The present invention provides a method for obtaining a specifically-shaped crystal (specifically, spherocrystal) of a compound with good reproducibility. This method for producing a specifically-shaped crystal (specifically spherocrystal) of a compound comprises: (1) a step for preparing a supersaturated solution of a compound having a degree of supersaturation equal to or higher than a critical degree of supersaturation; and (2) a step for precipitating a specifically-shaped crystal (specifically spherocrystal) of a compound from the supersaturated solution.

The present disclosure describes electrochromic devices comprising transparent conductive layer acting as an electrode, an active electrochromic film, an ion conductor, and an ion storage film at least one of which comprises at least one MXene material.

An object of the present invention is to provide a crystal of L-alanyl-L-glutamine having a low loose specific volume, and a method for producing the same. The present invention relates to a crystal of L-alanyl-L-glutamine in which the loose specific volume is 5.0 mL/g or less, and a method for producing the same.

Methods of preparing hollow charge transfer co-crystals with reproducible habits and morphology are disclosed. The disclosed methods utilize surfactant to guide the crystal growth in aqueous solutions. The size and shape of the co-crystal can be controlled by the surfactant used, the concentration of the surfactant, and electron donor and electron acceptor, incubation temperature, and mixing condition.

A balloon catheter that includes an elongated main body, a balloon connected to the elongated main body, and a base layer on the outer surface of the balloon. The base layer includes a water-soluble low-molecular weight compound. The balloon catheter also includes a plurality of elongate bodies extending radially away from the outer surface of the balloon. The elongate bodies are crystals of a water-insoluble drug. The elongate bodies each possesses an independent longitudinal axis. At least part of at least some of the elongate bodies are located in the interior of the base layer on the outer surface of the balloon.

A balloon catheter that includes an elongated main body extending in an axial direction and a balloon connected to the distal portion of the elongated main body. The balloon includes an interior and is inflatable and deflatable. The balloon catheter also includes a plurality of elongate bodies extending radially away from the outer surface of the balloon. The elongate bodies are crystals of a water-insoluble drug. The elongate bodies each possess an independent longitudinal axis. Each of the elongate bodies includes a base portion at the proximal end of the elongate body. A plurality of elongate body proximal portions extend radially inwardly from the base portion of each of the elongate bodies toward the interior of the balloon. The elongate body proximal portions are continuous extensions of the crystal of the water-insoluble drug.

Electromagnetic waves are uniformly distributed on the light-receiving surface side by taking advantage of their property of being easily concentrated in sharp parts, and the front area (S.sub.A) on the emission surface side is made larger than the back area (S.sub.B) on the light-receiving surface side (S.sub.A/S.sub.B>1), thereby forming a more moderate electric field region. A reduced gold fine particle group (average particle size: 20 nm) was self-assembled on a transparent polyester resin film and half-submerged and fixed. This base material was repeatedly immersed in an electroless gold plating solution so that gold particles were deposited on the gold fine particles. 10 microliters of a protein solution was added dropwise to this nanostructured substrate, and crystallized by a hanging drop vapor diffusion method.
