Abstract: Antibacterial coatings and methods of making the antibacterial coatings are described herein. A first branched polyethylenimine (BPEI) layer is formed and a first glyoxal layer is formed on a surface of the BPEI layer. The first BPEI layer and the first glyoxal layer are cured to form a crosslinked BPEI coating. The first BPEI layer can be modified with superhydrophobic moieties, superhydrophilic moieties, or negatively charged moieties to increase the antifouling characteristics of the coating. The first BPEI layer can be modified with contact-killing bactericidal moieties to increase the bactericidal characteristics of the coating.

Abstract: A method for avoiding transmission of side information by a Partial Transmit Sequence, comprising the following steps: Step 1: determining an indication sequence of a data sub-carrier and a pilot sub-carrier; Step 2: grouping the frequency domain data blocks including data and pilots to reduce the peak-to-average power ratio (PAPR) of the OFDM signal by phase rotation according to the PTS method. Step 3: processing the pilot of the received signal through channel estimation based on fast Fourier transform interpolation to obtain a frequency domain channel response, and extracting a phase rotation sequence. Step 4: equalizing the received data through the obtained frequency domain channel response. Step 5: performing inverse rotation of phase on the equalized data through the phase rotation information extracted in Step 3 to obtain transmitted data symbols.

Abstract: Embodiments are directed to a method of making an antifouling and bactericidal coating with tailorable surface topology. The method includes depositing a layer of branched polyethyleneimine (BPEI) and diamino-functionalized poly(propylene oxide) (PPO) in a mixture of water and organic solvent on a substrate to form a layer of BPEI/PPO. The method includes depositing a layer of glyoxal in a water-containing solution on the layer of BPEI/PPO. The method further includes curing the layer of BPEI/PPO and layer of glyoxal to form a homogenous, glyoxal crosslinked BPEI/PPO coating, where the curing induces local precipitation and alteration of the glyoxal crosslinked BPEI/PPO coating to provide a textured surface.

Abstract: According to one or more embodiments, a method of making an antifouling coating includes forming a polythioaminal polymer by reacting a fluorinated primary amine with an aldehyde to form an intermediate imine, and then reacting the intermediate imine with a dithiol. The method further includes depositing the polythioaminal on a substrate, and increasing a temperature of the polythioaminal deposited on the substrate to crosslink the polythioaminal and increase a contact angle of the substrate with crosslinked polythioaminal.

Abstract: Disclosed is an improved inner corner connector adapted to be secured at the intersections of container panels, such as walls, floors, and roofs. The inner corner connector includes a substantially horizontal base section with at least to substantially rigid flanges extending downward from the base section. The flanges are substantially parallel to each other and are spaced such that the resilient inner plate of a first panel snuggly fits between the two flanges. Extending upwards from the horizontal base are at least two flexible flaps that are configured to press against the inner plate of a second panel to create a thermal and moisture barrier at the intersection of the two panels. More than two flaps may be utilized to improve the quality of the thermal barrier, and the upper portions of the flaps may be joined together such that two flaps define an enclosed area.
