What is made by the adresse of an article, and what is the definition of a scientific article and where we can find it?
3- We assume that this is the abstract of a scientific paperABSTRACT:
The sun has produced energy for billions of years. Solar energy is the sun's rays (solar radiation) that reach the Earth. This energy can be converted into other forms of energy, such as heat and electricity.
Photovolataic (PV devices) or "solar cells" change sunlight directly into electricity. Individual PV cells are grouped into panels and arrays of panels that can be used in a wide range of applications from single small cells that charge calculator and watch batteries to systems that power single homes, to large power plants covering many acres.
A scientific article is an article written for and published in a scientific research journal. It can be written by a single individual or by a group of scientists from either an academic institution or a business corporation. The purpose of the article is to share the results of research with the scientific community at large. The information is then in the public domain. Articles published in reputable, scholarly journals are peer reviewed and approved, meaning that the article has been scrutinized and edited by members of the scientific community for accuracy and scientific merit before being published.
If by the word "adresse" you mean address, I'm not sure what you are referring to. I think you may mean abstract, since you give an example abstract in the question box. The abstract of an article is a single paragraph summation of the entire article that is published at the very top of the first page of the article. This lets the reader get an idea of the paper and decide if he/she wants to read the entire article for more details.
In terms of access to these scientific journals, most require some sort of paid access and are not available for free. If you are a student at the university level, your school will most likely have a paid access to a wide variety of scientific journals available for student research. You can contact your school library for details. The website below gives examples of popular chemistry journals through the American Chemical Society.
