the research in new organic π-conjugated molecules with specific properties has become one of the most interesting topics in fields of materials chemistry. these materials are promising for optoelectronic device technology such as solar cells. on the other hand, the use of low band gap materials is a viable method for better harvesting of the solar spectrum and increasing its efficiency. the co...
having conducted the experiment and analysed the data, the researcher computed the groups mean scores and variances for the test relating to the research question. as the final atep, a t-test was conodonted for the hypothesis. as noted earlier, the significance level was determined at .05 and .01 respectively. the observed t-value was higher than the critical t-value at. 5 and .01 levels. conse...
OBJECTIVE "Classic" articles remain an important resource in teaching psychiatry. But, such materials are often buried in a faculty member's filing cabinet, effectively lost in today's world of instant access. We attempt to recover these materials through a marriage of traditional reading lists and contemporary technology. METHOD The authors created a sharable electronic filing cabinet to sto...
We present an organic materials database (OMDB) hosting thousands of Kohn-Sham electronic band structures, which is freely accessible online at http://omdb.diracmaterials.org. The OMDB focus lies on electronic structure, density of states and other properties for purely organic and organometallic compounds that are known to date. The electronic band structures are calculated using density funct...
This paper analyzed the current development of electronic teaching materials, and probed into the restricting elements of the development: digital copyright protection, readability and multi-format support. Also, it reviewed the current readers' digital rights protection technology, and introduced the basic principles and properties of e-paper,and synthesized the advantages of the LCD screen an...
