1 Class XII Chemistry Ch 5: Surface Chemistry Chapter Notes Top Concepts / Key learnings: 1. 2. 3. 4. 5. 6. Adsorption: The accumulation of molecular species at the surface rather than in the bulk of a solid or liquid is termed as adsorption. Adsorbate: The substance which is being adsorbed on the surface of another substance is called adsorbate. Adsorbent: The substance present in bulk‚ on the surface of which adsorption is taking place is called adsorbent. Desorption: The process of removing an

NANOTECHNOLOGY What is NANO TECHNOLOGY? Nanotechnology is science‚ engineering‚ and technology conducted at the nanoscale‚ which is about 1 to 100 nanometers. Nanoscience and nanotechnology are the study and application of extremely small things and can be used across all the other science fields‚ such as chemistry‚ biology‚ physics‚ materials science‚ and engineering. Nanotechnology is not just a new field of science and engineering‚ but a new way of looking at and studying .

is also high at 12.4 mg/dL when compared to the normal value of 8.5-10.2 mg/dL. All three of these test results lead to the diagnosis‚ kidney dysfunction. Kidney dysfunction occurs because the glomerulus within the kidney responsible for the ultrafiltration of blood‚ excrete the large numbers of monoclonal antibodies into the proximal tubules which results in the proteinuria. However‚ such large volumes of antibodies within these tubules detrimentally affect the proximal tubules to catabolize proteins

O&M costs) treatment e.g. membrane filtration. 15 years ago reverse osmosis (RO) became state-of-the-art for the production of demineralised water (boiler feed or process water) from conventionally pretreated surface water. Recently direct ultrafiltration (UF) of those surface water without any pretreatment except a common screen filter has become a suited solution for direct production of pure water (e.g. potable water) or as an efficient pretreatment in combination with RO.

Mangroves are various kinds of trees up to medium height and shrubs that grow in salinecoastal sediment habitats in the tropics and subtropics – mainly between latitudes 25° N and 25° S. The remaining mangrove forest areas of the world in 2000 was 53‚190 square miles (137‚760 km²) spanning 118 countries and territories.[1][2] The word is used in at least three senses: (1) most broadly to refer to the habitat and entire plant assemblage ormangal‚[3][page needed] for which the terms mangrove forest biome

Risks associated with endotoxins Occupational exposure to endotoxins poses a threat to employees that are situated in a broad range of workplaces. More specifically‚ places of work that deal directly with organic materials. Such areas include the grain and seed sector‚ horticulture and the livestock processing sector. An investigation carried out on the grain and seed sector in the Netherlands showed that the presence of endotoxin coupled with the substantial inhalable dust fraction could adversely

Practical 2: Observation of mammalian kidney model and tissue slides. Analyzing kidney filtration using simple filtration system Introduction: Kidney is part of mammalian’s body endocrine system. Every mammals have a pair of kidneys that is located at the middle back of the body and symmetrically beside the spine and below the rib cage. A kidney approximately 0.5% of the organism body weight. Every kidney will receive huge amount of blood to enable them to perform important task. The base unit of

Industry Visit – NeWater Plant An industry visit to Changi NeWater plant took place on 22nd February 2013 under the supervision of Amity faculty‚ Aditya Gupta. It was for a duration of 3 hours and our guide in NeWater was Sharul Mustafa. The guide gave a brief history about Singapore and the reasons why this plant was started. It was a very informative and enriching experience that helped us in understanding the value of nature and optimizing use of limited resources. As a souvenir a bottle of NeWater

Use of Enzymes in Food Industry - Food industry utilizes a variety of enzymes for processing of various foods‚ e.g.‚ production of various types of syrups from starch or sucrose (a- and β- amylases‚ glucamylase‚ pullulanase‚ invertase‚ and glucose isomerase)‚ meat/protein processing using proteases‚ removal of glucose and or molecular oxygen (O2) using glucose oxidase and catalase‚ use of lactase in dairy industry and use of enzymes in fruit juice and brewing industries. Glucose oxides are obtained

How to Remove Heavy Metal Toxins with Oral Chelation Do you currently have heavy metal toxins damaging the inside of your body? The answer is unfortunately "yes" for over 99% of us! So what is a “heavy metal” and what do I need to know? If you’re thinking of Ozzy Osbourne‚ KISS‚ or Ted Nugent‚ you’re not alone. The truth is that most people do not fully understand the real dangers of heavy metal poisons and just how common they are in our modern world. Fortunately‚ you can take steps to understand
