High-isolation BST-MEMS switches
2002 IEEE MTT-S International Microwave Symposium Digest (Cat. No.02CH37278), 2003In this paper, emerging (Ba,Sr)TiO/sub 3/ thin film technology was investigated for enhancing RF-MEMS capacitive switches. Materials properties of high-permittivity BST thin films and fabrication issues are discussed. Prototype BST-MEMS switches for K-/Ka-band applications were fabricated and measured.

High-isolation metamaterial MIMO antenna
2017 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting, 2017This paper presents the design of a metamaterial MIMO antenna which operates at 5.8 GHz. The left handed single cell of series capacitor and shunt inductor are considered the main block of the antenna elements. The configuration of the shunt stub is reversed to achieve lower coupling between the antenna elements The small size of only 2.93cm×2.6cm and ...

High Pressure Homogenization for Inclusion Body Isolation
2023High pressure homogenization (HPH) is a commonly used method for cell lysis of Escherichia coli in order to release intracellularly produced recombinant proteins. For misfolded proteins in E. coli, focus is often put on the development of a suitable solubilization and refolding protocol.

High isolation MIMO antenna for high speed communication
2014 USNC-URSI Radio Science Meeting (Joint with AP-S Symposium), 2014Ubiquitous use of handheld devices has put a tremendous strain on the available bandwidth of communication. The scarcity of spectrum has rapidly shifted the modern systems towards multiple input and multiple output systems (MIMO). The development of MIMO antennas has attracted significant attention in literature.

High efficient, high density isolated DC-DC converter
2017 International Conference on Innovations in Electrical, Electronics, Instrumentation and Media Technology (ICEEIMT), 2017This paper discusses the design and analysis of a 380/12 V DC-DC high efficient LLC converter having a power output of 750W. The ripple in output voltage is brought down to 0.09V. It works with an efficiency of 96.1 percent at full load, 97.2 percent efficiency at 50 percent load and 91.2 percent efficiency at 10 percent load.

High Voltage Single Column Isolators
IEEE Transactions on Power Apparatus and Systems, 1972The increase in number and size of outdoor switchgear installations up to the highest service voltages has led to the development of a new single column isolator of the pantograph design. This paper describes the design and operation as well as the tests to which this isolator was subjected.

Isolation of high quality RNA from Streptomyces
Journal of Microbiological Methods, 2004Several molecular techniques require high quality RNA, completely free of DNA. Standard methods to isolate total RNA from Streptomyces spp. are based on the application of a 'Modified Kirby Mix' [Practical Streptomyces Genetics. The John Innes Foundation, Norwich, pp. 613].
