Journal ArticleDOI

Moving beyond molecules: Patterning solid-state features via dip-pen nanolithography with sol-based inks

TL;DR: A new dip-pen nanolithography (DPN)-based method for the direct patterning of organic/inorganic composite nanostructures on silicon and oxidized silicon substrates is described, opening up the opportunity for using DPN to deposit solid-state materials rather than simple organic molecules onto surfaces with the resolution of an AFM without the need for a driving force other than chemisorption.
Journal ArticleDOI

Thermal Scanning at the Cellular Level by an Optically Trapped Upconverting Fluorescent Particle.

TL;DR: 3D optical manipulation of a thermal-sensing upconverting particle allows for the determination of the extension of the thermal gradient created in the surroundings of a plasmonic-mediated photothermal-treated HeLa cancer cell.
Journal ArticleDOI

Multishelled Nix Co3-x O4 Hollow Microspheres Derived from Bimetal-Organic Frameworks as Anode Materials for High-Performance Lithium-Ion Batteries.

TL;DR: A facile and cost-efficient strategy is developed to scalably fabricate binary metal oxides with complex hollow interior structures and tunable compositions for progressive lithium-ion batteries.
Journal ArticleDOI

A twisted-intramolecular-charge-transfer (TICT) based ratiometric fluorescent thermometer with a mega-Stokes shift and a positive temperature coefficient

TL;DR: The fluorescence intensity of N,N-dimethyl-4-((2-methylquinolin-6-yl)ethynyl)aniline exhibits an unusual intensification with increasing temperature, by activating more vibrational bands and leading to stronger TICT emissions upon heating in dimethyl sulfoxide.
Journal ArticleDOI

Quantitative Design of Bright Fluorophores and AIEgens by the Accurate Prediction of Twisted Intramolecular Charge Transfer (TICT)

TL;DR: Based on a comprehensive comparison of various representative exchange-correlation functionals and solvent formalisms, a reliable and generalizable computational approach is established for modeling TICT formations of popular organic fluorophores with time-dependent density functional theory (TD-DFT).
