Enhanced lithium battery with polyethylene oxide-based electrolyte containing silane-Al2 O3 ceramic filler.

A solid polymer electrolyte prepared by using a solvent-free, scalable technique is reported. The membrane is formed by low-energy ball milling followed by hot-pressing of dry powdered polyethylene oxide polymer, LiCF3 SO3 salt, and silane-treated Al2 O3 (Al2 O3 -ST) ceramic filler. The effects of the ceramic fillers on the properties of the ionically conducting solid electrolyte membrane are characterized by using electrochemical impedance spectroscopy, XRD, differential scanning calorimeter, SEM, and galvanostatic cycling in lithium cells with a LiFePO4 cathode.

Clinical and immunopathological spectrum of paraneoplastic pemphigus.

Background: Paraneoplastic pemphigus (PNP) is a rare life-threatening autoimmune bullous disorder. The clinical picture is often polymorphous and blisters may be absent. Autoantibodies are directed against several target antigens, including plakins and desmogleins.

Efficiency of topical imiquimod 5% cream in the management of chronic radiation dermatitis with multiple neoplasias.

The immune response modifier imiquimod 5% cream (Aldara) was locally applied to an extensive thoracic chronic radiation dermatitis for 2 weeks on a once daily basis. After moderate to severe irritative reactions with erythema and crusted erosions, areas cleared up within 4 weeks. The patient has now been in complete remission for 2 years.
