Physical and Surface Chemical Analysis of High-Quality Antimicrobial Cotton Fabrics Functionalized with CuO Gown from Different Copper Salts: Experimental and Theoretical Approach.

The emergence of harmful microorganisms poses a public health challenge. Antimicrobial cotton textiles with semiconductor oxides offer a promising solution to mitigate pathogen spread. Here, we study the physicochemical interactions between copper oxides (CuO) and cellulose in cotton fiber functionalized with these same oxides for antimicrobial properties.

A new species of the genus Liotyphlops Peters, 1881 (Serpentes: Anomalepididae) from the Caribbean coast of Honduras.

We describe a new species of the genus Liotyphlops from the Caribbean coast of Honduras in Nuclear Mesoamerica, a genus previously known only from Isthmian Mesoamerica and northern, central, and eastern South America. Our description is based on a single specimen found by chance. The new species differs from other congeners by unique combination of external morphological characteristics, specifically by the presence of three scales on the first vertical row of the dorsals, three supralabial scales, 425 dorsal scales, and dorsals in 22 series of uniformly pigmented scales across the body.

Major depression symptom severity associations with willingness to exert effort and patch foraging strategy.

Background: Individuals with major depressive disorder (MDD) can experience reduced motivation and cognitive function, leading to challenges with goal-directed behavior. When selecting goals, people maximize 'expected value' by selecting actions that maximize potential reward while minimizing associated costs, including effort 'costs' and the opportunity cost of time. In MDD, differential weighing of costs and benefits are theorized mechanisms underlying changes in goal-directed cognition and may contribute to symptom heterogeneity.

Development of antioxidant films based on anthocyanin microcapsules extracted from purple corn cob and incorporated into a chitosan matrix.

Biodegradable food packaging films were prepared from chitosan incorporated with microencapsulated anthocyanins powder (MAP) that was extracted from purple corn cob using the casting method. Anthocyanins extracts were microencapsulated with maltodextrin, gum arabic, and soy protein using a spray-drying method. The film based on chitosan and MAP (CHt@MAP) was prepared through citric acid cross-linking and plasticization with glycerol.

An imaging scheme to study the flow dynamics of co-flow regimes in microfluidics: implications for nanoprecipitation.

Co-flow microfluidics, in addition to its applications in droplet generation, has gained popularity for use with miscible solvent systems (continuous microfluidics). By leveraging the short diffusional distances in miniature devices, processes like nanomaterial synthesis can be precisely tailored for high-throughput production. In this context, the manipulation of flow regimes-from laminar to vortex formation, as well as the generation of turbulent and turbulent jet flows-plays a significant role in optimizing these processes.
