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
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.

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.

On Polish groups admitting non-essentially countable actions
Article addresses the question whether every Polish group that is not locally compact admits a Borel action on a standard Borel space whose associated orbit equivalence relation is not essentially countable. The authors e answer this question positively for the class of all Polish groups that embed in the isometry group of a locally compact metric space.

ICT in Higher Education: An Exploration of Practices in Malaysian Universities
Article investigating the use of information and communication technologies (ICTs) in education. To investigate this issue, the technology adoption and gratification (TAG) model was validated and used to examine Malaysian university teachers' adoption and gratification of ICT for teaching and research purposes and then used to investigate the moderating effect of universities in different regions. This paper confirms the utility of the TAG model for comparing teachers' adoption and gratification of ICT.

Modeling and predicting evacuation flows during hurricane Irma
This article proposes a method to model evacuation flows and reveal the patterns of evacuation flows at different spatial scales. First, the authors present a method to characterize evacuation flows at different geographic scales: the state level, considering evacuation flows across southern states affected by Irma; the urban/rural area level, and the county level. Then they demonstrate results on the predictability of evacuation flows in the most affected state, Florida, by using the following environmental factors: the destructive force of the hurricane, the socioeconomic context, and the evacuation policy issued for counties. The results presented in this paper can help decision makers to better understand population evacuation behaviors given certain environmental features, which in turn will aid in the design of efficient and informed preparedness and response strategies.
