Multimodal and multiscale strengthening mechanisms in Al-Ni-Zr-Ti-Mn alloy processed by laser powder bed fusion additive manufacturing (open access)

Multimodal and multiscale strengthening mechanisms in Al-Ni-Zr-Ti-Mn alloy processed by laser powder bed fusion additive manufacturing

Article describes how the unique thermokinetics of laser-powder bed fusion additive manufacturing has been exploited for development of a novel high strength Al-Ni-Ti-Zr-Mn alloy. The authors say that the addition of 0.5 wt% Mn leads to extraordinary improvement in ultimate tensile strength (502 MPa) and work hardening due to the activation of two Mn-induced strengthening mechanisms

Assembling Artificial Photosynthetic Models in Water Using β-Cyclodextrin-Conjugated Phthalocyanines as Building Blocks (open access)

Assembling Artificial Photosynthetic Models in Water Using β-Cyclodextrin-Conjugated Phthalocyanines as Building Blocks

Article describes how two water-soluble zinc(II) phthalocyanines substituted with two or four permethylated β-cyclodextrin (β-CD) moieties at the α positions have been utilized as building blocks for the construction of artificial photosynthetic models in water. The hydrophilic and bulky β-CD moieties not only can increase the water solubility of the phthalocyanine core and prevent its stacking in water but can also bind with a tetrasulfonated zinc(II) porphyrin (ZnTPPS) and/or sodium 2-anthraquinonesulfonate (AQ) in water through host–guest interactions.

Manipulating plasma thyroid hormone levels alters development of endothermy and ventilation in nestling red-winged blackbirds (open access)

Manipulating plasma thyroid hormone levels alters development of endothermy and ventilation in nestling red-winged blackbirds

Authors of the article propose that thyroid hormones play an important role in regulating development of endothermy during the nestling period in altricial birds. Their data suggests plasma thyroid hormone levels play an active role in the systemic development of endothermic capacity and the development of ventilatory control.

Collection Assessment Through DEI Lenses: Venturing into (nearly) uncharted waters

Presentation for a panel discussing UNT Libraries' journey to address systemic and systematic vestiges of oppression of socially and politically minoritized populations. For this purpose, the Collection Assessment Department is planning on evaluating the UNT Libraries’ collections, identifying sources of diverse materials, and connecting with our communities. They will conduct focus groups and pilot a method on one aspect of their collections. For this panel discussion, self-selected members of an advisory board for this project will discuss their individual motivations for and concerns about the project. It was presented at the 2022 Cross Timbers Library Collaborative Conference which was held virtually on July 29, 2022.

An experimental and modeling study on auto-ignition kinetics of ammonia/methanol mixtures at intermediate temperature and high pressure (open access)

An experimental and modeling study on auto-ignition kinetics of ammonia/methanol mixtures at intermediate temperature and high pressure

Article describes how a rapid compression machine has been applied to measure the ignition delay times of NH3/CH3OH mixtures covering pressures of 20 and 40 bar, equivalence ratios of 0.5, 1.0 and 2.0, and temperatures between 845 and 1100 K. Analysis of the pressure profiles shows three distinct ignition modes for NH3/CH3OH mixtures, facilitated by the pre-ignition heat release from NH3 consumption. A detailed mechanism for ignition of NH3/CH3OH fuel blends has been developed, capable of reproducing the ignition behavior of mixtures with reasonable accuracy.
