Surface Chemical Analysis of Plastic Materials by X‐Ray Photoelectron Spectroscopy: Understanding Weathering, Fragmentation and Contaminant Uptake in Marine Environments

open access: yesMacromolecular Materials and Engineering, EarlyView.
This Perspective demonstrates how X‐ray photoelectron spectroscopy (XPS) uncovers surface chemical changes in plastics, providing insight into weathering‐driven fragmentation and contaminant adsorption. The Perspective underscores XPS's pivotal role in elucidating fragmentation mechanisms, predicting pollutant–plastic interactions, and guiding ...

Developing Critical Thinking in online search [PDF]

open access: yes, 2017
Digital skills especially those related to Information Literacy, are today considered fundamental to the education of students, both at school and at university. Searching and evaluating information found on the Internet is surely an important competency.

Bound states in the 3d Ising model and implications for QCD at finite temperature and density [PDF]

open access: yes, 2001
We study the spectrum of bound states of the three dimensional Ising model in the (h,beta) plane near the critical point. We show the existence of an unbinding line, defined as the boundary of the region where bound states exist.

Novel Sulfur‐Rich Polymers from Inverse Vulcanization as Functional Building Blocks for Photonics

open access: yesMacromolecular Rapid Communications, EarlyView.
Isopropenyl aromatic comonomers, in particular novel 2,7‐diisopropenylfluorene and 2,8‐diisopropenyldibenzothiophene, synthesized by sustainable, facile, single‐step SMCCR from available brominated substrates are exploited in the Inverse Vulcanization process to obtain functional Sulfur‐rich macromolecular materials.

Results for the response function determination of the Compact Neutron Spectrometer

open access: yes, 2012
The Compact Neutron Spectrometer (CNS) is a Joint European Torus (JET) Enhancement Project, designed for fusion diagnostics in different plasma scenarios. The CNS is based on a liquid scintillator (BC501A) which allows good discrimination between neutron

Forwarding forest restoration: Seven key socio‐ecological issues for advancing forest restoration in a world in flux

open access: yesPeople and Nature, EarlyView.
Abstract Restoring forests can help conserve biodiversity, mitigate climate change and enhance human well‐being. Despite financial and political support for global forest restoration initiatives, projects continue to face persistent challenges and trade‐offs between environmental, climatic and socio‐economic goals.

The potential of seedbank digital information in plant conservation

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Seedbanks are vital for biodiversity conservation, but their potential remains underutilised due to a limited understanding of the intraspecific genetic diversity they hold. By leveraging digitised data associated with seedbank collections, such as sampling locations, number of maternal plants and seed traits, we can attempt the estimation of genetic ...
