We use conformal symmetry to calculate the next to next to leading order (NNLO) anomalous dimension matrix (three loops) for flavor-singlet axial-vector QCD operators for spin N≤8 from a set of gauge-invariant two-point correlation functions. Combining this result with the recent calculation of the two-loop coefficient functions, we carry out the calculation of the γγ*→η and γγ*→η′ form factors at large momentum transfers to the NNLO accuracy in perturbative QCD..

The zip file 'Masspec_data.zip': Contains the raw data of the mass spectrometer measurements during the operando experiment (.rga and .ana files) for both samples. The folder also contains the exported data (.txt files) for readability and accessibility. [...]

BE-doped polycyclic aromatic hydrocarbons (PAHs; E = NR, O) often exhibit superior optoelectronic properties compared to their carbonaceous congeners. Herein, we report an efficient and convenient synthetic route to this compound class, based on the intramolecular addition of aryl(Mes)BE–H bonds to ortho-positioned butadiyne substituents. [...]

Tooth enamel of most mammals shows alternating light-dark bands, called Hunter-Schreger bands (HSB), in longitudinal sections caused by a decussating arrangement of bundles of prisms, the unit building blocks of mammalian enamel. HSB is thought to increase resistance to abrasive food and mitigate crack propagation and hence is considered a mammalian adaptation to high-efficiency mastication. [...]

Non-oxidative dehydrogenation of propane (PDH) is a well-established large-scale route for on-purpose propene production. Cobalt-based catalysts have attracted increasing attention due to their attractive performance as environmentally friendly and cost-efficient alternatives to commercially used catalysts containing chromium or platinum.

Aluminum alloys are widely used in lightweight applications but frequently suffer mechanical degradation athigh temperatures due to phase coarsening. This study presents a novel Al-6.5Ni-1.4Fe-0.9Zr (wt.%) neareutecticalloy, designed using thermodynamic principles and non-equilibrium solidification modeling to optimizeboth printability and mechanical performance.
