Abstract: An airfoil component for attaching to a cropped airfoil is provided. The cropped airfoil comprises a cropped airfoil attachment section and a cropped first side opposite a cropped second side, which each extend axially between a cropped first edge and a cropped second edge to define a cropped chord length. The airfoil component comprises a body having a component first side opposite a component second side. The body defines an attachment section for attaching the airfoil component to the cropped airfoil at the cropped airfoil attachment section. The attachment section extends axially between a component first edge and a component second edge to define a component chord length, and the attachment section is oversized with respect to the cropped airfoil attachment section such that the component chord length is longer than the cropped chord length. Systems and methods also are provided.

Abstract: Single-domain antibodies that bind the severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) spike protein are disclosed. The single-domain antibodies include binding domains that bind epitopes of the Spike ectodomain inside and outside the receptor binding domain. The single-domain antibodies can be used for multiple purposes including in the research, diagnosis, and prophylactic or therapeutic treatment of COVID-19.

Abstract: Disclosed herein are methods for performing assays, including general functional assays, on a biological cell. Also disclosed herein are methods of barcoding the 5? ends of RNA from a biological cell and methods of preparation of expression constructs from the barcoded RNA. The barcoded RNA can encode proteins of interest, such as B cell receptor (BCR) heavy and light chain sequences. The expression constructs can be generated individually or in a paired/multiplexed manner, allowing rapid re-expression of individual proteins or protein complexes.

Abstract: Carbon nanotube (CNT) fiber and sheets formed by a specialized gas assembly pyrolytic reactor method that permits gas phase integration of nano and micro particles (NMPs) are processed into yarn and fabric used in the manufacture of personal protective clothing and equipment that can be tailored via selection of NMPs for a wide variety of functionality depending on target application. The CNT-NMP hybrid fabrics may be designed to exhibit enhanced electrical and thermal conductivity, moisture wicking, air filtering, and environmental sensing properties.

Abstract: A flat tube for a heat exchanger is fabricated from a single sheet of metal material. The sheet of metal material has a first edge and a second edge, which are arranged adjacent to one another between a pair of broad walls of the tube. Flat sections extend from the edges and are disposed against one another. A pair of rounded walls arranged at an end of the tube connect the flat sections to the broad walls, and are joined by a weld bead within a space bounded by the outer surfaces of the rounded walls.

Abstract: A method for annealing multi-walled carbon nanotubes includes applying a high-frequency electromagnetic field to the carbon nanotubes and causing the carbon nanotubes to self-heat to a temperature and for a time effective to reduce defects and reduce a number of walls in some of the carbon nanotubes.
