Abstract Powering and communication with micro robots to enable complex functions is a long-standing challenge as the size of continues shrink. Physical connection wires or components needed for wireless are limited by electronic energy storage devices, making miniaturization difficult. To explore an alternative solution, we designed fabricated soft swimming robot both powering controlling provided remote light, which does not carry any devices batteries. In this approach, polymer film...
Nanofibrillated cellulose (NFC) is becoming popular in antibacterial material due to its favorable biocompatibility, stability, and modifiable properties, which give it a great potential as template for the deposition of silver nanoparticles (Ag NPs). To investigate procedure ability Ag NPs, dialdehyde nanofobrillated (DATNFC) prepared by oxidation nanofibers was used initiate mirror reaction. Silver (∼31.07 nm) were successfully fabricated uniformly anchored onto DATNFC (DATNFC@Ag). The...
Abstract Vibronic coupling is a central issue in molecular spectroscopy. Here we investigate vibronic within single pentacene molecule real space by imaging the spatial distribution of single-molecule electroluminescence via highly localized excitation tunneling electrons controlled plasmonic junction. The observed two-spot orientation for certain vibronic-state found to be evidently different from purely electronic 0–0 transition, rotated 90°, which reflects change transition dipole along...

Dumbbell-like patterns obtained by subnanometer resolved spectroscopic imaging disclose coherent nature coupling associated while second-order photon...

In particular, annealing at...
Abstract Efficient upconversion electroluminescence is highly desirable for a broad range of optoelectronic applications, yet to date, it has been reported only ensemble systems, while the efficiency remains very low single-molecule emitters. Here we report on observation anomalously bright electroluminescence, with emission efficiencies improved by more than one order magnitude over previous studies, and even stronger normal-bias electroluminescence. Intuitively, improvement achieved via...

As controlled remote lights instead lines light-driven mode simplifies design avoids drivers complex mechanical...
Big-data fault diagnosis methods based on deep learning (DL) have been widely studied in recent years. However, the number of labeled bearing samples is limited industrial practice, and these usually are contained with complex environmental noise. Therefore, it necessary to develop a generalizable DL model strong feature ability. To tackle above challenges, this article proposes multiscale lightweight idea adversarial learning.
