Concurrent Quantitative Conductivity and Mechanical Properties Measurements of Organic Photovoltaic Materials using AFM

Organic photovoltaic (OPV) materials are inherently inhomogeneous at the nanometer scale. Nanoscale inhomogeneity of OPV materials affects performance of photovoltaic devices. In this paper, we describe a protocol for quantitative measurements of electrical and mechanical properties of OPV materials with sub-100 nm...

Layer-by-layer Collagen Deposition in Microfluidic Devices for Microtissue Stabilization

The creation of functional microtissues within microfluidic devices requires the stabilization of cell phenotypes by adapting traditional cell culture techniques to the limited spatial dimensions in microdevices. Modification of collagen allows the layer-by-layer deposition of ultrathin collagen assemblies that can stabilize primary cells, such as hepatocytes, as microfluidic tissue...

Output Efficiency: Achieving Output Efficiency01:26

Output Efficiency: Achieving Output Efficiency

Output efficiency happens when resources are used in a way that balances what people want with how goods are produced. This means the marginal rate of substitution (MRS) matches the marginal rate of transformation (MRT). When this balance is reached, the economy makes the most of its resources without waste.Take the example of bread and milk. If consumers are happy to trade 2 loaves of bread for 1 liter of milk, the MRS is 2. But if producers only need to give up 1 loaf of bread to produce 1...

Analyzing Dendritic Morphology in Columns and Layers

Here, we show how to analyze dendritic routing of Drosophila medulla neurons in columns and layers. The workflow includes a dual-view imaging technique to improve the image quality and computational tools for tracing, registering dendritic arbors to the reference column array and for analyzing the dendritic structures in 3D...
