Vertically Aligned Carbon Nanotube Mechano‐Electrochemical Generator for Ultralow‐Frequency Ocean Wave Monitoring

open access: yesAdvanced Science, EarlyView.
A mechano‐electrochemical generator is proposed that harvests energy from ultralow‐frequency waves below 0.01 Hz for self‐powered disaster monitoring. The generator minimizes signal distortion, enabling precise measurement of subtle waves with overlapping frequencies.

On the Correct Use of Statistical Tests: Reply to "Lies, damned lies and statistics (in Geology)"

open access: yes, 2011
In a Forum published in EOS Transactions AGU (2009) entitled "Lies, damned lies and statistics (in Geology)", Vermeesch (2009) claims that "statistical significant is not the same as geological significant", in other words, statistical tests may be ...

Degradation Pathways in Lithium‐Ion Batteries with Ethylene Carbonate‐Free Electrolytes

open access: yesAdvanced Energy Materials, EarlyView.
The choice of electrolyte solvent can significantly affect the oxygen loss at the Ni‐rich cathode surface. EC‐free electrolyte is found to suppress lattice oxygen release and reduce surface layer formation at NMC, resulting in improved capacity retention compared to conventional EC containing electrolytes. Abstract The development of stable electrolyte

Characterization and Reuse of Lithium‐ion Battery Cathode Material Recovered Through a Bacterial Process

open access: yesAdvanced Energy Materials, EarlyView.
A sustainable bacteria‐based lithium‐ion battery cathode recycling method is optimized using engineering biology. The resulting biomineralized manganese carbonate species is found to be easily converted into an electrode material, via simple calcination.

Intelligent Drilling Depth Monitoring System for Geotechnical Site Investigation

open access: yesShock and Vibration, 2022
The drillhole depth is an indispensable parameter in the exploration process of drilling and coring engineering, but it is mainly calculated by manually counting the number of drill pipes.

Note on the importance of hydrocarbon fill for reservoir quality prediction in sandstones [PDF]

open access: yes, 2002
Oil emplacement retarded the rate of quartz cementation in the Brae Formation deep-water sandstone reservoirs of the Miller and Kingfisher fields (United Kingdom North Sea), thus preserving porosity despite the rocks' being buried to depths of 4 km and ...
