TL;DR: In this paper, residual wash solvent is removed from polyphosphite, e.g., bisphosphites, by a process comprising the steps of: A. Mixing the polyphophosphite crystals and residual washing solvent with a secondary alcohol, i.e., isopropyl alcohol (IPA), and B. Drying the mixture to remove the residual water solvent and secondary alcohol to a content of less than 0.5 wt% based on the weight of the polyophosphites.
Abstract: Residual wash solvent, e.g., ethyl acetate, is removed from polyphosphite, e.g., bisphosphite, crystals by a process comprising the steps of: A. Mixing the polyphosphite crystals and residual wash solvent with a secondary alcohol, e.g., isopropyl alcohol (IPA), to form a mixture of polyphosphite crystals, residual wash solvent and secondary alcohol, and B. Drying the mixture to remove the residual wash solvent and secondary alcohol to a content of less than 0.5 wt% based on the weight of the polyphosphite crystals.

TL;DR: In this article, the optical band gap of CCoTS-ME films was found vary with film thickness and structural and microstructural properties of the films were affected by the type of solvents.
Abstract: Direct deposition of Cu2CoSnS4 (CCoTS) films from molecular inks synthesized with three different solvents such as methanol (ME), isopropyl alcohol (IPA) and a mixture of methanol and isopropyl alcohol (ME+IPA) have been reported. The films were first dried at 150 °C followed by heated at 200 °C in air for 30 minutes to obtain the pure phase. It has been found that the films with ME resulted in continuous surface with smooth morphology while IPA and ME+IPA coated films show grains with microporosity. The films were pure stannite and show photoconductivity. The optical band gap of CCoTS-ME films was found vary with film thickness. In general, structural and microstructural properties of the films were affected by the type of solvents.

TL;DR: In this article, a heat exchanger that is coated with hydrophilic, deodorizing and antibacterial coating is provided, which can oxidize odorous sources without sunlight of ultraviolet spectrum by metal ion substitution.
Abstract: PURPOSE: A heat exchanger that is coated with hydrophilic, deodorizing and antibacterial coating is provided, which can oxidize odorous sources without sunlight of ultraviolet spectrum by metal ion substitution. CONSTITUTION: The method for fabricating a coating of heat exchanger includes the steps of preparing a photoconductive ceramics composite comprising (i) TiO2 0.57 mol/L prepared by using titanium isopropoxide £Ti(OCH(CH3)2)4| and isopropyl alcohol £(CH3)2CHOH|, (ii) SiO2 0.44 mol/L prepared by using tetraethyl orthosilicate tetraethoxysilane (C8H20O4Si) isopropyl alcohol £(CH3)2CHOH|, (iii) ZnO 0.5 mol/L prepared by using Zn acetate £Zn(C2H3O2)2| and (iv) silver, wherein weight percent of each component is TiO2 50 %, SiO2 40 %, ZnO 9 % and silver 1 %; mixing the photoconductive ceramics composite with a hydrophilic coating solution; applying the mixture solution on heat exchanger; and drying the coat at less than 300 deg.C.

TL;DR: In this paper, a process for extracting nucleic acids from a sample, which comprises the following steps: mixing the sample with a carrier which is at least one of the substances dextran, acrylamide or carboxymethylcellulose in order to produce a liquid mixture; mixing the liquid mixture with a reagent C, where the reagent A contained from the substances guanidinium thiocyanate, guaninium hydrochloride, potassium thiocoyanate and sodium thiocyclic acid, and at least
Abstract: The invention provides a process for extracting nucleic acids from a sample, which comprises the following steps: - mixing the sample with a carrier which is at least one of the substances dextran, acrylamide or carboxymethylcellulose in order to produce a liquid mixture; - mixing the liquid mixture with a reagent C in order to precipitate the nucleic acids and the carrier, where the reagent C contains at least one reagent A selected from the substances guanidinium thiocyanate, guanidinium hydrochloride, potassium thiocyanate and sodium thiocyanate, and at least one reagent B selected from the substances n-propyl alcohol, isopropyl alcohol, n-butyl alcohol, sec-butyl alcohol, tert-butyl alcohol and tert-amyl alcohol; and - separating the precipitated nucleic acids and the precipitated carrier from the liquid phase. The process is easier to use than the procedures hitherto practised, it contains a smaller number of steps, is able to reduce the possibility of aerosol formation, can be carried out within a short time, requires no phenol or chloroform and, nevertheless, achieves a constant efficiency of extraction of nucleic acids. Also disclosed is a method for detecting a particular nucleic acid sequence.
