Student Senate Enrolled Legislation

A BILL

To appropriate one thousand five hundred dollars ($1500.00) to the LSU Department of Mechanical Engineering Senior Project Team to help defray the cost of purchasing hardware to be used in the fabrication of a solar powered boat that will be in competition in the Solar Splash Regatta in New Orleans, Louisiana.

Cable Steering System, David A. Renfroe, Joseph F. Partain

Patents Granted

Describes a steering system in an all-terrain four-wheeled vehicle with independent suspension where the necessary forces for steering control are supplied by cable and pulley actuators with the cable running parallel to the suspension arm between vehicle frame and wheel, steering control by the driver is by manipulation of right and/or left steering levers eliminating the need of steering wheel and steering column in front of the driver. The steering actuators are independent and there is no linkage for coordinating their turning angles. Close coordination of the wheel turning angles for achieving the turning angle relation between the wheels is …

Oxygen Permeation Through Composite Oxide-Ion And Electronic Conductors, Kevin Huang, Michael Schroeder, John B. Goodenough

Faculty Publications

Oxygen permeation through composites consisting of four well-known oxide-ion conductors and a noble metal, Pd or Ag, is reported. The oxides were Zr_0.9Y_0.1O_1.95 (YSZ), (Bi_1.75Y_0.25O₃)_0.95(CeO₂)_0.05 (BYC5), Ce_0.8Sm_0.2O_1.9 (SSC), and La_0.8Sr_0.2Ga_0.83Mg_0.17O_2.815 (LSGM). The results show that (BYC5 + Ag) yields the highest oxygen permeation flux, but the composite deteriorates with time. The composites (SSC + Pd), (LSGM + Pd), and (YSZ + Pd) give stable, but relatively lower oxygen permeation flux …

Method Of Electroplating A Substrate, And Products Made Thereby, John H. Glezen, Hameed A. Naseem, William D. Brown, Leonard W. Schaper, Ajay P. Malshe

Patents Granted

Disclosed is an electroplating method and products made therefrom, which in one embodiment includes using a current density to form a conductive metal layer having a surface roughness no greater than the surface roughness of the underlying member. In another embodiment of electroplating a substrate surface having peaks and valleys, the method includes electroplating a conductive metal onto the peaks to cover the peaks with the conductive metal, and into the valleys to substantially fill the valleys with the conductive metal.
