Elasticity‐Driven Periodic Polarization Patterns in a Chiral Ferroelectric Nematic Fluid
Advanced Materials, EarlyView.Chiral polar ferroelectric nematic fluids exhibit spontaneous formation of stripe, square, and hexagonal polarization textures under confinement. Controlled by thickness and anchoring, these patterns produce spatially modulated nonlinear optical responses.

Spin Transport Across Interfaces With the Non‐Collinear Antiferromagnet Mn3Sn
Advanced Materials, EarlyView.We study spin transport with Mn3Sn|Metal${\rm Mn}_3{\rm Sn}\vert{\rm Metal}$ heterostructures. For Mn3Sn|Pt${\rm Mn}_3{\rm Sn}\vert{\rm Pt}$ heterostructures, ultrafast spin current generation by optical pumping of Mn3Sn${\rm Mn}_3{\rm Sn}$ is explored, while for Mn3Sn|NiFe${\rm Mn}_3{\rm Sn}\vert{\rm NiFe}$ heterostructures, we probe the spin–charge ...

BEZPIECZEŃSTWO I PORZĄDEK PUBLICZNY NA PRZYKŁADZIE II RP
PRZEGLĄD POLICYJNY, 2017 Znajomość burzliwych dziejów państwa polskiego, w tym dziejów policji, jest konieczna dla rozumienia etosu służby. Policja Państwowa, mimo wielu niedoskonałości w swojej organizacji, w ogólnym zarysie daje wzorce nacechowane patriotyzmem, podkreślając rolę etosu w policyjnej służbie.

Sub‐nm2 Ferroelectric Domains via Charged 180° Walls in ZrO2
Advanced Materials, EarlyView.Ferroelectric ZrO2${\rm ZrO}_2$ thin films host closely spaced charged 180∘$^{\circ }$ domain walls that vertically compress polar domains beyond their lateral half‐unit‐cell limit. These head‐to‐head and tail‐to‐tail walls show distinct bulk‐like structures, natural oxygen‐mediated stabilization, and highly asymmetric mobility, highlighting new ...

Nonplanar Bouligand Architectures for Enhanced Mechanical Performance in Cementitious Composites
Advanced Materials, EarlyView.Inspired by the impact region of the Mantis shrimp dactyl club, nonplanar additive manufacturing translates sinusoidal Bouligand architectures into cementitious composites. Printing‐induced anisotropy and architected interfaces promote distributed damage and arrest crack propagation, enhancing strength and energy absorption.

Efficient in‐Plane Exciton Transport in a Discontinuous Layered Lead‐Bromide Perovskite
Advanced Materials, EarlyView.A new class of two‐dimensional lead‐bromide perovskite based on monovalent 4‐aminomethylbenzoic acid cations is presented, featuring a discontinuous inorganic layer. Despite the discontinuous lattice, transient photoluminescence microscopy demonstrates efficient though strongly anisotropic in‐plane exciton transport.

Advanced Materials, EarlyView.Alternating oxidative–reductive pulses synchronize CO2‐derived *CO and NH3‐derived *NHx intermediates over dual Cu and Co single‐atom sites, enabling urea and ethyl urea formation with a total C─N Faradaic efficiency of 42 ± 4%. In situ spectroscopy and theoretical calculations elucidate complementary Cu and Co functions, while oxidative controls ...

Chiral Phonon–Driven Ultrafast Spin Currents in a Non‐Magnetic Ferroelectric
Advanced Materials, EarlyView.Broadband terahertz emission spectroscopy shows signatures of ultrafast spin‐current generation in non‐magnetic ferroelectric β$\beta$’‐In2Se3${\rm In}_2{\rm Se}_3$. Reversal of the emitted field upon sample inversion and substitution of Pt with W indicates spin‐Hall‐mediated charge conversion, while polarization‐resolved measurements reveal ...

Thickness‐Defined Transport Regime Toward Near‐Ideal Area‐Type Switching
Advanced Materials, EarlyView.By thinning the oxide layer, memristors pass from diode‐like and battery‐effect‐dominated behavior toward eventual short‐circuit failure. Within the intermediate 5–6 nm window, they reach a near‐ideal analog area‐type switching regime, featuring symmetric hysteresis, area‐dependent conductance, and continuous linear programming of HRS and LRS with ...
