Two-dimensional (2D) chromium telluride Cr2Te3 exhibits strong ferromagnetic ordering with high coercivity at low temperatures and paramagnetic behavior when approaching room temperature. The spin states of monolayer Cr2Te3 show ferromagnetic ordering in the ground state. In situ Raman analysis reveals a reversible structure transformation and hence proves ferromagnetic to paramagnetic transition during low-temperature heating cycles (0–25 °C). The magnetic phase transition near room temperature in 2D Cr2Te3 prompted an exploratory study of these layered materials for energy application. We demonstrate that the low-temperature ferromagnetic behavior can be used to magnetically deice material surfaces using an external magnetic source, avoiding the use of harsh chemicals and high temperatures. The hydrophobic nature and dipole interactions of H2O molecules with the surface of the 2D Cr2Te3 coating aid in the condensation of ice droplets formed on the surfaces. First-principles calculations also confirm the observed crystal structure, surface interaction, and magnetic properties of 2D Cr2Te3.

The influence of asymmetry of plasma sources on the structure and spatial localization of a superthin
current sheet (STCS) supported by demagnetized electrons is studied using a self-consistent model. The
simulation takes into account the presence of a single plasma source in the northern hemisphere, which

The reaction of copper(I) phenylacetylide [PhC ≡ CCu]n with the 2-pyridylphosphines (tBu2PyP and Ph2PyP) offers a straightforward route to structurally diverse clusters. With tBu2PyP, a trinuclear cluster [Cu3(C ≡ CPh)3(tBu2PyP)3] featuring a Cu3 triangular was isolated. Surprisingly, the reaction of [PhC ≡ CCu]n with Ph2PyP yields two isomeric clusters [Cu4(C ≡ CPh)4(Ph2PyP)4] with tetrahedral or zigzag-arranged Cu4 cores. Upon prolonged storage in acetonitrile, the tetrahedral Cu4 cluster converts to ...

Plasmonic nanostructures typically exhibit shifts in their resonant wavelength in response to changes in the refractive index of the surrounding medium. This limits their applications in scenarios requiring stable optical resonances. Here we present a metallic-dielectric hybrid metasurface that exhibits stable multi-wavelength resonance even if the refractive index of its surrounding varies. To quantitatively evaluate the stability of ...

We perform a Monte Carlo analysis of the Ising model on many three-dimensional lattices. By means of finite-size scaling we obtain the critical points and determine the scaling dimensions. As expected, the critical exponents agree with the three-dimensional Ising universality class for all models. The irrelevant field, as revealed by the correction-to-scaling amplitudes, appears to ...

The dipolar [3+2]-cycloaddition reactions of 3-aroylpyrrolo[2,1-c][1,4]benzothiazine-1,2,4-triones with diarylnitrones lead to the formation of benzo[b]isoxazolo[5',4':2,3]pyrrolo[1,2-d][1,4]thiazines. The reac- tion proceeds stereoselectively to form exclusively the (2aS*,3R*,5aS*) diastereomers. Density functional theory computations for the model reaction showed that the (2aS*,3R*,5aS*) diastereomers are both kinetically and thermodynamically preferred over the alternative (2aS*,3S*,5aS*) diastereomers. At room temperature in solution, the ...

Canted antiferromagnets offer great potential in fundamental research and for use in applications due to their unique properties. The presence of the Dzyaloshinskii–Moriya interaction (DMI) leads to the existence of a weak ferromagnetic moment at room temperature.
