A method for evaluating a catalyst layer formation transfer film is a method for evaluating a catalyst layer formation transfer film stacked on a base and transferred to form a catalyst layer of a fuel cell, which includes measuring a horizontal force by a SAICAS method while moving a cutting blade, and obtaining the maximum value of the horizontal force until the catalyst layer formation transfer film is broken after the cutting blade has been inserted into the catalyst layer formation transfer film and evaluating handleability upon transfer of the catalyst layer formation transfer film based on the maximum value of the horizontal force.

A resin composition quality controlling method includes a step of measuring a Raman spectrum of a resin composition composed of TiO.sub.2 particles dispersed in a base material mainly composed of a silicone rubber by irradiating the resin composition with laser, and a step of determining a concentration of the TiO.sub.2 particles in the resin composition based on an intensity of a fluorescence spectrum in the Raman spectrum.

A skin pore mimic, and more specifically, the skin pore mimic, according to one aspect of the present disclosure, includes a PDMS layer that includes polydimethylsiloxane and has a contact angle with water ranging from 90 to 110, in which the PDMS layer includes a plurality of holes that penetrate through an upper surface of the PDMS layer and a lower surface of the PDMS layer, thereby exhibiting characteristics similar to real skin in terms of hydrophilicity, elasticity, and the like, and enabling the simulation of sebum being secreted through pores. The skin pore mimic, according to one aspect of the disclosure, allows for an objective evaluation of the sustainability of a test material with respect to sebum.

Provided herein are porous, thin substrates (e.g., holey grids) comprising lipid bilayers formed across and/or within holes in the substrates, methods of forming bilayers within the holes of porous, thin substrates (e.g., holey grids), and methods of conducting structural analysis (e.g., by cryoEM) of membrane proteins, membrane-embedded particles, or membrane-attached particles within the lipid bilayers.

An object of the present invention is to provide a novel method for diagnosing film degradation which can identify the degraded state of a film based on a resin more efficiently and reliably than ever. In order to attain this object, a method for diagnosing the degradation of a film based on a resin is adopted, the method comprising using the following analysis method A and/or analysis method B, which is a non-destructive analysis method: analysis method A: confirming the presence or absence of abnormality in the film by visual observation and olfactometry, and analysis method B: confirming the presence or absence of an acid anhydride and a sign of hydrolysis reaction as to the film by Fourier transform infrared spectroscopy analysis.

The present disclosure provides a sensor system including one or more sensors having a first container fluidly coupled to a second container, the second container being configured to receive a conductive media from the first container. A first movable element is slidingly engaged with the first container to cause the second container to receive the conductive media from the first container. A first electrode is positioned in the first cavity and electrically coupled to the conductive media. In some examples, a second electrode is electrically coupled to the first electrode and the conductive media. The sensor deposits the conductive media on a working electrode to form an electrochemical cell and obtain one or more material properties of the working electrode. In some examples, the sensor system includes an array of sensors which deposit the conducive media in multiple locations on a working electrode to generate a material property map.

Coating materials such as paints, and/or coatings used to protect and improve the aesthetics of a material surface, develop the problem of degradation under environmental exposure. The degradation causes the coating to fail unexpectedly in its required applications. To keep this in check, the service life and change in material properties of a paint/coating need to be predicted before its use. Present disclosure provides system and method that implement a combined model to estimate the service lifetime and predict the chemical and physical changes in a coating material under various weathering conditions. The combined model captures the chemical modifications and physical modifications and affected properties like surface roughness, thickness loss, fracture toughness, gloss loss respectively. Chemical changes and physical changes are estimated correlated to help in estimating the service lifetime and degradation of the coating material.

The present invention is directed to provide novel laminates for wiring boards. Novel laminates for wiring boards according to the present invention includes an insulating substrate layer and copper wiring, the laminate having a circuit linearity of 1.0 or more and 1.7 or less.
