We investigate the time-resolved photocurrent response of CdSe quantum dot (QD) thin films sensitized with zinc β-tetraaminophthalocyanine (Zn4APc) (Kumar , ACS Appl. Mater. Interfaces, 2019, 11, 48271-48280) on three different substrates, namely, silicon 230 nm SiO2 dielectric, glass, and polyimide. While Si/SiO2 (230 nm) is not suitable for any transient characterization due to an interfering...

A study of the effect ammonia vapor and solution on optical fibers in acrylate, polyimide carbon/polyimide coatings was carried out to determine degree degradation mechanical characteristics an alkaline environment. The ultimate strength measured by two-point bending method, coating condition after interaction with monitored microscope. decrease tensile recorded for all examined types protectiv...

Photolithography is a highly advanced method for fabricating features in the micron and submicron size range. Semiconductor processing methods have been applied to fabricate microsensors and microactuators with high throughput and excellent dimensional control of small features, usually from silicon. It is clearly desirable to extend these methods to microfabricate other materials, such as piez...

Abstract Laser‐induced graphene sensors have attracted considerable interest in various fields; however, the low sensitivity and conformability limit their further applications measuring soft, large deformable structures. Here, an innovative method of interface ablation is presented to convert interfacial polyimide into by nanosecond ultraviolet laser (308 nm). Significantly different from trad...

In this work, innovative biosourced polyimide polymers were derived from novel combinations of monomers (Isosorbide, 6-FDA and amine cardo). These obtained with satisfactory yields by polycondensation different percentages isosorbide (from 100% to 0%). The synthesized polyimides had number average molecular weight in the 17,600–22,000 g/mol range, they stable well above 451 °C (5% loss N2). gla...
