A method of ultrasonic atomization of a workpiece material (104), in which the workpiece material (104) is simultaneously subjected to ultrasonic vibrations by means of an ultrasonic vibrating element (101) and melted by means of a focused radiation source (140). The melting comprises performing, simultaneously or alternately, the steps of directing (210) a radiation beam (139) originating from the radiation source (140) toward a specific location in a processing area (300) of the workpiece material (104) and/or the ultrasonic element (101) and supplying energy (220) to the processing area by means of the focused radiation beam (139). The step of supplying energy (220) is synchronized with the step of directing (210) to obtain melting lines arranged in a predefined pattern on the processing area (300). The distribution of the energy density supplied to the processing area (300) is defined by the density of the melting lines in the pattern used, and/or changing the speed of the radiation beam movement, and/or changing the parameters of the laser source.

The present application relates to a method for preparing 5-hydroxymethylfurfural under the mild catalysis of aluminum ions. The method comprises the following steps: S1, dissolving a carbohydrate and an aluminum ion salt in a solvent; S2, reacting same for 24-48 hours in a reaction atmosphere under the condition of 80-120°C; and S3, conducting filtering to obtain a 5-hydroxymethylfurfural sample, wherein the mass ratio of the carbohydrate to the aluminum ion salt is 1:1, and the mass-volume ratio of the carbohydrate to the solvent is (0.01-1 g):1 mL. In the solution of the present application, the reaction conditions are simple and mild, the yield of the obtained 5-hydroxymethylfurfural sample can reach 99.8%, and the 5-hydroxymethylfurfural sample has the same HPLC signals and the same infrared spectrum signals as a commercially available 5-hydroxymethylfurfural standard sample; moreover, no obvious byproduct peaks are observed in a nuclear magnetic resonance spectrum of the 5-hydroxymethylfurfural sample, indicating an extremely high product purity. Due to the high selectivity and high yield of the reaction, the separation and purification of 5-hydroxymethylfurfural are simplified, which facilitates subsequent reactions thereof.

Systems and methods for measuring EM field-carrying fluid flow use a difference in magnitude or phase of the field as the fluid flows. The difference indicates with fluid speed, and this relationship can be established beforehand, experimentally, or from the magnetic Reynolds number. Systems take advantage of the EM field, such as that created by a stator coil in an EM pump by detecting that field advected in the pumped fluid downstream. Magnitude or phase difference of the field, as reportable by a voltage in a conductive receiver reflects the flow rate, and thus speed, of the fluid between the initial and detected points. A computer or logic can thus readily output fluid rate, such as from a pump, from any electrical signal generated by the advected field. Systems do not require power, field induction, lengthy straight conduits, co-planar generators and sensors, flow interruptions, or large attachment or surrounding structures.

An optical system is described. The optical system comprises an input pupil for input of illumination radiation, and first and second field splitting stages. The first field splitting stage is configured to divide input illumination radiation into a first selected number of illumination beams along a selected first axis. The second field splitting stage is configured for receiving the first selected number of illumination beams and dividing said first selected number of illumination beam into a second selected number of illumination beams along a selected second axis. The optical system thus provides a selected number of illumination beams exiting through said output pupil and providing illumination of a region of a selected spatial shape.
