The literature dealing with the electrochemical corrosion of copper and possibility of its prevention using inhibitors is examined. Inorganic compounds are investigated as well, but organic compounds and their derivatives in much greater numbers. Researches are directed to influence of compounds structure, concentration, method of application as well as media that inhibitor is used in on inhibi...

The thermo-optic coefficient (dn/dT) of inorganic–organic hybrid material films prepared by the sol-gel process of organoalkylsilanes is measured using a prism coupler equipped with a hot stage. The effect of the organic modifier on the variation of dn/dT in inorganic–organic hybrid material films has been investigated. The value of dn/dT becomes more negative with increasing molecular weight o...

We compared the mechanical properties of 'ordinary' bovine bone, the highly mineralized bone of the rostrum of the whale Mesoplodon densirostris, and mother of pearl (nacre) of the pearl oyster Pinctada margaritifera. The rostrum and the nacre are similar in having very little organic material. However, the rostral bone is much weaker and more brittle than nacre, which in these properties is cl...

Organic solar cells have advantages over the traditional inorganic solar cells. The flexibility and light-weight of an organic solar device lead to novel deployment unattainable by inorganic solar devices. There is a wide range of materials that can be used to fabricate an organic solar cell with many suitable conducting polymers and small molecules. The large number of appropriate materials me...

Copper-succinate-layered hydroxide (CSLH), a new nanohybrid material, was synthesized as an inorganic-organic nanohybrid, in which organic moiety was intercalated between the layers of a single cation layered material, copper hydroxide nitrate. Microporous scaffold carbon material was obtained by thermal decomposition of the nanohybrid at 500 °C under argon atmosphere followed by acid washing p...

Organic material is synthesized in the sunlit surface layer of the oceans and that is where most of it is decomposed back to carbon dioxide and other inorganic constituents. However, a small fraction escapes immediate degradation and makes its way into deeper waters, some as far as the bottom thousands of meters below the surface. This sinking organic material contributes to sequestering atmosp...

This research aims the development of universal indicators from organic waste materials. is a and (R&D) with modified ADDIE model. The indicator developed was implemented for students class XI MIPA at Senior High School in Bantul, Yogyakarta. data collection methods used are interviews, product validation sheets, observations, tests, questionnaires. results showed that can determine pH valu...
