Efficient removal of succinic acid by continuous hydrodynamic cavitation combined with ozone and side influent injection.

Micropollutants (MPs) encompass a range of human-made pollutants present in trace amounts in environmental systems. MPs include pharmaceuticals, personal care products, pesticides, persistent organic pollutants, micro- and nano-plastics, and artificial sweeteners, all posing ecological risks. Conventional municipal wastewater treatment methods often face challenges in completely removing MPs due to their chemical characteristics, stability, and resistance to biodegradation.

Multiple Stabilization Effects of Benzylhydrazine on Scalable Perovskite Precursor Inks for Improved Perovskite Solar Cell Production.

Perovskite precursor inks suffer various forms of degradation, such as iodide anion oxidation and organic cation breakdown, hindering reliable perovskite solar cell manufacturing. Here we report that benzylhydrazine hydrochloride (BHC) not only retards the buildup of iodine as previously reported but also prevents the breakdown of organic cations. Through investigating BHC and iodine chemical reactions, we elucidate protonation and dehydration mechanisms, converting BHC to harmless volatile compounds, thus preserving perovskite film crystallization and solar cell performance.

Evidence-based practice - implementation level and attitude among physical, occupational, and speech and language therapists in Germany: status quo.

Introduction: Evidence-based practice (EBP) is an important component of clinical practice in public health. Its implementation involves interpreting scientific studies and then applying this knowledge to clinical decision-making. In Germany, the therapy professions are often trained in non-academic medical schools, and only a small number of therapists are university graduates.

Synthesis of a Non-Symmetrical Disorazole C-Analogue and Its Biological Activity.

The synthesis of a novel disorazole C analogue is described, and its biological activity as a cytotoxic compound is reported. Based on our convergent and flexible route to the disorazole core, we wish to report a robust strategy to synthesize a non-symmetrical disorazole in which we couple one half of the molecule containing the naturally occurring oxazole heterocycle and the second half of the disorazole macrocycle containing a thiazole heterocycle. This resulted in a very unusual non-symmetrical disorazole C analogue containing two different heterocycles, and its biological activity was studied.

Discovery and characterisation of a broderol-like illudin, omphaderol in the mycelial extracts of Omphalotus mexicanus (Omphalotaceae) using UPLC-QTOF-MS and NMR spectroscopy.

Introduction: The genus Omphalotus, in particular the "Jack-O'Lantern mushrooms" Omphalotus illudens and Omphalotus olearius, are famous for the production of the DNA-alkylating illudins. A lesser-known species, Omphalotus mexicanus, native to Central America, also produces cytotoxic illudins S and M, but its minor secondary metabolites are yet to be investigated.

Objective: To identify, isolate, and elucidate the structure of novel secondary metabolites of the illudin family in mycelial extracts of O.
