A method is provided for treating a tobacco material, comprising treating the tobacco material with an ionic liquid. Also provided is a tobacco material which has been treated by such a method, or a derivative thereof, and a smoking article which comprises a tobacco material treated by such a method.
The present invention relates to an LED illuminating device, comprising a heat sink (1), a light engine (2), an LED driver (3) and a driver housing (4) for accommodating the LED driver (3), a separation wall (A) being formed in the heat sink (1), and the light engine (2) and the driver housing (4) accommodating the LED driver (3) being arranged on a first surface and a second surface of the separation wall (A) opposite to the first surface, wherein the LED illuminating device further comprises a connector (5) that presses the light engine (2) on the first surface of the separation wall (A) and is locked with the driver housing (4) on the second surface of the separation wall (A).
Abstract Genetic fusion of elastin-like polypeptide (ELP) to the C-terminus of interferon alpha (IFN) generates a well-defined IFN-ELP fusion protein with high yield and well-retained bioactivity. The fusion protein significantly enhances pharmacokinetics, tumor accumulation, and antitumor efficacy of interferon alpha in a murine cancer model.
Provided is a mobile terminal. The present invention provides a sensor inside either or both of a receiver opening and a microphone opening, rather than providing an additional opening on the front panel of a device for installing the sensors, such that light is transmitted to the sensor via the receiver opening and/or the microphone opening, and the sensor transmits a signal via the receiver opening and/or the microphone opening; the receiver opening and/or the microphone opening are openings currently available on the front panel of the device, without the need of providing additional openings on the front panel of the device, reducing the number of the openings on the front panel of the device to make a mobile device more integrated, and provide better user experience due to an uncluttered surface of the front panel of the device.
The present invention relates to an illuminating device (100) comprising: a heat sink (1), a lens (2) and an electronic device housing (3), wherein the heat sink (1) comprises a circumferential wall (111) that defines an accommodating cavity (11) having a first opening and a second opening that are opposite, the lens (2) and the electronic device housing (3) are mounted in the accommodating cavity (11) from the first opening and the second opening, respectively, characterized in that one of the lens (2) and the electronic device housing (3) is fixed to the circumferential wall (111) and is fixed together with the other one of the lens (2) and the electronic device housing (3).
This invention provides a method for removing certain constituents from tobacco which includes a step in which ground tobacco is contacted with a solvent and subjected to an intensive mechanical action to generate a tobacco extract and an insoluble tobacco portion. The tobacco extract and insoluble tobacco portion may be separated, further treated to remove selected constituents and recombined. The product may be processed into a reconstituted tobacco sheet.
A writing device, comprising a writing unit; the writing unit comprises a pen head (2) for providing a light source, a pen holder (1) connected with the pen head (2) and used for transmitting light, and a pen point (3) connected with the pen holder (1) and used for writing words; the pen holder (1) is internally provided with a plurality of optical fibers (103) arranged in parallel in the length direction of the pen holder and used for transmitting light; the plurality of optical fibers (103) extend from the end of the pen holder (1) to the end of the pen point (3); and the light source is an LED point light source (21).
Composite powder for use in an anode of a lithium ion battery, whereby the particles of the composite powder comprise silicon-based domains in a matrix, whereby the individual silicon-based domains are either free silicon-based domains that are not or not completely embedded in the matrix or are fully embedded silicon-based domains that are completely surrounded by the matrix, whereby the percentage of free silicon-based domains is lower than or equal to 4 weight% of the total amount of Si in metallic or oxidized state in the composite powder.
