Processes for separating and isolating proteins and fats from biomass matter utilizes a pH adjustment of a slurry. The biomass feedstock is derived from commingled animal and/or plant-based streams with highly variable concentrations of fat, proteins and impurities present in the biomass. A wide range of pH adjustment spanning highly acid to highly basic has been shown to be effective at separating the commingled streams into their constituent products. The processes do not rely on the proteins being solubilized into the solution, but rather solubilizing the fat portion, physically separating the constituents and precipitating the fat in a downstream process, resulting in two value streams: a highly digestible protein component and a fat component. The protein component has nutritional value as companion pet, animal and aquaculture feed ingredient and the fat component has value as standalone or blended solid or liquid biofuels, greases or specialty chemicals.

The gate insulating layer is used in the capacitor area to increase the capacitance. The storage capacitor adopts the transparent electrodes to solve the issues of low capacitance of the storage capacitor and the unstable components caused by the reflected light.

A display unit includes multiple pixels, a first electrode, a partition wall, a light emission layer, and a second electrode. The multiple pixels each have a light emission region and a non-light emission region along a first direction. The first electrode is provided in the light emission region in each of the multiple pixels. The partition wall is provided between each two of the pixels that are adjacent to each other in a second direction. The second direction intersects the first direction. The light emission layer covers the first electrode and is provided in the light emission region and the non-light emission region in a continuous manner. The second electrode faces the first electrode across the light emission layer.

The present disclosure is related to a display substrate. The display substrate having a display area comprises a first electrode layer on a base substrate; a second electrode layer on a side of the first electrode layer far away from the base substrate; a light emitting layer between the first electrode layer and the second electrode layer; a pixel definition layer defining a plurality of sub-pixel regions with each of the plurality of sub-pixel regions containing the light emitting layer and the first electrode layer; and a signal line coupled to the second electrode layer. The signal line is substantially within the display area and at a different layer from the second electrode layer.
