Advanced Science, EarlyView.Two microwave‐assisted synthetic methods, specifically a one‐pot and a seeded‐growth approach, are developed within a hydroalcoholic solution for the growth of single‐phase ternary WxTi1‐xO2 and heterostructured TiO2‐WO3‐x colloidal nanocrystals. Both types of nanocrystals show significant photocatalytic activity for 4‐methoxybenzyl alcohol oxidation ...

Four wave mixing spectroscopy of quantum dot molecules
, 2007 We study theoretically the nonlinear four wave mixing (FWM) response of an ensemble of coupled pairs of quantum dots (quantum dot molecules). We discuss the shape of the FWM echo signal depending on the parameters of the ensemble: the statistics of ...

Ultrafast Nonlinear Dynamics of Indium Tin Oxide Nanocrystals Probed via Fieldoscopy
Advanced Science, EarlyView.The ultrafast nonlinear dynamics of indium tin oxide nanocrystals excited with 1 MHz, 10 fs pulses, at their localized surface plasmon frequency, and near their epsilon‐near‐zero wavelength is probed via fieldoscopy. The study demonstrates fluence‐dependent switching behavior, advancing the understanding of high‐speed optical modulation in plasmonic ...

Perspective: Hollow Core Optical Fibres for Ultraviolet and Visible Wavelengths
Advanced Science, EarlyView.Hollow core optical fibres bypass material constraints that limit optical fibres at ultraviolet and visible wavelengths. However, their challenging fabrication has limited their development, and significant gains in performance remain possible. In this perspective we outline approaches to enable the next generation of fibres for shorter wavelengths ...

Ultrashort time to echo magnetic resonance techniques for the musculoskeletal system [PDF]
Quantitative Imaging in Medicine and Surgery, 2016 Magnetic resonance (MR) imaging has been widely implemented as a non-invasive modality to investigate musculoskeletal (MSK) tissue disease, injury, and pathology. Advancements in MR sequences provide not only enhanced morphologic contrast for soft tissues, but also quantitative biochemical evaluation.

Advanced Science, EarlyView.This study investigates the impact of various post‐processing methods (filtration, sonication, dialysis, and heating) on lipid nanoparticles produced using microfluidics. The nanoparticles are designed for efficient delivery of miRNA into cells. The work highlights how processing conditions influence nanoparticle stability and quality, providing ...

Computer Methods in Biomechanics and Biomedical Engineering: Imaging & VisualizationFascia is a connective tissue that influences movement and may play roles in muscle force transmission, pain sensation, and lymphatic function. To date, 3D imaging of fascia using MRI has not been achieved due to short T2* times of collagen-rich fascia ...
