Electronic textiles offer exciting
opportunities for an emerging
class of electronic technology featuring intimate interaction with
the human body. Among various functional components, a stretchable
conductive textile represents a key building material to support the
development of sensors, interconnects, and electrical contacts. In
this study, a conductive textile is synthesized by bottom-up coassembly
of silver nanowires and TPU microfibers. The conformal coverage of
AgNW network over individual TPU microfibers gives rise to coherent
deformations to mitigate the actual strain for enhanced stretchability
and durability. The as-prepared conductive microtextile exhibits a
series of desirable properties including excellent conductivity (>5000
S cm–1), exceptional stretchability (∼600%
strain), soft mechanical properties, breathability, and washability.
The practical implementation is demonstrated by fabricating an integrated
epidermal sensing sleeve for multichannel EMG signal recordings, which
supports real-time hand gesture recognitions powered by machine learning
algorithm as a smart human–machine interface. The conductive
textile reported in this study is well suited for garment integrated
electronics with potential applications in health monitoring, robotic
prosthetics, and competitive sports.
The present study was aimed at the comparison of the pharmacokinetics of pure chlorogenic acid and extract of Solanum lyratum Thunb. The animals were allocated to two groups, and were administered chlorogenic acid or extract of S. lyratum Thunb. at a dose of 50.0 mg/kg orally. Blood samples were collected up to 8 h post-dosing. Plasma chlorogenic acid analyses were performed using an HPLC method with UV detector. The pharmacokinetic parameters were evaluated using non-compartmental assessment. Significant differences existed in the two groups for AUC0−t, AUC0−∞ and CLz/F. The reliable HPLC method was successfully applied to the determination of chlorogenic acid in rat plasma at dosage of 50.0 mg/kg.
Phase equilibria of the quaternary systems (KCl + CaCl 2 + SrCl 2 + H 2 O) and (LiCl + NaCl + SrCl 2 + H 2 O) at 288.15 K and 0.1 MPa were studied using the isothermal dissolution method, and the phase diagrams of the two systems mentioned above were plotted. There are two invariant points and four crystallization regions in the quaternary system (KCl + CaCl 2 + SrCl 2 + H 2 O). Besides the crystallization regions of the minerals KCl, CaCl 2 •6H 2 O, and SrCl 2 •6H 2 O, the solid solution (Ca,Sr)Cl 2 •6H 2 O was found. The strontium and calcium salts can be separated from each other by avoiding crystallization in the solid solution region. There are two invariant points and four crystallization regions corresponding to NaCl, SrCl 2 • 6H 2 O, SrCl 2 •2H 2 O, and LiCl•2H 2 O in the quaternary system (LiCl + NaCl + SrCl 2 + H 2 O). Lithium chloride has a strong salting-out effect on NaCl and SrCl 2 •6H 2 O. The experiment results of the quaternary systems (KCl + CaCl 2 + SrCl 2 + H 2 O) and (LiCl + NaCl + SrCl 2 + H 2 O) have a significant value for separating and purifying minerals from the oilfield brine in the Nanyishan Section of the Qaidam Basin.
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.
