Mechanism of the effect of Fe/Ca oxide on coal pyrolysis to HCN

Meitan xuebao
Fe2O3 and CaO are the main metal oxides in coal, which have an effect on NOx precursor-HCN generation during coal pyrolysis. In order to reveal the mechanism of Fe2O3 and CaO on HCN generation during coal pyrolysis, this paper adopts pyrrole as a ...

Ultra‐Flexible Dual‐Band Organic Photodetectors for Visible and Near‐Infrared Sensing

Advanced Optical Materials, EarlyView.
An ultra‐flexible dual‐band organic photodetector with a total thickness of 5.6 µm for bio‐sensing is developed. It selectively detects visible and near‐infrared light with high sensitivity by switching the voltage. Peripheral oxygen saturation (SpO2) measurement is demonstrated using the device attached to a finger under a single light source by ...

On–Off Switchable Micromotors for Use in Steerable Microvehicles

Advanced Robotics Research, EarlyView.
Electrically controllable micromotors and microvehicles are developed by tuning the diffusion of the fuel. Self‐propelled micromotors using bubble propulsion show great promise for miniaturized devices with multiuse purposes such as cargo delivery and sensing. However, there is currently no method to electrically switch the micromotors on or off. Here,

Spatial separation of pyrrole and pyrrole-water clusters [PDF]

Chemical Physics Letters, 2019
We demonstrate the spatial separation of pyrrole and pyrrole(H$_2$O) clusters from the other atomic and molecular species in a supersonically-expanded beam of pyrrole and traces of water seeded in high-pressure helium gas. The experimental results are quantitatively supported by simulations.

Textile Actuation Based on In‐Air Actuating Polypyrrole‐Based Tape Yarns for Wearable Soft Robotics: Toward On‐Body Applications

Advanced Robotics Research, EarlyView.
This work reports on the actuation behavior of CP‐based polypyrrole/PVdF TYs soaked in electrolyte/ionic liquids and woven actuators where such TYs are integrated. These studies are important toward the creation of on‐body applications such as wearable soft robotics, where textiles offer many advantages such as increased force, integrated electrical ...

Unanticipated differences between α- and γ-diaminobutyric acid-linked hairpin polyamide-alkylator conjugates [PDF]

, 2006
Hairpin polyamide–chlorambucil conjugates containing an {alpha}-diaminobutyric acid ({alpha}-DABA) turn moiety are compared to their constitutional isomers containing the well-characterized {gamma}-DABA turn.
