Atropselektive Synthese axial‐chiraler Biaryle

Abstract: Eine rotationsgehinderte und dadurch stereogene Biarylachse ist das strukturell und stereochemisch entscheidende Element einer standig wachsenden Zahl von Naturstoffen, chiralen Auxiliaren und Katalysatoren. Daher ist es nicht uberraschend, dass im letzten Jahrzehnt bedeutende Fortschritte in der asymmetrischen Synthese axial-chiraler Biaryle erzielt worden sind. Neben dem klassischen Zugangsweg, der direkten Aryl-Aryl-Kupplung, sind innovative Konzepte entwickelt worden, in denen die asymmetrische Information in ein schon vorhandenes, aber nicht optisch aktives – symmetrisches oder konfigurativ labiles – Biaryl eingefuhrt oder eine Aryl-C-Einfachbindung stereoselektiv in eine Achse umgewandelt wird. In diesem Aufsatz werden die Strategien nach den zugrunde liegenden Konzepten klassifiziert, und ihre Anwendungsbreite und ihre Beschrankungen werden anhand ausgewahlter Beispiele kritisch beurteilt. Ferner werden die Voraussetzungen fur das Auftreten von Axialchiralitat diskutiert.

Duration of life-threatening antecedents prior to intensive care admission

Abstract: Objective: To document the characteristics and incidence of serious abnormalities in patients pri- or to admission to intensive care units. Design and setting: Prospec- tive follow-up study of all patients admitted to intensive care in three acute-care hospitals. Patients: The study population totalled 551 pa- tients admitted to intensive care: 90 from the general ward, 239 from op- erating rooms (OR) and 222 from the Emergency Department (ED). Measurements and results: Patients from the general wards had greater severity of illness (APACHE II me- dian 21) than those from the OR (15) or ED (19). A greater percentage of patients from the general wards (47.6%) died than from OR (19.3%) and ED (31.5%). Patients from the general wards had a greater number of serious antecedents before admis- sion to intensive care 43 (72%) than those from OR 150 (64.4%) or ED 126 (61.8%). Of the 551 patients 62 had antecedents during the period 8-48 h before admission to intensive care, and 53 had antecedents both within 8 and 48 h before their admis- sion. The most common antecedents during the 8 h before admission were hypotension (n=199), tachycardia (n=73), tachypnoea (n=64), and sud- den change in level of consciousness (n=42). Concern was expressed in the clinical notes by attending staff in 70% of patients admitted from the general wards. Conclusions: In over 60% of patients admitted to intensive care potentially life-threatening ab- normalities were documented during the 8 h before their admission. This may represent a patient population who could benefit from improved re- suscitation and care at an earlier stage.

Understanding social innovation: a provisional framework

Abstract: This article examines what we understand by the concept of social innovation. Historically, the emphasis has been on how to translate innovations in science and technology into commercial applications. Typically, company survival is explained in terms of an 'innovation imperative' in the pursuit of profits and competitive advantage. In contrast, social innovations are triggered by an interest in improving the well-being of people in society. Social rather than economic concerns are the main driver in the development and application of new ideas to solving problems and improving social conditions. We examine the relationship between social, business and technical dimensions and develop a provisional framework for making sense of social innovation.

Sn4+xP3 @ Amorphous Sn-P Composites as Anodes for Sodium-Ion Batteries with Low Cost, High Capacity, Long Life, and Superior Rate Capability

Abstract: Sn4+x P3 @ amorphous Sn-P composites are a promising cheap anode material for sodium-ion batteries with high capacity (502 mA h g(-1) at a current density of 100 mA g(-1)), long cycling stability (92.6% capacity retention up to 100 cycles), and high rate capability (165 mA h g(-1) at the 10C rate).
