Green synthesis of olefin-linked covalent organic frameworks for hydrogen fuel cell applications

Description: This article creates a green strategy to fabricate a highly crystalline olefin-linked pyrazine-based covalent organic framework (COF) with high robustness and porosity under solvent-free conditions. This study opens up new possibilities for the green synthesis of advanced materials and provides important guidance for the rational design and synthesis of polymeric materials for proton-exchange membrane fuel cell applications.

The Perils of Complexity: A multi-stage study to determine necessary images for digitized scrapbook representation

Description: Presentation on a multi-stage study to assess national trends and user preferences for scrapbook representation undertaken by librarians at the University of North Texas. The stages of this study included a review of national trends in scrapbook digitization, as seen in the Digital Public Library of America; a paper-prototyping-inspired, in-person user study; and an online survey of user preferences. The results of this research have enabled the implementation of clear guidelines at the University of North Texas for scrapbook digitization that accounts for the user experience rather than strictly relying on personal opinion or local librarian consensus. It was presented at the Visual Resource Association Annual Conference held on March 22-26, 2021.

Carrier photodynamics in 2D perovskites with solution-processed silver and graphene contacts for bendable optoelectronics

Description: Article reporting on the inkjet printed, direct contact study of solution-processed, 2D perovskite-based photodetectors (PDs) formed on flexible PI substrates. Silver (Ag) and graphene (Gr) inks have been engineered to serve as efficient electrical contacts for solution-processed two-dimensional (2D) organo-halide (CH3(CH2)3NH3)2(CH3NH3)n−1PbnI3n+1 (n = 4) layered perovskites, where all inkjet-printed heterostructure PDs were fabricated on polyimide (PI) substrates.

Using the Lonsdorf model for estimating habitat loss and fragmentation effects on pollination service

Description: Article examining the effects of habitat loss and fragmentation on pollination separately according to the Lonsdorf model. Results show that the effects of habitat loss and fragmentation on pollination are completely different at the landscape and farm levels. This article shows that using the Lonsdorf model could lead to confusing results for the landscape ecologists and farmers who want to reduce the adverse effects of fragmentation on their products by creating new forest patches.

Bioresorbable stent to manage congenital heart defects in children

Description: This article assembles large, pediatric-sized stents (Ø10 - Ø20 mm) from poly(L-lactide) fibers (DH-BDS) at two thicknesses, 250 µm and 300 µm. DH-BDS exhibiting hoop strength similar to metal stents and demonstrating minimal degradation and strength loss over the first year before completely disappearing within 3 to 4.5 years show promise as a pediatric interventional alternative to current strategies.
