Adsorbent Materials for Hydrocarbons Removal by Geopolymerization of Halloysite Clay Nanotubes Filled Within Chitosan Matrix

open access: yesAdvanced Materials Interfaces, EarlyView.
Alkaline activation of halloysite clay nanotubes embedded in a chitosan matrix converts bionanocomposite films into porous geopolymeric materials with enhanced adsorption capacity toward hydrocarbons in both vapor and aqueous phases. The improved adsorption performance was demonstrated by the efficient capture of dodecane vapors and phenol from water ...

Microfabrication of Soft Millirobots Propelled by Low Voltage Electrohydraulic Actuators

open access: yesAdvanced Materials Technologies, EarlyView.
Manual layer‐by‐layer assembly is replaced by wafer‐level MEMS batch fabrication for compliant polymer‐based electrohydraulic actuators. The microfabricated devices integrate sacrificially defined microcavities, Parylene‐C‐sealed inlets, and multilayer polymer–metal films.

Ovaries of Puto superbus and Ceroputo pilosellae (Hemiptera: Coccoidea): Morphology, ultrastructure, phylogenetic and taxonomic implications

open access: yesEuropean Journal of Entomology, 2013
Ovaries of Puto superbus and Ceroputo pilosellae are composed of numerous short telotrophic ovarioles that are arranged around the distal part of the lateral oviduct. An individual ovariole consists of a distal trophic chamber (= tropharium) and proximal

Population-scale laboratory studies of the effect of transgenic plants on nontarget insects

open access: yes, 2001
Studies of the effects of insect-resistant transgenic plants on beneficial insects have, to date, concentrated mainly on either small-scale ‘worst case scenario’ laboratory experiments or on field trials.

Turning Light Into Matter: Programmable Microstructures Via Dose Control in Two‐Photon Polymerization

open access: yesAdvanced Optical Materials, EarlyView.
This work augments two‐photon polymerization with point‐wise dose control, enabling structures with heterogeneous material properties such as refractive index. An open source toolbox and superior calibration methodology for the refractive index pave the way for bio‐mimicking or numerically optimized structure designs, and enhance the synergy between 3D
