‘Copper and Bronze in Art’ and the Search for Rare Corrosion Products

open access: yesHeritage, 2023
The information taken from David A. Scott’s book “Copper and Bronze in Art” was crucial for this research on copper corrosion products in Stuttgart. The examples discussed are: (1) the nature and variability of ‘Black Spots’ (or ‘Brown Fuzzies’), mainly ...

Solvent-derived defects suppress adsorption in MOF-74

open access: yesNature Communications, 2023
Defects in metal-organic frameworks (MOFs) have great impact on their nano-scale structure and physiochemical properties. However, isolated defects are easily concealed when the frameworks are interrogated by typical characterization methods.

Effects of heterofunctional alkali-metal formate doping on perovskite solar cell performance

open access: yesJournal of Materiomics, 2022
Various internal and external defects present in the perovskite film are one of the main factors that cause low efficiency and stability, and in order to realize high-performance perovskite solar cells, it is necessary to develop a method to effectively ...

Improving formatting documents by coupling formatting systems [PDF]

open access: yesProceedings of the 2003 ACM symposium on Document engineering, 2003
In this paper, we present a framework for coupling an existing formatting system such as SMIL or Madeus with a formatting control system called XEF. This framework allows the coupling process to be performed at two levels: 1) the language level, which is concerned with how to link the control features of XEF and the elements of an existing formatting ...

Dependence of the Equivalent Circulation Density of Formate Drilling Fluids on the Molecular Mass of the Polymer Reagent

open access: yesEnergies, 2021
Construction of offshore gas wells is characterized by increased requirements for both the technological process in general and the technological parameters of drilling fluids in particular. Parameters and properties of the used drilling muds must meet a

The Degradation of Daguerreotypes and the Relationship with Their Multi-Material Structure: A Multimodal Investigation

open access: yesSensors, 2023
Preserving and analytically examining daguerreotypes is particularly challenging because of their multi-material and multi-component structure. Various sensors have been exploited to examine mainly the image plates of the daguerreotypes even though the ...

FORMATS TECHNIQUES, FORMATS COMMUNAUTAIRES, FORMATS D’ENGAGEMENT:

open access: yes, 2010
A l'image des communautés virtuelles traitées par Howard Rheingold, la plupart des travaux sur cettethématique partent de l'offre technique pour analyser la communauté qui se développe autour de (sur, dans, avec, grâce à) cette infrastructure (l'incertitude sur la préposition qui va qualifier la relation est significative).

DNA as in‐formation

open access: yesWIREs Forensic Science, 2022
AbstractTraces are fundamental vectors of information. This is the first of seven forensic principles formulated by the 2022 Sydney declaration. To better understand the trace as information, this article proposes the notion of in‐formation. DNA is matter in becoming. DNA changes as it travels across forensic sites and domains.
