Resumen de: WO2025211144A1
Provided is a charge-transporting ink composition for an upper layer of a quantum dot layer, the composition being configured such that: when used to form an upper layer of a quantum dot (QD) layer (light emission layer), the changes in the flatness of the film formed by inkjet deposition can be suppressed, such changes occurring due to the post-deposition time delay; practical charge-transporting properties can be maintained; and photoluminescence (PL) quenching of the quantum dot (QD) layer in the element obtained is not triggered. The composition contains a charge-transporting material and a solvent, where the solvent is a specific solvent having a Balaban index of 3.3 or lower and a molar refractive index of 65 or lower, and also having a boiling point of 180°C or higher.

Resumen de: WO2025210507A1
The present invention concerns the field of implantable neural interface devices and, in particular, it refers to a new process for fabricating polymeric neural interfaces based on a combination of molding and screen printing, and to the interfaces thus obtained. The invention simplifies the process for fabricating the above-mentioned devices, both from an operational point of view and from a cost reduction perspective.
Resumen de: WO2025211351A1
The problem with conventionally known conductive materials has been low dispersibility in an adhesive, a resin, a mold release agent, or the like. In order to solve the above problem, the present invention uses a conductive polymer composition characterized by comprising: (A) a polythiophene containing two or more structural units which are at least one kind selected from the group consisting of structural units represented by general formula (1) and structural units represented by general formula (2); and (B) a polyether-based compound represented by general formula (16).
