“…Importantly, the reaction leaves the ferromagnetic ordering of the surface alloy intact, as unambiguously established by temperature-dependent XAS and XMCD measurements. This opens a pathway to spin-polarized STM studies 22 of carbon-based magnetism due to an imbalance in sublattice occupation such as in chiral GNRs, 20,46,47 GNRs with pure zigazag edge topology, 19 or the recently synthesized triangulene. 48 An alternative route to the purely carbon-based magnetism is the study of on-surface-synthesized molecular magnets such as salophenato(Co) oligomers.…”

“…14,15 Such on-surface Ullmann reactions enable the synthesis of not only complex one-and two-dimensional covalently bonded functional networks 15 or molecular spinchains 16 but also custom-tailored graphene nanoribbons. 17,18 The ability to study such in situ synthesized structures, which offer an atomic precision of the product with control even over the edge topology, 19,20 under precisely controlled experimental conditions and in direct contact with a ferromagnetic substrate is of fundamental interest, as it is envisioned as a promising route for studying the many phenomena of emergent carbonbased spintronics 21 by means of spin-resolved measurement techniques offering submolecular spatial resolution. 22 Moreover, the enhanced thermal and structural stability of covalently bonded structures offers possibilities toward applications in particular if synthesized products extend into mesoscale dimensions accessible for device fabrication.…”

The high reactivity of magnetic substrates toward molecular overlayers has so far inhibited the realization of more sophisticated on-surface reactions, thereby depriving these interfaces of a significant class of chemically tailored organics such as graphene nanoribbons, oligonuclear spin-chains, and metal-organic networks. Here, we present a multitechnique characterization of the polymerization of 4,4″-dibromo-p-terphenyl precursors into ordered poly(p-phenylene) arrays on top of the bimetallic GdAu surface alloy. The activation temperatures for bromine scission and subsequent homocoupling of molecular precursors were followed by temperature-dependent X-ray photoelectron spectroscopy. The structural characterizations of supramolecular and polymeric phases, performed by low-energy electron diffraction and scanning tunneling microscopy, establish an extraordinary degree of order extending into the mesoscale. Taking advantage of the high homogeneity, the electronic structure of the valence band was determined with angle-resolved photoemission spectroscopy. Importantly, the transition of localized molecular orbitals into a highly dispersive π-band, the fingerprint of successful polymerization, was observed while leaving all surface-related bands intact. Moreover, ferromagnetic ordering in the GdAu alloy was demonstrated for all phases by X-ray absorption spectroscopy. The transfer of well-established in situ methods for growing covalently bonded macromolecules with atomic precision onto magnetic rare-earth alloys is an important step toward toward studying and controlling intrinsic carbon- and rare-earth-based magnetism.

“…Standard of care includes nonsteroidal anti‐inflammatory drugs, tricyclic antidepressants, serotonin and noradrenalin reuptake inhibitors, pregabalin, and gabapentin among others 5 . If these prove ineffective, PRTH often responds well to local corticosteroid plus anesthetic injections (62%–98% 2,3 ); however, remission typically lasts 18 months, 4 requiring periodic treatment and potentially elevating the risk of side effects, ranging from mild (localized bruising, hematoma) to rare and severe (central retinal artery occlusion) 6,7 …”

In this case series, we report the initial PRTH patients successfully treated with onabotulinumtoxinA (BoNTA).…”

ObjectivesTo report the efficacy of onabotulinumtoxinA (BoNTA) injections in relieving pain in patients with primary trochlear headache (PRTH).MethodsExamination of medical records for patients diagnosed with PRTH according to the International Classification of Headache Disorders, 3rd edition criteria and treated with BoNTA. Data were collected for variables related to pain relief, duration of effectiveness, and adverse effects.ResultsSix patients were included in the study. All had previously undergone standard care interventions, including infiltrations or oral treatments, yet experienced treatment failure or symptom recurrence. All patients received 20 units of BoNTA, administered in the corrugator and procerus muscles. Subsequent to the BoNTA injections, all six patients reported substantial pain relief, with five achieving complete remission of symptoms. The analgesic effect persisted for a duration of 3 months. No adverse events were reported in any of the cases.ConclusionsOur case series presents the first evidence of the potential of BoNTA as a safe and effective treatment option for PRTH. From a clinical standpoint, having a safer alternative is of paramount significance for patients with limited treatment options, such as those with PRTH. Further research is warranted to validate these findings and explore the long‐term efficacy of BoNTA in PRTH management.
