Comparative study of hydrogen sensing characteristics of a Pd/GaN Schottky diode in air and N2 atmospheres

Preparation and utilization of wheat straw bearing amine groups for the sorption of acid and reactive dyes from aqueous solutions

“…It is probable, therefore, that this sorption system is not a firstorder reaction, it fits the pseudo-second order. Similar results were reported for the sorption of basic red 22 onto pith [36].…”

“…The Langmuir isotherm was applied to calculate the thermodynamic parameters via Eqs. (8) and (9) [35,36]:…”

Preparation, characterization of wheat residue based anion exchangers and its utilization for the phosphate removal from aqueous solution

“…The Langmuir isotherm was applied to calculate the thermodynamic parameters via Eqs. (4) and (5) (Huang, Hu, Chen, & Liu, 2007;Renbutsu et al, 2007):…”

The electrodeposition, magnetic and electrical characterisation of Palladium–Nickel alloys

“…The chips were washed with Acetone and Isopropylalcohol (IPA), blown dry and coated with an electrically inert varnish to prevent electrodeposition in all areas except a 1 cm  0. 5 DI water. The chip was immediately immersed in the bath and electrodeposition was performed at room temperature using an Autolab PGSTAT30 system with a calomel reference electrode and Pt mesh as the counter electrode.…”

“…Sahoo et al [4] formed ferromagnetic PdNi contacts to Carbon nanotubes (CNTs) to study their spintronic properties. Pure Pd [5,6] and PdNi [7] films have also been used to fabricate Hydrogen sensors by exploiting the change in electrical properties of Palladium upon absorption of gaseous Hydrogen. Pure Pd exhibits an irreversible phase change after absorption of a certain amount of gaseous Hydrogen and the addition of Ni can stabilise the sensor over a wider range of Hydrogen pressures by delaying this change.…”
