Viscosity and fragility of the supercooled liquids and melts from the Fe–Co–B–Si–Nb and Fe–Mo–P–C–B–Si glass-forming alloy systems
TL;DR: In this article, the dynamic viscosity of four Fe-based bulk metallic glass-forming alloys was investigated as a function of temperature in the supercooled liquid region, as well as above the melting point.
Journal ArticleDOI

TL;DR: In this paper, the authors developed a precursor approach toward the design of a TiN/Si3N4 nanocomposite with an activated carbon monolith as a support matrix forming a highly micro-/mesoporous component to be used as a Pt support for the catalytic hydrolysis of sodium borohydride (NaBH4) as a model reaction.
Journal ArticleDOI
Rapid Moisture-Responsive Silk Fibroin Actuators.
TL;DR: In this paper, the authors report the unique actuation characteristics of moisture-driven, fully reversible soft biopolymer films fabricated from Bombyx mori silk and demonstrate their ability to lift hundreds of milligrams of weight.
Journal ArticleDOI
Processing and characterization of polymer precursor derived silicon oxycarbide ceramic foams and compacts
TL;DR: In this article, the authors reported the fabrication of crack-free silicon oxycarbide compacts by cold compaction and pyrolysis route using polyvinyl alcohol (PVA) as a processing additive.
Journal ArticleDOI
Coarsening Induced Phase Transformation of Hafnia in Polymer-Derived Si-Hf-C-N-O Ceramics
TL;DR: In this article, a reverse phase transformation from tetragonal to monoclinic hafnia was studied in polymer-derived Si-Hf-C-N-O ceramics.
