Abstract: Stabilized air filters formed from mats of crosslinked protein-containing fibers are provided. The fibers are formed into a mat with pores that allow air to pass through while physically filtering particulate matter. The protein in the protein-containing fibers also serves to chemically filter polluted air passed through the filter. Specifically, chemical functional groups from the many amino acids that comprise the protein of the protein-containing nanowire react with certain chemical pollutants (e.g., carbon monoxide and formaldehyde) in order to capture or otherwise neutralize the pollutant. Accordingly, the single fiber mat performs two filtering functions. Methods for making the air filters from crosslinked protein-containing nanofibers are also provided.

Abstract: A pixel circuit is provided which includes a data writing module, a drive module, a control module and an electrochromic device. The data writing module provides a data signal to the control terminal of the drive module under the control of a first control signal.

The control module controls the conduction between the drive module and the electrochromic device on the basis of a second control signal, and the control module controls the conduction so that the conduction is realized later than the change in the power supply voltage signal. The pixel circuit effectively removes interference of the power supply voltage signal, avoids display fluctuations caused by the change in the power supply voltage signal, and further improves the display effect.

Requests directed to a physical domain under relatively high pressure are queued up and sent to the physical domain on an I/O path having a relatively higher workload.
