Microchannel fabrication

In this project, we have studied a new microchannel fabrication technique based on the idea of the transference of a thin layer of Si3N4 on top of grooves to form channels. In order to do so, we have created two different wafers. The first of them was a si ...

A 3D printed beam splitter for polar neutral molecules

Andreas Osterwalder, Sean Dennis Steven Gordon

We describe a beam splitter for polar neutral molecules. An electrostatic hexapole initially confines and guides a supersonic expansion of ammonia, and it then smoothly transforms into two bent quadrupole guides, thus splitting the molecular beam in two co ...

Defect Healing and Charge Transfer-Mediated Valley Polarization in MoS2/MoSe2/MoS2 heterostructures

Andras Kis, Dumitru Dumcenco, Yen-Cheng Kung, Alessandro Surrente

Monolayer transition metal dichalcogenides (TMDCs) grown by chemical vapor deposition (CVD) are plagued by a significantly lower optical quality compared to exfoliated TMDCs. In this work, we show that the optical quality of CVD-grown MoSe2 is completely r ...

Flexible fabric-based wearable solid-state supercapacitor

Jürgen Brugger, Xiao Sheng Zhang, Bo Meng

In this paper, we present a novel wearable flexible supercapacitor with the conductive carbon-nanotube (CNT)/fabric electrode and PVA/H3PO4 solid-state electrolyte, which is cost-effective and can be easily mass produced. Two kinds of fabric as the electro ...

Large-Area Low-Cost Plasmonic Perfect Absorber Chemical Sensor Fabricated by Laser Interference Lithography

Andreas Tittl

We employ laser interference lithography as a reliable and low-cost fabrication method to create nanowire and nanosquare arrays in photopolymers for manufacturing plasmonic perfect absorber sensors over homogeneous areas as large as 5.7 cm(2). Subsequently ...

Multi-code analysis of scrape-off layer filament dynamics in MAST

Paolo Ricci, Fabio Riva

Four numerical codes are employed to investigate the dynamics of scrape-off layer filaments in tokamak relevant conditions. Experimental measurements were taken in the MAST device using visual camera imaging, which allows the evaluation of the perpendicula ...

Fabrication of slender elastic shells by the coating of curved surfaces

François Gallaire, Pedro Miguel Nunes Pereira de Almeida Reis, Gioele Mariano Nicolò Balestra, Pierre-Thomas Paul Brun

Various manufacturing techniques exist to produce double-curvature shells, including injection, rotational and blow molding, as well as dip coating. However, these industrial processes are typically geared for mass production and are not directly applicabl ...

Fabrication-Aware Design of Timber Folded Plate Shells with Double Through Tenon Joints

Yves Weinand, Christopher Werner Matthias Robeller

Integral attachment, the joining of parts through their form rather than additional connectors or adhesives, is a common technique in many industry sectors. Following a renaissance of integral joints for timber frame structures, recent research investigate ...

Screening method for the onset of bonding of molten polyamide resin layers to continuous fiber reinforced laminate sheets

Martyn Douglas Wakeman

Thermoplastic polymer composites (TPC) with multiple fabric layers of continuous fiber reinforcement are laminate sheets designed to be thermally stamped and overmolded leading to low cycle times and thus high volume composite parts. Injection over-molding ...
