The ligand-to-metal charge transfer excited state of [Re(dmpe)3]2+

The ligand-to-metal charge transfer (LMCT) transitions of [Re(dmpe)3]2+ (dmpe = bis-1,2-(dimethylphosphino)ethane) were interrogated using UV/Vis absorbance spectroscopy, photoluminescence spectroscopy, and time-dependent density functional theory.

Understanding Terminal versus Bridging End-on N2 Coordination in Transition Metal Complexes

Here we elucidate the fundamental factors controlling the two binding modes and determining which is favored for a given metal–ligand system, using both quantitative density functional theory (DFT) and qualitative molecular orbital (MO) analyses.

Thermocleavage of Partial Side Chains in Polythiophenes Offers Appreciable Photovoltaic Efficiency and Significant Morphological Stability

We explore a series of regioregular polythiophenes having TCSs and hexyl side chains by varying the ratio of different side chains, from 0 mol % TCSs to 100 mol % TCSs at an increment of 20 mol %.

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.
