Thermal Degradation Kinetics and Flame‐Retardant Synergy in Zinc Borate/Red Phosphorus‐Filled Thermoplastic Polyurethane Composites

Journal of Vinyl and Additive Technology, EarlyView.
The synergistic interaction between red phosphorus (RP) and zinc borate (ZnB) enhances the thermal stability and flame retardancy of TPU by forming a dense, stable protective char layer. Non‐isothermal kinetic analysis confirms a complex degradation mechanism governed by conversion‐dependent activation energy.

Assessment of the effect of commercial vegetal oils on Kraft paper ageing through mechanical characterization

IEEE transactions on dielectrics and electrical insulation, 2018
Vegetal oils are considered a suitable substitute for mineral oil that is widely used in power transformers as insulation and cooling medium. Due to the fact that more and more power transformers containing this alternative insulating fluid are being ...

Evaluation Methodology, Numerical Verification and Retrofilling Procedure for Power Transformers to Ensure K‐Class Flame Retardancy and Environmentally Friendly

High Voltage, EarlyView.
ABSTRACT With increasing demands for fire safety and environmental friendliness, retrofilling transformers with alternative insulating liquids has become a growing trend. However, retrofilling power transformers remains uncertain, as more residual mineral oil compromises K‐class flame retardancy, and its impact on environmental performance has yet to ...

Growth of lettuce cultivars in beds covered with differing materials

Agro@mbiente On-line, 2019
In commercial lettuce growing, the intensive cultivation of the soil results in an increase in weed populations, making it difficult to fully exploit the area and increasing production costs.

Spatially resolved photo ionization of ultracold atoms on an atom chip

, 2007
We report on photo ionization of ultracold magnetically trapped Rb atoms on an atom chip. The atoms are trapped at 5 $\mu $K in a strongly anisotropic trap.

PPLP and kraft paper under high voltage in liquid nitrogen

2017 International Symposium on Electrical Insulating Materials (ISEIM), 2017
Liquid nitrogen impregnated PPLP and Kraft lapped papers are compared in terms of space charge distribution measurements for high voltage insulation in high power HVDC superconducting cables. Measurements with the pressure-wave-propagation method have shown that PPLP and Kraft paper samples behave similarly up to 30 kV/mm.

Residual Life Assessment of Oil‐Immersed Insulating Paper by FTIR Feature Interpretability Evolution

High Voltage, EarlyView.
ABSTRACT The ageing of insulating paper escalates the peril of insulation failure in oil‐impregnated‐paper power equipment. Consequently, the real‐time monitoring and non‐destructive assessment of insulating paper condition assume paramount significance.
