Dual‐Site Ru Single‐Atoms and RuP Nanoclusters on N, P, and B Co‐Doped Porous Carbon for Efficient Alkaline HER and AEM Water Electrolysis

open access: yesAdvanced Functional Materials, EarlyView.
Ru single atoms and RuP nanoclusters are co‐anchored in N, P, and B co‐doped porous carbon nanospheres via in situ carbonization/phosphidation of a boronate polymer precursor. RuP activates water, while nearby Ru single atoms accelerate H2 formation through H* transfer. The catalyst delivers low overpotential and high durability in alkaline HER and AEM

Prenucleation Species Dictate Foreign Ion Incorporation in the Biomineral Precursor Amorphous Calcium Carbonate

open access: yesAdvanced Functional Materials, EarlyView.
ACC forms via aggregating prenucleation clusters that gatekeep its chemical composition. Ion identity steers the path: Ba and Sr substitute Ca in clusters, thereby inhibiting nucleation, with a dose‐dependent switch of Sr to induction. Mg partitions into Mg‐rich and Mg‐poor clusters; the latter form ACC, expelling Mg.

Multivariate factor assessment for lithogenic and anthropogenic distribution of macro and trace elements in surface water. Case study: Basin of the Bregalnica river, Republic of Macedonia

open access: yesMacedonian Journal of Chemistry and Chemical Engineering, 2016
This study presents the spatial distribution of 69 elements in the surface water of the Bregalnica river basin. The concentration of elements was determined using inductively coupled plasma with mass spectrometry (ICP-MS) and inductively coupled plasma -

Laser Engineering of HfN‐Based Nanoparticles for Safe NIR‐I Photothermal and X‐ray Enhancing Cancer Therapies

open access: yesAdvanced Functional Materials, EarlyView.
In this study, we produced HfN‐based nanoparticles via femtosecond laser ablation in acetone. The nanoparticles exhibit a red‐shifted plasmonic resonance in the NIR‐I window, colloidal stability after coating with polyethyleneglycol, and excellent biocompatibility. The photothermal and X‐ray sensitization therapeutic effects were demonstrated for tumor

Molecular Templating Enables Precise CeNiC2/Ni Heterostructures for Efficient Alkaline Hydrogen Oxidation

open access: yesAdvanced Functional Materials, EarlyView.
A series of Bi‐TMCs‐based heterostructures (CeNiC2/Ni‐x%) have been precisely constructed through a “molecular‐template”‐assisted strategy, which exhibits remarkable alkaline HOR performance derived from the strong synergy between Ni and CeNiC2 components.
