Mesoporous Carbon Thin Films with Large Mesopores as Model Material for Electrochemical Applications

open access: yesAdvanced Functional Materials, EarlyView.
Mesoporous carbon thin films possessing 70 nm mesopores are prepared on titanium substrates by soft templating of resol resins with a self‐synthesized poly(ethylene oxide)‐block‐poly(hexyl acrylate) block copolymer. A strategy to avoid corrosion of the metal substrate is presented, and the films are extensively characterized in terms of morphology ...

Advancing from MOFs and COFs to Functional Macroscopic Porous Constructs

open access: yesAdvanced Materials, EarlyView.
This review study investigates the recent progress and methodologies for manufacturing metal–organic framework (MOF) or covalent–organic framework (COF)‐based 3D structured macroscopic porous constructs with high structural integrity, providing the possibility to control their porosity across dimensions.

The dynamic effects of solar eclipses of October 25, 2022, and October 14, 2023, on GPS-derived total electron content

open access: yesGeodesy and Geodynamics
This study analyzes total electron content (TEC) variations during two solar eclipse events that occurred on October 25, 2022, and October 14, 2023. The solar eclipse of October 25, 2022, was a partial solar eclipse, while the eclipse of October 14, 2023,

Fingerless [PDF]

open access: yes, 2017
This reflective poem about the self and being in a new area is based on the total solar eclipse (dubbed the Great American Eclipse) that occurred on August 21, 2017. It explores themes similar to those raised in discussions about the case of Charity Lamb.

Interfacial Chemistry Control of In Situ Grown Gold Nanoparticles on Functionalized MXene Nanosheets

open access: yesAdvanced Materials Interfaces, EarlyView.
Gold nucleation on MXene is governed by interfacial oxidation, not termination density. An interface‐resolved pathway is uncovered in which Au nucleates at TiO2/TiOx, guided by local reduction at the surface; where tailored functionalization directs when and where nuclei form, enabling the formation of predictable heterostructures.

The ionospheric responses to the 11 August 1999 solar eclipse: observations and modeling [PDF]

open access: yesAnnales Geophysicae, 2008
A total eclipse occurred on 11 August 1999 with its path of totality passing over central Europe in the latitude range 40°–50° N. The ionospheric responses to this eclipse were measured by a wide ionosonde network.
