Comparing head muscles among Drusinae clades (Insecta: Trichoptera) reveals high congruence despite strong contrasts in head shape

Scientific Reports, 2022
The subfamily Drusinae (Limnephilidae, Trichoptera) comprises a range of species exhibiting differently shaped head capsules in their larval stages. These correspond to evolutionary lineages pursuing different larval feeding ecologies, each of which uses

Biocompatibility of a droplet-mixing device using an electro-conjugate fluid

Mechanical Engineering Journal, 2016
An electro-conjugate fluid (ECF) is a type of functional fluid that produces a jet flow under a non-uniform electric field. We use an ECF to generate a rotational flow in a tiny cylindrical chamber.
