Leveraging 3d-4f Coordination: Molecular Quantum Spring-Magnet Behavior in Axial Ni2Ln Complexes. [PDF]
Angew Chem Int Ed EnglWe report heterotrimetallic Ni2Ln complexes mimicking exchange spring magnets at the molecular level. CASSCF calculations show collinear anisotropy axes, while µSQUID studies reveal slow relaxation and open hysteresis in Ni2Tb, Ni2Dy, and Ni2Ho. Ferromagnetic 3d–4f coupling and anisotropy alignment enhance bistability, offering promise for quantum, and

Limnology and Oceanography: Methods, EarlyView.Abstract Consistent monitoring of seawater spectrophotometric pH on the total hydrogen ion scale (pHT) has been questioned by an evolving method, with changes in parameterization and the purity of the meta‐cresol purple (mCP). Using real seawater samples, we demonstrate that spectrophotometric pHT measurements obtained with unpurified (UNPUR) and ...

Structured and Unstructured Binding of an Intrinsically Disordered Protein as Revealed by Atomistic Simulations [PDF]
, 2016 Intrinsically disordered proteins (IDPs) are a set of proteins that lack a definite secondary structure in solution. IDPs can acquire tertiary structure when bound to their partners; therefore, the recognition process must also involve protein folding ...

Nordic Journal of Botany, EarlyView.Stemodia diplohyptoides M.M.Sosa & Dematt. and S. lobelioides Lehm. (Gratioleae, Plantaginaceae) are reported for the first time in Paraguay, found in Alto Paraná and Presidente Hayes departments, respectively. These new records extend the known geographical range of both species, representing the northern records to date, S.

Big Bird: A global dataset of birds in drone imagery annotated to species level
Remote Sensing in Ecology and Conservation, EarlyView.Drones are a valuable tool for surveying birds, but manually detecting and identifying birds in drone images is costly. We assembled a diverse dataset of 23 865 images of birds captured with 21 different drones across 11 countries. We labelled 4824 of these images, detailing the location, species, posture category, age category, and sex of 49 990 birds
