Triggered Ferroelectricity in HfO2 From Hybrid Phonons and Higher‐Order Dynamical Charges
Advanced Materials, Volume 38, Issue 19, 1 April 2026.We combine first‐principles calculations, LGD theory and group theory to demonstrate the mechanism of hybrid‐triggered ferroelectricity in HfO2${\rm HfO}_2$, enabled by trilinear and quadlinear couplings between stable polar and nonpolar modes. HfO2${\rm HfO}_2$ hosts unconventional interplay between structure modes where substantial contribution to ...

Generalized Quadrangles of Order (s, s2), III
Journal of Combinatorial Theory, Series A, 1994 This paper, which is self-contained and does not really depend on part I [ibid. 67, No. 2, 140-160 (1994; Zbl 0592.51003)], studies essentially the finite generalized quadrangles of order \((s,s^2)\), \(s\) odd, which are translation generalized quadrangles.

Wide‐Range Adaptive Metal Oxide for Hydrogen Sulfide Detection From Earth to Space‐Like Environments
Advanced Science, Volume 13, Issue 19, 2 April 2026.This work presents a gas sensing platform based on Cu‐doped SnO2 microspheres that operates reliably from ambient to space‐like conditions. The sensor maintains performance across vacuum and cryogenic environments, bypassing traditional oxygen‐mediated mechanisms, utilizing direct chemisorption and interfacial charge transfer.

Sn Nanostructures Enfolded Nanocarbon Grafted on V2C MXene Anode for Lithium‐Ion Storage
Batteries &Supercaps, Volume 9, Issue 4, April 2026.Sn nanoparticles were enfolded in nanoporous carbon and anchored on delaminated V2C MXene to form a composite for lithium‐ion battery (LIB) anode. This structure intends to mitigate Sn volume expansion and V2C restacking during Li storage. The Sn/C–V2C delivered 553 mAh g−1 at 0.1 C and retained 91% capacity after 500 cycles, outperforming Sn‐carbon ...

International Journal for Numerical Methods in Fluids, Volume 98, Issue 4, Page 448-468, April 2026.The proposed work implements a direct flux reconstruction method for spatial discretization and a stiffness‐resilient exponential time integration method for temporal discretization on the cube‐sphere grid. A space‐time tensor formalism is employed to provide a general representation in any curvilinear coordinate system. This combination enables highly

People and Nature, Volume 8, Issue 4, Page 808-834, April 2026.Abstract Background. Fostering healthy urban living conditions is a critical public health objective. One efficient approach lies in the contact to nature, as numerous studies have shown that urban and peri‐urban natural elements both indoors and outdoors carry a large potential in buffering typical urban threats to mental health.

Small Science, Volume 6, Issue 4, April 2026.Mesopores in SnO2 increase the number of active sites and oxygen vacancies, strengthen intermediate stabilization, and improve structural stability, enhancing CO2 to formate conversion. Electrocatalytic CO2 reduction (CO2RR) into value‐added chemicals represents a promising strategy for sustainable CO2 utilization.
