Multimaterial Microrobots for pH Sensing Fabricated Using Sequential 3D and 4D Printing with Automated Alignment

open access: yesAdvanced Materials Technologies, EarlyView.
This work proposes the use of multimaterial microrobots for pH sensing. The microrobots consist of a hard polymer backbone and 4D printed sensing elements made of a pH‐responsive hydrogel. The swelling response, reusability, and high mobility of the microrobots make them promising tools for pH sensing at the micro scale.

The role of volatiles in aggregation and host-seeking of the haematophagous poultry red mite Dermanyssus gallinae (Acari: Dermanyssidae) [PDF]

open access: yes, 2010
Infestations with ectoparasitic poultry red mites (Dermanyssus gallinae) pose an increasing threat to poultry health and welfare. Because of resistance to acaricides and higher scrutiny of poultry products, alternative and environmentally safe management

Controlled Air Gap Formation between W and TiO2 Films via Sub‐Surface TiO2 Atomic Layer Etching

open access: yesAdvanced Materials Technologies, EarlyView.
Delivering SiH4 and WF6 to a lined array of TiO2 films produces a thin film of tungsten while simultaneously, the underlying TiO2 is removed. When the W‐coated TiO2 structure is exposed to further etching cycles after deposition, TiO2 etching continues vertically and laterally, creating a self‐supported W structure and a vacant air gap.

Surface‐Mounted Metal‐Organic Framework for the Adsorption and Sensing of Monoaromatic Pollutants in Water Using Quartz Crystal Microbalance

open access: yesAdvanced Materials Technologies, EarlyView.
A hydrophobic metal‐organic framework (UHMOF‐100) is grown on a quartz crystal microbalance sensor for the first time. The device enables real‐time, selective detection of monoaromatic BTEX pollutants in water, demonstrating a new strategy for creating robust chemical sensors for challenging environmental monitoring applications. Abstract Environmental
