As the most classic photoisomerization system, azobenzene has been widely utilized as a building unit in various photoswitching applications. However, attempts to build azobenzene-based single-molecule photoswitches have met with limited success, giving low on/off ratios. Herein, we demonstrate two designs of azobenzene-based photoresponsive single-molecule junctions, based on mechanically interlocked diazocine and azobenzene-based dynamic anchors, respectively.

- The study aimed to examine how varying intervals of electroacupuncture (EA) affect the primary motor cortex's excitability and upper limb function in healthy individuals, along with observing any lasting effects from the acupuncture treatment.
- Involving fifteen healthy participants, the research utilized a self-comparison design across three stages, where participants received either one or two EA sessions, with different time intervals between them, while a control point was measured before and after the sessions.
- Results indicated significant increases in measured parameters of motor evoked potentials (MEPs), suggesting that the EA significantly enhances corticospinal excitability and motor function following treatment.
A wireless sensor network (WSN) consists of a very large number of sensors which are deployed in the specific area of interest. A sensor is an electronic device equipped with a small processor and has a small-capacity memory. The WSN has the functions of low cost, easy deployment, and random reconfiguration.
View Article and Find Full Text PDFSb nanosheets, also known as antimonene, have received ever-growing consideration as a promising new type of two-dimensional (2D) material due to their many attractive properties. However, how their nonlinear optical (NLO) properties are affected by their nanosheet structure and measurement conditions remains unclear. Herein, we report a successful size-selective production method for Sb nanosheets, which is based on a combination of lithium ion intercalation, solvent exfoliation and size selection centrifugation.

However, in molecular circuits, the quantum interference (QI) between the individual channels may lead to apparent invalidity of Kirchhoff's laws. Such an effect can be very significant in single-molecule circuits consisting of partially overlapped multiple transport channels.
