Narratives of ‘home landscapes’ guide stewardship practices among Swedish forest owners

open access: yesPeople and Nature, EarlyView.
Abstract Production forests play an important role in addressing many of our current sustainability challenges. Therefore, how these forests are managed and what motivates the people who are managing them are important for sustainability. 47 per cent of forests in Europe are privately owned.

Performance Evaluation of Compression‐Molded Recycled Mixed Plastic Fractions From Light Packaging

open access: yesPolymer Engineering &Science, EarlyView.
Mixed HDPE/PP bottle‐cap waste was successfully processed through closed‐loop mechanical recycling. The recycled blends maintained stable thermal, rheological, and mechanical performance over multiple cycles, demonstrating the feasibility of valorizing heterogeneous polyolefin waste without advanced polymer separation.

Reservoir‐Computer auf Basis von Magnonen: Maschinelles Lernen im reziproken Raum

open access: yesPhysik in unserer Zeit, EarlyView.
Künstliche Intelligenz droht, einer der größten Energieverbraucher der Menschheit zu werden. Der Grund liegt in der geringen Effizienz der herkömmlichen Halbleitertechnologie. Abhilfe versprechen radikal neue Konzepte. An einem solchen Konzept forschen wir: Ein sogenannter Reservoir‐Computer, der Magnonen, also Spinwellen, nutzt.

Investigation of the laser fluence and wavelength dependence in surface‐assisted laser desorption/ionization mass spectrometry using gold nanoparticles

open access: yesRapid Communications in Mass Spectrometry, EarlyView.
Rationale Surface‐assisted laser desorption/ionization (SALDI) mass spectrometry (MS) builds on the use of nanostructured surfaces (e.g., coatings of colloidal nanoparticles) to promote analyte desorption and ionization. The SALDI process is believed to occur mainly through thermal processes, resulting from heating of the nanosubstrate upon absorption ...

Knee height is often right: evaluating device height effects on camera trapping rate

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Camera trap deployment height can introduce systematic biases in detection trapping rates across species of different body sizes. Combining 172 paired sampling points in five experiments across Europe, North America and Africa, our results show that low cameras significantly increase detections of small‐ and medium‐sized species, whereas high cameras ...
