'I can't relate to it': Exploring autistic and non-autistic adults' perceptions of the Australian Physical Activity and Sedentary Behaviour Guidelines.

Background: Despite sufficient physical activity (PA) being strongly associated with better health outcomes, half of the Australian population does not meet the Australian PA and Sedentary Behaviour Guidelines. This shortfall is more pronounced among autistic adults, who exhibit poorer health outcomes and lower PA levels than non-autistic adults. Despite these disparities, there is a limited understanding of how autistic and non-autistic individuals perceive and interpret the PA guidelines.

An automatic multi-precursor flow-type atomic layer deposition system.

Designs for two automated atomic layer deposition (ALD) flow reactors are presented, and their capabilities for coating additively manufactured (AM) metal prints are described. One instrument allows the coating of several AM parts in batches, while the other is useful for single part experiments. To demonstrate reactor capabilities, alumina (Al2O3) was deposited onto AM 316L stainless steel by dosing with water (H2O) vapor and trimethylaluminum (TMA) and purging with nitrogen gas (N2).

The interaction of size-selected Ru clusters with RF-deposited TiO: probing Ru-CO binding sites with CO-temperature programmed desorption.

Small Ru clusters are efficient catalysts for chemical reactions such as CO hydrogenation. In this study 3-atom Ru clusters were deposited onto radio frequency (RF)-deposited TiO which is an inexpensive, nanoparticulate form of TiO. TiO substrates are notable in that they form strong metal-substrate interactions with clusters.

Sn-modification of Pt/alumina model catalysts: Suppression of carbon deposition and enhanced thermal stability.

An atomic layer deposition process is used to modify size-selected Pt/alumina model catalysts by Sn addition, both before and after Pt cluster deposition. Surface science methods are used to probe the effects of Sn-modification on the electronic properties, reactivity, and morphology of the clusters. Sn addition, either before or after cluster deposition, is found to strongly affect the binding properties of a model alkene, ethylene, changing the number and type of binding sites, and suppressing decomposition leading to carbon deposition and poisoning of the catalyst.
