comes in to play where recycle bins and signage on every office floor is required to establish recycling. The purchasing of the bins will be essential to the campaign. There would be three recycling bins comprising of bins for Paper‚ Plastic and Aluminium Cans and will come in three different colours and stickers with a logo will be stuck on it to allow segregation of the recyclables. In addition to that‚ signage will be placed to direct users to the recycling bins. These collected recyclables will

Electrolysis Electrolysis is the process by which ionic substances are broken down into simpler substances using electricity. During electrolysis‚ metals and gases may form at the electrodes. What is electrolysis? Ionic substances contain charged particles called ions. For example‚ lead bromide contains positively charged lead ions and negatively charged bromide ions. Electrolysis is the process by which ionic substances are decomposed (broken down) into simpler substances when an electric

Introduction Metallic yarns or threads‚ in general‚ have been known for more than 3000 years. Gold and silver were hammered into extremely thin sheets‚ then cut into ribbons and worked into fabrics. These were the first ‘man made’ fibres‚ which came thousands of years before nylon or rayon. The Persians made fabulous carpets with gold thread and the Indians‚ ornamental sarees with it. The metal threads were twisted‚ doubled or wrapped around some other thread such as cotton. With the advancement

During the experiment‚ aluminium and mild steel was used to demonstrate how the materials behave during the testing condition. By measuring the applied torque with respect to the angle of twist‚ the Torsional rigidity (GJ)‚ the Modulus of Rigidity (G) and the shear yield stress (τ) for ductile materials‚ mild steel and aluminium. INTRODUCTION The purpose of this experiment is to study and to compare the behaviour of ductile

Al-B4C composites. Attempts were made to overcome the wetting problem between B4C and liquid aluminium at lower temperatures for promising the mechanical and tribological behaviour of the Al -B4C composites. AA6061-B4C particle reinforced composites were produced through casting route at 850ºC with K2TiF6 added as flux to overcome the wetting problem between B4C and liquid aluminium metal. The Aluminium B4C composite samples were subsequently subjected to T6 heat treatment. The composite samples

The Vickers number of hardness for cold rolled specimens can be show very clearly that it has increasing up the number itself likewise the number of thickness reduction which also increasing. Which its number of Vickers can be rated as follow as Aluminium < Copper < Brass ; this means that Brass has the most tensile strength‚ Aluminium is easily to bend and
