Here we describe the electroless deposition of Cu-Ag alloys in deep eutectic solvents using a variety of electrochemical and surface analysis techniques to determine the mechanism of alloy deposition and composition of deposits. The influence of various conditions on electroless deposition and the morphology of the deposit layers have been investigated by scanning electron microscopy (SEM) with energy dispersive analysis by X-rays (EDX). The electrochemical behaviour of pure copper, pure silver and Cu-Ag alloys was studied at various working electrodes by cyclic voltammetry. The use of (EQCM) electrochemical quartz crystal microbalance is shown to be very dependent upon the concentration of ions in solution. the cathodic current efficiency for the deposition of Cu-Ag alloys is about 99%.

Many classrooms utilize discussion boards to aid the teaching and learning process. This research paper examines the use of the discussion board academically and on a social scale. It is a case study analysing the incorporationof two Viber discussion boardsamongsttwo professional development courses designed for pre-service and in-service teachers of Libyan schools. The aim is to use the discussionboard as a means of exchanging ideas, requesting explanations, and inquiring information from trainees and their instructors. The data collected is analyzed qualitatively using content analysis, then coded into three initial coding schemes. A questionnaire was also distributed amongst the members of the discussion boards. The findings bring to light that utilizing discussion boards as a method of collaboration enhances the communication process amongst the participants and strengthens the educational process. It furthermore displayed the crucial role an instructor plays in a discussion board.
