As the electron transport layer in quantum dot light‐emitting diodes (QLEDs), ZnO suffers from excessive electrons that lead to luminescence quenching of the quantum dots (QDs) and charge‐imbalance in QLEDs. Therefore, the interplay between ZnO and QDs requires an in‐depth understanding. In this study, DFT and COSMOSL simulations are employed to investigate the effect of sulfur atoms on ZnO. Based...
Tin‐lead (Sn‐Pb) mixed perovskites is beneficial to a single‐junction or all‐perovskite tandem device. However, the poor quality of the perovskite surface resulting from Sn2+ oxidation and uncontrollable crystallization degrades device performance and stability. Herein, based on interface engineering, a novel biguanide derivative of PZBGACl is employed that integrates different types of N‐related...
Power generation from water‐triggered capillary action in porous structures has recently geared extensive attention, offering the potential for generating electricity from ubiquitous water evaporation. However, conclusively establishing the nature of electrical generation and charge transfer is extremely challenging arising from the complicated aqueous solid–liquid interfacial phenomenon. Here, an...
Non‐noble metal catalysts are known for their efficient catalytic performance for oxygen reduction reaction (ORR), oxygen evolution reaction (OER), and hydrogen evolution reaction (HER). Metal organic gels (MOGs) can be considered as a promising electrocatalyst owing to the diverse physicochemical properties but usually suffer from its poor electrical conductivity and catalytic stability. Here, a...
Normally, only noncentrosymmetric structure of the materials can potentially be piezoelectric. Thus, it is limited in the field of piezoelectricity for the centrosymmetric structure of the material. In this work, the performance of piezoelectricity is successfully achieved from centrosymmetric SrFeO3‐x by modulating oxygen vacancies, which have a surface piezoelectric potential up to 93 mV by using...
Multifunction superhydrophobic coatings that facilitate water harvesting are attractive for addressing the daunting water crisis, yet, they are caught in a double bind when their durability is considered, as durable coatings will require both tough micro‐textures to survive concentrated stress and high‐surface‐energy chemistry to form chemical bonds within the matrix. To date, a universal bulk‐phase...
Breast cancer (BC) is a major global health problem, with ≈20–25% of patients overexpressing human epidermal growth factor receptor 2 (HER2), an aggressive marker, yet access to early detection and treatment varies across countries. A low‐cost, equipment‐free, and easy‐to‐use polydiacetylene (PDA)‐based colorimetric sensor is developed for HER2‐overexpressing cancer detection, designed for use in...
The pursuit of stable and efficient electrocatalysts toward seawater oxidation is of great interest, yet it poses considerable challenges. Herein, the utilization of Cr‐doped CoFe‐layered double hydroxide nanosheet array is reported on nickel‐foam (Cr‐CoFe‐LDH/NF) as an efficient electrocatalyst for oxygen evolution reaction in alkaline seawater. The Cr‐CoFe‐LDH/NF catalyst can achieve current densities...
Reducing the dark current of photodetectors is an important strategy for enhancing the detection sensitivity, but hampered by the manufacturing cost due to the need for controlling the complex material composition and processing intricate interface.
