Unconventional gas sensing underlies a mixed phase composition of 2D tungsten oxide nanosheets with multiple charge states, which are otherwise inaccessible, generating select catalytic surfaces. Here, we report an unconventional gas‐sensing in oxygen‐deficient WO 3−x . These materials are n‐type phase‐separated metal oxide semiconductors comprised of distinct poorly insulating WO 2.9 domains embedded in the hard insulating WO 2 host, consisting of spatially separated competing phases. Our study highlights the fundamental differences between phase‐separated WO 3−x and WO 3 systems, where WO 3−x exhibits unconventional sensitivity towards NO 2 (−125% at 10 ppm) and CO (94% at 10 ppm), unlike pristine WO 3 (685% at 10 ppm NO 2 and −84% at 10 ppm CO). The WO 3−x sensor shows excellent cross‐sensitivity towards NO 2 and CO, dominated by their chemisorption onto different surface(s) of 2D WO 2.9 and WO 2 nanosheets, validated by theory. The pristine WO 3 sensor exhibits high sensitivity with fast response/recovery times at room temperature, setting records among existing conventional sensors. These results suggest an unknown, possibly novel mechanism is required to explain the unconventional sensing in WO 3−x . Unconventional gas sensing, coupled with cross‐sensitivity and a combination of conventional sensing across a wide temperature range, is desirable for real‐world applications for sensors operating in mixed gas environments.

Angewandte Chemie International Edition, 2025
Organic–inorganic hybrid halides (OIHHs) have gained attention as potential ferroelectric materials due to structure‐property synergy of the organic and inorganic constituents. This study introduces an unusual Ag(I)‐based ternary OIHH, (4,4′‐bpy)Ag2Br4, featuring rotational flexibility in the organic dication to induce asymmetry into the structure. The compound crystallizes in a monoclinic crystal system with a non‐centrosymmetric polar P21 space group at room‐temperature and undergoes a structural phase transition to a centrosymmetric phase (P21/c) at Curie temperature (Tc) of 330 K which was further supported by differential scanning calorimetry (DSC), second harmonic generation (SHG) signals, dielectric anomaly, current‐voltage (I–V) profiles, and X‐ray photoelectron spectroscopy (XPS) data. Ferroelectricity is confirmed through polarization–electric field (P–E) hysteresis loops and piezoresponse force microscopy (PFM), exhibiting switchable polar domains. Density functional theory (DFT) calculations revealed electronic structures of the ferroelectric and paraelectric phases, identified the (β‐AgBr2)nn− inorganic anionic chain contributing to the net polarization, and in general, complemented the experimental results. Comparative studies with structurally analogous Ag(I)‐based OIHHs lacking dication rotational freedom endorse the critical role of organic flexibility in driving ferroelectricity. This study provides insights into the role of organic dications in controlling ferroelectric behavior and offers a promising pathway for developing coinage metal‐based OIHH ferroelectric materials.
Synergistic Photoconductivity and Ultralow Thermal Conductivity upon Stabilizing Iron(III)-tris(2,2′-bipyridine) in a Two-Dimensional Haloargentate Network

Chemistry of Materials, 2025
Crystalline organic–inorganic halometallate hybrids have emerged as promising materials for optoelectronic applications due to their structural diversity and tunable properties. We report a three-dimensional (3D) hybrid organic–inorganic crystal─[Fe(bpy)3]2Ag6Br11·NO3 (bpy = 2,2′ bipyridine)─consisting of two-dimensional (2D) Ag(I)-based (Ag6Br11)n5n– anionic sheets, zero-dimensional (0D) [Fe(bpy)3]3+ complexes (acting as the structure-directing agent), and interlayer disordered NO3– anions. Specifically, the thermodynamically unstable cation [Fe(bpy)3]3+ is stabilized under ambient conditions by the two-dimensional (2D) inorganic anionic scaffold. The crystal exhibits strong ligand-supported argentophilic interactions (Ag···Ag bond distance of 2.98 Å), forming an extended (Ag6Br11)n5n– network, and displays broad UV–visible absorption with a band gap of 1.90 eV. Remarkably, this organic–inorganic hybrid shows a ∼103-fold increase in photocurrent under 532 nm light illumination. Density functional theory calculations provided the mechanistic insights, and such a remarkable photoconductivity is attributed to an efficient charge delocalization and inorganic-to-organic charge transfer. Additionally, the crystal exhibits an ultralow thermal conductivity over a broad temperature range (≈0.3 W/m·K; 300–400 K), making it an excellent candidate for heat management applications.

