Isothermal self-assembly of multicomponent and evolutive DNA nanostructures
Multiple complementary DNA strands can be thermally annealed into desired entities to engineer DNA nanostructures. In a new study now published in Nature Nanotechnology, Caroline Rossi-Gendron and a team of researchers in chemistry, materials science.....»»
Small-molecule autocatalysis may have paved the way for the emergence of evolution by natural selection
The discipline of systems chemistry deals with the analysis and synthesis of various autocatalytic systems and is therefore closely related to the study of the origin of life, since it investigates systems that can be considered as a transition betwe.....»»
Breakthrough polymer research promises to revolutionize recycling
A team of researchers led by Brent Sumerlin, the George B. Butler Professor in the University of Florida Department of Chemistry, has made a breakthrough with the potential to transform how we recycle plastics. Their innovative approach to working wi.....»»
J. Robert Oppenheimer"s early work revolutionized the field of quantum chemistry, and his theory is still used today
The release of the film "Oppenheimer," in July 2023, has renewed interest in the enigmatic scientist J. Robert Oppenheimer's life. While Oppenheimer will always be recognized as the father of the atomic bomb, his early contributions to quantum mechan.....»»
Chemists need to consider the effects of chemistry beyond the lab to combat environmental crises, say researchers
In a comment in Nature Reviews Chemistry, Ph.D. student Hannah Flerlage and associate professor Chris Slootweg of the University of Amsterdam's Van 't Hoff Institute for Molecular Sciences argue that modern day chemists need to broaden their horizons.....»»
In the treetops: Ecologist studies canopy soil abundance, chemistry
When we think of soil, most of us think of dirt on the ground. But a surprising amount of the planet's soil thrives in the treetops of old-growth forests, high above terra firma......»»
Scientists develop novel method to synthesize azide compounds for wider industrial applications
Azide compounds play a pivotal role for subsequent synthesis of organonitrogens such as amines and triazoles that are essential compounds in organic and materials chemistry. Triazoles that can be synthesized by the 'click' reaction have attracted att.....»»
Nanorings: New building blocks for chemistry
Sandwich compounds are special chemical compounds used as basic building blocks in organometallic chemistry. So far, their structure has always been linear......»»
Old mattresses made new: Simple chemistry can recycle polyurethane
It created something of a stir back in 2022, when researchers from Aarhus University announced a new and inexpensive way of breaking down polyurethane (PU) plastic into its original components, which can then be recycled into new PU material instead.....»»
Seeing light elements in a grain boundary: Revealing material properties down to the atomic scale
To develop advanced materials, a deep understanding of their underlying microstructure and chemistry is necessary. Knowing how defects influence the interplay between microstructure and chemical composition is crucial, as they are the entry gate for.....»»
"Andreev chemistry" on a nanowire: Researchers generate superconducting pair states separated by grown barriers
Researchers at the University of Basel and Lund University have generated superconducting pair states of electrons on several segments of a nanowire, separated by grown barriers. Depending on the height of the barriers, these pair states can be coupl.....»»
Scientists unveil synergistic method for non-canonical amino acid synthesis
New chemistry, new enzymology. With a new method that merges the best of two worlds—the unique and complementary activities of enzymes and small-molecule photochemistry—researchers at UC Santa Barbara have opened the door to new catalytic reactio.....»»
Scientists develop hydrous liquid metals for use in rhythmic bionic tissues

Towards silver cluster-assembled materials for environmental monitoring
In recent years, there has been a growing interest in using silver nanoclusters (Ag NCs), nanoscale silver particles composed of tens to hundreds of atoms, across various fields like material science, chemistry, and biology. Ag NCs typically have siz.....»»
New DNA identification approach could improve monitoring for chronic diseases
Investigators led by Shana Kelley, Ph.D., the Neena B. Schwartz Professor of Chemistry, Biomedical Engineering, and of Biochemistry and Molecular Genetics, have developed a novel approach for identifying sequences of artificial DNA with differing lev.....»»
Enterprises should layer-up security to avoid legal repercussions
The role of CISO these days requires a strong moral compass: You have to be the one speaking up for the protection of customer data and be ready to handle uncomfortable situations such as pressure to downplay an actual breach. Do we admit that a data.....»»
Journal editors weigh in on AI in science publishing
Last week, the Journal of Biological Chemistry (JBC) published an editorial to define appropriate and inappropriate uses of artificial intelligence technology in the "preparation and review of manuscripts being considered for publication.".....»»
Researchers describe "nanoclays," an innovative addition to tools for chemists
