An ionic liquid nanoparticles for dermal targeted delivery and effective anti-wrinkle treatment

open access: yesJournal of Dermatologic Science and Cosmetic Technology
Background: Aging is a natural process that cannot be stopped but retarded. Hydroxypinacolone retinoate (HPR) is a potent anti-wrinkle agent, but with severe irritancy, low stability, and poor water solubility, making it hard to apply in cosmetics. Ionic

Smart Materials for Smart Dentistry

open access: yes
Abstract The need of the hour is to introduce dental materials that have biomimicking properties of natural tooth structure. Various biocompatible materials have been introduced and widely used in many areas of dentistry. The smart behaviour of materials occurs when it senses some stimulus from the surrounding environment and reacts to it in a useful,

Development of a Three‐Axis Planar Hall Magnetoresistance Sensor Using a Superparamagnetic Nanoparticle‐Based Flux Guide

open access: yesAdvanced Functional Materials, EarlyView.
A printed superparamagnetic nanoparticle‐based flux guide enables the realization of a hysteresis‐free three‐axis magnetic sensor. This innovative architecture efficiently redirects out‐of‐plane fields to planar sensing elements, facilitating simultaneous vector detection without complex reset protocols.
