Interfacial Chemical Vapor Deposition of Wrinkle-Free Bilayer Graphene on Dielectric Substrates

Wrinkles invariably form during graphene growth and post-growth transfer, limiting graphene films' large-scale uniformity for electronic applications. We report a transfer-free synthesis route for highly-uniform bilayer graphene directly on …

Graphene-mediated stabilization of surface facets on metal substrates

After Chemical Vapor Deposition (CVD), faceted structures are routinely observed on a variety of metal catalyst surfaces in the graphene-covered regions. In spite of having its bare surface flattened through high diffusivity and surface pre-melting …

Digital metal printing by electrohydrodynamic ejection and in-flight melting of microparticles

Metal additive manufacturing (AM) will impact many industries, including those producting of advanced structural, propulsion, electronic, and thermal systems. Many established metal AM processes involve layer-by-layer deposition and selective binding …

Crowd-sourced data and analysis tools for advancing the chemical vapor deposition of graphene implications for manufacturing

Industrial production of graphene by chemical vapor deposition (CVD) requires more than the ability to synthesize large domain, high-quality graphene in a lab reactor. The integration of graphene in the fabrication process of electronic devices …

Elastic modulus scaling in graphene-metal composite nanoribbons

This study addresses the synthesis and mechanical behavior of graphene-metal composites comprising palladium (Pd) nanoribbons wrapped with graphene. Coating Pd nanoribbons with graphene by chemical vapor deposition (CVD) considerably increases their …

Digital texture voxels for stretchable morphing skin applications

The skin of the cephalopod is a 3D display, where the papillae muscles control the protrusion of each voxel by several millimeters out of the skin plane, create hierarchical textures, and collectively change the overall skin pattern in a fraction of …

Gilding with graphene: rapid chemical vapor deposition synthesis of graphene on thin metal leaves

Gilding is the ancient process of coating intricate artifacts with precious metals. Fascinating Egyptian and Chinese sculptures, coated with

Tailoring the mechanical properties of 2D materials and heterostructures

The mechanical behavior of high quality two-dimensional (2D) crystals offers exciting opportunities for new material design, such as the combination of extremely high in-plane stiffness and bending flexibility, compared to existing three-dimensional …

Performance comparison of jet pumps with round and sharp edge of small opening in oscillatory flow

Owing to the capability to induce a time-averaged pressure drop in oscillatory flow, a jet pump has been used to suppress the Gedeon streaming in a looped thermoacoustic engine. The suppression capacity originates from the asymmetric pressure drop …

Time-averaged pressure drop induced by a jet pump in oscillatory flow

Gedeon streaming is known to considerably deteriorate the thermal efficiency of a traveling-wave thermoacoustic engine with looped configuration. The time-average pressure drop induced by a jet pump can efficiently suppress the Gedeon streaming. In …
