Anthelmintic effect of Cymbopogon citratus essential oil and its nanoemulsion on sheep gastrointestinal nematodes

Revista Brasileira de Parasitologia Veterinária
The anthelmintic resistance stimulated the search for strategies for controlling gastrointestinal nematodes, including the use of free essential oils or its nanoemulsion. This study evaluated the anthelmintic efficacy of Cymbopogon citratus essential oil

Precise detection of circular dichroism in a cluster of nano-helices by photoacoustic measurements

Scientific Reports, 2017
Compact samples of nano-helices built by means of a focused ion beam technology with large bandwidth and high dichroism for circular polarization are promising for the construction of built-in-chip sensors, where the ideal transducer must be sufficiently

Performing Relevant Irradiation Experiments: The Role of Proton Flux in the Dynamic Annealing during Irradiation of Cu(In,Ga)Se2‐Based Solar Cells

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
Energetic particles make space a harsh environment that solar cells must endure. This study demonstrates that proton flux critically affects radiation damage in Cu(In,Ga)Se2 solar cells. By irradiating identical cells at different fluxes, a flux‐dependent balance between defect generation and dynamic annealing was revealed.

Substitution of Ti by Nb in Maraging Steel: Effects on Strengthening Mechanisms and Crystallographic Behavior

steel research international, EarlyView.
This work demonstrates that replacing Ti with Nb in maraging steel forms nanoscale Nb–Mo particles along boundaries, strengthening the alloy without relying on Ti phases. Heat‐treatment tuning promotes uniform crystal orientation and balanced grain boundaries, enabling strong yet ductile behavior.
