AI Article Synopsis
- Dinuclear transition metal complexes with direct metal-metal interactions can create unique reactivities and properties.
- The study introduces a new type of tetragonal lantern Fe(II) triazenides [Fe(NBuR)], where different alkyl substituents on triazine ligands result in similar short Fe-Fe distances (2.167-2.174 Å).
- These newly synthesized complexes are air-sensitive and exhibit a lower spin ground state, as confirmed by various analytical techniques including Mössbauer, H NMR, and DFT studies.
Article Abstract
Dinuclear transition metal complexes with direct metal-metal interactions have the potential to generate unique reactivities and properties. Using asymmetric triazine ligands HNBuR (R = Et, Pr, Bu) featuring different alkyl substituents at 1,3-N centers, we report here the first rational synthesis of 'tetragonal lantern' type Fe(II) triazenides [Fe(NBuR)] [R = Et (1), Pr (2), Bu (3)] having an exceptionally short Fe-Fe distance (2.167-2.174 Å). Unlike the previously reported lantern structures with related amidinate or guanidinate ligands, highly air-sensitive 1-3 show a lower spin ground state, as indicated by Mössbauer, H NMR and DFT studies.

Platform development toward ultra-intense laser-based simultaneous hard x-ray and MeV neutron multimodal radiography.
Rev Sci Instrum

Ultra-intense short-pulse lasers interacting with matter are capable of generating exceptionally bright secondary radiation sources. The short pulse duration (picoseconds to nanoseconds), small source size (sub-mm), and comparable high peak flux to conventional single particle sources make them an attractive source for radiography using a combination of particle species, known as multimodal imaging. Simultaneous x-ray and MeV neutron imaging of multi-material objects can yield unique advantages for material segmentation and identification within the full sample.

The Lanzhou lily bulbs are often vulnerable to postharvest infections by pathogenic fungi, leading to lily bulb rot. This study investigated the ability of volatile organic compounds (VOCs) produced by Stenotrophomonas geniculata J-0 to control the highly pathogenic fungus Fusarium oxysporum BH-7 in postharvest Lanzhou lily bulbs. VOCs of S.

Article Synopsis
- Leptomeningeal carcinomatosis is a rare metastatic pattern in genitourinary cancer, found in less than 0.1% of cases, and can occur even after initial treatments with enfortumab vedotin (EV).
- Two cases of metastatic urothelial cancer are presented: both patients initially showed positive responses to EV but later developed severe neurologic symptoms due to leptomeningeal metastases confirmed through imaging and cytology.
- The cases highlight an unusual progression pattern among patients treated with EV, suggesting the need for further investigation into this type of cancer spread.
A review of short-term weather impacts on honey production.

Beekeeping is an exceptionally weather-sensitive agricultural field. Honey production and pollination services depend on the complex interaction of plants and bees, both of which are impacted by short-term weather changes. In this review, classical and recent research is collected to provide an overview on short-term atmospheric factors influencing honey production, and the optimal and critical weather conditions for bee activity.
