    Abstract: Provided is a titanic acid-based solid electrolyte material free from risk of production of hydrogen sulfide, free of rare earth, and having good electrochemical stability and lithium-ion conductivity. A titanic acid-based solid electrolyte material 1 is made of a titanate having a structure in which a plurality of host layers 2 are laid one on top of another, the host layer 2 being formed so that octahedra each formed of a titanium atom coordinated with six oxygen atoms are two-dimensionally chained while sharing ridges, and lithium ions 3 and divalent or higher-valent cations (α) 4 are intercalated in interlayers between the host layers 2, titanium sites in the host layers 2 being partially substituted by monovalent to trivalent cations (β).

    Abstract: Provided is a content processing method for determining a degree of priority of presentation of each of a plurality of contents, comprising: identifying the plurality of contents; receiving a first set including contents given positive evaluations from an operator and a second set including contents given negative evaluations from the operator from among the plurality of contents; extracting a first word set included in the first set and a second word set included in the second set; identifying a plurality of keywords including a plurality of positive keywords related to the first set and a plurality of negative keywords related to the second set according to a first evaluation criterion, the plurality of positive keywords being identified based on the first word set, the plurality of negative keywords being identified based on the second word set; giving weights to the plurality of keywords according to a second evaluation criterion so as to give a weight of zero or more to each of the plurality of positive keywords and give a weight of zero or less to each of the plurality of negative keywords; deriving a total for each of the plurality of contents by summing, over the plurality of keywords, a product of a frequency of appearance of each of the plurality of keywords and the given weight for the each of the plurality of keywords to obtain the total for each of the plurality of contents; and determining the degree of priority of presentation of each of the plurality of contents based on the total for the each of the plurality of contents.

    Abstract: Provided is a method for producing an organic tellurium compound that enables the production of an organic tellurium compound in high yield using metallic tellurium as a source material and produces less amount of side products. A method for producing an organic tellurium compound includes the steps of: (A) reacting metallic tellurium with a compound represented by a general formula (1) below; and (B) reacting a compound obtained by the step (A) with an organic halogen compound, the metallic tellurium having a copper content of less than 100 ppm, M(R1)m   Formula (1) where R1 represents an alkyl group having 1 to 8 carbon atoms, an aryl group or an aromatic heterocyclic group, M represents an alkali metal or an alkaline earth metal, m represents 1 when M is an alkali metal, and m represents 2 when M is an alkaline earth metal.

    Abstract: To provide an electrolytic solution that suppresses increase in the OH− ion concentration even in the case of electrochemical changes and thereby reduces deterioration or corrosion of resin, rubber, or metal to improve the reliability of an electrochemical device, an electrolyte used in the electrolytic solution, and an electrochemical device comprising the electrolytic solution. The electrolyte, for example, comprises a compound having a cation unit represented by the following formula and an electrolyte (a quaternary ammonium salt or the like). (In the formula, R1, R2, R3, and R4 are the same or different and each represent an alkyl group or an alkoxyalkyl group; R1 and R2 may together form a ring such as a pyrrolidine ring and a piperidine ring; and R3 and R4 may together form a ring such as a pyrrolidine ring and a piperidine ring.)
