Virtual Research Group Paper

In a joint effort with Prof. Marissa Tousley of Rose Hulman Institute of Technology, the HMNL reported results of the past several years of Virtual Research Group (VRG) pilots conducted at Rose Hulman and the New Jersey Governor's School for Engineering and Technology. These modules use a mix of real data from literature and simulated data to create a simulated experience of being in a research group that requires only minimal educational resources. The results showed that, among other findings, students found the VRG to be as enjoyable as conventional in-lab research experiences.

Early Career Materials Researcher Research Letter on FLaSk Dewetting Published

Professor Singer was recognized as an Early Career Materials Researcher by MRS Communications. The so-recognized letter discusses application of focused laser spike (FLaSk) thermocapillary dewetting as a tool for  measuring the properties of thin films. This research, led by former lab member Tianxing "Tim" Ma and conducted in collaboration with the lab of Zahra Fakhraai of UPenn Chemistry, demonstrated that FLaSk can uncover properties related to molecular weight and shear-induced ordering in nanoscale soft matter films.

HMNL Porous Composites Research Manuscript

In a joint effort with former HMNL Postdoc Prof. Molla Hasan (at UT-Permian Basin), HMNL PhD candidate Yogin Patel has published research on the porous materials formulation as the inside back cover of the latest issue of Advanced Materials Interfaces. High shear mixing of immiscible liquids, surfactant, and nanoparticles create a macropore-infused nanocomposite emulsion thermosets (MINET) with tunable surface behavior and pore size.

HMNL Mechanical Evaluation of Blended Electrospray Films Manuscript

In a joint effort with Prof. Assimina Pelegri here at Rutgers and Prof. Lin Lei at Chongqing Jiaotong University, HMNL PhD candidate Robert Green-Warren and former MS student, Luc Bontoux, led the investigation of the mechanical properties of thin films produced via self-limiting electrospray deposition (SLED). In this work, various polymers were composited, sprayed, and mechanically evaluated by nanoindentation.

HMNL Superhydrophobic Electrospray and Atomic Layer Deposition Coating Manuscript

In collaboration with Professor Mark Losego’s lab at Georgia Tech and former HMNL member Lin Lei at Chongqing Jiaotong University, HMNL member Catherine Nachtigal studied the application of atomic layer deposition (ALD) to methylcellulose nanowire forests deposited by self-limiting electrospray deposition (SLED). Applying a thin layer of ALD alumina made the nanowire forests superhydrophobic, while maintaining the conformal nature of both ALD and SLED.

HMNL Senior Design Light Modulator Manuscript

Published: 7/28/2021

The 2018-2019 HMNL Senior Design Team published their work on creating a thermocapillary dynamic spatial light modulator in Optics Letters. Here they showed for the first time that the thermocapillary dewetting could be used to make a dynamic optic. This method has the advantage of being able to operate with only a thin liquid layer over a high-quality reflective surface, meaning it could be applied to high power lasers.

HMNL Spray Templating Manuscript

Published: 10/04/2020

The HMNL and the Zahn and Zou Lab's recent work on self-limiting electrospray on thin film and dewetted templates has been published in Scientific Reports. The combination of laser dewetting and electrospray both brings together two of our lab's research thrusts and also is the first step to realizing the potential of developer-free lift-off. This work was funded by NSF award 1911518. You can read the article here.

Publication on Focused Laser Spike Dewetting

Published: 01/02/2019

HMNL's Tianxing Ma, Mike Nitzsche, Arielle Gamboa, and Valeria Saro-Cortes have published a manuscript that explores focused laser spike dewetting as a technique to create densely-packed monodisperse metal nanoparticles in localized areas in ambient conditions by manipulating capillary and thermocapillary dewetting on fluid-fluid interfaces. Read about it in ACS Applied Nano Materials.

Publication in the Journal of Micro- and Nano-manufacturing

Published: 11/14/2018

Our research work on 3D compatible sacrificial nanoimprint lithography (SNIL) to functionalize thermoplastic materials has been published in the Journal of Micro- and Nano-manufacturing. This work is a collaboration among HMNL, researchers at Yale, and participants of New Jersey Governor’s School for Engineering and Technology Program. To read this paper click here.
