We numerically analyze the interaction of small-amplitude phonon waves with standing gap discrete breather (DB) in strained graphene. To make the system support gap DB, strain is applied to create a gap in the phonon ...

A novel solid-phase microextraction technique using a hollow fiber-supported sol–gel combined withmulti-walled carbon nanotubes was employed in the determination of phenobarbital in wastewater. In this new technique, a silica-based, organic...

By calculating the accurate solution of the governing differential equation for a non-prismatic beam–column, the exact elemental stiffness matrix will be obtained. The Euler–Bernoulli beam theory is used in the ...

solid sate sensor for determination of codeine in various samples.

This work is considered a simple PVC based potentiometric ion selective electrode

based on the codeinium–tetrapheylborate ion pair as sensing material which is coated...
