Size Characterisation Method and Detection Enhancement of Plasmonic Nanoparticles in a Pump–Probe System

Applied Sciences, 2017
The optical resonance of metal nanoparticles can be used to enhance the generation and detection of their main vibrational mode. In this work, we show that this method allows the accurate characterisation of the particle’s size because the vibrational ...

When Poor Exciton Dissociation Limits Photocurrents in Organic Solar Cells: Why Low Offset Non‐Fullerene Acceptor Blends Can't Be Efficient

Advanced Materials, EarlyView.
The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...

Analysis of the high-resolution spectra of methyl fluoride in the region of 2400-2800 cm-1

Известия Томского политехнического университета: Инжиниринг георесурсов, 2019
The relevance of the current research is caused by the need of knowledge about the high resolution ro-vibrational spectra of the symmetric top molecules, which is an essential doorway towards the understanding of the fundamental physical properties of ...

Neutron Diffraction on Piezoelectric Vibrating Resonators [PDF]

Nature, 1968
THIS communication explains some experimental results published by Parkinson and Moyer1,2* by proving that the wave amplitude associated with neutrons reflected from a lattice of vibrating piezoelectric resonators corresponds to the amplitude of a frequency modulated wave3,4.

Laser‐Assisted Phase Engineering of 2D MoS2 for Efficient Solution‐Processed Electronics

Advanced Materials, EarlyView.
Here, local laser‐assisted phase transition from solution‐processed phase‐pure 1T′ to 2H MoS2 is shown to critically depend on the irradiation atmosphere. While processing in air leads to damaged insulating regions, inert conditions yield semiconducting 2H domains, enabling direct field‐effect transistor patterning with optimized lateral 1T′‐2H MoS2 ...

Theoretical and quantum mechanical deconstruction of vibrational energy transfer pathways modified by collective vibrational strong coupling

Nature Communications
Recent experiments have demonstrated that vibrational strong coupling (VSC) between molecular vibrations and the optical cavity field can modify vibrational energy transfer (VET) processes in molecular systems.

Trions as Fundamental Species in Chemically Doped Polymer Semiconductors

Advanced Materials, EarlyView.
This work shows that exciton–charge carrier coupling in doped polymer semiconductors gives rise to multi‐particle states, including trions—quasiparticles consisting of two holes and one electron under p‐doping—and bound exciton‐hole pairs, as identified through spectroscopic and theoretical analysis.

Excited State Structural Evolution of a GFP Single-Site Mutant Tracked by Tunable Femtosecond-Stimulated Raman Spectroscopy

Molecules, 2018
Tracking vibrational motions during a photochemical or photophysical process has gained momentum, due to its sensitivity to the progression of reaction and change of environment.
