Optical alignment device for two-photon microscopy

Biomedical Optics Express, 2018
Abstract Two-photon excitation fluorescence microscopy has revolutionized our understanding of brain structure and function through the high resolution and large penetration depth it offers. Investigating neural structures in vivo requires gaining optical access to the brain, which ...

The development of a high speed 3D 2-photon microscope for neuroscience

, 2010
The progress of neuroscience is limited by the instrumentation available to it for studying the brain. At present, there is a serious instrumentation gap between functional Magnetic Resonance Imaging (fMRI) of whole brains and the microscopic scale ...

Phase Evolution Kinetics in Additive‐Free 19.75% Organic Photovoltaics Empowered by Solvent Vapor Annealing

Advanced Functional Materials, EarlyView.
Solvent vapor annealing enables kinetic control of additive‐free morphology in organic solar cells. Selective plasticization of acceptor forms an optimal fibrillar network, boosting efficiency to 19.06% (binary) and 19.75% (ternary), with ultrafast exciton dissociation and reduced recombination.

Enhancement of Dielectric Breakdown Strength and Recoverable Energy Density in Three‐Dimensional Heterointerfaces on BaTiO3–PbZrO3–PbTiO3 Films via Room‐Temperature Nano‐Clustering

Advanced Functional Materials, EarlyView.
A room‐temperature aerosol deposition process yields multiphase nano‐clustered dielectric capacitors containing discrete BaTiO3, PbZrO3, and PbTiO3 crystals. This architecture creates three‐dimensional heterointerfaces that induce interfacial charge trapping and effectively inhibit breakdown propagation.

Advancing Tandem Organic Solar Cells With Ternary Acceptor Control for High‐Power Modules and Solar‐to‐Ammonia Conversion

Advanced Functional Materials, EarlyView.
Tandem organic solar cells with optimized ternary acceptor engineering achieved a power conversion efficiency of 15.53% and enabled a high‐voltage mini‐module (Voc 6.11 V). Integration into a bias‐free PV‐EC system further demonstrated efficient solar‐to‐ammonia (STA) conversion (97% Faradaic Efficiency, 4± 2% STA efficiency), highlighting scalable ...

Confocal microscopy

, 2011
Chapter focusing on confocal microscopy. A confocal microscope is one in which the illumination is confined to a small volume in the specimen, the detection is confined to the same volume and the image is built up by scanning this volume over the ...
