Chemical etching methods and associated modules for performing the removal of metal from the edge bevel region of a semiconductor wafer are described. The methods and systems provide the thin layer of pre-rinsing liquid before applying etchant at the edge bevel region of the wafer. The etchant is less diluted and diffuses faster through a thinned layer of rinsing liquid. An edge bevel removal embodiment involving that is particularly effective at reducing process time, narrowing the metal taper and allowing for subsequent chemical mechanical polishing, is disclosed.

Sulfonated graft copolymer obtained by radical graft copolymerization of one or more synthetic monomers in the presence of hydroxyl-containing naturally derived materials. The graft copolymer includes 0.1 to 100 wt %, based on weight of the total synthetic monomers, of at least one monoethylenically unsaturated monomer having a sulfonic acid group, monoethylenically unsaturated sulfuric acid ester or salt thereof, with the monomer and hydroxyl-containing naturally derived materials present in a weight ratio of 5:95 to 95:5.

The invention relates to the technical field of high-molecular materials and particularly relates to an LED material for filtering yellow light and a preparation method thereof. The LED material for filtering yellow light is prepared from the following raw materials in parts by mass: 60-100 parts of a base material, 1-13 parts of a yellow light filtration aid, 0.1-1.0 part of a light diffusing agent, 0.1-0.8 part of an antioxidant, 0.2-0.4 part of a dispersant DP310 and 2-26 parts of deionized water, wherein the yellow light filtration aid is one or more than one of neodymium fluoride, neodymium oxide, neodymium chloride and neodymium nitrate. The LED material for filtering yellow light, prepared by the method disclosed by the invention, is excellent in optical performances such as yellow light filtration property, light transmittance and haze and can be used for effectively filtering and eliminating yellow light generated by an LED lamp so as to relieve the fatigue of eyes and preventing the eyes from damages of yellow light. The preparation method of the LED material is simple in process, convenient to operate and control, stable in quality, high in yield, high in production efficiency and low in production cost.

A printing system for use in printing objects of any of a plurality of different object types includes a printer; and a printer control device with a user interface having a first option for associating printer-independent print-quality characteristics with a selected object type to be printed by said printer. A printer-independent print-quality characteristic is an instruction associated with an element, such as object type, in an electronic page which indicates printer-independent features that are preferentially emphasized when printing the element. Examples of printer-independent print quality characteristics include “make sharp edges”, “reduce mottle”, “distinguish neighboring colors”, “reduce moiré”, “distinguish tone and edges”, “maximum tone depth”, “perceptual colors” and “compress without loss of detail”. The printing system may also include a device for retrieving printer-independent print-quality characteristics associated with a document to be printed by said printer and for associating printer-dependent imaging actions with the printer-independent print-quality characteristics.

The invention discloses a method for preparing tobacco pulp from regenerated tobacco. The method includes the following steps that 1, the tobacco raw material is extracted and then subjected to solid-liquid separation, and an aqueous solvent is added into tobacco filter residues obtained after solid-liquid separation, wherein the aqueous solvent contains salt and alkali and a nonionic surfactant; 2, the tobacco filter residues are fed into a pulping machine for defibering; 3, a complex enzyme preparation is added into the filter residues obtained after defibering for enzymolysis; 4, after enzymolysis is completed, pulping continues till the needed pulping degree is obtained, and the tobacco pulp is obtained. In the method for preparing the tobacco pulp, the pulp forming characteristic of the tobacco is effectively improved by organically combining the physical action, the enzyme preparation and the chemical reagent according to the specificity of the tobacco raw material, so that the effects of improving the papermaking property of the tobacco pulp and increasing the physical indexes of the regenerated tobacco are achieved, and meanwhile the interior quality of the regenerated tobacco is improved.
