(1) MIT: New insights on fusion power

Research carried out at MIT's Alcator C-Mod fusion reactor may have brought the promise of fusion as a future power source a bit closer to reality, though scientists caution that a practical fusion powerplant is still decades away.

(2)Disappearing superconductivity reappears -- in 2-D

Scientists studying a material that appeared to lose its ability to carry current with no resistance say new measurements reveal that the material is indeed a superconductor -- but only in two dimensions. Equally surprising, this new form of 2-D superconductivity emerges at a higher temperature than ordinary 3-D superconductivity in other compositions of the same material.

Compendium of Pesticide Common Names

Compendium of Pesticide Common Names

Chemistry Online Resources

"For purposes of trade, registration and legislation, and for use in popular and scientific publications, pesticides need names that are short, distinctive, non-proprietary and widely-accepted. Systematic chemical names are rarely short and are not convenient for general use, and so standards bodies assign common names to the active ingredients of pesticides. More than 1100 of these official pesticide names have been assigned by the International Organization for Standardization (ISO), in accordance with an established system of nomenclature.

This Compendium is believed to be the only place where all of the ISO-approved standard names of chemical pesticides are listed. It also includes approved names from national and international bodies for pesticides that do not have ISO names"[1].
