Percolation Diffusion into Self-Assembled Mesoporous Silica Microfibres
Percolation diffusion into long (11.5 cm) self-assembled, ordered mesoporous microfibres is studied using optical transmission and laser ablation inductive coupled mass spectrometry (LA-ICP-MS).

A circular upcycling strategy transforms waste poly(ethylene terephthalate) bottles into microwave‐responsive Ni@C catalyst featuring lattice‐distorted nickel cores and defective carbon shells. These strain‐rich heterointerfaces enhance dielectric loss and promote localized microwave hotspots, accelerating peroxymonosulfate activation and polymer‐chain

Determination of Elemental Concentrations in Lichens Using ICP-AES/MS
Lichens are good biomonitors for air pollution because of their high enrichment capability of atmospheric chemical elements. To monitor atmospheric element deposition using lichens, it is important to obtain information on the multi-element ...

Engineering Metal‐Pocket Cooperativity in Single‐Atom COF Nanozymes for Selective Cascade Catalysis
A multilevel programming strategy is developed to engineer single‐atom COF nanozymes with tunable metal centers and chiral pockets inspired by heme–pocket cooperativity. This approach enables controlled metal–pocket interplay for asymmetric cascade catalysis, delivering high activity, selectivity, and recyclability in an asymmetric oxidation–aldol ...

Crystal orientation and domain engineering enable bulk mirror symmetry breaking in Bi1−xSbx, resulting in ultralow current‐induced switching of perpendicular magnetization without an external field. By exploiting single‐domain Bi1−xSbx (012), the authors demonstrate an out‐of‐plane spin Hall conductivity of ∼1.12×105ℏ2eΩ−1m−1$ \sim \!1.12 \ensuremath ...

Mangán eloszlásának vizsgálata biológiai mintákban LA-ICP-MS módszerrel
Diplomamunkámban módszert dolgoztam ki biológiai szövetmináták mangán tartalmának és eloszlásának vizsgálatára LA-ICP-MS módszerrel. A vizsgálatok során hentesüzletből származó veséből készítettem metszetet, majd szárazjégen fagyasztottam és ezt követően
