Novel polarimetric method for determination of the Brewster angle of a dielectric

Results in Optics, 2020
A novel polarimetric method for accurate determination of the Brewster angle of a solid dielectric material is presented. Plane polarized light incident on the surface of a dielectric at any angle of incidence remains plane polarized after reflection ...

Designation of the Boundary Conditions for Estimating the Thrust Loss due to Thruster-Hull Interactions

한국해양공학회지, 2022
The azimuth thruster is mainly installed on a vessel that requires a dynamic positioning (DP) function for special purposes. When the azimuth thruster on a vessel operates for DP, the thrust loss is induced by the thruster-hull interaction.

High‐Performance n‐Type Organic Thermoelectrics Enabled by Control Over Microstructure, Orientation and Contact Plane in Naphthalenediimide‐Bithiazole‐Copolymer Films

Advanced Functional Materials, EarlyView.
Effective control over the crystalline contact plane and microstructure of a naphthalenediimide‐bithiazole copolymer enables high‐performance n‐type thermoelectrics. While rubbing alignment induces a detrimental edge‐on orientation, subsequent solvent vapor‐induced re‐orientation facilitates a favorable mixed face‐on/edge‐on morphology.

The incidence and azimuth angles of hailfall

Suid-Afrikaanse Tydskrif vir Natuurwetenskap en Tegnologie, 1983
Simple equipment and mathematical methods for determining the incidence and azimuth angles of hailstones and a representative value of the wind speed during hailfall are presented. These techniques are currently employed in research in agriculture.

On the definition and practical use of crystal-based azimuthal angles

Journal of Applied Crystallography, 1989
A diffractometer-independent definition of the azimuthal angle ψ of a Bragg reflection is proposed. After completion of intensity measurement, instrument-dependent and partly redundant quantities such as orientation matrix and setting angles may be replaced by ψ, values without loss of information.

Biomineral‐Inspired Organic/Inorganic Colloidal Liquid‐Crystalline Hybrids for Photoresponsive Adhesion

Advanced Functional Materials, EarlyView.
A new class of photoresponsive liquid‐crystalline (LC) adhesives based on biomineral‐inspired organic/inorganic colloidal hybrids is reported. These colloidal LC materials are formed by hybridization of a hydroxyapatite nanorod with azobenzene‐based forklike molecules.

Meniscus‐Guided Soft‐Lithographic Assembly of Grid‐Type Molecular Martensite Films for Single‐Crystal‐Like Actuation

Advanced Functional Materials, EarlyView.
A meniscus‐guided microtransfer molding strategy enables scalable fabrication of grid‐type molecular martensite films with b‐axis‐correlated preferential texture. Sequential growth across microchannel intersections creates structurally continuous grids and robust thermoelastic actuation (∼11% strain, > 50 cycles, maximum force density: 7.1 × 109 N m−3).
