8-(1H-Benzo[d]imidazol-2-yl) quinolin-7-ol (HQB) has structural asymmetry and encloses double hydrogen bonds (HBs), which undergo excited state intramolecular charge transfer and double proton transfer (ESICT/ESIDPT). The HQB exhibits three absorption peaks...
To provide a more sustainable future, development and
implementation
of green electronics incorporating natural materials has become an
essential requirement. In this study, we demonstrated a low-temperature
and low-cost fabrication route to develop chitosan/PVP (CHP) substrate
for flexible electronics device applications. A combination of natural
polymer (chitosan) and synthetic polymer (poly(vinylpyrrolidone),
PVP) has been used to fabricate biodegradable, low-cost, and flexible
substrate. The CHP substrate has been prepared by the solution casting
method. The CHP flexible substrate demonstrates a high optical transmittance
(∼90% in the visible region), high-temperature stability (up
to 250 °C), smooth surface, and good mechanical stability along
with a high biodegradation rate (within 6 days) into the soil. Radio
frequency (RF) sputtering and thermal evaporation techniques have
been used to deposit high-quality ZnO thin films and Au/Ti electrodes
over the CHP substrate. This fabricated metal–semiconductor–metal
(MSM) device gives a clear indication about the accountability of
the CHP polymer substrate as a potential option for flexible electronics.
The current–voltage characteristic with flat and bending cycles
(three flat–bending–flat cycles) shows almost same current
conduction. These flexible CHP substrates can find a new way toward
environmentally friendly, flexible electronics.
Latent fingerprints (LFPs) identification is of paramount importance for national security and criminal investigations. We designed and synthesized fluorescent organic molecule HPBI for rapid fluorescence imaging of latent fingerprints on...
Paper strips coated with the red-fluorescent probe DMAS-TP display a distinct blue fluorescence with 2,4,6-trinitrophenol and SiO2@DMAS-TP NPs to visualize latent fingerprints up to level 3.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
