Room Temperature Synthesis and Photopatterning of Mesoporous Titanium Dioxide Thin Films
Advanced Materials Technologies, EarlyView.A nanofabrication strategy combining deep‐UV photolithography with block copolymer self‐assembly enables direct patterning and mineralization of mesoporous TiO2 thin films at room temperature. Photocatalytic titanium oxo‐clusters promote polymer degradation under UV irradiation, enabling multiscale control over porosity, film thickness, and lateral ...

Quantum twist-deformed D = 4 phase spaces with spin sector and Hopf algebroid structures
Physics Letters B, 2019 We consider the generalized (10+10)-dimensional D=4 quantum phase spaces containing translational and Lorentz spin sectors associated with the dual pair of twist-quantized Poincare Hopf algebra H and quantum Poincare Hopf group Gˆ.

Riemann–Finsler geometry and Lorentz-violating scalar fields
Physics Letters B, 2018 The correspondence between Riemann–Finsler geometries and effective field theories with spin-independent Lorentz violation is explored. We obtain the general quadratic action for effective scalar field theories in any spacetime dimension with Lorentz ...

Some open questions on anti-de Sitter geometry [PDF]
, 2012 We present a list of open questions on various aspects of AdS geometry, that is, the geometry of Lorentz spaces of constant curvature -1. When possible we point out relations with homogeneous spaces and discrete subgroups of Lie groups, to Teichm\"uller ...

Advanced Optical Materials, EarlyView.Optical and plasmonic properties of TiN and Ti(O)N thin films were tuned at the synthesis stage by modulating the oxygen pressure during room‐temperature pulsed laser deposition. Ti(O)N thin films exhibiting a highly metallic and peculiar double‐epsilon‐near‐zero (DENZ) behavior were produced.

Advanced Optical Materials, EarlyView.Thermal expansion and the thermo‐optic effect in solids are closely coupled, reflecting concurrent changes in mass density and polarizability. Using echo‐resolved THz spectroscopy, we simultaneously determine sub‐micrometer thermal expansion and complex refractive index changes of MgO and Al2O3 from 10–325 K. The analysis yields both the coefficient of

Liquid Metal Sensors for Soft Robots
Advanced Robotics Research, EarlyView.This review thoroughly reviews liquid metal sensors in soft robots. Their unique material properties like high conductivity and good biocompatibility are analyzed. Working principles are classified, and applications in environmental perception, motion detection, and human—robot interaction are introduced.

The Classical Integral Operators in Weighted Lorentz Spaces with Variable Exponent. [PDF]
In this paper the Lorentz spaces with variable exponent are introduced. These Banach function spaces are defined on the base of variable Lebesgue spaces. Boundedness of classical integral operators are proved in variable Lorentz spaces.
