Advances in Magnetohydrodynamic Molten Metal Jet Printing

Vader S., Vader Z., Vader S., Vader Z., Karampelas I.H., Furlani E.P., University at Buffalo (SUNY), US

At present, most metal 3D printing applications involve deposited metal powder sintering or melting under the influence of an external energy source such as a laser (e.g. Selective Laser Sintering (SLS) [1] and Direct Metal [...]

Plasmonic Nanocages as Photothermal Transducers for Nanobubble Cancer Therapy

Karampelas I.H., Liu K., Furlani E.P., University at Buffalo (SUNY), US

The ability to generate and control thermal energy with nanoscale resolution is finding increasing use in a variety of applications spanning the fields of nanoparticle synthesis, nanofabrication, bio-imaging and medical therapy [1, 2]. One of [...]

Analysis of Permeance vs. Support Porosity for Thin Film Composite Membranes

Karampelas I.H., Zhu L., Jia W., Yavari M., Lin H., Furlani E.P., University at Buffalo (SUNY), US

Membranes are an important technology for industrial gas separation and seawater desalination and emerging applications such as CO2 capture. The key to the steady growth of membrane applications is high performance thin film composite (TFC) [...]

Magnetohydrodynamic Liquid Metal Jet Printing

Vader S., Vader Z., Vader S., Vader Z., Karampelas I.H., Furlani E.P., SUNY-Buffalo, US

We present a novel method for drop-on-demand (DOD) printing of molten metal droplets into 3D objects. This method involves the use of heating to pre-melt a solid metal structure (e.g. rod) to form a reservoir [...]

Plasmonic Nanocages as Photothermal Transducers for Laser Induced Heating and Bubble Generation

Karampelas I.H., Alali F., Furlani E.P., SUNY-Buffalo, US

A series of new computational models is introduced to demonstrate several photonic and thermo-fluidic details of the photothermal process associated with nanosecond-pulsed, laser-heated gold nanocages. Such models can be used to simulate energy conversion within [...]

Open-Surface Microfluidics

Berthier J., Brakke K.A., Furlani E.P., Karampelas I.H., Delapierre G., CEA-LETI, FR

The developments of open-surface microfluidics (OSM) for biotechnology are recent, and motivated by the development of point-of-care (POC) and home-care systems. The advantages of capillary systems are (1) low cost due to easy and fast [...]

Numerical Analysis of Laser Induced Photothermal Effects using Colloidal Plasmonic Nanostructures

Karampelas I.H., Kim Y.H., Furlani E.P., University at Buffalo (SUNY), US

Colloidal plasmonic nanostructures are finding increasing use in a variety of applications that range from nanoparticle synthesis to bioimaging to medical therapy. In many such applications, a pulsed laser is used to heat plasmonic nanostructures [...]

Multiscale Biomechanical Modeling of the Human Eye

Karampelas I.H., Furlani E.P., Nunez A., Vizzeri G., State University of New York at Buffalo, US

The human eye is a complex organ consisting of multiple different tissues with varying mechanical properties and functionality. Hence, there are many aspects of the biomechanical behavior of the eye that are not understood. In [...]
