Review of artificial intelligence applications in geothermal energy extraction from hot dry rock

open access: yesDeep Underground Science and Engineering, EarlyView.
This paper systematically summarized the applications of artificial intelligence (AI) in hot dry rock (HDR) geothermal exploitation and discussed the limitations and opportunities. A novel intelligent HDR exploitation system was proposed to promote the development of HDR toward more efficiency, economy, and intelligence.

A photonic crystal cavity-optical fiber tip nanoparticle sensor for biomedical applications

open access: yes, 2012
We present a sensor capable of detecting solution-based nanoparticles using an optical fiber tip functionalized with a photonic crystal cavity. When sensor tips are retracted from a nanoparticle solution after being submerged, we find that a combination ...

Overview of geothermal resource exploration and development in North Africa

open access: yesDeep Underground Science and Engineering, EarlyView.
This article reviews geothermal exploration in North Africa, highlighting key activities, government policies, and exploration findings across Mauritania, Morocco, Algeria, Tunisia, Libya, and Egypt. The region's substantial geothermal potential, driven by tectonic activity, positions it to play a significant role in the global geothermal energy ...

Large-scale groundwater flow and sedimentary diagenesis in continental shelves influence marine chemical budgets

open access: yesNature Communications
The major ion chemistry of the ocean has been assumed to be controlled by river input, hydrothermal circulation at mid-ocean ridges, carbonate production, and low-temperature alteration of seafloor basalt, but marine chemical budgets remain difficult to ...

Feed‐Forward PID‐Based Cooperative Control Strategy for Air Mass Flow and Pressure in PEMFC Systems

open access: yesEnergy Science &Engineering, EarlyView.
This manuscript presents an 86 kW proton exchange membrane fuel cell (PEMFC) with a feed‐forward PID control strategy, tested in an engine environment. The air mass flow and pressure changes are analyzed across three stages: loading, de‐loading, and wide range of sudden load drop. Experimental results demonstrate the control strategy's effectiveness of

Magneto‐Hydrothermal and Entropy Analysis of Double‐Diffusive Convection in a Nano‐Encapsulated PCM‐Suspended Elliptical Pipes Thermal Storage Tank: Impact of Exothermic Reaction

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT PCMs store thermal energy during phase transitions without temperature changes, making them valuable for various thermal applications. When direct PCM use isn't practical, researchers have developed encapsulation methods as an alternative approach.

Chemical environments of submarine hydrothermal systems [PDF]

open access: yes
Perhaps because black-smoker chimneys make tremendous subjects for magazine covers, the proposal that submarine hydrothermal systems were involved in the origin of life has caused many investigators to focus on the eye-catching hydrothermal vents.
