Karakterisasi Superkonduktor Bahan Bscco Didoping Dengan MgO

Nitrite Content of Some Foods in Malaysia

Nitrat and nitrit adalah bahan tambah yang biasa digunakan dalam pengkiuran daging. Bahan-bahan ini juga memberi warna dan perisa yang baik dan dapat merencat penumbuhan mikroorganisma Clostridium botulinum. Nitrit boleh bertindak dengan amina sekunder dan membentuk sebatian nitrosamina. Nitrosamina inilah yang menjadi satu kontroversi berhubung dengan penggunaan nitrit kerana nitrosamine ini m...

Theoretical Considerations for Viscoelastic Characterization of Biomaterials

Untuk sesuatu rekaan, pembinaan serta ujian jentera-jmtera memproses dan mesin-mesin pengangkutan bahan-bahan biological, sifat-sifat mekanikal bahan-bahan tersebut perlu diketahui terlebeh dahulu. Oleh kerana percubaan-percubaan yang lampau dapat mempastikan bahawa bahan-bahan biological bersifat viscoelastic, perlulah ianya dinyatakan supaya dapat dipastikan tindak balas sifat-sifat tersebut ...

Shapiro Steps in BSCCO Intrinsic Josephson Junctions

Intrinsic c - Axis Transport in 2212 - BSCCO

We describe two experimental approaches to circumvent the problem of self-heating in IV measurements on small mesa samples of 2212-BSCCO. Simultaneous dc and temperature measurements have been performed, allowing corrections for heating to be made. Short pulse measurements have also been made, where the IV characteristics and the mesa temperature can be measured on a µs timescale enabling intri...

Intrinsic C-Axis Tunnelling in BSCCO Crystals

Intrinsic c-axis tunnelling in the superconducting state has been measured in zero and finite fields in small mesa structures fabricated on the surface of 2212-BSCCO single crystals. The temperature dependence of the zero-field critical current and quasi-particle conductance is related to microscopic d-wave models in the presence of impurity scattering. The strong field dependence of the c-axis...