Graphene Straintronics by Molecular Trapping
Pawan Kumar Srivastava, Vedanki Khandelwal, Indukuru Ramesh Reddy, Kartick Tarafder, Subhasis Ghosh
Journal of Physical Chemistry C, 2025
Here, we report on controlling strain in graphene by trapping molecules at the graphene–substrate interface and leveraging molecular dipole moments. Spectroscopic and transport measurements reveal that strain correlates with the dipole moments of trapped molecules extending beyond their molecular sizes, where values ranging from 1.5 to 4.9D lead to a 50-fold increase in strain and a significant rise in residual carrier density. This has been possible by charge transfer between graphene and trapped molecules, altering the C═C bond length and causing biaxial strain. First-principles density functional theory calculations confirm a consistent dependence of the bending height on molecular dipole moments.
Coexistence of Spin-Polarized Dirac and Weyl Nodes in 2D Electride Ferromagnet Yttrium Iodide
Suneetha N, Ananthram K S, Nirmalya Ballav, Kartick Tarafder
Journal of Physical Chemistry C, 2025
The unique electronic structure of yttrium iodide (YI) has been predicted for the first time, revealing nontrivial topological properties that combine spin-polarized Dirac and Weyl nodes within the same phase. The study identified nodal points present in both spin channels. The existence of Weyl nodes is further confirmed by the source and sink features in the Berry curvature plot and the presence of Fermi arcs in the surface band structure. The electron and hole packets are found to be connected at the Weyl point, classifying YI as a type-II magnetic Weyl semimetal. Under spin–orbit coupling (SOC), eight pairs of Weyl points exhibit robust behavior, while a small band gap forms at the spin-polarized Dirac cone. The system also demonstrates a high Fermi velocity, estimated at about 3.4 × 105 m/s, for Dirac Fermions and a giant anisotropic intrinsic anomalous Hall conductivity of up to 933 S/cm.
High Thermoelectric Figure of Merit (zT) in β-Ag2Se via Aliovalent Doping
Aradhana Acharya, Suneetha Nagaraja, Nahid Hassan, Kartick Tarafder, Nirmalya Ballav
Small, 2025
High‐performance thermoelectric materials are essential for efficient low‐temperature (300–400 K) heat energy harvesting, with n‐type Ag2Se being a promising candidate. To further enhance the thermoelectric figure of merit (zT) of Ag2Se, aliovalent doping has emerged as a key strategy. However, achieving wet‐chemical aliovalent doping of Ag2Se at ambient temperature has proven challenging. In this work, a high zTmax of 1.57 at 398 K is reported for an optimally Cd(II)‐doped Ag2Se sample, specifically in the structurally phase‐pure Ag1.98Cd0.02Se, which is successfully synthesized via an aqueous‐based method at room‐temperature (300 K). The Ag1.98Cd0.02Se sample also exhibits an impressive average zTavg of 1.12 over the temperature range of 315–400 K. Density functional theory (DFT) calculations for both the pristine and doped samples reveal significant changes in the electronic band structures, including notable modulations in the density of states near the Fermi energy, particularly for the Ag‐3d states. The remarkable thermoelectric performance of Ag1.98Cd0.02Se is attributed to an optimization of charge carrier induced by the Cd(II)‐doping.

Physical Review B, 2025
This paper discusses the coupling between spin-wave-mediated magnetic interactions and lattice degrees of freedom in bilayer ${\mathrm{La}}_{1.4}{\mathrm{Sr}}_{1.6}{\mathrm{Mn}}_{2}{\mathrm{O}}_{7}$ (BL-LSMO-0.3). The thermal evolution of the Raman shift, as obtained from micro-Raman spectroscopic measurements over a wide temperature range, reveals the evolution of phonon dynamics while the system undergoes a balance between double and superexchange spin-spin interactions through spin-wave modulation in different magnetic phases. The evolution of relative magnetoelastic coupling strengths for nearest-neighbor ferromagnetic and next-nearest-neighbor antiferromagnetic superexchange interactions in the high-temperature canted antiferromagnetic phases are estimated. We have also demonstrated the existence of orbital ordering and its correlation with spin-phonon dynamics in the canted antiferromagnetic phases of BL-LSMO-0.3 from the detailed analysis of the high-wave-number orbiton-related phonon modes. Our study further reveals the absence of charge ordering in the compound. The complex coupling of lattice distortion, orbital ordering, the nearest- and next-nearest-neighbor spin-spin interactions in determining the canted spin states of the system is discussed.
