The objective of this study was to determine the physicochemical and sensory properties of Appenzeller cheese supplemented with different concentrations (0, 1, 2, 3, and 4%, w/w) of powdered microcapsules of tomato extracts (PMT) during ripening at 14℃ for 6 mon. The particle sizes of PMT ranged from 1 to 10 m diameter with an average particle size of approximately 2 m. Butyric acid (C4) concen...

One of the most important tasks remaining to be resolved in nanoimprint lithography is the elimination of the resist sticking to the mold during demolding. Previously, the main approach was to apply a thin layer of fluorinated alkyl silane mold-release agent on the surface on the mold; however, this involves complicated steps and high costs. The low surface free energy material polybenzoxazine ...

Mold Shape Deposition Manufacturing (Mold SDM) is a Solid Freeform Fabrication technique for producing complex shaped fugitive wax molds. A variety of castable polymer and ceramic materials have been used to make parts from these molds. This paper describes the Mold SDM method and an automated mold building machine based on a commercial CNC mill. Process steps, material selection and equipment ...

The air-gap nucleation time, the stress evolution and the solid shell growth pattern are examined for different mold topographies to illustrate the potential control of aluminum cast surface morphologies during the early stages of solidification using proper design of mold topographies. The interaction between heat transfer and deformation during the early stages of solidification is considered...

This work combines two industrially friendly processing methods in order to create wear resistant and solid-lubricating composite coatings potentially suitable for high load applications. Layered were fabricated over wrought stainless steel 444 (SS444) by compression molding a mixture of solid lubricant polymer, polytetrafluoroethylene (PTFE, 80 wt%), polyimide (PI, 20 onto iron aluminide (Fe3A...

In thermal characterization tests of bone cement according to the ASTM Standard Specification for Acrylic Bone Cement, time-temperature profiles of bone cement were observed to be sensitive to the thickness of the cement patty and the mold material. Due to the heat transfer from cement to the surrounding mold, such tests might underestimate the exothermic temperature of bone cement. Developing ...

Introduction and scope. “Mold spores are omnipresent, and a constantly elevated humidity in given building containing organic components will inevitably lead to [fungal] growth and subsequent damage to the materials” (Gravensen, 1999). In recent years indoor fungal growth and airborne particles have gained the reputation of a serious health threat. The extent to which this perception is justifi...

Steady-state finite-element models have been formulated to investigate the coupled fluid flow and thermal behavior of the top-surface flux layers in continuous casting of steel slabs. The 3-D FIDAPTM model includes the shear stresses imposed on the flux/steel interface by flow velocities calculated in the molten steel pool. It also includes different temperature-dependent powder properties for ...
