Driving Micro‐Objects Using Optical Force due to Fluorescence Emission From Molecules
Emission of fluorescence from a micro‐object in a specific direction is expected to generate an optical force driving the object in the opposite direction of the emission, like a rocket. To demonstrate this ‘photon‐driven micro‐rocket’, we prepared dye‐doped polymer micro‐object (PMO) one surface of which was covered with metallic film; the PMO ...

The Neodymium(III) macrocyclic complex [NdL(CF3SO3)3] serves as a non‐contact, bifunctional sensor for temperature and pressure, displaying field‐induced Single Molecule Magnet (SMM) behavior. At 3 GPa, triflate rotations halt, triggering a disorder‐order phase transition from centrosymmetric phase α to noncentrosymmetric high‐pressure phase β.

By combining static and time‐resolved optical, structural, and rheological techniques, we demonstrate that the blue‐shift upon solidification of ethyl cellulose‐acrylic acid mesophases corresponds to the reorientation of cholesteric domains. Modulating the mesophase chain mobility and photopolymerization reaction kinetics enables solid chiral nematic ...

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering
Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create

Hopf-type estimates for solutions to Hamilton-Jacobi equations with concave-convex initial data
We consider the Cauchy problem for the Hamilton-Jacobi equations with concave-convex initial data. A Hopf-type formula for global Lipschitz solutions and estimates for viscosity solutions of this problem are obtained using techniques of multifunctions ...

Curvature and dielectric is introduced to tune properties of surface phonon polaritons (SPhPs) in complementary nanostructures: nanowire (NW) and nanohole (NH). It is found that NH complements the frequency band range of SPhP of NW. Frequency‐band subinterval of the SPhP in NHs and NWs can be tuned by dielectric.

From Spider-Man to Hero — Archetypal Analysis in R
Archetypal analysis has the aim to represent observations in a multivariate data setas convex combinations of extremal points. This approach was introduced by Cutler andBreiman (1994); they dened the concrete problem, laid out the theoretical ...

Inflatable kirigami crawlers are fabricated from heat‐sealable textiles and achieve motion through cyclic pneumatic actuation. Strategically placed kirigami cuts guide asymmetric deformation, doubling contraction compared to traditional pouches and forming scale‐like surfaces.
