Orbital apex leiomyoma with intracranial extension

open access: yes, 2000
Background: Leiomyoma is a rare, benign smooth muscle tumor of the orbit. It occasionally shows some histologic resemblance to other common tumors of the orbit like neurofibroma and schwannoma.

Advancing Energy Materials by In Situ Atomic Scale Methods

open access: yesAdvanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
Progress in in situ atomic scale methods leads to an improved understanding of new and advanced energy materials, where a local understanding of complex, inhomogeneous systems or interfaces down to the atomic scale and quantum level is required. Topics from photovoltaics, dissipation losses, phase transitions, and chemical energy conversion are ...

Gold Clusters With Open‐Shell Ligands: Superatom Mediated Magnetic Interaction

open access: yesAngewandte Chemie, EarlyView.
Open‐shell verdazyl radicals were covalently integrated with atomically precise Ir‐doped Au12 (Ir@Au12) superatoms. The resulting radical–superatom hybrids exhibit photoinduced electron transfer, spin delocalization onto the metal‐cluster core, and weak ferromagnetic communication between radicals mediated by the superatomic electronic structure ...

Bisphosphonate-induced Orbital Apex Syndrome

open access: yes
Bisphosphonates act on osteoclasts to decrease skeletal remodeling and resorption rates in the setting of osteoporosis and other skeletal conditions.1 Although typically well tolerated, bisphosphonates are rarely associated with ocular side effects.

Orbital ordering in the layered manganites [PDF]

open access: yes, 2006
The interaction between the long range correlations of electrons and the encompassing crystal structure is a key aspect of solid state physics. This thesis studies the long range interactions of the 3D orbitals in the single and bilayered manganites ...

Emerging Materials and Future Strategies for Solid Oxide Electrochemical Cells

open access: yesAdvanced Energy Materials, EarlyView.
Solid oxide electrochemical cells operate under strongly coupled electrochemical and thermodynamic conditions, where performance is constrained by interactions among crystal structure, defect chemistry, and interfacial evolution. This review, based on a structure‐defect‐property‐durability framework, reveals the roles of lattice symmetry and defect ...

Diamondiyne: A 3D Carbon Allotrope With Mixed sp–sp3 Hybridization

open access: yesAngewandte Chemie, EarlyView.
A new carbon allotrope with mixed sp–sp3 hybridization has been synthesized through delicately controlled kinetics at a liquid–liquid interface. The resulting material, termed diamondiyne, exhibits an expanded diamond‐type network in the form of small crystallites in a continuous all‐carbon film.

Why Physics Still Matters: Improving Machine Learning Prediction of Material Properties With Phonon‐Informed Datasets

open access: yesAdvanced Intelligent Discovery, EarlyView.
Phonons‐informed machine‐learning predictive models are propitious for reproducing thermal effects in computational materials science studies. Machine learning (ML) methods have become powerful tools for predicting material properties with near first‐principles accuracy and vastly reduced computational cost.

Borosulfates Hosting Se42+ Ions—Crystal Structures, Chemical Bonding, Optical Spectroscopy, and Magnetism

open access: yesAngewandte Chemie, EarlyView.
Apart from (transition) metal (oxo)halides only few hosts stabilize chalcogenide cations in purely oxoanionic coordination environment. Herein, we report on five borosulfates containing the Se42+ ion and characterize the compounds using X‐ray diffraction, diffuse reflectance spectroscopy, density functional theory (DFT) calculations along with magnetic
