Evaluation of Groundwater in the Coastal Portion of Guasave, Sinaloa for White Shrimp Farming (Penaeus vannamei) through VES, Chemical Composition, and Survival Tests

Journal of Marine Science and Engineering, 2021
We studied the potential of white shrimp farming with groundwater from the coastal aquifer of Guasave, Sinaloa. The use of water from the aquifer in aquaculture represents challenges due to variability in the quality of groundwater.

High Temperature Oxidized SnO2 Films Prepared by Reactive Sputtering

Active and Passive Electronic Components, 1987
Undoped and Sb-doped tin oxide films were prepared by d.c. reactive ion sputtering in an argon atmosphere with oxygen partial pressures ranging from 0 to 50%. The films were anneled in oxygen in the temperature range 360 - 893℃.

Anisotropy of the In-Plane and Out-of-Plane Resistivity and the Hall Effect in the Normal State of Vicinal-Grown YBa₂Cu₃O_7−δ Thin Films

Nanomaterials, 2021
The resistivity and the Hall effect in the copper-oxide high-temperature superconductor YBa2Cu3O7-δ (YBCO) are remarkably anisotropic. Using a thin film of YBCO grown on an off-axis cut SrTiO3 substrate allows one to investigate these anisotropic ...

Area Selective Deposition of Metals from the Electrical Resistivity of the Substrate

, 2021
Area selective deposition (ASD) of films only on desired areas of the substrate opens for less complex fabrication of nanoscaled electronics. We show that a newly developed CVD method, where plasma electrons are used as the reducing agent in deposition ...
