Coupled Rotary Motion in Molecular Motors.

Biological molecular machines play a pivotal role in sustaining life by producing a controlled and directional motion. Artificial molecular machines aim to mimic this motion, to exploit and tune the nanoscale produced motion to power dynamic molecular systems. The precise control, transfer, and amplification of the molecular-level motion is crucial to harness the potential of synthetic molecular motors.

Juggling Optoelectronics and Catalysis: The Dual Talents of Bench Stable 1,4-Azaborinines.

Boron- and nitrogen-doped polycyclic aromatic hydrocarbons (B-PAHs) have established a strong foothold in the realm of organic electronics. However, their catalytic potential remains largely untapped. In this study, we synthesise and characterise two bench stable B,N-doped PAH derivatives based on a 1,4-azaborinine motif.

[Clinical research: who owns the data?].

The data obtained in a clinical trial are facts and cannot formally be owned by anybody. However, knowledge that results from these facts can be proprietary and represents considerable commercial value. Clinical research with medicines or devices is often a collaboration between scientists and commercial companies, and this may generate a dilemma.

Novel genes and alleles of the BTB/POZ protein family in Oryza rufipogon.

The BTB/POZ family of proteins is widespread in plants and animals, playing important roles in development, growth, metabolism, and environmental responses. Although members of the expanded BTB/POZ gene family (OsBTB) have been identified in cultivated rice (Oryza sativa), their conservation, novelty, and potential applications for allele mining in O. rufipogon, the direct progenitor of O.

E-selective Semi-hydrogenation of Alkynes under Mild Conditions by a Diruthenium Hydride Complex.

The synthesis, characterization and catalytic activity of a new class of diruthenium hydrido carbonyl complexes bound to the PNNP expanded pincer ligand is described. Reacting PNNP with two equiv of RuHCl(PPh ) (CO) at 140 °C produces an insoluble air-stable complex, which was structurally characterized as [Ru ( PNNP)H(μ-H)Cl(μ-Cl)(CO) ] (1) using solid-state NMR, IR and X-ray absorption spectroscopies and follow-up reactivity. A reaction with KOtBu results in deprotonation of a methylene linker to produce [Ru ( PNNP )H(μ-H)(μ-OtBu)(CO) ] (3) featuring a partially dearomatized naphthyridine core.
