Abstract

Hip fractures are the most common cause of hospital admission to orthopaedic departments in Europe and they generate a major health problem. Therefore, it is of great interest to identify additional risk factors that will help us to better understand the pathophysiology of these fractures and improve our preventive capacity. There is sufficient data to support the theory of modulation of bone mass by gut microbiota (osteomicrobiology); however, there is a lack of human clinical studies directly linking microbiota to hip fracture risk.

Abstract

Developing new materials for the separation of gas mixtures is a key subject in setting up a circular economy. In this work, we report the synthesis and application of novel polymeric membranes, based on polymerized ionic liquids (PILs), to be used for CO2 separation from different gas pairs. Phosphonium-based PILs have been copolymerized within an original acrylate formulation that allowed the development of dense membranes able to overcome some of the main limitations related to ionic liquid membranes. Thereby, a collection of phosphonium ionic liquids has been investigated by evaluating the influence of the alkyl chain length and anion type on membrane structure and properties by employing a series of different chemo-physical characterization techniques. The membranes showed a marked preference toward CO2 permeation in the wet state, which simulates the conditions occurring with many CO2-containing gas streams, with two of the studied membranes exceeding the Robeson upper bound for the CO2/H2 gas pair.

Abstract

A dynamic nuclear magnetic resonance study was made of the adamantylideneadamantane/Br2 system as a function of temperature and excess (Br2). Line shape analysis of the spectral region between delta 2.1 and 2.6 was used to investigate the bromine site exchange rate constants. The results indicated that the dynamic condition occurred through the rate-limiting dissociation of a 1:1 charge-transfer complex to liberate Ad=Ad + Br2.
