Ultra‐Thick Carbon Microhoneycomb Cathode for High‐Capacity Lithium‐Oxygen Batteries
This work demonstrates ultra‐thick biochar‐derived carbon microhoneycomb cathodes for lithium‐oxygen batteries. The penetrated macrochannels serve as highly efficient pathways for Li+ and O2 and provide abundant accommodation space for the discharge product. The optimized cathode achieved a high areal capacity of 38.2 mAh cm–2, providing guidelines for

Pixel Strength and Digitization of Radiographs
We performed a pilot study to compare the digitized images of panoramic radiographs with the original film images for perceived clarity and diagnostic quality, and to make comparison amongst the digitized film images captured by a digital camera at ...

Omnidirectional underwater surveying and telepresence [PDF]
Exploratory dives are traditionally the first step for marine scientists to acquire information on a previously unknown area of scientific interest. Manned submersibles have been the platform of choice for such exploration, as they allow a high level ...

Triaxial compression tests under unloading confining pressure conditions were conducted to systematically analyze the permeability behavior of granite retrieved from the different classification surrounding rocks. Abstract The rock mass within mountain tunnels undergoes complex changes in permeability, strength, and deformation during tunneling ...

Surface hydration‐induced damage in tight oil‐bearing sandy conglomerate reservoirs
A series of techniques such as X‐ray diffraction, scanning electron microscopy, energy‐dispersive spectroscopy, conductivity tests, and infrared thermal imaging were used. The key findings are the identification of a two‐stage surface hydration process and the elucidation of the effects of various minerals and elements on the hydration process ...

The energy level mismatch of the perovskite/carbon back interface is decreased remarkably by using B, N co‐doped carbon sphere electrode in C‐PSCs, leading to effective charge carrier separation, extraction, and transport at the back interface. Combined with further buried modification using AMPA, the power conversion efficiency of the C‐PSCs is up to ...

Abstract Objective Expanded indications, diagnostic tools, and treatment options have transformed the landscape of modern pediatric epilepsy surgery. Published real‐world experiences from large surgical cohorts are still needed. To close this gap, we evaluated access, indications, treatment, and outcomes in a contemporary pediatric epilepsy surgery ...
