Curing behavior of melamine-urea-formaldehyde (MUF) resin adhesive

International Journal of Adhesion and Adhesives, 2015
Abstract In this work, MUF resin was tested by DMA method. It showed that G ′ curves and strain curves together could be used to predict the curing behavior of MUF resins. The study showed that sequential formulation was preferred for the preparation of MUF resins. Hardener could accelerate the curing of MUF resins.

Short-Term Fine-Grained Regional MUF Prediction for HF Communication Based on Time-Series Decomposition

IEEE Transactions on Antennas and Propagation, 2023
High-frequency (HF) communication plays a vital role in military and commercial fields because of its characteristics of transhorizon propagation. Accurate prediction of the maximum usable frequency (MUF) is critical to improve the efficiency of HF ...

MUF-16: A Robust Metal-Organic Framework for Pre- and Post-Combustion Carbon Dioxide Capture.

ACS Applied Materials and Interfaces, 2021
One of the most critical environmental issues of our age is the escalating release of CO2 into the atmosphere. Separation technologies with low energy footprints may be an effective way to capture CO2 and prevent its accumulation.

Estimation of MUF(3000)F2 using Earth-ionosphere geometry for Karachi and Multan, Pakistan

Advances in Space Research, 2021
We report the estimation of the Maximum Usable Frequency of F2-layer for 3000 km circuit ( MUF ( 3000 ) F 2 ) using Earth-ionosphere geometry. The study is based on the assumption that h ′ F 2 may replace hmF 2 to estimate M ( 3000 ) F 2 .

Mixed matrix membranes (MMMs) using an emerging metal-organic framework (MUF-15) for CO2 separation

, 2020
Inorganic fillers can largely determine the ultimate performance of mixed matrix membranes (MMMs). The identification of new inorganic fillers is therefore crucial for the continued development of MMMs.
