Simply smaller: Sub-micron vaterite particles (see picture) were synthesized modifying the
crystal growth parameters. Their porous structure allows the loading and storage of various …

In photodynamic therapy (PDT), photosensitizers are required to arrive in high concentrations
at selective targets like cancer cells avoiding toxicity in healthy tissue. In this work, we …

Emission and absorption of single photons by single atoms is a fundamental limit of matter–light
interaction, manifesting its quantum mechanical nature. As a controlled process, it is …

Porous vaterite containers of 400 nm size are studied with respect to intracellular drug delivery
applications. A generic crystal phase transition from vaterite to calcite serves as a novel …

Exposure to neonicotinoid pesticides is considered one of the possible causes of honeybee
(Apis mellifera) population decline. At sublethal doses, these chemicals have been shown to …

Since their discovery in insects, pheromones are considered as ubiquitous and stereotyped
chemical messengers acting in intraspecific animal communication. Here we studied the …

We present a tunable, frequency-stabilized, narrow-bandwidth source of frequency-degenerate,
entangled photon pairs. The source is based on spontaneous parametric …

Acetylcholine is the main excitatory neurotransmitter in the honeybee brain and controls a
wide range of behaviours that ensure the survival of the individuals and of the entire colony. …

Understanding of the neural bases for complex behaviors in Hymenoptera insect species
has been limited by a lack of tools that allow measuring neuronal activity simultaneously in …

We report on experiments with cold thermal L i 7 atoms confined in combined magnetic and
electric potentials. A novel type of three-dimensional trap was formed by modulating a …
