Understanding of Face-On Crystallites Transitioning to Edge-On Crystallites in Thiophene-Based Conjugated Polymers

We designed and synthesized a random copolymer (RP-3T) by inserting unsubstituted terthiophenes into regioregular poly(3-hexylthiophene)s.

Interfacial Electron Transfer through Ultrathin ALD TiOx Layers: A Comparative Study of TiO2/TiOx and SnO2/TiOx Core/Shell Nanocrystals

Mesoporous anatase TiO2, mixed anatase/brookite TiO2, and rutile-type SnO2 nanocrystalline films were coated with ultrathin (<5 nm) TiOx by the atomic layer deposition (ALD) of tetrakisdimethylamidotitanium(IV) and water at 150 °C to fabricate SnO2/TiOx and TiO2/TiOx core/shell materials.

Direct Mapping of Higher-Order RNA Interactions by SHAPE-JuMP

Here, we present SHAPE-JuMP (selective 2′-hydroxyl acylation analyzed by primer extension and juxtaposed merged pairs) to interrogate through-space RNA tertiary interactions.

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.
