On the basis of the scaffolds widely used in drug design, a series of novel spirooxindole derivatives containing hydantoin, thiohydantoin, urea, and thiourea moieties have been designed, synthesized, ...

Khargone: Farmers on Wednesday blocked Chittorgarh-Bhusawal highway in Bistan Naka area of Khargone demanding they be provided urea fertiliser followi.

We present a new class of catalysts based on the combination of N,N′-diaryl(thio)ureas and weak silicon Lewis acids (e.g., SiCl4). Such silicon−(thio)urea catalysts effectively catalyze the ...

The objective of this experiment was to quantify the effects of feeding polymer-coated slow-release urea on nutrient intake and total tract digestion, milk yield and composition, nutrient balances, ...

Explore how Middle East turmoil impacts Australia's urea and diesel supplies, calling for a review of the 'just in time' policy.

China is loosening its ban on urea exports, a move likely to ease international prices that have been buoyed by the recent tension in the Middle East.

Reactor on the edge of a droplet Signorell's team studied tiny water droplets such as those found in sea spray and fine mist. The researchers observed that urea can form spontaneously from carbon ...

Urea is considered a possible key molecule in the origin of life. ETH researchers have discovered a previously unknown way in which this building block can form spontaneously on aqueous surfaces ...
