Two-dimensional ion chromatography for the separation of ionic organophosphates generated in thermally decomposed lithium hexafluorophosphate-based lithium ion battery electrolytes.

A two-dimensional ion chromatography (IC/IC) technique with heart-cutting mode for the separation of ionic organophosphates was developed. These analytes are generated during thermal degradation of three different commercially available Selectilyte™ lithium ion battery electrolytes. The composition of the investigated electrolytes is based on 1M lithium hexafluorophosphate (LiPF6) dissolved in ethylene carbonate/dimethyl carbonate (50:50wt%, LP30), ethylene carbonate/diethyl carbonate (50:50wt%, LP40) and ethylene carbonate/ethyl methyl carbonate (50:50wt%, LP50).

A preliminary investigation of the brain injury family intervention: impact on family members.

Primary Objective: To evaluate the benefits of the Brain Injury Family Intervention (BIFI) for families of persons with acquired brain injury and identify factors related to outcomes.

Research Design: Pre-test, post-test design with outcomes measured immediately after and 3 months following intervention.

Methods And Procedures: Family members and survivors participated in five 2-hour sessions over 10 weeks which included discussions of typical effects of brain injury, coping with loss and change, managing stress and intense emotions, effective problem-solving, setting reasonable goals and taking care of one's self.

Depression in the elderly after traumatic brain injury: a systematic review.

Primary Objective: To systematically review recent research published in peer-reviewed journals that focus on depression in the elderly with TBI. To better understand the prevalence of depression in the elderly after TBI and to note any differences or similarities between the elderly and their younger counterparts. Explore depression in the general elderly population and depression in the overall TBI population to better understand depression in the elderly after TBI.
