A tandem catalytic ensemble of solid-state molecular organometallic (SMOM) crystalline pre-catalysts are deployed under batch or flow conditions for the ethene to propene process (ETP). These catalysts operate at ambient temperature and low pressure, via sequential ethene dimerization, butenes isomerization and cross-metathesis. Under flow conditions the on-stream ethene conversion (55%), initial propene selectivity (92%), stability (71% selectivity after 7 hrs) and low temperature/pressures are competitive with the best-in-class heterogenous systems, marking a new, in crystallo, approach to ETP.

However, these technologies are often difficult to use and lack prosody. Surface electromyographic-based silent speech interfaces are novel communication systems that overcome many of the shortcomings of traditional alaryngeal speech and have the potential to seamlessly incorporate individualized prosody.

This study investigated the effect of broad-spectrum micronutrients (BSM; vitamins and minerals), used to treat antenatal depression (NUTRIMUM trial), on birth outcomes.

Background: Hypertension is a global health issue causing increased cardiovascular morbidity and mortality. Adherence to prescribed medication is a crucial factor in obtaining targeted outcomes, and fixed-dose combined antihypertensive pills (FCAPs) have been shown to help combat difficulties associated with polypharmacy management. This study investigated the influence of combination antihypertensives on blood pressure (BP) management.
