Effects of pharmaceuticals on natural microbial communities: Tolerance development, mixture toxicity and synergistic interactions [PDF]

open access: yes, 2010
Due to our extensive use of pharmaceuticals, low concentrations (picomol-nanomol/L) end up in the aquatic environment. Antibiotics comprise a group of pharmaceuticals specifically designed to disrupt microbial biochemical processes, and might therefore

Enhancing the Performance and Photostability of Perovskite Solar Cells with a Multifunctional Light‐Management Composite

open access: yesSmall Science, Volume 5, Issue 12, December 2025.
The glass substrate in perovskite solar cells (PSC) causes high reflection, transmits UV light, and conducts heat, accelerating degradation. A multifunctional pectin/PMMA–spirobifluorene composite with haze, UV absorption and downconversion, and heat dissipation is introduced.

Disentangling the absorption lineshape of methylene blue for nanocavity strong coupling

open access: yesNanophotonics, Volume 14, Issue 27, Page 4993-5001, December 2025.
Abstract Cucurbit[7]uril molecules form non‐covalent host – guest complexes with small molecular dyes. In addition, cucurbit[7]uril can also bind gold nanoparticles on gold surfaces with a 0.9 nm gap, creating plasmonic nanocavities for the dyes, with extreme confinement of the electromagnetic field. For methylene blue in such cavities, single molecule

Effects of the Operating Point of Photovoltaic Strings on Sizing of DC‐ and AC‐Connected Energy Storage Systems for Power Smoothing

open access: yesAdvanced Energy and Sustainability Research, Volume 6, Issue 10, October 2025.
This study is based on measured current–voltage curves of a 23 module photovoltaic (PV) string. The results of the study show that, in practice, following the maximum power point (MPP) closest to the nominal MPP voltage instead of the global MPP has no major effect on sizing of energy storage systems for power smoothing of PV strings. Photovoltaic (PV)
