Operational analysis of electric field mills as lightning warning systems in Colombia

open access: yes2012 International Conference on Lightning Protection (ICLP), 2012
Electrostatic field measurements obtained in Bogota-Colombia during thunderstorm episodes in November (common raining season due to the intertropical confluence zone over central Colombia) were used to study the performance of an isolated electric field sensor and analyze its most important operational characteristics.

3D‐Printed Sulfur‐Derived Polymers With Controlled Architectures for Lithium‐Sulfur Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Rheology‐guided formulation design for direct ink writing enables the fabrication of 3D sulfur copolymer cathodes with controlled architectures for lithium‐sulfur batteries. The printed electrodes exhibit multiscale porosity and high sulfur utilization, delivering enhanced electrochemical performance compared to conventional cast electrodes.

The detection of the electric field vertical distribution underneath thundercloud: Principle and applications [PDF]

open access: yes
During the Florida 89 experiment at Kennedy Space Center, a new system was used in order to obtain the vertical distribution of the electric field underneath thunderstorms. It consists of a standard shutter field mill at ground level and five other field

Press Dewatering of Sludge with Applications of an Electric Field [PDF]

open access: yes, 1996
In the paper industry today, there is a rising concern over the question of what to do with the paper mill sludge. Although in the past most of the sludge was sent to a landfill, this disposal method is becoming less and less acceptable due to increasing

Raman Microscopy at the Organic–Inorganic Interfaces in Human Calcified Aortic Valves Shows the Co‐Existence of Whitlockite Crystals and Carbonated Hydroxyapatite‐Mineralized Collagen Fibrils

open access: yesAdvanced Functional Materials, EarlyView.
This study advances our understanding of aortic valve stenosis by capturing spatially resolved chemical and structural changes at the nanoscale. The findings highlight the potential of combined Raman and electron microscopy for understanding calcification mechanisms across diverse tissue types.

An operational windmill in an open-air museum as a conservation challenge: Lessons from projects recently implemented in Poland [PDF]

open access: yesMuzeológia a Kultúrne Dedičstvo
The article discusses the methods of protecting historic windmills and recognising them as valuable objects of industrial heritage. Therefore, examples of attempts to restore windmills as working mills after 2010 are discussed.

Retrieving Storm Electric Fields from Aircraft Field Mill Data. Part I: Theory

open access: yesJournal of Atmospheric and Oceanic Technology, 2006
Abstract It is shown that the problem of retrieving storm electric fields from an aircraft instrumented with several electric field mill sensors can be expressed in terms of a standard Lagrange multiplier optimization problem. The method naturally removes aircraft charge from the retrieval process without having to use a high-voltage ...

Control of Polarization and Polar Helicity in BiFeO3 by Epitaxial Strain and Interfacial Chemistry

open access: yesAdvanced Functional Materials, EarlyView.
In BiFeO3 thin films, the interplay of interfacial chemistry, electrostatics, and epitaxial strain is engineered to stabilize homohelicity in polarization textures at the domain scale. The synergistic use of a Bi2O2‐terminated Aurivillius buffer layer and a highly anisotropic compressive epitaxial strain offers new routes to control the polar‐texture ...
