Decoupling Transparency and Electron Injection in Ultrathin Ag Electrodes Using an Al/MoO3 Double Seed Layer for Transparent Quantum Dot Light‐Emitting Diodes

Nanophotonics, Volume 15, Issue 17, 11 September 2026.
Transparent quantum dot light‐emitting diodes (Tr‐QLEDs) employing an Al/MoO3 double seed layer decouple optical transparency from electron injection in ultrathin Ag electrodes. The functionally separated seed layers enable low optical loss and efficient charge injection simultaneously, resulting in improved electroluminescent performance, enhanced ...

A Four‐Terminal TiO2−x Memristor Architecture Enabling Multidimensional Associative Learning

physica status solidi (a), Volume 223, Issue 17, 9 September 2026.
This work demonstrates bidirectional Pavlovian conditioning in a single four‐terminal TiO2−x memristor device where two‐dimensional oxygen vacancy control and non‐filamentary resistive switching are realized. Extending this approach, multiple memristors arranged in an array autonomously perform multidimensional associative learning of two‐dimensional ...

Photolithographic Patterning of Colloidal Quantum Dots Enabled by Plasma‐Induced Ligand Polymerization

Advanced Materials Technologies, Volume 11, Issue 17, 3 September 2026.
Plasma‐induced ligand polymerization on colloidal quantum dots (QDs) renders them resistant to organic solvents, enabling conventional photoresist‐based photolithography. This approach achieves microscale patterning with feature sizes down to 3 µm, preserving the optical properties of the QDs and offering a simple and scalable route for QD‐based ...

Light Switchable Ionic Conductivity of Arylazopyrazole Modified Polysiloxanes

Advanced Materials Technologies, Volume 11, Issue 15, 7 August 2026.
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.

COMPARISON OF IODINE DETERMINATION IN SPINACH USING 2% CH3COOH AND TMAH

Acta Scientiarum Polonorum: Hortorum Cultus, 2011
Tetramethylammonium hydroxide (TMAH) is the compound most commonly applied for iodine determination in environmental samples but, at the same time, is very harmful for human health when used as an analytical reagent.

Structural characterization of bio- and geo-macromolecules by off-line thermochemolysis with tetramethylammonium hydroxide

Journal of Chromatography A, 1998
A new analytical procedure, tetramethylammonium hydroxide thermochemolysis, was used to structurally characterize a variety of bio-and geo-polymers. The technique cleaves esters and some ethers in macromolecular organic matter, yielding low-molecular-mass monomers such as methyl esters of carboxylic acids and methyl ethers of alcohols that are amenable

Quasi‐Standard Platform of AlScN Piezoelectric Integrated MEMS Technology (PIMT) For Multi‐Project Wafer Fabrication

Advanced Sensor Research, Volume 5, Issue 8, August 2026.
This report presents an 8‐inch quasi‐standard piezoelectric integrated MEMS technology (PIMT) platform which, through the integration of core and additional processes, reliably supports three rounds of multi‐project wafer (MPW) fabrication. Whilst ensuring support for mass production processes, the platform offers certain flexibility, providing a ...

Cellulose as a Platform for Biodegradable Metasurfaces: THz Characterization and Fabrication

Advanced Sustainable Systems, Volume 10, Issue 8, August 2026.
The demand for sustainable THz technologies has motivated the development of biodegradable, flexible devices based on ethyl cellulose. Metal‐backed EC metasurfaces were analytically designed and fabricated to achieve near‐perfect THz absorption. Reflection‐mode THz spectroscopy confirmed resonant absorption at 0.576 and 0.411 THz, demonstrating the ...
