Design of a Simple and Rugged Soft Polydimethylsiloxane‐Carbon Nanotube‐Graphene‐Based Composite Sensor

open access: yesAdvanced Materials Technologies, EarlyView.
This research presents an easy to fabricate, low‐cost, flexible piezoresistive deformation sensor comprised of a carbon nanotube, few‐layer graphene, and polydimethylsiloxane composite. The sensor detects deformations and vibrations up to 600 Hz with 0.1% strain sensitivity from stiff and soft targets in dry and wet environments.

Development of quality assurance methods for epoxy graphite prepreg [PDF]

open access: yes
Quality assurance methods for graphite epoxy/prepregs were developed. Liquid chromatography, differential scanning calorimetry, and gel permeation chromatography were investigated. These methods were applied to a second prepreg system.

Adhesive for vacuum environments resists shock and vibration [PDF]

open access: yes, 1965
A mixture of a polyamide, an epoxy resin, and fine silica or glass microballoons provides an adhesive which is flexible, resistant to shock and vibration, and has improved heat-transfer ...

Dielectric Barrier Discharge Electrothermal Heating and Additive Manufacturing of Thermoset Parts

open access: yesAdvanced Materials Technologies, EarlyView.
3D printing of thermosets is difficult due to the low yield stress of most uncured resins. However, by locally heating resin using a non‐equilibrium plasma, layers can be partially cured and printing enabled. Plasma application to a liquid epoxy/carbon nanotube composite is observed to cause rapid surface heating and oxidation of the cured layers ...

Effects of hydrothermal exposure on a low-temperature cured epoxy [PDF]

open access: yes
Thermal mechanical analysis was employed to monitor the penetration temperature of a low-temperature epoxy resin. Both neat resin and E-glass composite samples were examined.

High‐Throughput Single‐Nanowire Optoelectronic Characterization Using Microfluidic Technology

open access: yesAdvanced Photonics Research, EarlyView.
An ultrathin microfluidic platform enables high‐throughput, in‐line single particle characterization of semiconductor nanowires. Using correlative spectroscopy and imaging, analysis at 240 nanowires per minute, uncovering previously hidden details about intra‐wire disorder and inter‐wire inhomogeneity, is achieved.
