in Chemistry, where it is implicitly assumed that the elements of the Periodic Table exist with their "natural" abundances without their origin and evolution being ever discussed, the case of the origin of protons and neutrons that constitute the matter that we ...
The depicted stainless steel autoclave is the heart of the presented methodology. It allows the performance of the method's key steps, which are the transition-metal-catalyzed in-situ generation of aldehydes and their subsequent organocatalytic activation. The resulting dipyrromethanes are directly ...
Although 1-D chains in 1–3 are all built of GaSe4 tetrahedra sharing opposite edges, these chains were classified as three types according to the period of the repeating unit. The crystal structure of type I (2) consists of 1-D common straight chains with [Ga2Se4]2− periodic units...

the stochastic process of natural selection may have favored individuals that required multiple bacterial cues before initiating rosette development, thus avoiding making the switch to rosette development under unfavorable environmental conditions. This integrated response may be especially important in aquatic ...
ofzirconium, the element directly above it in Group 4 of theperiodic table. The two elements are among the most difficult to separate—zirconium is almost always an impurity in hafnium and affects its physical properties. Finely powdered hafnium can spontaneously ignite in air; because of this ...

That is to say, when the diameter of a nanowire is smaller, its surface-to-volume ratio would be higher, which lead to the electrical properties of the nanowires significantly more sensitive to the specific gas molecules9. Moreover, quantum confinement effects in ZnO nanowires are only expected...
Eight is the number for oxygen in the Periodic Table, and element number 8 carries the core energy (electron) for the miracle of life and hydrogen (element number 1) donates the electron yielding the math of ‘9’. NASA have discovered that space is full of water, with ice crystals deep...
