Local delivery of therapeutic ions from bioactive mesoporous glasses (MBGs) is postulated as one of the most promising strategies for regenerative therapy of critical bone defects. Among these ions, Sr cation has been widely considered for this purpose as part of the composition of MBGs. MBGs of chemical composition 75SiO-25-x CaO-5PO-xSrO with x = 0, 2.

A common intuition in thermodynamics is that bubbles can spontaneously grow in unstable liquids, which will be detrimental to a variety of physical and chemical processes, such as evaporation-induced self-assembly and electrocatalysis. Here, we show that this common intuition can be significantly reversed by demonstrating a suppression of bubbles in unstable active liquids induced by fast evaporation, which is in contrast to the bubble growth in passive liquids. Such anomalous bubble suppression can be attributed to an activity-induced inversion of pressure difference between bubbles and their surrounding liquid.

Passive daytime radiative cooling is receiving more and more attention as a cooling method that does not consume energy to cool objects. However, most radiative cooling materials require the mixing of multiple particles, which increases the manufacturing process requirements. Most radiative cooling materials are susceptible to outdoor abrasion, pollution, and UV exposure, which leads to decreased performance.

Hypothesis: Supra-particle formation by evaporation of an aqueous aerosol droplet containing nano-colloidal particles is challenging to investigate but has significant applications. We hypothesise that the Peclet number, Pe, which compares the effectiveness of evaporation-induced advection to that of colloidal diffusion, is critical in determining supra-particle morphology and can be used to predict the dried morphology for droplet containing polydisperse nanoparticles.
Experiments: Sterically-stabilized diblock copolymer nanoparticles were prepared via polymerization-induced self-assembly (PISA).
