ChemQuests: A Curated Chemistry Question-Answer Database Extracted from ChemRxiv papers
arXiv:2505.05232v3 Announce Type: replace Abstract: The rapid expansion of chemistry literature poses significant challenges for researchers seeking to efficiently access domain-specific knowledge. To support advancements in chemistry-focused natural language processing (NLP), we present ChemQuests, a curated dataset of 952 high-quality question-answer (QA) pairs derived from 155 ChemRxiv \cite{chemrxivWebsite} papers across 17 subfields of chemistry. Each QA pair is explicitly linked to its...
Tiny X-ray telescope could unlock the Moon's hidden chemistry
Tiny X-ray telescope could unlock the Moon's hidden chemistry A tiny new X-ray telescope could unlock the Moon’s hidden chemistry and finally reveal how our nearest neighbor evolved. - Date: - June 6, 2026 - Source: - Tokyo Metropolitan University - Summary: - A lightweight new X-ray telescope could finally give scientists something they’ve never had before: a complete chemical map of the Moon.
Whiskey chemistry propels microscopic machines through liquid
Whiskey chemistry propels microscopic machines through liquid Sadie Harley Scientific Editor Robert Egan Associate Editor Whisky-inspired chemicals could help power a new generation of microscopic machines, according to researchers who have discovered a way to make tiny particles "swim" through liquid using compounds linked to the production of Scotland's national drink. Scientists drew inspiration from the chemistry behind whisky's distinctive flavors and aromas, which are shaped by...
NASA's Webb detects methane and strange chemistry on interstellar comet 3I/ATLAS
NASA's Webb detects methane and strange chemistry on interstellar comet 3I/ATLAS - Date: - June 4, 2026 - Source: - NASA - Summary: - NASA's James Webb Space Telescope has uncovered unusual chemistry in interstellar comet 3I/ATLAS, including the first direct detection of methane on a visitor from another star system. The comet also contains exceptionally high levels of carbon dioxide, making it unlike most comets born in our solar system. Scientists believe the methane was hidden beneath the...
Programmable chemistry unlocks drugs only in target cells, aiming to cut side effects
Programmable chemistry unlocks drugs only in target cells, aiming to cut side effects Gaby Clark Scientific Editor Robert Egan Associate Editor Potent drugs like chemotherapy can be life-saving, but often with life-threatening side effects. Notably, they can be indiscriminate, killing both cancer cells and healthy cells in one swoop. Increasing a drug's on-target efficiency can reduce side effects and enable healthier outcomes for patients.
A natural chemistry laboratory in protostar shock waves
A natural chemistry laboratory in protostar shock waves Lisa Lock Scientific Editor Andrew Zinin Lead Editor Life exists because elements combine to form complex organic molecules. Astrochemistry studies this process, trying to understand how nature creates carbon-based molecules critical for life. One source for these types of molecules is the outflows emitted by protostars.
GM eyes new battery chemistry to grow AI data center, energy storage business
General Motors is expanding efforts to capitalize on the expected growth of energy storage and data centers by promoting different battery cell chemistries, while also offering more support for its electric vehicle owners to combat higher energy costs. The Detroit automaker detailed plans Tuesday to increase its vehicle-to-grid capabilities — in which a vehicle can provide energy to the electric grid — for its EV customers and develop next-generation sodium-ion batteries that GM's battery...
How tuning atomic order and surface chemistry can shape MXenes
How tuning atomic order and surface chemistry can shape MXenes Sadie Harley Scientific Editor Robert Egan Associate Editor Scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory are helping show what it means to design a material almost atom-by-atom. In two publications, scientists show they can carefully choose the types of atoms in a material, where those atoms sit and what is attached to the surfaces of its atom-thin layers. That level of control lets them tailor...
Cosmic bombardment may have opened Earth's crust for prebiotic chemistry
Cosmic bombardment may have opened Earth's crust for prebiotic chemistry Gaby Clark Scientific Editor Robert Egan Associate Editor Asteroids and planetesimals regularly bombarded Earth between about 4.6 billion and 3.5 billion years ago, during the Hadean and Archean eons. Because few rocks today are more than 4 billion years old, our understanding of the planet's environment during that time is limited. However, samples from the moon and its cratered surface hint at the period's rate of...
MARUT: An Exascale-Ready, GPU-Accelerated High-Order CFD Framework with AMR for High-Speed Flows and Finite-Rate Chemistry
arXiv:2605.26388v3 Announce Type: replace Abstract: We present MARUT, a scalable multi-GPU computational fluid dynamics (CFD) framework designed for high-fidelity simulations of compressible flows spanning subsonic to hypersonic regimes, including chemically reacting nonequilibrium flows with finite-rate chemistry and adaptive mesh refinement (AMR). The framework addresses a central challenge in contemporary scientific computing: the development of numerically accurate and computationally...
