Glass insulated carbon-fiber microelectrodes (CFMEs) are standard tools for the measurement of neurotransmitters. However, electrodes are fabricated individually and the glass can shatter, limiting application in higher order mammals. Here, we developed a novel microelectrode batch fabrication method using a 3D-printed mold and polyimide resin insulating agent. The 3D-printed mold is low cost, ...

White mold is an agricultural disease caused by the fungus Sclerotinia sclerotiorum, which affects important crops. There are different ways of controlling this organism, but none provides inhibition of its resistance structures (sclerotia). Nanotechnology offers promising applications in agricultural area. Here, silver nanoparticles were biogenically synthesized using the fungus Trichoderma ha...

M. Górny, R. Dańko, M. Holtzer. AGH University of Science and Technology, Faculty of Foundry Engineering, Kraków, Poland This article addresses the effect of mold filling and wall thickness on the flake graphite layer in ductile iron. The research was conducted for castings with different wall thickness (3-8 mm) and using molding sand with furan resin. A thermal analysis has been performed alon...

Successful implementation of a high-speed roll-to-roll nanoimprinting technique for continuous manufacturing of electronic devices has been hindered due to lack of simple substrate preparation steps, as well as lack of durable and long lasting molds that can faithfully replicate nanofeatures with high fidelity over hundreds of imprinting cycles. In this work, we demonstrate large-area high-spee...

This study evaluated the sensitivity of an experimental model to mold temperature using a two-chamber casting machine and its recommended investment (Exp. 1), and the effect of sprue diameter and length using a one-chamber casting machine and its recommended investment (Exp. 2). Experimental patterns were cast from commercially pure titanium and percentage casting success obtained. Mold tempera...

Due to the rapid cooling of the slag infiltrated into the mold-strand gap, it is expected that the rate of devitrification of the glass formed plays a key role in determining the proportion of crystalline phases influencing mold heat transfer. In this investigation, a novel procedure to calculate Time-Temperature-Transformation (TTT) curves of mold slags is presented. It is based on the integra...

Fungi are essential components of ecosystems and widely distributed in nature. Fungal spores may be easily dispersed into indoor environments, and if conditions are suitable, some fungal spores may germinate and grow indoors. Mold, a common term for certain filamentous fungi, is fast growing and capable of producing hundreds of thousands of spores in a short period. Mold spores germinate and ra...

A retrospective study was carried out on 79 patients with a history of mold exposure, fatigue, and chronic rhinosinusitis (CRS) to determine whether there is a causal relationship between fungal exposure and chronic sinusitis, fatigue, and anterior hypopituitarism, especially growth hormone deficiency (GHD). Of the patients, 94% had a history of CRS, endoscopically and/or computed tomography (C...

A method based on the sidewall transfer technique for fabricating two-dimensional (2D) nano-mold on a silicon substrate was developed. Instead of using expensive nanolithography, the authors fabricated 2D silicon nano-mold using standard ultraviolet lithography, conformal deposition of gold by radio frequency sputtering, argon sputter etching and deep reactive ion etching (DRIE). This technique...

Biological specimens play an important role in cultural exchange, science popularization, scientific research and economic window, but the preparation and preservation technology system of biological specimens is relatively unsafe and inefficient. Mold grows seriously on animal specimens, which is not only harmful to human beings’ health and environment, but also is one of the factors that rest...
