural capacity of simple organisms to survive in a dehydrated state has long been exploited by man, with lyophylization the method of choice for the long term storage of bacterial and yeast cells. More recently, attempts have been made to apply this procedure to the long term storage of blood cells. However, despite significant progress, practical application in a clinical setting is stil...
متن کاملFreeze-dried blood cells: therapeutic advance or laboratory curiosity?
Platelets are anucleate, cellular elements present in circulating blood that are critical for the achievement of hemostasis following tissue injury and, probably, for general maintenance of vascular integrity. The human circulation normally contains -2.5 x 108 platelets per ml, each -5 ,um3 in volume. Over the past 3 decades, much has been learned about the biochemical mechanisms and structural...
