Mechanical chemistry: The new theory describes acceleration of reaction speed.
The mechanical force applied to the ball mill enhances the mixture of reactions by reducing the thickness of the rich phase. Credit: RSC Mechacen Chemistry (2024). Doi: 10.1039/D4MR00091a In contrast to the conventional organic synthesis, mechanical chemistry does not ultimately use a solvent that becomes industrial waste. Therefore, mechanical chemicals are environmentally friendly and can use organic synthesis using reactions…

Experimentally verifying the relationship between quantum theory and information theory
With the help of a new experiment, researchers from Linköping University and elsewhere have succeeded in confirming a decade of theoretical research linking information theory with the complementarity principle, one of the most fundamental aspects of quantum mechanics. did. Credit: Magnus Johansson Researchers from Linköping University, along with colleagues from Poland and Chile, have confirmed a theory suggesting a relationship…

Establishment of a general theory of metal-support interactions: Advances in catalytic reactions using AI
Credit: Pixabay/CC0 Public Domain How can artificial intelligence (AI) help accelerate scientific discoveries based on vast amounts of experimental data? A new study by Professor Li Weixue’s team at the University of Science and Technology of China (USTC) at the Chinese Academy of Sciences , we show how this can be achieved with heterogeneous catalysts. The results were published in…

Fluids thicken at the speed of light: new theory extends Einstein’s theory of relativity to real fluids
Credit: CC0 Public Domain Special relativity has many surprising and counterintuitive effects, the most famous of which are length reduction and time dilation. If an object moves with a velocity relative to an observer that is a non-negligible fraction of the speed of light, the length of the object in the direction of movement will appear to the observer to…

The discovery of a stable single-electron covalent bond between two carbon atoms substantiated a century-old theory.
Using an X-ray diffraction instrument to study sigma bonds. Photo courtesy of Yusuke Ishigaki A covalent bond is a bond in which two atoms join together by sharing a pair of electrons, forming the basic backbone of most organic compounds. In 1931, Nobel laureate Linus Pauling suggested that covalent bonds formed from a single unpaired electron could exist, but that…

Researchers deny the validity of the “set theory of everything” hypothesis
Credit: Pixabay/CC0 Public Domain Three new papers refute the ensemble theory of molecular complexity, which has been billed as a new “theory of everything.” First publicly proposed in 2017, assembly theory is a hypothesis about the measurable complexity of molecules that claims to characterize life, explain natural selection and evolution, and even redefine our understanding of time, matter, life, and…

New computational insights unlock the potential of photocatalysis using Marcus theory
Credit: ICIQ Dr. Albert Solé-Daura and Professor Feliu Maseras investigated the application of Marcus theory, traditionally used to model electron transfer, to estimate the free energy barrier underlying the energy transfer (EnT) process. These results confirm that Marcus theory can be effectively applied in combination with density functional theory (DFT) calculations to predict the EnT barrier height, facilitating computational studies…

Theoretical physicists develop method to model the central theory of quantum gravity in the lab
Illustration of the theory used to model quantum gravity: The lattice simulates a curved space-time. Near the boundary, the lattice becomes denser due to the curvature. Interacting electrical signals in the bulk (yellow, red, and blue lines) simulate the gravitational dynamics. The dynamics in the bulk and at the outer boundary correspond to each other. They are consistent with the…
