Hot dry rock fracture propagation and reservoir characterization [PDF]

open access: yes, 1988
North America's largest hydraulic fracturing opeations have been conducted at Fenton hill, New mexico to creae hot dry rock geothermal reservoirs. Microearthquakes induced by these fracturing operations were measured with geophones.

Low‐Temperature in Situ Upgrading of Ultra‐Deep Heavy Oil Using Ni–Ce/MOF–OTf Superacid Catalysts to Enhance Energy Utilization and Sustainability

open access: yesEcoEnergy, EarlyView.
A triflate‐functionalized Ni–Ce/MOF–OTf superacid enables low‐temperature (∼140°C) in situ upgrading of ultra‐deep heavy oil. It reduces viscosity by 92.11% in 12 h, maintains activity over cycles, and delivers 90.25% recovery with a lower carbon footprint by selective bond cleavage. ABSTRACT Ultra‐deep heavy oil is an important unconventional resource,

Diverse hypolithic refuge communities in the McMurdo Dry Valleys [PDF]

open access: yes, 2010
Hyper-arid deserts present extreme challenges to life. The environmental buffering provided by quartz and other translucent rocks allows hypolithic microbial communities to develop on sub-soil surfaces of such rocks.

Anode Materials Requirements for Potassium Ion Batteries: Challenges and Future Possibilities

open access: yesEcoEnergy, EarlyView.
This work identifies a critical scale‐up gap between laboratory battery research and industrial targets, driven by low active‐mass loadings and the omission of full‐cell metrics. We outline concrete strategies to bridge this divide, shifting focus toward high‐loading electrodes (> 3 mg cm−2) to ensure practical commercial viability of potassium ion ...

Nanocubes and Cuboctahedra: Entropic Stabilization Versus Thermal Segregation in Rock Salt‐ and Spinel‐Type Multinary Oxides from Spray‐Flame Synthesis

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Spray‐flame synthesis enables highly flexible and scalable production of multinary and high‐entropy oxide nanoparticles due to high synthesis temperatures with subsequent quenching. Temperature‐dependent in situ diffraction of as‐synthesized materials clearly reveals entropy stabilization in rock salt lattices, while spinels—featuring tetrahedral and ...

Soluble Nanomedicine Against Soluble Neurosensitizers to Effectively Relieve Osteoarthritis Pain and Joint Damage

open access: yesExploration, EarlyView.
Osteoarthritis pain arises not only from joint damage but also from inflammation, abnormal bone changes, and excessive nerve activation inside the joint. In this study, we developed an injectable nanomedicine, LAC, that responds to the acidic environment of osteoarthritic joints to locally release two approved drugs, reducing inflammation, limiting ...

Evaluation of the development potential of hot dry rock in Hainan Island

open access: yesNatural Gas Industry B
Hainan Island is located in the northwestern South China Sea at the boundary of two tectonic plates. Surface features and actual drilling have confirmed that there are rich geothermal resources in the area, with predicted resources of 480 million GWh. On
