Adubação com digestato bovino e ureia e seu efeito na volatilização de N-NH3 do Solo

CONTRIBUCIONES A LAS CIENCIAS SOCIALES
O cultivo do milho possui exigência de uma quantidade maior de nitrogênio para obter boa produtividade. Esse macronutriente é suprido por meio da adubação nitrogenada com a ureia, porém, a sua aplicação proporciona elevadas perdas de N, principalmente, por volatilização de amônia (N-NH3).

Ammonium Salts as Curing Agents to Obtain Ionic Epoxy Resins With a Thermoplastic‐to‐Thermoset Transition

Advanced Materials, EarlyView.
Ionic epoxy networks are prepared using ammonium salts as hardeners, leading to a two‐stage curing process with a thermoplastic‐like intermediate. This uncommon behavior enables extrusion and fabrication of thermoplastic prepregs that can be cured into thermoset composites.

Field‐Programmed Anisotropy in Magneto‐Piezoelectric Composites for Material‐Encoded Mechanoperception

Advanced Materials, EarlyView.
Field‐programmed anisotropy imparts material‐level intelligence to soft composites. Magnetic torque dynamics drive magneto‐piezoelectric nanowires from random dispersion into deterministic axial alignment. The resulting hierarchical percolation networks confine electromechanical coupling to specific axes and intrinsically decouple superposed force ...

Stabilized Bi(III) Sites Direct *NH2OH Pathway for Efficient Cyclohexanone Oxime Electrosynthesis

Advanced Materials, EarlyView.
The electron‐buffering effect stabilizes Bi3+ sites under electroreductive conditions, preserving a favorable interfacial water configuration that sustains the selective *NH2OH pathway and enables efficient cyclohexanone oxime electrosynthesis. ABSTRACT Coupling electrocatalytic nitrite reduction reaction (NO2−RR) with cyclohexanone conversion enables ...
