We begin with our knowledge of the structure and properties of atoms. We know that atoms have a nuclear structure, meaning that all of the positive charge and virtually all of the mass of the atom are concentrated in a nucleus which is a very small fraction of the volume of the atom.

Given the large number of possible configurations in polymers, what guides to likely properties are available? We have already seen some of the effects on properties of changing tacticity, for example, which can affect crystallinity.

While many university students take science courses in multiple disciplines, little is known about how they perceive common concepts from different disciplinary perspectives. Structure—property and structure—function relationships have long been considered important explanatory concepts in the disciplines of chemistry and biology, respectively. Fourteen university students concurrently enrolled in introductory chemistry and biology courses were interviewed to explore their perceptions regarding 1 the meaning of structure, properties, and function; 2 the presentation of these concepts in their courses; and 3 how these concepts might be related. Findings suggest that the concepts of structure and properties were interpreted similarly between chemistry and biology, but students more closely associated the discussion of structure—property relationships with their chemistry courses and structure—function with biology. Despite receiving little in the way of instructional support, nine students proposed a coherent conceptual relationship, indicating that structure determines properties, which determine function. Furthermore, students described ways in which they connected and benefited from their understanding. Though many students are prepared to make these connections, we would encourage instructors to engage in cross-disciplinary conversations to understand the shared goals and disciplinary distinctions regarding these important concepts in an effort to better support students unable to construct these connections for themselves.

Dietary Fiber: Chemistry, Structure, and Properties

In nature, water exists in the liquid, solid, and gaseous states. It is in dynamic equilibrium between the liquid and gas states at 0 degrees Celsius and 1 atm of pressure. At room temperature approximately 25 degrees Celsius , it is a tasteless, odorless, and colorless liquid. Many substances dissolve in water, and it is commonly referred to as the universal solvent. Similar to many other substances, water can take numerous forms. The solid phase of water is known as ice and commonly takes the structure of hard, amalgamated crystals, such as ice cubes, or of loosely accumulated granular crystals, such as snow.

Molecule , a group of two or more atoms that form the smallest identifiable unit into which a pure substance can be divided and still retain the composition and chemical properties of that substance. The division of a sample of a substance into progressively smaller parts produces no change in either its composition or its chemical properties until parts consisting of single molecules are reached. Further subdivision of the substance leads to still smaller parts that usually differ from the original substance in composition and always differ from it in chemical properties. In this latter stage of fragmentation the chemical bonds that hold the atoms together in the molecule are broken. Atoms consist of a single nucleus with a positive charge surrounded by a cloud of negatively charged electrons.

 Похож на китайца. Японец, подумал Беккер. - Бедняга. Сердечный приступ. Беккер безучастно кивнул: - Так мне сказали. Лейтенант вздохнул и сочувственно помотал головой.

 Самое разрушительное последствие - полное уничтожение всего банка данных, - продолжал Джабба, - но этот червь посложнее. Он стирает только те файлы, которые отвечают определенным параметрам. - Вы хотите сказать, что он не нападет на весь банк данных? - с надеждой спросил Бринкерхофф.  - Это ведь хорошо, правда.

В ней царила полная тишина. Прямо перед ним, откинувшись на груду старых подушек, лежал пожилой человек с ярко-белой гипсовой повязкой на правом запястье. ГЛАВА 21 Голос американца, звонившего Нуматаке по прямой линии, казался взволнованным: - Мистер Нуматака, в моем распоряжении не больше минуты. - Хорошо. Полагаю, вы получили обе копии ключа. - Вышла небольшая заминка, - сказал американец. - Это невозможно! - рявкнул Нуматака.

Он, конечно, понял, чем это грозит: червь сожрет фильтры, содержащие информацию в тайне, и без них она станет доступна всем без исключения. - Нам необходимо отключиться от Интернета, - продолжил Джабба.  - Приблизительно через час любой третьеклассник с модемом получит высший уровень допуска к американской секретной информации. Фонтейн погрузился в раздумья. Джабба терпеливо ждал, наконец не выдержал и крикнул ассистентке: - Соши.

 Забавно, - сказала.  - Последний файл из намеченных на вчера был загружен в одиннадцать сорок. - И .

Любое правительство выложит любые деньги. Можешь ли ты представить себе, как мы будем докладываем президенту, что перехватили сообщения иракцев, но не в состоянии их прочитать. И дело тут не только в АНБ, речь идет обо всем разведывательном сообществе. Наша машина обеспечивает информацией ФБР, ЦРУ, Агентство по борьбе с наркотиками - всем им теперь придется действовать вслепую.
