Abstract: A heterojunction cell and a method for preparing same. The heterojunction cell comprises: a semiconductor substrate layer; and an intrinsic semiconductor composite layer, wherein the intrinsic semiconductor composite layer is located on the surface of at least one side of the semiconductor substrate layer, and the intrinsic semiconductor composite layer comprises: a bottom intrinsic layer; and a wide-band-gap intrinsic layer, which is located on the surface of the side of the bottom intrinsic layer that is away from the semiconductor substrate layer, the band gap of the wide-band-gap intrinsic layer being greater than the band gap of the bottom intrinsic layer. The band gap of a wide-band-gap intrinsic layer is larger, and when sunlight irradiates a heterojunction cell, photons, the energy of which is less than that of the band gap of the wide-band-gap intrinsic layer, cannot be subjected to parasitic absorption.

Abstract: Disclosed are fibrin-specific nanogels. The fibrin-specific nanogels can comprise a fibrin binding moiety conjugated to a polymeric matrix (e.g., a crosslinked polyacrylamide matrix). By varying the morphology of fibrin-specific nanogels (e.g., by varying the crosslinker density and/or the three-dimensional structure of the fibrin-specific nanogels), fibrin-specific materials which mimic the biophysical characteristics of platelets can be formed. The resulting materials can be used in a variety of biomedical applications (e.g., for drug delivery, to promote wound healing, to treat thrombotic events, and to treat coagulative disorders).

Abstract: A locking mechanism for mounting hard drive to rack includes a shell and a lock component. The lock component comprises a handle, a pin, a lever, a torsion spring, and a compression spring. When the handle is located on the inner position, the lever latches the handle, the torsion spring is compressed, the compression spring pushes the pin out of the shell to insert into a slot of the rack to lock the hard drive to the rack. When pressing the lever to unlatch the handle, the torsion spring pushes the handle rotate to the outer position, meanwhile the handle retracts the pin into the shell to unlock the hard drive from the rack. An electronic device structure and a server using the locking mechanism is also disclosed.

Abstract: The present disclosure relates to the preparation method of glufosinate or derivatives thereof.

Abstract: Using lung tissues as a source, mammalian lung progenitor cells lung spheroids and lung spheroid cells (LSCs) were prepared. In one embodiment mammalian LSCs were prepared by (i) culturing mammalian lung tissue explant cells under adherent culture conditions to form a first lung cell outgrowth culture; (ii) culturing the first lung cell outgrowth culture under low-adherence conditions to form lung spheroids; and (iii) culturing the lung spheroids under adherent culture conditions so as to form LSCs. The low-adherence conditions may be a cell culture or suspension. The lung spheroids or LSCs may be formulated into pharmaceutical compositions. Uses such as treatment of lung diseases or diagnostics are also provided. Lung spheroids and LSCs represents a simple and highly reproducible method to generate therapeutic lung cells.

Abstract: A carrier tray to allow rapid installment of additional modules or devices, without screws, into a computer includes a frame, two sliders, an elastic member, and a handle. A bracket of the frame has a unit cavity. The two sliders can slide along a first direction and the elastic member is compressible between the two sliders. The handle allows pushing and pulling of the tray along a second direction and is attached to the two sliders, the two sliders can move towards each other (to a first position) or apart (to a second position). The two sliders return to the unity cavity by pulling the handle from the first position to the second position along the second direction. Continued pulling of the handle in the second direction removes the carrier tray from the computer.
