In this article, we study on the effect of different congregated granularities of microencapsulated n-octadecane on polyurethane foamed system, and the making of the polyurethane foams with high contents of microencapsulated n-octadecane. The results show that, when relative low granularities of microencapsulated phase change materials (MicroPCMs) are used as additives, the remnant water and fo...

This article reviews the state of the art in the field of porous amorphous metals by describing current processing techniques, mechanical properties, and potential applications. In addition to the reduction in density, the main benefit of introducing porosity in amorphous metals is the improvement in compressive ductility and energy absorption. This ductilizing effect is explained by: (1) shear...

During earlier studies on vacuum concentration of liquid egg white, the phenomena of foaming during the initial stages of the process were reported. In these studies, it was also shown that no concentration took place during the foaming period that varied from test to test. To minimize the total process time, this present study was undertaken to investigate what variables contributed to foaming...

Near-stoichiometric NiTi was foamed in the solid state at elevated temperatures through creep expansion of highpressure argon pores previously entrapped during powder consolidation. A sample with 17% porosity was found to be superelastic up to a compressive stress of 800 MPa.

Both theoretical and experimental results on evaluating hidden water in building materials are reported to compare features of optical and microwave heating. Experiments have been performed on a 2 cm-thick reference sample made of gypsum pasteboard which contained voids filled with foamed polyurethane. The obtained results are compared to illustrate that advantages of microwave moisture detecti...

Forced coalescence of liquid marbles is reported. Liquid marbles were connected by a glass rod hydrophilized with cold radiofrequency plasma. The process resulted in formation of Janus-marbles. “Sandwich” marbles enclosing solid foamed polystyrene particles and built from immiscible liquids are reported. A broad variety of organic and non-organic powders gives rise to Janus and “sandwich” marbles.

We investigated the effect of sugar cane level and foaming process on properties, drying kinetics, physicochemical properties dried pasta sauce. Experiments were conducted sauce based tomatoes, both non-foamed foamed, at selected concentrations (0, 15, 30% g sugar/g concentrated tomato) a constant temperature 60.C. The results indicated that density viscosity foamed lower than sauce, thereby in...

The design of porous metal structures is of high interest for novel lightweight industrial applications. Synchrotron tomography in combination with 3D image analysis is the suitable method to investigate these structures. In order to bring the foam production process from the laboratory to industrial scales a detailed knowledge of the control parameters’ influence on the resulting pore structur...
