We review marine heat flow data along the Nankai Trough and show that observations >30 km seaward of the deformation front are 20% below conductive predictions (129–94 mW m⁻²) but consistent with the global heat flow average for oceanic crust of the same age (16–28 Ma). Heat flow values ≤30...
[1] We report detailed thermal measurements undertaken during Integrated Ocean Drilling Program (IODP)
Expeditions 315 and 316 along the Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE) transect
offshore the Kii Peninsula, Japan. Geothermal objectives included determining thermophysical rock properties
of the cored material and characterizing the background thermal regime along this...
We examine variability observed in heat flow determinations collected on hot spot
swells. We find substantial scatter in heat flow at wavelengths of a few hundred kilometers
and less at both Hawaii and Reunion, where closely spaced data exist, and large variability
in the regional heat flow surveys at Cape...
The thermal structure of convergent margins provides information related to the tectonics, geodynamics,
metamorphism, and fluid flow of active plate boundaries. We report 176 heat flow measurements
made with a violin bow style probe across the Costa Rican margin at the Middle America Trench. The
probe measurements are collocated with...
DNA has a well-defined structural transition-the denaturation of its double-stranded form into two single strands-that strongly affects its thermal transport properties. We show that, according to a widely implemented model for DNA denaturation, one can engineer DNA 'heattronic' devices that have a rapidly increasing thermal conductance over a narrow temperature...
Using temperature gradients measured in 10 holes at 6 sites, we generate the first high fidelity heat flow measurements from Integrated Ocean Drilling Program drill holes across the northern and central Lesser Antilles arc and back arc Grenada basin. The implied heat flow, after correcting for bathymetry and sedimentation effects,...
Understanding groundwater conditions in the upland parts of volcanic island aquifers is critical for sustainable groundwater development in these resource-limited environments. Yet groundwater conditions in such settings are generally difficult to characterize because of sparse well drilling (high cost and/or limited access). Information needed for resource evaluation includes upland depth...
Fractal-like branching microchannel flow networks have been found to improve wall temperature uniformity and decrease both pressure drop and flow power compared to arrays of straight microchannels. The present study seeks to maximize the benefits of fractal-like branching channels by means of a gradient-based optimization algorithm. The algorithm identifies the...
The Laplace-Beltrami operator of a smooth Riemannian manifold is determined by the Riemannian metric. Conversely, the heat kernel constructed from the eigenvalues and eigenfunctions of the Laplace-Beltrami operator determines the Riemannian metric. This work proves the analogy on Euclidean polyhedral surfaces (triangle meshes), that the discrete heat kernel and the...
Cadmium sulfide (CdS) thin films are commonly used as buffer layers in thin film solar cells and can be produced by a number of solution and vacuum methods. We report the continuous solution deposition of CdS on fluorine-doped tin oxide coated glass substrates using Microreactor-Assisted Solution Deposition (MASD (TM)). A...
