From the Object to the Mould: Is there a Connection between Microstructure of a Cast Bronze Object and its Mould Material Used?

open access: yesEXARC Journal, 2012
The question studied within the framework of the Wilhelminaoord Workshop was: In which way the mould material does influence the cast structure of a bronze object?

Electron–Matter Interactions During Electron Beam Nanopatterning

open access: yesAdvanced Functional Materials, EarlyView.
This article reviews the electron–matter interactions important to nanopatterning with electron beam lithography (EBL). Electron–matter interactions, including secondary electron generation routes, polymer radiolysis, and electron beam induced charging, are discussed.

Corrosion of bronzes by extended wetting with single versus mixed acidic pollutants [PDF]

open access: yes, 2014
The corrosion of bronzes was examined in the context of single-acid versus mixed-acid (as in urban acid rain) solutions. Two bi-component bronzes (copper with either 3% Sn or 7% Sn) that closely represent those of historic artifacts were immersed for ...

Overcoming the Stability Issue for Hydrophobic Hole Transporting Layers Utilized in Tin‐Lead Perovskite and Tandem Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
A non‐annealed process is developed for non‐PEDOT:PSS inverted tin‐lead perovskite solar cells to attain PCE 22.67% for the PTAA‐based device. When PTAA is applied in an all‐perovskite tandem solar cell, a record efficiency of 28.14% is obtained with great stability for the efficiency maintaining 96% of its original value for 500 h under one‐sun ...

Now we’re Cooking with Gas! How Experimental Archaeology Challenges Modern Assumptions about Metal Recycling

open access: yesEXARC Journal, 2017
It is accepted knowledge that when re-melting alloys, some of the metal with a lower melting temperature is lost through oxidation, and more metal must be added in order to maintain the desired alloy proportions.

Geometry‐Dependent Adhesion in Transparent Monodomain Liquid Crystal Elastomers

open access: yesAdvanced Functional Materials, EarlyView.
Liquid Crystal Elastomers (LCEs) are emerging as exciting pressure‐sensitive adhesives. We examine adhesion in chemically identical elastomer films, exploring the influence of geometry (director orientation) and phase (nematic or isotropic). We demonstrate the potential of these aligned films as transparent, tunable, broad‐temperature‐range smart ...
