Label‐Free Detection of a Neurotransmitter Using an Aptamer‐Functionalized Amorphous IGZO Transistor

Advanced Materials Interfaces, EarlyView.
An aptamer‐functionalized amorphous IGZO thin‐film transistor enables label‐free electrical detection of the neurotransmitter serotonin under liquid‐gated operation. Stepwise surface functionalization ensures stable biomolecule integration and efficient electrostatic coupling.

Adaptive Control with a Multi-Input Pole-Assignment for the Distillation Column

Journal of Engineering and Sustainable Development, 2010
In this paper a multivariable adaptive controller is designed to achieve a suitable control action for a binary distillation column. The system is two input and two output, where the estimated model is obtained using a multivariable identification ...

Facet‐Specific PbS Quantum Dot Passivation Using Halide Perovskites for SWIR Photodetectors

Advanced Materials Interfaces, EarlyView.
PbS quantum dots (QDs) are emerging as powerful short‐wave infrared photodetectors, yet the passivation mechanism of large QDs by perovskites ‐ critical for their stability ‐ remains unexplained. Here, we unveil the ligand structure of CH3NH3PbI3 (MAPI)‐passivated 4‐nm PbS QDs using FTIR, XPS, SEM, NMR, and DFT.

Light Switchable Ionic Conductivity of Arylazopyrazole Modified Polysiloxanes

Advanced Materials Technologies, EarlyView.
We present a polysiloxane functionalized with a novel arylazopyrazole dye that undergoes reversible photoisomerization. Upon lithium bis(trifluoromethanesulfonyl)imide addition and UV irradiation, the polymer exhibits a shift in tan(d) toward higher frequencies and enhanced ionic conductivity.

Enhancing Performance and Reliability of Hf1‐xZrxO2 Morphotropic Phase Boundary Films via Nanolaminate Structuring and Microwave Annealing

Advanced Materials Technologies, EarlyView.
Hf–Zr–O‐based morphotropic phase boundary (MPB) thin films often suffer from limited endurance and poor uniformity due to intrinsic phase instability. This work proposes a nanolaminate architecture that spatially separates competing phases, stabilizes phase formation, and suppresses wake‐up‐induced degradation.

Robust pole assignment by output feedback using optimization methods.

, 1993
A robust output feedback pole assignment method, which seeks to achieve a robust solution in the sense that the assigned poles are as insensitive as possible to perturbations in the system parameters, is studied.
