Navigating conservation strategies: linking material research on alum-treated wood from the Oseberg collection to conservation decisions

open access: yesHeritage Science, 2018
From the mid-1800s to the late 1950s, conservation by alum salts (aluminum potassium sulfate dodecahydrate)—with some variations—was a routine method for treating highly deteriorated waterlogged archaeological wood in many countries, especially in ...

Comparative chemical investigations of alum treated archaeological wood from various museum collections

open access: yesHeritage Science, 2021
From the mid-1800s to the late 1960s, conservation by alum salts (KAl(SO4)2·12H2O—potassium aluminium sulphate), using various recipes, was a common method to prevent shrinkage and to strengthen waterlogged archaeological wooden objects.

Temperature- and humidity-induced changes in alum-treated wood: a qualitative X-ray diffraction study

open access: yesHeritage Science, 2018
Alum-treated wooden artefacts suffer from extreme deterioration, and the stability of these objects and the salts they contain to variations in climate conditions is an important issue.

Library preparation method and DNA source influence endogenous DNA recovery from 100‐year‐old avian museum specimens

open access: yesEcology and Evolution, 2023
Museum specimens collected prior to cryogenic tissue storage are increasingly being used as genetic resources, and though high‐throughput sequencing is becoming more cost‐efficient, whole genome sequencing (WGS) of historical DNA (hDNA) remains ...

DATA MODELING FOR MUSEUM COLLECTIONS [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019
Abstract. The relationship between cultural heritage, digital technologies and visual models involves an increasingly wide area of research, oriented towards the renewal of archives and museums for the preservation and promotion of culture. Recent research activities are the result of the progressive strengthening of digital technologies and the needs ...

A New Switchable Zr12 Oxocluster Based Large Pore Metal–Organic Framework Functionalized With Spin Crossover Complexes for Acetic Acid Colorimetric Sensing

open access: yesAngewandte Chemie, EarlyView.
We present here (1)⊂MIP‐216(Zr), a new hybrid material composed of an FeII spin crossover complex (1) loaded in the pores of a new hydrophobic metal–organic framework (MIP‐216(Zr), that presents a high affinity toward acetic acid and acts as a highly sensitive colorimetric sensor of acetic acid vapor due to a spin state switching of the encapsulated ...

Ammonium alum in alum-treated wooden artefacts: discovery, origins and consequences

open access: yesHeritage Science, 2019
Alum-treatment was extensively applied to archaeological wood from the Oseberg collection in the early 1900s, and was a common conservation method at the time involving impregnating objects with hot concentrated solutions of potassium alum (KAl(SO4)2 ...
