Optical methods of antibiotic residues detections: A comprehensive review

Abstract: This review paper presents the achievements and developments in the optical methods of antibiotic residues detection. The specific optical methods such as optical immunoassay methods, molecular spectroscopy detection methods, and optical fiber based detection methods are summarized in detail. And each of them was summarized and contrasted in a separate table, where the sensing structure, class of antibiotics and the limit of detection are all listed. Optical methods of antibiotic detections are widely used during the last two decades due to their short detection cycles, high sensitivity and simple operation, which are mainly researched for the food and water quality inspections. The future direction of sensing performances and application fields is also discussed.

Measurement of resilience and its application to enterprise information systems

Abstract: In this article, we present a measure for resilience in the context of enterprise information systems or service systems in a more general sense. Resilience of the system is a property of the system, which focuses on the recovery ability of the system after a partial damage of the system. Enterprise information systems such as enterprise resource planning, supply chain management, customer relationship management, manufacturing execution system, etc. play a critical role in the daily operation of modern enterprises by timely and sustainable delivery of information. Therefore, resilience is especially important for the enterprise information systems. The proposed measure for resilience is based on the recovery ability of the system, which departs from the existing approaches in literature and presents a unique contribution. An example is given to illustrate how the proposed measure works.

Electrochemical Codeposition of Vanadium Oxide and Polypyrrole for High-Performance Supercapacitor with High Working Voltage

Abstract: Electrochemical codeposition of vanadium oxide (V2O5) and polypyrrole (PPy) is conducted from vanadyl sulfate (VOSO4) and pyrrole in their aqueous solution to get V2O5–PPy composite, during which one-dimensional growth of polypyrrole (PPy) is directed. X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR) are used to characterize the composite, while scanning electron microscopy (SEM) is used to investigate their morphologies. Cyclic voltammetry (CV), chronopotentiometry (CP) for galvanostatic charge–discharge and electrochemical impedance spectroscopy (EIS) are used to study electrochemical activities and pseudocapacitive properties of the composite. The influences of VOSO4 to pyrrole ratio in the electro-codeposition solution on morphologies and pseudocapacitive properties of the composite are discussed. Due to the organic–inorganic synergistic effect, V2O5–PPy composite exhibits good charge-storage properties in a large potential window from −1.4 to 0.6 V vs SCE, with a specific c...
