  1. 1. On Neutrophil and Platelet Adhesive Interactions in Septic Lung Injury

    Author : Asad Muhammad; Kirurgi; []
    Keywords : Leukocytes; chemokines; platelets; lung; sepsis;

    Abstract : Sepsis induced by intestinal perforation is a life-threatening illness and is a frequent cause of leukocyte-mediated lung injury. Although antimicrobial therapy has been the central clinical strategy for these patients, the survival rates in such patients are still very low because of their impaired host defense mechanisms.

  2. 2. Graphene field-effect transistors for high frequency applications

    Author : Muhammad Asad; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; high frequency; Graphene; transit frequency; transconductance; maximum frequency of oscillation; contact resistance; microwave electronics; field-effect transistors;

    Abstract : Rapid development of wireless and internet communications requires development of new generation high frequency electronics based on new device concepts and new materials. The very high intrinsic velocity of charge carriers in graphene makes it promising new channel material for high frequency electronics. READ MORE

  3. 3. Impact of adjacent dielectrics on the high-frequency performance of graphene field-effect transistors

    Author : Muhammad Asad; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; contact resistance; transit frequency; field-effect transistors; drift velocity; saturation velocity; diamond; high-frequency electronics; Graphene; maximum frequency of oscillation;

    Abstract : Transistors operating at high frequencies are the basic building blocks of millimeter wave communication and sensor systems. The high velocity and mobility of carriers in graphene can open ways for development of ultra-fast group IV transistors with similar or even better performance than that achieved with III-V based semiconductors.
