Abstract: The present disclosure provides stimuli-responsive particles, methods of preparing stimuli-responsive particles, and methods of using the stimuli-response particles. Unlike conventional platforms, (e.g., polymers, liposomes, dendrimers) the particles of the present disclosure have precise size control of the particle diameter, high uniformity, high stability, high active agent uptake capacity, minimal premature active agent leakage, biocompatibility, and biodegradability. Additionally, the present disclosure provides magnetic resonance imaging (MRI) systems and methods of using the MRI systems in combination with the stimuli-responsive particles described herein.

Abstract: A dough mixer includes a main unit with a motor arranged therein and a dough mixing assembly mounted thereon. The dough mixing assembly includes a dough mixing bowl, a top cover, a transmission shaft connected to the motor and is arranged in the dough mixing bowl, a dough mixing unit connected to the transmission shaft and including an upper end, and a scraper unit detachably connected to the upper end of the dough mixing unit. The scraper unit includes a first bowl wall scraper including a first blade fitted to an inner wall of the dough mixing bowl, a second bowl wall scraper including a second blade fitted to the inner wall of the dough mixing bowl, wherein the second bowl wall scraper is arranged opposite to the first bowl wall scraper, and a central scraper including a third blade matched with an outer wall of the transmission shaft.

Abstract: The present invention relates to a method of sensing aerosol characteristic parameters using dual-wavelength light scattered signals and the application thereof, and belongs to the technical field of fire warning. The method procedures include measuring the scattered light power of two different wavelengths, calculating the surface area concentration and the volume concentration of aerosol, and obtaining the Sauter mean diameter of the aerosol the surface area concentration, the volume concentration and the aerosol Sauter mean diameter are compared with corresponding thresholds, and then corresponding fire alarm signals are emitted.
