Abstract A fully self‐healing sensor patch consisting of an in‐plane integrated dual‐mode and a pressure with vertically electrocardiogram (ECG) electrode is reported. For full‐device self‐healing, interlayer self‐bonding by using oxime‐carbamate bond‐based polyurethane room temperature TUEG 3 capped Au nanosheet (T‐Au NS) electrodes are devised. Via the use foam prepared coating composite polyaniline onto microporous graphene foam, fabricated to detect simultaneously without interference....
Scalable and simple methods for selective extraction of pure, semiconducting (s) single-walled carbon nanotubes (SWNTs) is profound importance electronic photovoltaic applications. We report a new, one-step procedure to obtain respective large-diameter s- metallic (m)-SWNT enrichment purity in excess 99% 78%, respectively, via interaction between the aromatic dispersing agent SWNTs. The approach utilizes N-dodecyl isoalloxazine (FC12) as surfactant conjunction with sonication benchtop...
Here, we developed a one-step method for covalent edge functionalization of semiconducting MoS<sub>2</sub>with lipoic acid.
Sorted single-walled carbon nanotubes (SWNTs) are of paramount importance for their utilization in high-end optoelectronic applications. Sodium cholate (SC)-based density gradient ultracentrifugation (DGU) has been instrumental isolating small diameter (d t) SWNTs. Here, we show that SWNTs wrapped by flavin mononucleotide (FMN) as a dispersing agent sorted DGU, and sorting order reversal behavior, departing from prototypical SC-SWNT trends. Larger d t lower (ρ), buoyant ρ distribution...
Symmetry breaking of single-walled carbon nanotubes (SWNTs) has profound effects on their optoelectronic properties that are essential for fundamental study and applications. Here, we show isomeric SWNTs exhibit identical photoluminescence (PL) undergo symmetry by flavin mononucleotide (FMN) dual PLs different binding affinities (Ka). Increasing the FMN concentration leads to systematic PL shifts according structural modality handedness due breaking. Density gradient ultracentrifugation...

Highway surveillance using drones has recently been introduced for the purpose of handling traffic accidents that occur on highways and cracking down law violations. However, drone is still being used limited times at specific locations. For efficient all sections highways, it essential to build a platform surveillance. In this paper, we deal with optimization problems be solved in order systematic highway drones. First consider problem determining optimal deployment stations, which are as...
