Importance of Morphology of Layered Double Hydroxide in Electrochemical Energy Storage and Catalysis.

The development of nanomaterials for energy storage and conversion has always been important. Layered double hydroxide (LDH) is a promising material due to its high capacity, tunable composition and easy synthesis. In this work, the morphology of NiCo-LDH is tuned with surfactants including sodium dodecyl sulfate (SDS) and cetyltrimethylammonium bromide (CTAB), and investigated the correlation between morphology and electrochemical properties.

Spinal epidural hematoma occurrence in the absence of known risk factors: a case series.

Spinal epidural hematoma in the absence of coagulopathy or anticoagulation therapy is an extremely rare occurrence, with a reported incidence of less than 1 in 1 million. We present seven cases of documented epidural hematoma in the absence of coagulopathy or anticoagulation therapy to alert the clinician to consider spinal or epidural hematoma when suspicious signs and symptoms are present after neuraxial block in the absence of coagulopathy or anticoagulation therapy. The need for immediate diagnosis and therapy is emphasized as the only potential for meaningful recovery.
