Unlocking Polymer Dynamics: A Path to Better Drug Delivery, Water Purification

A study explored how the diffusion of star-like and chain-like polymers depends on the pH and salt concentration of the solution.

UNC Study Uncovers Key Chemical Signal Behind Devastating Crop Disease

Researchers shed light on how Pseudomonas syringae, a common bacterial pathogen responsible for diseases in crops across the globe, uses a chemical signal to bolster its virulence and survival.

Study: Thickness and Phase of Organic Particles Affect Cloud Formation, Climate

At the heart of the research lies the phase state of organic aerosols, which can range from liquid to semisolid to glassy. This state determines their viscosity, a property that directly impacts their ability to nucleate ice.

Undergraduate researcher helps develop energy-efficient cellular isolation method
Diagram of special surface proteins, depicting 'catcher' and 'tag' proteins.

UNC-Chapel Hill Chemistry major Tarynn Neal designed her own research experience — and discovered an energy-efficient solution to an industrial-scale problem.

UNC Chemists Rethink How Electrocatalysts Work, Paving the Way for Improvements in Clean Energy

A study challenges long-standing assumptions in this field and opens new doors for designing more efficient electrocatalysts.

Researchers Develop Innovative Nitric Oxide Therapy for Skin Cancer

A team of researchers led by Dr. Mark Schoenfisch, Peter A. Ornstein Distinguished Professor at UNC-Chapel Hill, explores the potential of nitric oxide as a topical treatment for melanoma.

Researchers Integrate Recyclable Materials into Design of Semiconductors

In the quest to make organic electronics more environmentally friendly, researchers have developed a promising strategy for recycling organic semiconductors.

By Adding Single Carbon Atom to a Molecule, Researchers Spark New Horizons in Drug Design

The study introduces a new, simpler way to modify carboxylic acids—a common feature in many bioactive compounds and drugs.

Fluorescence shadow imaging of Hypsibius exemplaris reveals morphological differences between sucrose- and CaCl2-induced osmobiotes

Herein, an approach for discriminating between tardigrade morphological states is developed and utilized to compare sucrose- and CaCl2-induced tuns, using the model species Hypsibius exemplaris.

Architectural Editing of Polyesters and Polyurethanes via Palladium(II)-Catalyzed [3,3]-Sigmatropic Oxo-Rearrangements

Herein, we disclose a backbone rearrangement approach to tune the short-chain branching of polymers.

Reductive Dynamic and Static Excited State Quenching of a Homoleptic Ruthenium Complex Bearing Aldehyde Groups

A new homoleptic Ru polypyridyl complex bearing two aldehyde groups on each bipyridine ligand, [Ru(dab)3](PF6)2, where dab is 4,4′-dicarbaldehyde-2,2′-bipyridine, was synthesized, characterized, and utilized for iodide photo-oxidation studies.

Valence can control the nonexponential viscoelastic relaxation of multivalent reversible gels

Here, we propose a model where the relaxation of polymer gels in the dilute regime originates from elementary events in which the bonds connecting two neighboring cross-linkers all disconnect.
