Radical (chemistry)
In chemistry, a radical, also known as a free radical, is an atom, molecule, or ion that has at least one unpaired valence electron. With some exceptions, these unpaired electrons make radicals highly chemically reactive. Many radicals spontaneously dimerize. Most organic radicals have short lifetimes. A notable example of a radical is the hydroxyl radical (HO·), a molecule that has one unpaired electron on the oxygen atom. Two other examples are triplet oxygen and triplet carbene (꞉) which have two unpaired electrons. Radicals may be generated in a number of ways, but typical methods involve redox reactions. Ionizing radiation, heat, electrical discharges, and electrolysis are known to produce radicals. Radicals are intermediates in many chemical reactions, more so than is apparent from the balanced equations. Radicals are important in combustion, atmospheric chemistry, polymerization, plasma chemistry, biochemistry, and many other chemical processes. A majority of ...

Biweekly Journals
A weekly newspaper is a general-news or current affairs publication that is issued once or twice a week in a wide variety broadsheet, magazine, and digital formats. Similarly, a biweekly newspaper is published once every two weeks. Weekly newspapers tend to have smaller circulations than daily newspapers, and often cover smaller territories, such as one or more smaller towns, a rural county, or a few neighborhoods in a large city. Frequently, weeklies cover local news and engage in community journalism. Most weekly newspapers follow a similar format as daily newspapers (i.e., news, sports, obituaries, etc.). However, the primary focus is on news within a coverage area. The publication dates of weekly newspapers in North America vary, but often they come out in the middle of the week (Wednesday or Thursday). However, in the United Kingdom where they come out on Sundays, the weeklies which are called ''Sunday newspapers'', are often national in scope and have substantial circul ...

Biochemistry Journals
Biochemistry or biological chemistry is the study of chemical processes within and relating to living organisms. A sub-discipline of both chemistry and biology, biochemistry may be divided into three fields: structural biology, enzymology and metabolism. Over the last decades of the 20th century, biochemistry has become successful at explaining living processes through these three disciplines. Almost all areas of the life sciences are being uncovered and developed through biochemical methodology and research. Voet (2005), p. 3. Biochemistry focuses on understanding the chemical basis which allows biological molecules to give rise to the processes that occur within living cells and between cells,Karp (2009), p. 2. in turn relating greatly to the understanding of tissues and organs, as well as organism structure and function.Miller (2012). p. 62. Biochemistry is closely related to molecular biology, which is the study of the molecular mechanisms of biological phenomena.Ast ...

Toxicology Abstracts
Toxicology is a scientific discipline, overlapping with biology, chemistry, pharmacology, and medicine, that involves the study of the adverse effects of chemical substances on living organisms and the practice of diagnosing and treating exposures to toxins and toxicants. The relationship between dose and its effects on the exposed organism is of high significance in toxicology. Factors that influence chemical toxicity include the dosage, duration of exposure (whether it is acute or chronic), route of exposure, species, age, sex, and environment. Toxicologists are experts on poisons and poisoning. There is a movement for evidence-based toxicology as part of the larger movement towards evidence-based practices. Toxicology is currently contributing to the field of cancer research, since some toxins can be used as drugs for killing tumor cells. One prime example of this is ribosome-inactivating proteins, tested in the treatment of leukemia. The word ''toxicology'' () is a neoclas ...

Scopus
Scopus is Elsevier's abstract and citation database launched in 2004. Scopus covers nearly 36,377 titles (22,794 active titles and 13,583 inactive titles) from approximately 11,678 publishers, of which 34,346 are peer-reviewed journals in top-level subject fields: life sciences, social sciences, physical sciences and health sciences. It covers three types of sources: book series, journals, and trade journals. All journals covered in the Scopus database are reviewed for sufficiently high quality each year according to four types of numerical quality measure for each title; those are ''h''-Index, CiteScore, SJR ( SCImago Journal Rank) and SNIP ( Source Normalized Impact per Paper). Searches in Scopus also incorporate searches of patent databases. Overview Comparing ease of use and coverage of Scopus and the Web of Science (WOS), a 2006 study concluded that "Scopus is easy to navigate, even for the novice user. ...

Science Citation Index
The Science Citation Index Expanded – previously entitled Science Citation Index – is a citation index originally produced by the Institute for Scientific Information (ISI) and created by Eugene Garfield. It was officially launched in 1964 and is now owned by Clarivate (previously the Intellectual Property and Science business of Thomson Reuters). The indexing database covers more than 9,200 notable and significant journals, across 178 disciplines, from 1900 to the present. These are alternatively described as the world's leading journals of science and technology, because of a rigorous selection process. Accessibility The index is available online within Web of Science, as part of its Core Collection (there are also CD and printed editions, covering a smaller number of journals). The database allows researchers to search through over 53 million records from thousands of academic journals that were published by publishers from around the world. Chemistry Citation Index Cla ...

EMBiology
EMBiology is a bibliographic database established in June 2005, and produced by Elsevier. ''EMBiology'' focuses on indexing the literature in the life sciences in general. Coverage includes science in the laboratory (fundamental research) and science in the field (applied research). It is designed to be smaller than EMBASE, with abstracting and indexing for 1,800 journals not covered by the larger database. However, there is some overlap. Hence, ''EMBiology'' is specifically designed for academic institutions that range from small to mid-size and all biotechnology and pharmaceutical companies. Global in scope, and with back file coverage to 1980, this database contains over four million bibliographic records, with an additional 250,000 records added annually. ''EMBiology''has cover to cover indexing of 2,800 active titles; these are peer reviewed journals, trade publications, and journals that are only in electronic format.

Current Contents
''Current Contents'' is a rapid alerting service database from Clarivate Analytics, formerly the Institute for Scientific Information and Thomson Reuters. It is published online and in several different printed subject sections. History ''Current Contents'' was first published in paper format, in a single edition devoted only to biology and medicine. Other subject editions were added later. Initially, it consisted simply of a reproduction of the title pages from several hundred major peer-reviewed scientific journals, and was published weekly, with the issues containing title pages from journal issues only a few weeks previously, a shorter time lag than any service then available. There was an author index and a crude keyword subject index only. Author addresses were provided so readers could send reprint requests for copies of the actual articles. Status Still published in print, it is available as one of the databases included in Clarivate Analytics' ISI Web of Knowledge ...
