This paper presented a microwave resonator-based dielectric metrology technique using new unified analytical model to extract complex permittivity of low-loss liquid materials. The main design drive the modified re-entrant cavity is confine electric field and therefore enhance interaction with material under test while maintaining high quality factor cavity. enables sensitivity when measuring l...

The unibody lab-on-a-chip (ULOC) concept entails a fast and affordable micro-prototyping system built around a single monolithic 3D printed element (unibody). A consumer-grade stereo lithography (SL) 3D printer can configure ULOCs with different forms of sample delivery, transport, handling and readout, while minimizing material costs and fabrication time. ULOC centralizes all complex fabricati...

This paper reports the fabrication of a biodegradable microfluidic device based on zein, a prolamin protein derived from corn. Micro-chambers and micro-channels features have been replicated on zein films using a stereo lithography master. Enclosed zein microfluidic devices are made by bonding the zein films with microfluidic features to glass substrates using a simple vapor-deposition method. ...

Synthesis of a homologous series of photo-polymerizable α,w-polytetrahydrofuranether-diacrylate (PTHF-DA) resins is described with characterization by NMR, GPC, DSC, soaking and rheometrical measurements. The curing speeds of the resins are determined under UV light exposure. Young's modulus and tensile strength of fully cured resins show flexible to soft material attributes dependent on the mo...

Construction equipment is typically massive and operated manually with minimal use of sensors or computers for measurement or control. Research in the Intelligent Systems and Structures Divisions at the National Institute of Standards and Technology has explored innovative ways to use sensors, computers, and lightweight, tensioned, cable machines for heavy manufacturing and construction tasks s...
