  • The heroine of this book is nature’s simplest atom, the hydrogen atom. With one exception—the helium atom—hydrogen is the mother of all atoms and molecules. The hydrogen atom consists of a single electron and a single proton; the proton is the nucleus of the hydrogen atom and serves as the electron’s anchor. The universe is teeming with hydrogen: every cubic centimeter of dark interstellar space, essentially void of any other known matter,1 contains a few atoms of hydrogen

  • The Baltic Sea is a unique basin, being productive with intensive fishing potential and has therefore been the object of many studies. It is a brackish, nontidal, relatively shallow and semi-enclosed sea. The Baltic is located at a high latitude, hence one of its characteristic features is ice. Another unique geographical pattern are the archipelagos located off the coast of Stockholm which consist of more than 25 000 islands. The relative ionic concentration of toxic substances e.g. chemical elements is generally higher in the low-saline Baltic Sea than compared to the North Sea....

  • In this research, three-component-oxide CaO-CuO-CeO2 was fabricated a sol-gel method. This mixed oxide acted as the catalysts for the complete oxidation of phenol in the presence of hydro peroxide. The activity of the catalyst was monitored versus fabrication conditions of mixed oxide such as aging temperature, calcination temperature and time. Under the optimum conditions including aging temperature at 70 oC, calcination at 600 oC for 30 min, the catalyst gave the best activity with 96.3% phenol conversion.

  • Metallic fuel has been considered for sodium-cooled fast reactors because it can maximize the uranium resources. It generates rare earth elements as fission products, where it is reported by aggravating the fuelecladding chemical interaction at the operating temperature. Rare earth elements form a multicomponent alloy (CeeNdePreLaeSmeetc.) during reactor operation, where it shows a higher reaction thickness than a single element.

  • Chemical substances (also called pure substances) may well be defined as "any material with a definite chemical composition" in an introductory general chemistry textbook.[2] According to this definition a chemical substance can either be a pure chemical element or a pure chemical compound. But, there are exceptions to this definition; a pure substance can also be defined as a form of matter that has both definite composition and distinct properties.[3] The chemical substance index published by CAS also includes several alloys of uncertain composition.

  • Water is one of the basic elements for life. It is even assumed that the evolution of life is only possible if there is liquid water present. A water molecule has some remarkable properties that make it quite unique in the universe. In the first chapter of this book we will review these basic properties of water and the role of water on Earth. All ancient civilizations realized the importance of water and their cities were constructed near great reservoirs of water.

  • Almost any land contains enough food for the growing of good crops, but the food elements may be chemically unavailable, or there may be insufficient water to dissolve them. It is too long a story to explain at this place,--the philosophy of tillage and of enriching the land,--and the reader who desires to make excursions into this delightful subject should consult King on "The Soil," Roberts on "The Fertility of the Land," and recent writings of many kinds. The reader must accept my word for it that tilling the land renders it productive. I must call my reader's attention...

  • January 2012 saw the completion of the U.S. Army’s Chemical Materials Agency’s (CMA’s) task to destroy 90 percent of the nation’s stockpile of chemical weapons. CMA completed destruction of the chemical agents and associated munitions stored at six of eight continental U.S. storage facilities as well as chemical weapons deployed overseas, which were transported to Johnston Atoll, southwest of Hawaii, and demilitarized there. The remaining 10 percent of the nation’s chemical weapons stockpile is stored at two remaining continental U.S. depots, in Lexington, Kentucky, and Pueblo, Colorado.
