The Influence of Ni Content in NixCoy‐BDC Metal‐Organic Frameworks on Catalytic Activity for Hydrogen Generation from Sodium Borohydride

open access: yesChemCatChem, Volume 18, Issue 11, 15 June 2026.
ABSTRACT Mono‐ and bimetallic Ni/Co‐based metal–organic frameworks (MOFs) coordinated with 1,4‐benzenedicarboxylate were successfully synthesized via a solvothermal approach and characterized by PXRD, FTIR, TGA, SEM–EDS, TEM, BET, and XPS. Fine control over the Ni:Co molar ratio enabled systematic modulation of the structural and electronic properties ...

Seascape connectivity and the influence of predation risk on the movement of fishes inhabiting a back‐reef ecosystem

open access: yesEcosphere, Volume 9, Issue 4, April 2018., 2018
Abstract The mangrove–seagrass–patch reef (MSP) ecosystem serves as the principal back‐reef nursery for many reef fishes in the Caribbean, but the functional roles of habitats that form this seascape remain unclear. We assessed ecosystem and trophic connectivity of two common reef fishes (schoolmaster, Lutjanus apodus; white grunt, Haemulon plumierii ...

Marine litter can shift sea turtle nests toward the shoreline

open access: yesOikos, Volume 2026, Issue 6, June 2026.
Marine litter is an emerging threat to sea turtle rookeries, yet its effects on nesting behaviour remain poorly understood. In this study, we investigated how macro‐litter accumulation on beaches influences the spatial distribution of loggerhead turtle Caretta caretta nests on Boa Vista Island, Cabo Verde.

Tropical Atlantic Contributions to Strong Rainfall Variability Along the Northeast Brazilian Coast

open access: yesAdvances in Meteorology, Volume 2015, Issue 1, 2015., 2015
Tropical Atlantic (TA) Ocean‐atmosphere interactions and their contributions to strong variability of rainfall along the Northeast Brazilian (NEB) coast were investigated for the years 1974–2008. The core rainy seasons of March‐April and June‐July were identified for Fortaleza (northern NEB; NNEB) and Recife (eastern NEB; ENEB), respectively.

Hybrid Reaction–Diffusion Epidemic Models: Dynamics and Emergence of Oscillations

open access: yesMathematical Methods in the Applied Sciences, Volume 49, Issue 5, Page 4074-4095, 30 March 2026.
ABSTRACT In this paper, we construct a hybrid epidemic mathematical model based on a reaction–diffusion system of the SIR (susceptible‐infected‐recovered) type. This model integrates the impact of random factors on the transmission rate of infectious diseases, represented by a probabilistic process acting at discrete time steps.

Colors, Position, and Harmonies in Frank Lloyd Wright's Taliesin Palette

open access: yesColor Research &Application, Volume 51, Issue 1, January/February 2026.
Frank Lloyd Wright's Taliesin pallete NCS variables collage. Source: Maria Fernanda Pilotto Brandi. ABSTRACT This research analyzes the colors and their positions in Frank Lloyd Wright's 1955 Taliesin palette, examining whether their proximity forms harmonious sets based on predefined parameters. The study will use the Natural Color System (N.C.S.) and

Fire‐induced disturbances in Malpighiaceae sequential flowering: Implications for pollination services and plant reproductive success

open access: yesPlant Species Biology, Volume 41, Issue 1, January 2026.
Our study demonstrates that fire has a strong influence on flowering phenology and reproductive dynamics in Malpighiaceae species from the Brazilian Cerrado. Specifically, fire triggered an earlier onset of flowering and promoted a more synchronous and widespread blooming, resulting in a temporary surge in floral resource availability. This increase in
