High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

This study investigated the oleogelation of cellulose bead dispersions in a sunflower oil oleogel made with solvent-transferred whey protein isolate. The microstructure and rheology of the mixed gels depended on the ratio of hydrated cellulose beads to proteins (9:1, 8:2, 7:3, and 1:1). Two gel stabilization mechanisms were identified.

Oleogelation was investigated to reduce the saturated fat content of vegan cheese. Oleogels were formulated using a range of oleogelators, oleogelator concentrations and oil phase compositions to study the effect that adjusting these parameters had on both oleogel and vegan cheese properties. Comparing oleogels at an equivalent mass basis of 20 wt%, phytosterol oleogels exhibited greater hardness (5.

Emulsifiers play an essential role in the flow behaviour of confectionery products such as chocolate. This research associated emulsifier adsorption onto sugar crystals and its effects on the flow properties of model sugar-in-oil suspensions. A new method to quantify emulsifier adsorption onto sugar crystals dispersed in oil was developed by exploiting the relationship between oil-water interfacial tension and unadsorbed emulsifier in the continuous oil phase.

Municipal wastewater treatment plants in China face significant challenges in effectively removing pollutants from low-strength wastewater with a low carbon-to-nitrogen (COD/N) ratio. This study proposes a novel approach incorporating porous polymers embedded with iron-carbon (PP-IC) into an activated sludge system to enhance treatment. The PP-IC accelerated the formation of densified activated sludge (DAS), characterized by small particle sizes (<200 μm), excellent settleability (sludge volume index: 61 mL/g), and improved pollutant removal efficiency, with total nitrogen and total phosphorus removal rates increasing by 14.
