The neutron instruments suite, installed at the spallation neutron source of the Materials and Life Science Experimental Facility (MLF) at the Japan Proton Accelerator Research Complex (J-PARC), is reviewed. MLF has 23 neutron beam ports and 21 instruments are in operation for user programs or are under commissioning. A unique and challenging instrumental suite in MLF has been realized via combination of a high-performance neutron source, optimized for neutron scattering, and unique instruments using cutting-edge technologies. All instruments are/will serve in world-leading investigations in a broad range of fields, from fundamental physics to industrial applications. In this review, overviews, characteristic features, and typical applications of the individual instruments are mentioned.

Times Cited Count：5 Percentile：24.4(Chemistry, Multidisciplinary)A simple fabrication strategy of DNA-transcribed silica materials has been developed. An ionic liquid incorporating an alkoxysilane group is capable of binding with DNA and acts as nuclei for subsequent sol-gel reaction with tetramethoxysilane. Unique silica materials with worm-like, rod-shaped, toroidal, or linearly fibrous structures are created from the same DNA template through the morphological transition of DNA induced by the ionic liquid.

An effective mass processing equipment using solvent extraction method, named "emulsion flow extractor," is the most promising apparatus for removal and recovery of uranium from liquid waste originated from decontamination of uranium-contaminated fluoride waste in the uranium conversion test facility and of used gas centrifuges in the uranium enrichment facility at Ningyo-toge environmental engineering center. Prior to application of the emulsion flow extractor for actual uranium-containing liquid waste, properties of some phosphorous extractants for extraction and separation of uranium and constituents from simulated liquid wastes were examined through batch tests. These preliminary tests revealed that D2EHPA would be a promising candidate for extractant used for treatment of the actual uranium-containing liquid wastes, and that the extractants with a surfactant like AOT would not be useful.

A compound having diglycol amic acid frame, DODGAA, has been synthesized as a new "green" extractant for lanthanides. The new extractant composed, hydrogen, oxygen, and nitrogen atoms is fully combustible to gases without solid waste and its solubility in water is found to be very low. These properties enable us to avoid the burden of industrial waste produced by the incineration of deteriorated extractant and the risk of aquatic environmental pollution. In the extraction ability for lanthanide ions and the ability for their mutual separation, DODGAA is much superior to carboxykic acid type extractants, such as Versatic10, that can also be completely combustible. The extraction and separation performance of DODGAA is comparable to that of organophosphorus extractants, such as PC-88A and DEHPA, that are widely used in current industry but less "green".
