Researchers at Kanazawa University report in The Journal of Physical Chemistry Letters how to simulate 3D atomic force microscopy images of out-of-equilibrium systems involving biomolecules. The approach makes use of a celebrated equation from thermodynamics applicable to non-equilibrium situations.
Balances depict pentacene’s photostability
17 Jun 2022
A research group led by Professor Yoshio Teki of the Osaka Metropolitan University Graduate School of Engineering has succeeded in developing a new pentacene derivative that is more than 100 times more photostable than TIPS-pentacene, a photostable pentacene derivative. Additionally, the team has further clarified the ultrafast excited state dynamics in this system. In the pentacene moiety of this system, we were able to demonstrate that the transition from the excited singlet state to the excited triplet state occurs ultrafast in the time region of a 10-13 seconds. In purely organic materials without heavy atoms such as rare metals, such intersystem crossing usually occurs on time scales longer than 10-9 seconds. The empirical results of this study are expected to be applied as a method for stabilizing and developing light-unstable materials in the future.

In order to quickly detect the presence of the influenza A virus, researchers developed a fluorogenic probe that could bind to the promoter region. A fluorogenic probe uses tiny molecules called fluorophores that emit light when a specific target is present.

In a continuing effort to improve upon previous work, a research team at the Graduate School of Science, Osaka City University, have applied their recently developed Bayesian phase difference estimation quantum algorithm to perform full configuration interaction (full-CI) calculations of atoms and molecules without simulating the time evolution of the wave function conditional on an ancillary qubit. Superior to conventional methods in terms of parallel execution of quantum gates during quantum computing, this new algorithm is expected to be much easier to implement in actual quantum computers.

Researchers at Osaka City University create a quantum algorithm that removes spin contaminants while making chemical calculations on quantum computers. This allows for predictions of electronic and molecular behavior with degrees of precision not achievable with classical computers and paves the way for practical quantum computers to become a reality.

A new technique allows researchers to test how the deformation of tiny train track-like cell proteins affects their function. The findings could help clarify the roles of deformed “microtubules” in traumatic brain injuries and in neurological diseases like Parkinson’s.
