Single-atom catalysts (SACs) inherit the merit of both homogeneous and heterogeneous systems with atomically dispersed mononuclear metal centers on the solid supports. Herein, we developed an Ir-SAC catalyst via the polymerization of an active homogeneous 2-picolinylhydrazone ligand-based iridium (Ir) metal complex. Such catalysts provide great stabilization against migration and agglomeration due to the strong covalent C-C bond linkage of active complexes and the polymer matrix.

MXenes have excellent properties as electrode materials in energy storage devices or fuel cells. In bioelectrochemical systems (for wastewater treatment and energy harvesting), MXenes can have antimicrobial characteristics in some conditions. Here, different intercalation and delamination approaches to obtain TiCT MXene flakes with different terminal groups and lateral dimensions are comprehensively investigated.

Introduction: Ensuring optimal blood transfusion practices relies on a robust expertise base that is indispensable across various professional fields. Recognizing this imperative, the current study aims to assess the knowledge levels of healthcare personnel and enhance transfusion quality through targeted continuing training initiatives.

Methods: The preliminary survey was based on an anonymous questionnaire and we used correct response rate (CRR) as the main parameter evaluating the baseline level of knowledge.

Article Synopsis
  • Shortwave infrared (SWIR) light emitters and detectors are important for various applications but currently depend on expensive semiconductors like InGaAs, which are hard to integrate with existing silicon technology.
  • Colloidal quantum dots (CQDs) represent a cheaper alternative but often contain harmful heavy metals, which limits their use.
  • The study presents a new method to create InAs/ZnSe core/shell quantum dots that improve performance in the SWIR range, with high efficiency and low dark current, successfully demonstrating their use in photodetectors.

The international agriculture and food security sector is grappling with challenges like low crop yields, soil health deficiencies, and inefficient agrochemical use. The application of smart nanotechnology in agriculture, particularly surface functionalization, holds promise but has limited implementation. Engineered nanomaterials used as seed treatments, known as nanopriming, offer a simple technology to improve crop yield and stress tolerance.
