Boron and Nitrogen Doped Single walled Carbon Nanotubes as Possible Dilute Magnetic Semiconductors

Nanoscale Research Letters, 2007
The structure of single walled armchair and zig-zag carbon nanotubes having 70 atoms and two carbons replaced by boron or nitrogen is obtained at minium energy using HF/6-31G* molecular orbital theory.

Ladder and zig-zag Feynman diagrams, operator formalism and conformal triangles

Journal of High Energy Physics, 2023
We develop an operator approach to the evaluation of multiple integrals for multiloop Feynman massless diagrams. A commutative family of graph building operators H α for ladder diagrams is constructed and investigated.

Convergence of Organ‐on‐a‐Chip and Freeform Printing of Sacrificial Poly(2‐cyclopropyl‐2‐oxazoline) Enables the Generation of Perfusable Endothelialized Channels in Hydrogels

Macromolecular Rapid Communications, EarlyView.
We employ freeform printing of thermo‐responsive poly(2‐oxazoline) to directly fabricate suspended sacrificial vascular templates within Organ‐on‐a‐chip devices. This enables circular, perfusable channels down to 200 µm without post‐processing.

Ambiguities in Assigning Single‐Crystal NMR Data to Individual Atoms in the Crystal Structure: A Case Study of Hambergite, Be2$$ {}_2 $$BO3$$ {}_3 $$OH, by 9Be and 11B NMR Spectroscopy, XRD Measurements and DFT Calculations

Magnetic Resonance in Chemistry, EarlyView.
The fundamental question of how to assign NMR resonances to specific atoms in the unit cell is addressed by using the 9Be and 11B spectra of the natural mineral hambergite as a model system. ABSTRACT The NMR interaction tensors of 9Be and 11B of hambergite, Be2$$ {}_2 $$BO3$$ {}_3 $$OH, were derived from single‐crystal NMR experiments.

The European honey buzzard (Pernis apivorus) as an ally for the control of the invasive yellow‐legged hornet (Vespa velutina nigrithorax)

Pest Management Science, Volume 81, Issue 4, Page 2237-2247, April 2025.
The predatory effect of the honey‐buzzard affects the reproductive performance of Asian‐hornet colonies, decreasing the density of workers over distance and time. The foraging distances of the honey‐buzzard concentrates within the first 2000 m from nest, which supports the results observed.
