Large-Scale Patterning and Polymorph Transition of Conjugated Polymers via Meniscus-Guided Deposition for Field-Effect Transistors.

The ability to craft patterned conjugated polymers and simultaneously induce polymorph transitions within these patterns is important for various organic semiconductor devices. However, simple and straightforward routes to achieving both desirable characteristics remain a grand challenge. Herein, we report an effective meniscus-guided deposition (MGD) strategy to generate highly ordered, periodic microscopic patterns (i.

Rapid Meniscus-Assisted Solution Printing of Large-Area Stripe Arrays of Highly Oriented Conjugated Polymers for Field-Effect Transistors.

The ability to pattern semiconducting conjugated polymers (CPs) and concurrently enable their highly oriented chains represents an important endeavor to render their high charge mobility for electronic devices. However, simple yet generalizable routes to CPs with such desirable characteristics are limited. Herein, we report a robust meniscus-assisted solution printing (MASP) strategy to craft arrays of donor-acceptor CP stripes and scrutinize the correlation between different stripes and their charge transport attributes.

Chemerin Regulates the Proliferation and Migration of Pulmonary Arterial Smooth Muscle Cells the ERK1/2 Signaling Pathway.

Pulmonary arterial hypertension (PAH) is an incurable disease with high mortality. Chemerin has been found to be associated with pulmonary hypertension (PH). However, the specific role of chemerin in mediating PH development remains unclear.

An environmental-friendly pesticide-fertilizer combination fabricated by in-situ synthesis of ZIF-8.

Stimulus-responsive pesticide or fertilizer systems have been emerged to improve the use efficiency of agrochemicals, reduce over-application and ensuing environmental problems. However, environmental-friendly synthesis of these systems still remain challenging. In this work, an environmental-friendly synthesis strategy has been developed to form a pesticide and fertilizer combination to achieve the integration of plant protection and nutrient supply.

Superstretching MXene Composite Hydrogel as a Bidirectional Stress Response Thixotropic Sensor.

The arrival of the era of artificial intelligence is constantly advancing the development of flexible electronic materials. However, low mechanical properties, nonflexible signal transmission, and insensitive signal output have restricted their development as sensors. In this study, a superstretching MXene composite conductive hydrogel was developed with a tensile strain of more than 1800%.

A Convenient Ultraviolet Irradiation Technique for Synthesis of Antibacterial Ag-Pal Nanocomposite.

In the present work, palygorskite (Pal) was initially subjected to an ion-exchange reaction with silver ions (Pal-Ag(+)). Subsequently, Ag-Pal nanocomposites were assembled by a convenient ultraviolet irradiation technique, using carbon dots (CDs) derived from wool fiber as the reducing agent. The obtained nanocomposites were characterized by powder X-ray diffraction (XRD), ultraviolet-visible (UV-vis) spectroscopy, transmission electron microscopy (TEM), and Fourier transform infrared spectroscopy.

Safety reliability evaluation when vehicles turn right from urban major roads onto minor ones based on driver's visual perception.

Turning right has a significant impact on urban road traffic safety. Driving into the curve inappropriately or with improper turning speed often leads to a series of potential accidents and hidden dangers. For a long time, the design speed at intersections has been used to determine the physical radius of curbs and channelization, and drivers are expected to drive in accordance with the design speed.
