Nano‐dispensing by electrospray for biotechnology
Biotechnology Journal, 2006 AbstractLiquid transport of minute amounts of biomaterials is of paramount importance in many biotechnological applications. One of the challenges is the transport of viscous liquids without heating. Electro hydro dynamic atomization or electrospray is a viable method for the controlled transport of nanoliter volume of viscous liquids as shown for ...

Surface tension effects on immersed electrosprays [PDF]
arXiv, 2012 Electrosprays are a powerful technique to generate charged micro/nanodroplets. In the last century, the technique received extensive study and successful applications, including a Nobel price in Chemistry. However, nowadays its use in microfluidic devices is still limited mainly due to a lack of knowledge of the phenomenon when the dispersing fluid is ...

Molecular Dynamics Simulation of Sympathetic Crystallization of Molecular Ions [PDF]
, 2003 It is shown that the translational degrees of freedom of a large variety of molecules, from light diatomic to heavy organic ones, can be cooled sympathetically and brought to rest (crystallized) in a linear Paul trap. The method relies on endowing the molecules with an appropriate positive charge, storage in a linear radiofrequency trap, and ...

Advanced Materials, EarlyView.An organic BTHG agent called OTBP with prominent crystallinity is developed. The resonant absorption at 433 nm and prominent crystallinity of OTBP enhance its BTHG efficiency when excited by a 1300 nm femtosecond laser. Tuning the size of OTBP nanocrystals based on Mie scattering theory successfully enables them to achieve high‐contrast muti‐organ ...

Understanding of droplet dynamics and deposition area in electrospraying process: Modeling and experimental Approaches [PDF]
arXiv, 2018 Electrospraying is a widely-used technique for generating microspherical droplets in biomedical and chemical applications and considered as an effective approach for the deposition on substrate. However, studies on effects of controllable parameters on deposition area of electrosprayed droplets have not been reported yet.

Levitated Spinning Graphene [PDF]
, 2010 A method is described for levitating micron-sized few layer graphene flakes in a quadrupole ion trap. Starting from a liquid suspension containing graphene, charged flakes are injected into the trap using the electrospray ionization technique and are probed optically.

Patterned Electrospray Fiber Structures [PDF]
International Nonwovens Journal, 2004 Electrospun fibers have useful filtration properties for chemical protective clothing and filter masks. Techniques for the patterned deposition of these fibers have been developed based on varying the conductivity of the target substrate. We are investigating multilayer arrangements of patterned fibers deposited in single layers, and onto air ...

A dual-trap system for the study of charged rotating graphene nanoplatelets in high vacuum [PDF]
, 2017 We discuss the design and implementation of a system for generating charged multilayer graphene nanoplatelets and introducing a nanoplatelet into a quadrupole ion trap in high vacuum. Levitation decouples the platelet from its environment and enables sensitive mechanical and magnetic measurements.
