The severe adhesion between silicon and glass has limited its application as mold material in precision glass molding. In this paper, a novel coating approach to create non-stick silicon mold for glass molding was introduced by using carbide-bonded graphene, a two dimensional material with a patterned atomic structure. A graphene coated silicon mold was fabricated using a coating process develo...

Indoor mold growth has recently become a concern in the legal world in regards to insurance litigation. Hazardous mold exposure to humans has been linked to many acute and chronic adverse health effects including death. As it grows, mold produces several types of primary and secondary metabolites, including microbial volatile organic compounds (MVOCs). Microbial volatile organic compound emissi...

New products must be more quickly and cheaply developed, manufactured and introduced to the market due to the pressure of global competition. This work demonstrates a technique for producing accurate wax patterns made from a high precision silicone rubber mold. Silicone rubber mold is cut into five components, which is the minimum number of components for assembling the silicone rubber mold. Th...

1. A powerful kinase which changes trypsinogen to trypsin was found to be present in the synthetic liquid culture medium of a mold of the genus Penicillium. 2. The concentration of kinase in the medium is increased gradually during the growth of the mold organism and continues to increase for some time even after the mold has ceased growing. 3. Mold kinase transforms trypsinogen to trypsin only...

A cooling channel with an optimized design provides not only high throughput gravity die casting, but also guarantees product quality. conformal (CC) whose structure follows the shapes or surfaces of mold cavity has attracted great attention in casting industry, because it allows rapid and uniform cooling. However, implementing remains highly challenging, complicated geometries CC are difficult...

Background: Butter is one of the oldest dairy products known in the world and plays an important role in human nutrition. The aim of this study was evaluating of the microbial quality of traditional   and industrial butter marketed in Zanjan. Methods: In this descriptive cross-sectional study, a total of 29 samples of butter were investigated in 2 groups which 24 samples were of trad...

The UV polymerization process dictates the materials that can be employed in the sheath-flow device downstream from the hydrodynamic focusing grooves. The primary requirement for UV polymerization is an integrated window through which the shaped core can be polymerized using a UV source. Possible options include the use of all PDMS parts, top and bottom, or a combination of PDMS and silicon/gla...

Continuous casting plants are highly complex plants whose performance requires reliable mold level control system. Several effects greatly influence the surface quality of the final product and if these are not suppressed sufficiently by the mold level control system, than the production speed, hence the productivity has to be lowered. This paper analyses the most important disturbance and thei...

We present a simple and effective mold cleaning method for nanoimprint lithography. Polydimethylsiloxane (PDMS) prepolymer is spin-coated onto a contaminated imprint mold, thermally cured in ambient environment, and then peeled off afterwards. Contaminants of 100s m to sub-50 nm sizes are effectively cleaned within one cycle. During the cleaning process, a very thin PDMS film (1~2 nm) is unifo...
