Abstract: Provided are a silicotitanate molded body having high strength and reduced generation of fine powder, a production method thereof, an adsorbent comprising the silicotitanate molded body, and a decontamination method of radioactive cesium and/or radioactive strontium by using the adsorbent. The silicotitanate molded body comprises: crystalline silicotitanate particles that have a particle size distribution in which 90% or more, on volume basis, of the particles have a particle size within a range of 1 ?m or more and 10 ?m or less and that are represented by a general formula of A2Ti2O3(SiO4).nH2O wherein A represents one or two alkali metal elements selected from Na and K, and n represents a number of 0 to 2; and an oxide of one or more elements selected from the group consisting of aluminum, zirconium, iron, and cerium.

Abstract: An information processing system that accepts a subscription from a user who presented a regular service code issued from a store where a prescription order for a contact lens by a doctor is confirmed, and sells the contact lens by regular delivery, the information processing system including a storage in which user identification information identifying a user who made the subscription, a regular service code issued to the user, contact lens information of the prescribed contact lens, a regular delivery date of the contact lens, and a purchase history of the contact lens of the user are stored in association with each other; a cancellation processing unit that, in a case where a notification is acquired from the user to cancel the purchase of the contact lens for the regular delivery date, executes a process of canceling the delivery of the regular delivery date, a delivery instruction output unit that outputs a delivery instruction to deliver the contact lens when the notification to cancel is not received

Abstract: Small and extremely small molecules and ions or atoms may be detected with the novel device with exceptional sensitivity. The detection is implemented in a simple manner by the known acoustic resonator FBAR or by means of other technologies that measure the physical properties of the filled layer. The permeability of substances (e.g. active ingredients) through membranes such as cell membranes, lipid bilayers, and cell walls can be examined by combining a sensor with the reservoir and the membrane.

Abstract: Provided is an adsorbent for removal of iodide ions and iodate ions, which exhibits excellent adsorption performance of iodide ions and iodate ions. An adsorbent according to the present invention comprises cerium(IV) hydroxide and a poorly soluble silver compound. It is preferable that the content of cerium(IV) hydroxide is 50% by mass or more and 99% by mass or less, and the content of the poorly soluble silver compound is 1% by mass or more and 50% by mass or less. It is also preferable that the poorly soluble silver compound is at least one selected from silver zeolite, silver phosphate, silver chloride, and silver carbonate.

Abstract: A method for measuring transport properties of cell membranes or lipid bilayers by providing at least a substrate having a topside and a backside and plurality of nano- or micro-pores and a cell membrane covering the plurality of pores being accessible from both sides of the cell membrane for measurement, a material layer at least in the region of the pores to support the cell membrane at the pores but not hindering the transport through the cell membrane and the pores arranged on the substrate, either on the topside or on the backside, applying a fluid containing at least one molecule to the topside of the membrane in order to allow the molecule to move through the membrane, one of the pores and the material layer, and monitoring of the molecules having passed the material layer by using an optical detection method.
