Synthesis and optical properties of chiral graphene quantum dots

The bottom-up synthesis of graphene-related materials has emerged as a powerful approach for the fabrication of molecularly defined nanographenes with tailored structural and electronic properties. In particular, graphene quantum dots (GQDs) have…

Investigating the effects of Ag/Au nanoparticle mixing ratios on nonlinear optical properties using femtosecond laser light

This study investigates the nonlinear optics (NLO) characteristics of colloidal silver–gold (Ag/Au) nanoparticles (NPs), synthesized in varying mixing ratios under femtosecond laser excitation. We show how to create Ag/Au NPs using a two-step…

About Carrier's Self‐Trapping and Dynamical Rashba Splitting in the 2D Hybrid Perovskite (BA)<sub>2</sub>(MA)<sub>2</sub>Pb<sub>3</sub>l<sub>10</sub>

Time‐ and Angle‐Resolved Photoelectron Spectroscopy (tr‐ARPES) is employed to monitor photoexcited electrons in the 2D hybrid perovskite (BA)2(MA)2Pb3l10. Photoelectron intensity maps are in good agreement with ab‐initio calculations of the band…

Fluorescent Nanodiamond-Based Delivery Systems for Mitochondrial Targeting of Bioactive Peptides

Mitochondria are recognized as key players affecting hallmarks of oncogenesis, tumor progression, and chemotherapy resistance, positioning this organelle as an important therapeutic target. We previously demonstrated that impairment of the AIF…

Nanoscale graphitization and defect evolution in silicon-vacancy center-containing nanodiamonds under high-pressure high-temperature annealing

Group-IV color centers, such as the silicon-vacancy (SiV) defect, are highly promising for solid-state quantum technologies. However, nanodiamonds typically exhibit significant lattice strain and structural disorder, which degrade their optical…

Scaling microalgae cultivation: from environmental effects on cell growth to a predictive hybrid modeling framework

Microalgae are photosynthetic microorganisms that convert CO₂ into valuable biomass for nutrition, biofuel production, and wastewater treatment. However, scaling from laboratory to industrial volumes remains largely empirical, as cultivation…
