The Rate Performance of Two-Dimensional Material-Based Battery Electrodes May Not Be as Good as Commonly Believed

A high performance lithium-ion battery using LiNa0.02K0.01FePO4/C as cathode material and anatase TiO2 nanotube arrays as anode material

In this paper we report on a lithium ion battery (LIB) based on improved olivine lithium iron phosphate/carbon (LiFePO4/C) as cathode material and LiNa0.02K0.01FePO4/C  synthesized by sol-gel method and TiO2 nanotube arrays (TNAs) with an anatase phasesynthesized through anodization of Ti foil as an anode electrode. Crystallographic structure and surface morphology of the cathode and anode mate...

Bar codes may have poorer error rates than commonly believed.

By most accounts (1 ), the development of bar code technology is credited to 2 graduate students at Drexel University. In 1948, Bernard Silver had overheard the president of a local grocery chain asking a dean at the University whether they could develop a system to read product information at checkout. Silver told his colleague Norman Woodland of this request. After one failed idea involving u...

Rickettsial Diseases in India: Not as Uncommon as Believed.

Role of Intrinsic Muscle Atrophy in the Etiology of Claw Toe Deformity in Diabetic Neuropathy May Not Be as Straightforward as Widely Believed

OBJECTIVE Clawing of the toes in the diabetic neuropathic foot is believed to be caused by muscle imbalance resulting from intrinsic muscle atrophy. However, experimental data that support this mechanism are lacking. The aim of this study was to evaluate this hypothesis using magnetic resonance imaging (MRI). RESEARCH DESIGN AND METHODS In 20 neuropathic diabetic patients, 10 with claw toe de...

PEDOT:PSS as multi-functional composite material for enhanced Li-air-battery air electrodes

UNLABELLED We propose PEDOT PSS as a multi-functional composite material for an enhanced Li-air-battery air electrode. The PEDOT PSS layer was coated on the surface of carbon (graphene) using simple method. A electrode containing PEDOT PSS-coated graphene (PEDOT electrode) could be prepared without binder (such as PVDF) because of high adhesion of PEDOT PSS. PEDOT electrode presented co...
