Mathematical model of a Hot Dry Rock system [PDF]

Geophysical Journal International, 1991
SUMMARY We derive a mathematical model which can be used to determine the evolution of the temperature in a Hot Dry Rock system. The essential feature of this approach is given by the fact that the solution is available by analytical methods. Therefore, long-term predictions of the evolution of the temperature as well as a detailed study concerning the

Mechanical Characteristics and Permeability Characteristics of Dry-Hot Rock Mass

Journal of Environmental and Public Health, 2023
As a rock mass with shallow burial, high temperature, and large-scale development, the study of its mechanical and seepage characteristics plays an important role in the efficient development of geothermal energy. With the development of geothermal energy in China, a breakthrough has been made in the exploration of dry-hot rocks, and the realization of

Impacts of Temperature and Pressure on the Thermophysical Properties of Granites

Energy Exploration & Exploitation
The thermophysical properties of rocks are identified as basic physical parameters for the exploitation and utilization of hot dry rock (HDR) geothermal resources. Given that reservoirs in a HDR system are subjected to a certain temperature and pressure,

Interfacial Failure and Self‐Healing in Solid‐State Batteries

Advanced Materials, EarlyView.
Dynamic interfacial self‐healing offers an adaptive route to mitigate coupled mechanical, chemical, and electrochemical degradation in solid‐state batteries. This review connects evolving interfacial failure mechanisms with physical‐flow, chemical‐restoration, stimuli‐responsive, and electric‐field‐assisted repair strategies, highlighting targeted self‐

Directing Near‐Perfect (001) Orientation in Wafer‐Scale BiOI Thin Films via Halide‐Mediated van der Waals Stacking

Advanced Materials, EarlyView.
Our work introduces a new framework that fundamentally changes how orientation in bismuth oxyhalide systems is approached. Comprehensive experiments, backed by theoretical models, reveal the pivotal role of halide anions to modify the van der Waals stacking energies required to direct orientation. Our method enables the fabrication of near perfect (001)

Hot Dry Rock Reservoir Engineering [PDF]

, 1988
The development of geothermal energy has been limited historically to the use of natural hot water and steam contained in what are referred to as hydrothermal geothermal reservoirs. However, as indicated by Roland Home elsewhere in these proceedings, probably less than 5% of the energy in a hydrothermal reservoir is contained in the extractable fluid ...

Probing the Energy Landscape of α‐Synuclein Amyloid Fibril Formation by Systematic K‐to‐Q Mutagenesis

Advanced Science, EarlyView.
We use lysine‐to‐glutamine mutations to study the effect of electrostatics on the kinetics and thermodynamics of alpha‐synuclein amyloid fibril formation. We find that mutational effects map on their structural context within fibrils and identify residues that modulate the energy landscape of alpha‐synuclein self‐assembly. Our work outlines a scalable,
