Biodegradable sensor monitors levels of pesticides via direct contact with surface of fruit and vegetables
Publicado em 02 de fevereiro de 2024
Researchers at the University of São Paulo (USP) and the Federal University of Viçosa (UFV) in Brazil have developed a sustainable sensor that can be placed directly on the surface of a vegetable or fruit to detect the presence of pesticides. Known for this reason as "plant-wearable," it is made of cellulose acetate, a material derived from wood pulp.

One common misconception is that deer hunting is solely to blame for declining deer populations. While hunting can certainly [...]ver notícia -
Study shows potential of Southern cattail for phytoremediation of areas contaminated by mine tailings
Publicado em 15 setembro 2022Typha domingensis, the Southern cattail, a reedy marsh plant that inhabits fresh to slightly brackish waters and is about 2.5 m tall, can scavenge up to 34 times more manganese from contaminated soil than other plants found in similar environments. In a recent study, it accumulated between 10 and 13 times more manganese than other naturally occurring wetland plants such as hibiscus, sedges and rushes, demonstrating its potential for use in sustainable rehabilitation of areas affected by iron [...]ver notícia -
Application of Potassium to Grass Used as Cover Crop Guarantees Higher-Quality Cotton
Publicado em 16 fevereiro 2021The use of cover crops between cotton harvests protects the soil, conserves water, and reduces the risk of erosion. Researchers at the University of Western São Paulo (UNOESTE) and São Paulo State University (UNESP) in Brazil found that application of potassium (K) to a grass cover crop grown before cotton in sandy soil lowered production cost and resulted in cotton with a higher market value.
