Ferroelectric Nematic Liquid Crystals Showing High Birefringence

Advanced Science
High birefringence nematic liquid crystals are particularly demanded for adaptive optics applications in the infrared spectrum because it enable a thinner cell gap for achieving fast response time and improved diffraction efficiency.

Nonadditivity of critical Casimir forces

Nature Communications, 2016
The critical Casimir force, rising from fluctuating field confined between surfaces, is predicted to be nonadditive, but there is no experimental verification to date.

Cooperation in a fluid swarm of fuel-free micro-swimmers

Nature Communications, 2022
The authors introduce a light powered artificial micro-swimmers performing biological-like dynamics relevant for swarm robotics. The experimental dense swarms are shown to form artificial active clusters with internal fluid-like and turbulent dynamics ...

Diabetes‐induced vascular calcification is associated with low pyrophosphate and its oral supplementation prevents calcification in diabetic mice

FEBS Open Bio, EarlyView.
Induction of diabetes in three different mouse strains uniformly resulted in an increase in TNAP activity and a reduction in pyrophosphate (PPi) in the circulation. Inhibition of TNAP restored plasma PPi. Diabetes‐induced calcification in the media layer of the aorta was detected only in the Abcc6−/− strain, which is predisposed to ectopic ...

Development of low viscosity gel material suitable for modeling with 3D gel printer and evaluation of mechanical properties

Nihon Kikai Gakkai ronbunshu, 2018
Our group has developed a 3D gel printer called "SWIM - ER" (Soft and Wet Industrial Material - Easy Realizer). Here we are aiming to improve the gel material used in the SWIM-ER system for problems related to free forming and mechanical ...

Impact of a senior research thesis on students' perceptions of scientific inquiry in distinct student populations

FEBS Open Bio, EarlyView.
This study addressed how a senior research thesis is perceived by undergraduate students. It assessed students' perception of research skills, epistemological beliefs, and career goals in Biochemistry (science) and BDC (science‐business) students. Completing a thesis improved confidence in research skills, resilience, scientific identity, closed gender‐

Real‐World Performance of CSF Kappa Free Light Chains in the 2024 McDonald Criteria

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Kappa free light chains (KFLCs) in the cerebrospinal fluid (CSF) have a similar performance to CSF‐restricted oligoclonal bands (OCB) for multiple sclerosis (MS) diagnosis. To help with implementation, we set out to resolve several remaining uncertainties: (1) performance in a real‐world cohort and the 2024 McDonald criteria; (2 ...

What is fluidity? Designing an experimental system to probe stress and velocity fluctuations in flowing suspensions

EPJ Web of Conferences, 2017
We develop a method to investigate the microscopic origin of granular fluidity. We design a Couette cell in which we can probe the flow of soft hydrogel suspensions.
