A combined machine learning-Physics-based approach for the thermodynamic design of complex systems is introduced and applied....

The paper analyzes the relationships among acid–base interactions in various oxide systems and their thermodynamics. Extensive data on enthalpies of solution of binary oxides in oxide melts of several compositions, obtained by high-temperature oxide melt solution calorimetry at 700 and 800 °C, are systematized and analyzed. Oxides with low electronegativity,...

In this review, the authors conducted benchmarks for three thermodynamic models to analyze PSA-based medical oxygen concentrator (MOC) systems to allow for optimization and operational flexibility. PSA oxygen generator plants are good medical-grade oxygen sources, a crucial tool in healthcare from the primary to the tertiary level. However, they must...

Background: The nonsteroidal anti-inflammatory medication meloxicam (MLX) belongs to the oxicam family and is used to reduce inflammation and pain. The aim of this study was to improve MLX's dispersibility and stability by producing it as a liquid self-microemulsifying drug delivery system since it is practically insoluble in water. Methods:...

Owing to the continuous increasing of steel strength, mechanical properties including toughness and fatigue performance are becoming increasingly sensitive to inclusions in ultra-high strength steel. Rare-earth treatment is considered as an effective method to reduce the harmful effects of inclusions, but is rarely applied in secondary-hardening steel. In the present...

Programmable DNA motifs are developed for biosensing and information encryption....

Cells are expert cooperators and collaborators. To maintain tissue health, cells talk to each other, exert pressure on each other, and kick out cells that are not contributing to the overall well-being of the collective. When it's time to get rid of a cell, the collective group initiates a process...

We study the response of chemical reaction networks driven far from equilibrium to logarithmic perturbations of reaction rates. The response of the mean number of a chemical species is observed to be quantitively limited by number fluctuations as well as the maximum thermodynamic driving force. We prove these trade-offs for...

TU Wien (Austria)A quantum version of the third law of thermodynamics formulated by scientists at Austria's Technical University of Wien (TU Wien) resolves contradictions between deleting information perfectly and cooling to absolute zero degrees Fahrenheit (-273.15 degrees Celsius). TU Wien's Marcus Huber said, "We found that quantum systems can be...

LiquidPiston's patented thermodynamic cycle is making engineering history – and they're taking investors while they do it....

This breakthrough in visualization supports their efforts to squeeze...

With a grant from the Office of Naval Research, MIT researchers aim to design novel high-performance steels, with potential applications including printed aircraft components and ship hulls....
