Microscopic Insights into Magnetic Warping and Time‐Reversal Symmetry Breaking in Topological Surface States of Rare‐Earth‐Doped Bi2Te3

Advanced Materials, EarlyView.
Magnetic doping of the topological insulator Bi2Te3 with erbium adatoms induces out‐of‐plane magnetism and breaks time‐reversal symmetry, opening a Dirac gap and driving a Fermi surface transition from hexagonal to star‐of‐David geometry. Microscopy, spectroscopy, and magnetic dichroism reveal atomically controlled magnetic interactions that tailor the

Stuffing Improves the Stability of Fullerenelike Boron Clusters

, 2008
First-principles electronic structure calculations show that boron clusters $B_{98}$, $B_{99}$, $B_{100}$, $B_{101}$, and $B_{102}$ based on icosahedral-$B_{12}$ stuffed fullerenes are more stable than the fullerenelike boron clusters.

Closo-Carboranyl- and Metallacarboranyl [1,2,3]triazolyl-Decorated Lapatinib-Scaffold for Cancer Therapy Combining Tyrosine Kinase Inhibition and Boron Neutron Capture Therapy

Cells, 2020
One of the driving forces of carcinogenesis in humans is the aberrant activation of receptors; consequently, one of the most promising mechanisms for cancer treatment is receptor inhibition by chemotherapy.

Boron clustering in implanted NiSi

Scripta Materialia, 2011
B redistribution in a B-implanted polycrystalline NiSi layer has been investigated using atom probe tomography and secondary ion mass spectrometry. The B accumulations observed at the SiO2/NiSi interface and in the NiSi bulk are due to B clustering.

Water Permeates and Plasticizes Amorphous Carbon Dots: Unraveling the Inner Accessibility of the Nanoparticles by Glass Transition Studies

Advanced Materials, EarlyView.
The water permeability of amorphous carbon dots (CDs) is demonstrated by investigating their plasticization. Novel polyamide‐based and amorphous nanoparticles are synthesized by controlling their inner packing density. Water plasticization is evidenced by the decrease of the CDs glass transition temperature with increasing the hydration degree.

Fragmentation and Coulomb explosion of multicharged small boron clusters

, 2012
We extensively study the fragmentation and Coulomb explosion of multiply charged small boron clusters B-n (n = 2-13), where n is the cluster size. Our calculations are based on ab initio quantum-chemistry methods.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and
