REVIEW doi:10.1038/nature10676 Multigate transistors as the future of classical metal–oxide–semiconductor field-effect transistors Isabelle Ferain1‚ Cynthia A. Colinge1 & Jean-Pierre Colinge1 For more than four decades‚ transistors have been shrinking exponentially in size‚ and therefore the number of transistors in a single microelectronic chip has been increasing exponentially. Such an increase in packing density was made possible by continually shrinking the metal–oxide–semiconductor

slowly and observe the reaction. Next‚ place a burning splint near the mouth of the test tube to test for the presence of hydrogen gas. 4. Electrolysis of water Use a U-tube with electrodes at each end‚ connected to a battery. Fill the U-tube with water. Turning on the battery‚ observe the results at each electrode. Next‚ test for hydrogen and oxygen gas produced at each end of the tube. 5. Burning magnesium Place magnesium ribbon in a clean crucible (on a clay triangle above a Bunsen burner)

6. TREATMENT METHODS Screening‚ grit removal‚ flow equalization‚ sedimentation‚ or dissolved air flotation are used to reduce suspended solids (SS) load from sugar industry wastewater. Biological treatment includes aerobic and anaerobic process. Except biological methods‚ physico-chemical methods are also used for sugar industry wastewater treatment. 6.1 Biological methods Since‚ sugar industry wastewater contains mostly sugars and volatile fatty acids‚ which are easily biodegradable‚ therefore all
