Antifeedant Effect of Some Medicinal Plant Extracts .

Background and Objective: At present, insecticides with raw materials of active compounds from plants have become a strategic alternative, because they are easily obtained and produced. In an attempt to find natural and cheaper methods for the control of rice weevil (Sitophilus oryzae L.), some useless waste of local medicinal plant extracts was evaluated.

The Self-Assembly Phenomenon of Poloxamers and Its Effect .

Commonly used solvent methods include vacuum drying using rotary evaporators [44], spray drying [45], or freeze-drying [46], among others. In rotary evaporators, solvents are removed under reduced pressure, limiting thermal decomposition of the components of the mixture as organic solvent evaporation occurs at low temperature.

Molecular gastronomy is a scientific discipline, and note .

For the past two decades, there has been much confusion about molecular gastronomy. This confusion has arisen because people ignore that the word gastronomy does not mean cuisine, it means knowledge about food. Similar to 'molecular biology', molecular gastronomy is a scientific discipline that looks for the mechanisms of phenomena occurring during dish preparation and consumption.
