Ferroelectric, Switchable Dielectric and Nonlinear Optical Properties in Inorganic-Organic Lead-Free 1D Hybrids Based on Bi(III) and Azetidine: (CNH)[BiCl], (CNH)[BiBr].

This study investigates lead-free organic-inorganic hybrids (CNH)[BiCl] () and (CNH)[BiBr] (), focusing on their structural, dielectric, ferroelectric, and optical properties. Both compounds exhibit paraelectric () to ferroelectric () phase transitions (PTs) at 230/233 K and 228/229 K, respectively, transitioning from orthorhombic () to monoclinic (2) phases, with distorted [BiX] octahedra forming 1D chains. Quasielastic neutron scattering and solid-state H NMR studies reveal the localized motion of azetidinium cations.

An Online Survey of Technology Use Among Patients With Cancer Aged 65 Years or Older.

Background: Historically, people aged 65 years or older have been slower to adopt new technology. However, technology use in this demographic continues to increase.

Objectives: This study aimed to understand how patients with cancer who are aged 65 years or older engage with technology and whether patient behavior related to technology use has changed because of the COVID-19 pandemic.

Structural, Electric and Dynamic Properties of (Pyrrolidinium)[BiI] and (Pyrrolidinium)[SbI]: New Lead-Free, Organic-Inorganic Hybrids with Narrow Band Gaps.

Hybrid organic-inorganic iodides based on Bi(III) and Sb(III) provide integrated functionalities through the combination of high dielectric constants, semiconducting properties and ferroic phases. Here, we report a pyrrolidinium-based bismuth () and antimony () iodides of (NCH)[MI] (M: Bi(III), Sb(III)) formula which are ferroelastic at room temperature. The narrow band gaps (~2.

Progressive Structural Complexity in Ferroelectric 1,2,4-Triazolium Hexabromoantimonate(III): Interplay of "Order-Disorder" and "Displacive" Contributions to the Structural Phase Transitions.

Halobismuthates(III) and haloantimonates(III) with the RMX chemical composition create a new and broadly unexplored class of ferroelectric compounds. In this paper, we report the haloantimonate(III) ferroelectric comprising an aromatic (1,2,4-triazolium) cation, i.e.

Spatiotemporal Studies of the One-Dimensional Coordination Polymer [Fe(ebtz) (C H CN) ](BF ) : Tug of War between the Nitrile Reorientation Versus Crystal Lattice as a Tool for Tuning the Spin Crossover Properties*.

Reaction of 1,2-di(tetrazol-2-yl)ethane (ebtz) with Fe(BF ) ⋅6 H O in different nitriles yields one-dimensional coordination polymers [Fe(ebtz) (RCN) ](BF ) ⋅nRCN (n=2 for R=CH (1) and n=0 for R=C H (2) C H (3), C H (4), CH Cl (5)) exhibiting spin crossover (SCO). SCO in 1 and 3-5 is complete and occurs above 160 K. In 2, it is shifted to lower temperatures and is accompanied by wide hysteresis (T =78 K, T =123 K) and proceeds extremely slowly.
