Dynamic Motions of Topological Defects in Nematic Liquid Crystals under Spatial Confinement (open access)

Dynamic Motions of Topological Defects in Nematic Liquid Crystals under Spatial Confinement

Article discusses how topological defects (TDs) have become a sensational topic due to their significant influence on the unusual optical and physiochemical characteristics of the material. Here, authors assert how nematic liquid crystals confined in a cell exhibiting surfaces with periodic anchoring conditions containing surface topography are relied on.

Harnessing nanofiber alignment and pore size to promote stem cell self-renewal and differentiation (open access)

Harnessing nanofiber alignment and pore size to promote stem cell self-renewal and differentiation

Article describes how stem cell therapy holds immense potential for regenerative medicine, but its applications are limited due to the loss of pluripotency during in vitro expansion. This study reveals that the arrangement of electrospun fibers aligns with the distribution and strength of the electric field through both experimentation and simulation.

Post-imprinting modification: electrochemical and scanning electrochemical microscopy studies of a semi-covalently surface imprinted polymer (open access)

Post-imprinting modification: electrochemical and scanning electrochemical microscopy studies of a semi-covalently surface imprinted polymer

Authors of the article describe a post-imprinting modification of the imprinted molecular cavities for electrochemical sensing of a target protein. These mesoporous cavities were modified with a ferrocene ‘electrochemical’ tracer for electrochemical transduction of the target protein recognition.

Accessible History: Putting a Century of The Chronicles of Oklahoma Online

Presentation sharing the project workflows for digitizing back issues of The Chronicles of Oklahoma. It has been published since 1921, and in 2020, the Oklahoma Historical Society partnered with the UNT Digital Library to make the back issues freely available through The Gateway to Oklahoma History. It was presented at the 2023 NASIG Conference held May 22-25, 2023 in Pittsburgh, Pennsylvania.

Sibling Aggression, Feeding Rates, and Hatch Rank of Nestling Red-Shouldered Hawks (Buteo lineatus) (open access)

Sibling Aggression, Feeding Rates, and Hatch Rank of Nestling Red-Shouldered Hawks (Buteo lineatus)

Article describes how, in many raptor species, hatching asynchrony results in a size hierarchy among nestlings, which may facilitate brood reduction by means of sibling aggression-induced mortality, especially in times of low food resources. The authors studied the influence of hatch rank, brood size, and brood age on aggression and feeding rates among Red-shouldered Hawk (Buteo lineatus) nestlings in suburban southwestern Ohio.

The refractive index of a single atom experienced by a single photon (open access)

The refractive index of a single atom experienced by a single photon

Article describes how the refractive index of a system is often viewed as the collective response of a medium to an electromagnetic field. By studying the propagation of a single photon interacting with a two-level atom, the authors examine the dispersion behavior, calculate the phase and group velocity of the photon wave packet, and further analyze the dispersion experienced by the photon.

Multifaceted Shape Memory Polymer Technology for Biomedical Application: Combining Self-Softening and Stretchability Properties (open access)

Multifaceted Shape Memory Polymer Technology for Biomedical Application: Combining Self-Softening and Stretchability Properties

Article describes how thiol-ene polymers are a promising class of biomaterials with a wide range of potential applications, including organs-on-a-chip, microfluidics, drug delivery, and wound healing. This study investigated the incorporation of di-acrylate chain extenders to improve the stretchability and conformability of those flexible thiol-ene polymers.
