Role and Effect of Meso-Structuring Surfactants on Properties and Formation Mechanism of Microfluidic-Enabled Mesoporous Silica Microspheres

We have shown in a previous work that the combination of the emulsion solvent evaporation technique and droplet-based microfluidics allows for the synthesis of well-defined monodisperse mesoporous silica microcapsules (hollow microspheres), whose…

Quantum diamond magnetometry for high pressure sensing

Diamond anvil cell (DAC) technology is widely used to study materials under high pressure. These materials can exhibit exotic phases of matter such as superconductivity with exceptionally high critical temperatures. The main difficulty with using…

First Experimental Evidence of Anti-Stokes Laser-Induced Fluorescence Emission in Microdroplets and Microfluidic Systems Driven by Low Thermal Conductivity of Fluorocarbon Carrier Oil

With the advent of many optofluidic and droplet microfluidic applications using laserinduced fluorescence (LIF), the need for a better understanding of the heating effect induced by pump laser excitation sources and good monitoring of temperature…

Quadratic nonlinearities of gold nanoprisms in solution: the role of corner sharpness

The size and shape (nanospheres, nanorods, nanostars…) of metallic nanoparticles significantly affect their physical and chemical properties. Among these nanostructures, acentric objects are expected to display high quadratic nonlinear responses,…

Very Accurate Flexible pH Microsensor Based on Nanoporous Titanium Nitride Material for In Vivo Application

Recently, the need for a real-time and less invasive solution to replace in-laboratory blood analysis by analyzing in situ biological fluids (sweat, saliva, tear, urine, and interstitial fluid) has grown alongside the development of microfabrication…

Enabling quantum sensing under extreme pressure: Nitrogen-vacancy magnetometry up to 130 GPa

Engineering a layer of nitrogen-vacancy (NV) centers on the tip of a diamond anvil creates a multipurpose quantum sensor array for high-pressure measurements, especially for probing the magnetic and superconducting properties of materials. Expanding…
