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.

Factors that Impact Photochemical Cage Escape Yields

Herein, state-of-the-art research on light-induced electron transfer and cage escape that has appeared since the seminal 1972 review by J. P. Lorand entitled “The Cage Effect” is reviewed.

Nanogalvanic Cells Release Highly Reactive Electrons in Tumors to Effectively Eliminate Tumors

Here, this work presents galvanic cell nanomaterials that can directly release highly reactive electrons in tumors without external irradiation or photosensitizers.

Stochastic distinguishability of Markovian trajectories

This work provides a general formula that decomposes the Kullback-Leibler divergence in space and time for any Markov processes, arbitrarily far from equilibrium or steady state.

Supramolecular Templation of Entanglements and Their Spectroscopic Detection in Polymer Elastomers

Here, we use supramolecular templates based on phenanthroline-copper(I) complexes to install into poly(methoxyethyl acrylate) elastomer-trapped entanglements whose topology is programmed by the complex geometry.

Stereoselective Polymerization of 3,6-Disubstituted N-Vinylcarbazoles

Here, we report the stereoselective cationic polymerization of a series of 3,6-disubtituted N-vinylcarbazole derivatives using a chiral scandium-bis(oxazoline) Lewis acid catalyst.

External liquid calibration method for iodide chemical ionization mass spectrometry enables quantification of gas-phase per- and polyfluoroalkyl substances (PFAS) dynamics in indoor air

Herein, we present a direct liquid injection method for external calibration, providing detection limits of 0.19–3.1 pptv for 3 s averaging and 0.02–0.44 pptv for 120 s averaging, with the exception of E2, which had detection limits of 1700 and 220 pptv for 3- and 120 s averaging, respectively.

Protecting Proteins from Desiccation Stress Using Molecular Glasses and Gels

Amorphous glassy media composed of small molecular solutes or protein gels present general strategies for protecting against drying. We review these strategies and the proposed molecular mechanisms to explain protein protection in a vitreous matrix under conditions of low hydration.

Real-Time TDDFT for Nonequilibrium Electron Dynamics

In the invited Perspective article for the Journal of the American Chemical Society, members of the Kanai research group discuss...
