Selective extraction of lithium over alkali and alkaline earth ions by synergistic solvent extraction.

Direct lithium extraction (DLE) from natural surface and geothermal brines is very challenging due to the low ratio of lithium to other metals, and the lack of suitable materials that bind lithium with sufficiently high selectivity. In this paper, a synergistic solvent extraction system is described that comprises a liquid ion exchanger (saponified bis(2-ethylhexyl)dithiophosphoric acid) and a lithium-selective ligand (2,9-dibutyl-1,10-phenanthroline) in an aliphatic diluent. The extraction mechanism was investigated and was confirmed to involve the binding of lithium to the selective ligand, while the liquid ion exchanger facilitates the transfer of metal ions from the aqueous to the organic phase.

Explanatory variables of objectively measured physical activity, sedentary behaviour and sleep in adults with type 1 diabetes: A systematic review.

Aims: This systematic review aimed to summarize knowledge on explanatory variables of PA, SB and sleep in adults with T1D to support the development of healthy lifestyle interventions.

Methods: A systematic search of four databases (PubMed, Web of Science, Scopus and Embase) was performed. Only objective measurements of PA, SB and sleep were included and all explanatory variables were classified according to the socio-ecological model (i.

Physical activity and sedentary behaviour in relation to body composition, estimated insulin sensitivity and arterial stiffness in adults with type 1 diabetes.

Aims: To examine the association of daily PA levels and sedentary behaviour with body composition, estimated insulin sensitivity, and arterial stiffness in adults with type 1 diabetes (T1D).

Methods: Cross-sectional study in adults with T1D (n = 54). PA levels (daily steps, and time in moderate-to-vigorous intensity PA (MVPA)) and sedentary behaviour were measured using accelerometry for 7 days (McRoberts® DynaPort MoveMonitor).

Nature lifts when feeling low: Daily high and low awe nature clips decrease repetitive negative thinking and dampening and increase subjective happiness in adults.

Exposure to nature can enhance mental well-being, making nature-based interventions promising for the treatment and prevention of mental health problems like depression. Given the decreased self-focus and sense of self-diminishment associated with awe, the present study investigated the impact of exposure to awe-evoking nature on two key risk and maintenance factors of depression-repetitive negative thinking (RNT) and dampening of positive feelings-and on subjective happiness. In a randomized controlled trial, we tested the effects of exposure to awe-evoking nature clips through a 1-week intervention, consisting of watching a 1-min clip on a daily basis of either awe-evoking (n high awe = 108) or more mundane nature scenes (n low awe = 105).

Physiotherapist- and patient-reported barriers to guideline implementation of active physiotherapeutic management of low back pain: A theory-informed qualitative study.

Background And Objective: Adoption of low back pain (LBP) guidelines in physiotherapeutic management is a well-documented problem. Thereby, an in-depth understanding of the barriers to implement an active approach for both patients and physiotherapists is needed.

Design: Semi-structured interviews were conducted with physiotherapists and patients with non-specific LBP.
