One-dimensional nanostructures of lead and lead dioxide for application in lead-acid batteries
Fabrication of Pb and PbO2 nanostructures was undertaken with the aim of building low cost lead acid micro-batteries with high performance. Despite environmental problems and the relatively low specific energy in comparison with other galvanic generators, lead acid batteries are still extensively used in the field of energy accumulation, owing to a well known and reliable technology. Thus, it is of high technological interest to develop procedures for fabricating these devices at a micrometer scale or less. PbO2 nanowires were grown in different electrochemical deposition conditions leading to pure -PbO2, pure -PbO2 and mixture [1-2]. Several parameters, like temperature, electrolyte…
Understanding Factors Associated With Psychomotor Subtypes of Delirium in Older Inpatients With Dementia
Objectives Few studies have analyzed factors associated with delirium subtypes. In this study, we investigate factors associated with subtypes of delirium only in patients with dementia to provide insights on the possible prevention and treatments. Design This is a cross-sectional study nested in the "Delirium Day" study, a nationwide Italian point-prevalence study. Setting and participants Older patients admitted to 205 acute and 92 rehabilitation hospital wards. Measures Delirium was evaluated with the 4-AT and the motor subtypes with the Delirium Motor Subtype Scale. Dementia was defined by the presence of a documented diagnosis in the medical records and/or prescription of acetylcholine…
