2D Hierarchical Black Phosphorus‐Mn2O3 Heterostructured Composites for High‐Performance Flexible Supercapacitors

open access: yesAdvanced Materials Interfaces, EarlyView.
A sonochemical strategy constructs an ex situ 2D hierarchical black phosphorus–Mn2O3 heterostructure, enabling intimate interfacial coupling, enhanced charge transport, and improved electrochemical stability. The optimized BPM‐37.5% electrode delivers 466 F g−1 with 84% retention after 8000 cycles, while the flexible device exhibits high areal energy ...

Interface Dynamics in Biomolecular Condensates by High‐Speed AFM

open access: yesAdvanced Materials Interfaces, EarlyView.
High‐speed atomic force microscopy provides nanoscale structural dynamics at the liquid interface of biomolecular condensates, key elements in several cellular pathways. By addressing the challenges of low surface tension and condensate‐induced instabilities, we achieve nanometer spatial and sub‐second temporal resolution, revealing structural ...

Determination of Moisture Diffusivity as a Function of Both Moisture and Temperature

International Journal of Thermophysics, 2011
The effect of moisture and temperature on liquid water transport in porous media was studied. Specimens of autoclaved aerated concrete were subjected to one-sided water penetration in isothermal conditions at temperatures of 20 °C, 40 °C, 60 °C, and 80 °C. After specified time intervals, moisture profiles were determined gravimetrically.

Moisture diffusion in cementitious materials Moisture capacity and diffusivity

Advanced Cement Based Materials, 1994
Abstract Based on a model by Bažant and Najjar, and using a new model for adsorption isotherms, moisture capacity and diffusivity of concrete are analyzed. The moisture capacity, obtained as a derivative of the ] adsorption isotherm, first drops as the humidity increases from zero, then levels off as a consuant, and finally again increases when the ...

Moisture diffusivity of wood

AIP Conference Proceedings, 2015
Moisture transport in four different types of wood is investigated. The specimens are subjected to one-sided water penetration in vertical direction and the moisture profiles are determined by the capacitance method. The calibration is done a posteriori using the last measured moisture profile by the gravimetric method. The moisture diffusivity is then
