Femtoliter Batch Reactors for Nanofluidic Scattering Spectroscopy Analysis of Catalytic Reactions on Single Nanoparticles

Small Methods, EarlyView.
A transient 4.8 femtoliter batch reactor is created within a micro‐ and nanofluidic system with the help of symmetric N2‐streams. The catalytic activity of a single lithographic gold nanoparticle in the reactor is monitored via nanofluidic scattering spectroscopy (NSS), revealing dynamic chemical changes of Fluorescein in the presence of NaBH4 as a ...

Ex–ante LCA for circular resource management of liquid digestate, by predictive modeling of algae–bacterial processes

Journal of Industrial Ecology, EarlyView.
Abstract The simplest method for treating liquid digestate, which involves directly spreading it over local agricultural land, is facing scrutiny due to the challenges of transporting large volumes and the environmental risks posed by nitrogen and phosphorus pollutants.

Recent Advances in PBAT (Nano) Composite Materials for Food Packaging: A Comprehensive Review

Journal of Applied Polymer Science, Volume 142, Issue 28, July 20, 2025.
Poly(butylene adipate‐co‐terephthalate) (PBAT) is the most commonly used plastic. PBAT‐based (nano) composites provide a lot of potential as food wrapping. The preparation of plastics based on PBAT composites is described. PBAT materials' distinctive properties lead to suitability for application in food packaging.

Reinforcement learning for optimal control of stochastic nonlinear systems

AIChE Journal, Volume 71, Issue 7, July 2025.
Abstract A reinforcement learning (RL) approach is developed in this work for nonlinear systems under stochastic uncertainty. A stochastic control Lyapunov function (SCLF) candidate is first constructed using neural networks (NNs) as an approximator to the value function, and then a control policy designed using this SCLF is developed to ensure the ...

Reaction Kinetics of NH2 With H2CO and CH3CHO: Modeling Implications for NH3‐Dual Fuel Blends

International Journal of Chemical Kinetics, Volume 57, Issue 7, Page 403-416, July 2025.
ABSTRACT Carbon‐free fuels like ammonia (NH3) and hydrogen (H₂) offer significant potential in combating global warming by reducing greenhouse gas emissions and moving toward zero carbon emissions. Over the past few years, our research has focused on understanding the combustion behavior of carbon‐neutral and carbon‐free fuels.

Discriminating neutrino mass models using Type II seesaw formula

, 2004
In this paper we propose a kind of natural selection which can discriminate the three possible neutrino mass models, namely the degenerate, inverted hierarchical and normal hierarchical models, using the framework of Type II seesaw formula.

Prediction of the Methane Yield From Extensively Managed, Flower‐Rich Fen Grassland Based on NIRS Data

GCB Bioenergy, Volume 17, Issue 7, July 2025.
Biogas production from grasslands in Europe is important for sustainable energy, but predicting biogas yield from mixed, flower‐rich grasslands has been challenging due to variable biomass quality and limitations of existing models. This study analyzed flower‐rich fen grassland biomass, finding it to have high fiber and protein content, and ...
