Conversions of parts per million on soil test reports to pounds per acre

Greater Pulp Yields per Acre per Year

Parts-per-million level loading organocatalysed enantioselective silylation of alcohols.

The field of organocatalysis has blossomed over the past few decades, becoming an alternative to transition-metal catalysis or even replacing the realm of transition-metal catalysis. However, a truly powerful organocatalyst with a high turnover number (TON) and turnover frequency (TOF) while retaining high enantioselectivity is yet to be discovered. Similar to metal catalysis, extremely low cat...

Real-time sensing of soil nitrate concentration in the parts per million range while the soil is in motion.

Reactive nitrogen (Nr) is a term used to describe non-nitrogen gas (non-N2) forms of nitrogen (N) in the biosphere. It causes major pollution problems when it occurs in excess, and it has many sources, including fertilizers used in production agriculture. Currently there is no on-the-go soil nitrate sensor that could guide the application of the optimal amount of fertilizer, which often varies ...

Selective monitoring of parts per million levels of CO by covalently immobilized metal complexes on glass.

Optical detection of parts-per-million (ppm) levels of CO by a structurally well-defined monolayer consisting of bimetallic rhodium complexes on glass substrates has been demonstrated.
