Spectroscopic Investigations of a Vandalized Contemporary Acrylic Painting on Canvas Using Model Paintings and Chemometrics. [PDF]

Chempluschem
Sequentially shifted excitation (SSE) Raman results on artificiallyaged acrylic‐based model paints and Tela (1973) canvas painting by Griffa suggest the surface enrichment in surfactant. Vandalic trait, with an orange felt‐tip pen, consists of an acrylic binder and azo‐dyes.

Upland prairie adaptive management staged‐scale restoration practices for native plant and endangered butterfly reintroduction

Ecological Solutions and Evidence, Volume 4, Issue 2, April–June 2023., 2023
This paper documents adaptive management restoration efforts to convert conventional agricultural soils back to pre‐settlement native prairie habitat for endangered species. Indigenous tribal management before settlement preserved native prairie species and their ecosystems that are now absent due to conventional land use practices.

SHINERS in cultural heritage: Can SHINERS spectra always be compared with normal Raman spectra? A study of alizarin and its adsorption in the silicon dioxide shell

Journal of Raman Spectroscopy, Volume 52, Issue 8, Page 1406-1417, August 2021., 2021
The resulting SHINERS spectra are comparable with normal Raman spectrum of alizarin adsorbed in silica, not that of isolated alizarin. Both Ag@SiO2 and Au@SiO2 were considered, and their spectra are dependent on the interaction of alizarin with silica, rather than the specific metal core within.

Ability of new protected areas to counteract losses from downgrading, downsizing, and degazettement. [PDF]

Conserv Biol
Abstract Protected area downgrading, downsizing, and degazettement (PADDD) is a common occurrence. Although PADDD is expected to weaken biodiversity protection, PADDD offsets and new unrelated protected areas (PAs) could help restore representation of biodiversity features to the reserve network affected by PADDD.

Virus‐induced spore formation as a defense mechanism in marine diatoms

New Phytologist, Volume 229, Issue 4, Page 2251-2259, February 2021., 2021
Summary Algal viruses are important contributors to carbon cycling, recycling nutrients and organic material through host lysis. Although viral infection has been described as a primary mechanism of phytoplankton mortality, little is known about host defense responses.
