It Is Good to Be Flexible: Energy Transport Facilitated by Conformational Fluctuations in Light-Harvesting Polymers

We investigate the mechanism of energy transfer between ruthenium(II) (Ru) and osmium(II) (Os) polypyridyl complexes affixed to a polyfluorene backbone (PF-RuOs) using a combination of time-resolved emission spectroscopy and coarse-grained molecular dynamics (CG MD).

Combination of Nitric Oxide Release and Surface Texture for Mitigating the Foreign Body Response

The tissue response to polyurethane (PU)-coated implants employing active and/or passive FBR mitigation techniques was evaluated over a 28 day study in a diabetic swine model.

Multidimensional time-of-flight spectroscopy

We present a multidimensional time-of-flight technique in which carrier transport is tracked with a second intervening laser pulse.

Amino-Deliquescence and Amino-Efflorescence of Methylammonium Lead Iodide

Here, using in situ spectroscopy and microscopy, we examine the thermodynamics and kinetics of the liquefaction and recrystallization of methylammonium lead iodide (MAPbI3) films with MA0 and find that the phenomena are best described as amino-deliquescence and amino-efflorescence, respectively.

Electrochemical quantification of accelerated FADGDH rates in aqueous nanodroplets

Here, we demonstrate rate enhancement of up to two orders of magnitude for enzymes trapped in submicrometer water nanodroplets suspended in 1,2-dichloroethane.

Mapping the plant proteome tools for surveying coordinating pathways

This review highlights recent advances in plant proteomics, with an emphasis on spatially and temporally resolved analysis of post-translational modifications and protein interactions.

Modernizing the Analytical Chemistry Laboratory: The Design and Implementation of a Modular Protein-Centered Course

Through the implementation of the five modules, students apply the fundaments of acid–base chemistry, statistics, quantification strategies, spectrophotometry, separations, and mass spectrometry, thus covering the material required in most undergraduate introductory analytical courses.

Photocatalytic Transfer Hydrogenation in Water: Insight into Mechanism and Catalyst Speciation

In this work, a photochemically induced aqueous ketone reduction catalyzed by [Cp*Ir(bpy)H][Cl] is reported and benchmarked to the competing hydrogen evolution reaction (HER).

Contributions of methionine to recognition of trimethyllysine in aromatic cage of PHD domains: implications of polarizability, hydrophobicity, and charge on binding

Our studies demonstrate that Met contributes to binding via dispersion forces, with about an equal contribution to binding Kme3 and tBuNle, indicating that electrostatic interactions do not play a role.

SHAPE Directed Discovery of New Functions in Large RNAs

By applying comprehensive structure probing to diverse problems, we and others are showing that control of biological function mediated by RNA structure is ubiquitous across prokaryotic and eukaryotic organisms.

A Generalized Potentiostat Adaptor for Multiplexed Electroanalysis

We present a versatile strategy for the development of flexible printed circuit (FPC) electrode arrays with accompanying multiplexing hardware to interface with single-channel potentiostats.

Atmospheric Deposition and Annual Flux of Legacy Perfluoroalkyl Substances and Replacement Perfluoroalkyl Ether Carboxylic Acids in Wilmington, NC, USA

This study shows the first direct evidence of PFECAs in wet and dry deposition. The data suggest that the particle-bound and gas-phase PFAS that may have undergone long-range transport can be incorporated into raindrops and removed rapidly.
