In-situ signal amplification of microneedles in a transistor for allergy molecular detection.

The rapid and accurate detection of histamine is of great significance for the early diagnosis and precise treatment of allergic diseases. Traditional histamine detection usually is more invasive and limited for the detection of allergic reactions in local areas. In this work, microneedles (MNs) enable of in-situ transdermal detection are employed as the extended gate of the thin-film transistor (TFT).

Solution-processed high- photopatternable polymers for low-voltage electronics.

High dielectric constant () polymers have been widely explored for flexible, low-power-consumption electronic devices. In this work, solution-processable high- polymers were designed and synthesized by ultraviolet (UV) triggered crosslinking at a low temperature (60 °C). The highly crosslinked network allows for high resistance to organic solvents and high breakdown strength over 2 MV cm.

CN: A Class of Covalent Frameworks with Unique Properties.

CN is a unique member of the CN family (carbon nitrides), i.e., having a covalent structure that is ideally composed of carbon and nitrogen with only 33 mol% of nitrogen.

Efficient and Stable Planar n-i-p SbSe Solar Cells Enabled by Oriented 1D Trigonal Selenium Structures.

Environmentally benign and potentially cost-effective SbSe solar cells have drawn much attention by continuously achieving new efficiency records. This article reports a compatible strategy to enhance the efficiency of planar n-i-p SbSe solar cells through SbSe surface modification and an architecture with oriented 1D van der Waals material, trigonal selenium (t-Se). A seed layer assisted successive close spaced sublimation (CSS) is developed to fabricate highly crystalline SbSe absorbers.

A Generalized Crystallization Protocol for Scalable Deposition of High-Quality Perovskite Thin Films for Photovoltaic Applications.

Metal halide perovskite solar cells (PSCs) have raised considerable scientific interest due to their high cost-efficiency potential for photovoltaic solar energy conversion. As PSCs already are meeting the efficiency requirements for renewable power generation, more attention is given to further technological barriers as environmental stability and reliability. However, the most major obstacle limiting commercialization of PSCs is the lack of a reliable and scalable process for thin film production.
