AIChE Journal, Volume 72, Issue 6, June 2026.Abstract Bayesian estimation enables uncertainty quantification, but analytical implementation is often intractable. As an approximate approach, the Markov Chain Monte Carlo (MCMC) method is widely used, though it entails a high computational cost due to frequent evaluations of the likelihood function.

Enhancing Hydrogen Storage in Carbon‐Substituted Beryllium Nitride: A DFT‐Based Investigation
Energy Storage, Volume 8, Issue 4, June 2026.Carbon‐substituted BeN4 monolayers enable efficient hydrogen storage, achieving 6.02 wt% uptake with moderate adsorption energy (−0.24 eV) and near‐ambient desorption temperature (308 K). These results highlight BeN4 as a promising candidate for practical hydrogen storage applications.

Drivers of Greenhouse Gas Emissions in Tropical Riverine Systems Across a Gradient of Human Impact
International Review of Hydrobiology, Volume 111, Issue 1, June 2026.ABSTRACT Tropical lotic ecosystems are important sources of greenhouse gas emissions, yet the magnitude and variability of such emissions remain poorly constrained. Here, we quantified spatial and short‐term temporal variability of carbon dioxide (CO2) and methane (CH4) fluxes across tropical riverine systems spanning a gradient of human impact, while ...
