Fun with astrophysics

From Space.com: On Wednesday (Feb. 1) a comet that has not visited the Earth since the last ice age and the time of the Neanderthals will make its closest approach to our planet, or perigee.  …

A champion semiconductor, an "anti-laser" and two space missions are on our list, with the overall winner unveiled on 14 December

Lanthanide-doped upconversion nanoparticles (UCNPs) demonstrate many superior properties of broadly-tunable multicolor emission and long emission lifetimes. This makes them well-suited for many light-emission applications. Despite many advantages, the further progress and practical applications of UCNPs face significant challenges.

In recent years, many physicists worldwide have introduced atomic clocks, systems to measure the passing of time that are based on quantum states of atoms. These clocks can have numerous valuable applications, for instance in the development of satellite and navigation systems.

After astronomers ruled out all known light sources, there's still light leftover. Where is it coming from?

News headlines talk about a rare green comet appearing in the sky. The comet itself is rare, but green comets, not so much. What makes some comets appear green?

Recently, a research team led by Prof. Pan Jianwei and Prof. Zhao Bo from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS), used adiabatic magneto-association to create an ultracold gas of triatomic molecules with high phase-space density from a degenerate mixture of 23Na40K molecules and 40K atoms for the first time. This work was published in Science.

The exploration of mechanophores continues to expand the practical application of these molecules in materials science, organic synthesis, and pharmaceuticals due to their ability to change physically or chemically in response to force.

A team of experimentalists at the Max Planck Institute of Quantum Optics (MPQ) and theorists at the Chinese Academy of Sciences (CAS) has succeeded for the first time in populating and stabilizing a new type of molecule, so-called field-linked tetratomic molecules. These "supermolecules" are so fragile that they can only exist at ultracold temperatures. Their existence had long been suspected but has never been…

The article aims to answer the question "At what height is water like concrete?". It will also discuss the science behind what makes water so hard that it

Recently, a research team led by Prof. Ji Liang from Tianjin University, China, systematically introduced the research progress on the preparation of nitrate/nitrite by ammonia electro-oxidation reaction and proposed different strategies to enhance the electrocatalytic performance of the catalysts by modulating their composition and structure to inhibit the side reactions and electrode corrosion in the…

The protons and neutrons in a nucleus can form clusters analogous to atoms in a molecule, even in the nuclear ground state.

A novel air-laser-based standoff Raman spectrometer with high temporal and frequency resolutions has been constructed by Yao Fu and colleagues. The device can remotely probe chemical species in real time with high temporal resolution while monitoring the populations in their respective rovibronic levels in the frequency domain with sufficiently high spectral resolution.

Physicists in the MIT-Harvard Center for Ultracold Atoms developed a new approach to control the outcome of chemical reactions, using minute changes in a magnetic field to make subtle changes to the quantum mechanical wavefunction of the colliding particles during the chemical reaction.

Scientists from Columbia University have created kind of fifth state of matter that's dipolar, which opens the door for dozens of exotic matter applications

A team of physicists has produced pure trilobite molecules in rubidium over a wide range of frequencies and characterize their binding energies, lifetimes, and dipole moments.

The peculiar topological properties of some forms of matter have been researched for decades. Now, researchers at the Institute of Science and Technology Austria (ISTA) have discovered topological properties of simple diatomic molecules driven to rotation by laser pulses.
