  2. 1. On the Low Frequency Noise in Ion Sensing

    Author : Da Zhang; Zhen Zhang; Shili Zhang; Hans Norström; Jörgen Olsson; Michel Calame; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; low frequency noise; ion sensor; ISFET; electrochemical impedance spectroscopy; constant phase element; surface chemistry; CMOS technology; Engineering Science; Teknisk fysik;

    Abstract : Ion sensing represents a grand research challenge. It finds a vast variety of applications in, e.g., gas sensing for domestic gases and ion detection in electrolytes for chemical-biological-medical monitoring. READ MORE

  4. 2. Instability in Settling Fibres : A Numerical Study

    Author : Feng Zhang; Anders A. Dahlkild; Fredrik Lundell; Mark Martinez; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bre suspensions; sedimentation; instability; mixture model; point-particle mode;

    Abstract : Sedimenting suspensions exist in a varity of natural phenomena and industrial applications. It is already observed in experiments that the dilute fibre suspensions experience a concentration instability under gravity at low Reynolds numbers. Initially well-mixed suspensions become inhomogeneous and anisotropic due to this instability. READ MORE

  5. 3. Aqueous graphene dispersions for paper packaging

    Author : Wei Zhao; Anwar Ahniyaz; Abhilash Sugunan; Thomas Gillgren; Johan A. Larsson; Zhi-Bin Zhang; Shi-Li Zhang; Valeria Nicolosi; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Graphene; Aqueous graphene dispersions; Noncovalent interactions; Composites; Barriers; Inkjet printing; Kemi med inriktning mot kemisk fysik; Chemistry with specialization in Chemical Physics;

    Abstract : Graphene is widely touted as the thinnest and the most versatile material available. As an atomically thin layer of carbon atoms arranged in a hexagonal configuration, graphene has a combination of technologically important properties, such as thermal and electrical conductivity, mechanical strength, and impermeability to gases.

  6. 4. Biomarkers for Diagnosis, Therapy and Prognosis in Colorectal Cancer : a study from databases, machine learning predictions to laboratory confirmations

    Author : Xueli Zhang; Hong Zhang; Xiao-Feng Sun; Dirk Repsilber; Bairong Shen; Mauno Vihinen; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomarkers; diagnosis; therapy response; prognosis; database; machine learning; CRC;

    Abstract : Colorectal cancer (CRC) is one of the leading causes of cancer death worldwide. Early diagnosis and better therapy response have been believed to be associated with better prognosis. CRC biomarkers are considered as precise indicators for the early diagnosis and better therapy response. READ MORE

  7. 5. Thermodynamic Analysis and Screening ILs/DESs-based Absorbents for CO2 Separation

    Author : Yingying Zhang; Xiangping Zhang; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : CO2 separation plays an important role in both biofuel production, and CO2 capture and storage (CCS) implementation to deal with global warming. The available CO2 separation technologies are either energy-intensive or require large-scale operations, and it is crucial to develop novel CO2 separation technology in order to optimize the energy uses and the amounts of CO2-absorbents/adsorbents.
