Low-GWP alternative refrigerant blends for HFC-134a :

, 2021
This project addresses the objectives of the Statement of Need number WPSON-17-20 No/Low Global Warming Potential Alternatives to Ozone Depleting Refrigerants. Its goal is to identify and demonstrate performance of low global-warming-potential (GWP), non-flammable refrigerants to replace HFC-134a in military environmental control units (ECUs).

Sustainable Materials Design With Multi‐Modal Artificial Intelligence

Advanced Science, EarlyView.
Critical mineral scarcity, high embodied carbon, and persistent pollution from materials processing intensify the need for sustainable materials design. This review frames the problem as multi‐objective optimization under heterogeneous, high‐dimensional evidence and highlights multi‐modal AI as an enabling pathway.

Who pollutes in Scotland? A prelude to an analysis of sustainability policies in a devolved context [PDF]

, 2001
The notion of sustainable development has begun to figure prominently in the regional, as well as the national, policy concerns of many industrialized countries. Indicators have typically been used to monitor changes in economic, environmental and social

High‐Throughput Screening and Interpretable Machine Learning for Rational Design of Bimetallic Catalysts for Methane Activation

Advanced Science, EarlyView.
ABSTRACT Methane's efficient catalytic removal is vital for sustainable development. Bimetallic catalysts, though promising for methane activation, pose a design challenge due to their complex compositional space. This work introduces an integrated framework that combines high‐throughput density functional theory (DFT) and interpretable machine ...

No way out? The double-bind in seeking global prosperity alongside mitigated climate change [PDF]

, 2012
In a prior study, I introduced a simple economic growth model designed to be consistent with general thermodynamic laws. Unlike traditional economic models, civilization is viewed only as a well-mixed global whole with no distinction made between ...

High‐Performance Recycling Biobased Photopolymers for 3D Printing

Advanced Science, EarlyView.
By using biobased phenols like eugenol, novel biobased photopolymers containing dissociative phenol‐carbamate bonds are designed for 3D printing. Meanwhile, a “mixed‐monomer assisted recycling” strategy is proposed to recycle the materials. The resulting materials not only achieve high‐performance and excellent chemical recyclability simultaneously ...

Fictitious time wave packet dynamics: I. Nondispersive wave packets in the quantum Coulomb problem

, 2009
Nondispersive wave packets in a fictitious time variable are calculated analytically for the field-free hydrogen atom. As is well known by means of the Kustaanheimo-Stiefel transformation the Coulomb problem can be converted into that of a four ...

AI in chemical engineering: From promise to practice

AIChE Journal, EarlyView.
Abstract Artificial intelligence (AI) in chemical engineering has moved from promise to practice: physics‐aware (gray‐box) models are gaining traction, reinforcement learning complements model predictive control (MPC), and generative AI powers documentation, digitization, and safety workflows.
