Crystalline networks based on dative boron–nitrogen bonds were obtained by combining polytopic N-donor ligands with polyboronic esters. The utilization of a tetrahedral boronate ester gave rise to a ...

Treating the polymers with a protic acid converts the nitrogen-linked phthalein structure into a conjugated form through the generation of ions in the backbone, which is supported by ...

Researchers have created a palladium-on-carbon catalyst for drug, pesticide, and plastic production that is very sparing in ...

Gaseous plasma generated by a half-wave rectified power supply are characterized and applied to the etching of photoresist and polymide in oxygen, dry air, or air. Activation energies of 8.6 kcal/mole ...

The problem with such a molecule, Schreiner says, is that it would be made from alternating single and double bonds between the nitrogen atoms, which would readily convert into triple-bonded N 2 ...

Conjugated polymers are organic macromolecules that are characterized by a backbone chain of alternating double- and single-bonds. Their overlapping p-orbitals create a system of delocalised π ...

Nitrogen fertilizers for corn. The most common ways to apply nitrogen fertilizers are to: Inject gas — anhydrous ammonia (NH3): Anhydrous ammonia is injected directly into the soil.It is often ...

Nitrogen dynamics after corn vs soybean crops Corn . On average, a bushel of corn will contain about 0.6 lbs of nitrogen. So the grain in a 200-bushel harvest will remove 120 lbs of nitrogen from ...

Polymer chemistry is the study of the synthesis, characterization and properties of polymer molecules or macromolecules, which are large molecules composed of repeating chemical subunits known as ...

Explore how PET and recycled PET fibers respond to thermal stress, with insights into implications for material performance.

The device successfully retained stored data for more than 10,000 seconds and distinguished between On and Off states over ...

We highly recommend the Polymer Clay Earring Making Kit for anyone interested in creating unique and beautiful earrings. Pros. The kit includes 33 different shapes of polymer clay cutters, 30 ...
