The periodic table of the elements This figure is a tabular arrangement of the spi'al (fig. 2) and represents a “chart of matter” with the longitudes or groups and latitudes or periods.

The periodic table of elements, or Mendeleev’s table, was created in 1869 by Russian chemist Dmitri Mendeleev. This table organizes all known chemical elements by their atomic number, or the ...

Astronomers from the University of Turku in Finland and elsewhere have performed a broadband spectral and timing study of an ...

In one of Stanford’s labs, a roll of Scotch tape spins under a motorized roller. To the untrained eye, it’s an ordinary strip ...

Announced on the RSC website on June 25, the Perkin Prize, instituted in 2020, is one of the most prestigious accolades in the field of modern chemistry. Named after Sir William Henry Perkin, the ...

Collections Periodic table In this collection we explore the history and significance of the periodic table. We cover its origins and evolution, from Dmitri Mendeleev’s groundbreaking arrangement to ...

It’s a staple in drug development and industrial chemistry. And, remarkably, it worked. The peeling tape created enough of a jolt to overcome the energy barrier of the reaction.

The hydrothermal reactions of both PuO22+ and PuO2 with phosphonates results in the formation of Pu(IV) phosphonates. Pu(CH3PO3)2, Pu[CH2(PO3)2](H2O), and UO2Pu(H2O)2[CH2(PO3)(PO3H)]2 have been ...

Water transport in periodic mesoporous organosilicas (PMOs) was studied using pulsed field gradient NMR. A series of isogeometric PMO materials with different chemical compositions of the pore walls ...
