    Advanced Functional Materials, 2026
    As society seeks alternatives to energy‐intensive manufacturing, biological growth offers an underexplored route for material fabrication. While prior studies have demonstrated direct ink writing of mycelium‐based composites, these approaches often use mycelium only as a structural filler. Here, we exploit active hyphal growth as a post‐printing, growth‐driven functionalization mechanism to self‐assemble particles and tune material properties. When micro‐ and nano‐particles are introduced into the liquid growth medium, their incorporation follows distinct, size‐dependent pathways. Nanoparticles adsorb onto and armor the hyphae, whilst micron‐sized particles become physically entangled within the growing network. By printing inoculated, cross‐linkable hydrogels via direct ink writing, we spatially confine the mycelial architecture without disrupting growth. We introduce selective particle deposition using a dissolvable gelatin mask, enabling localized functionalization. We explore how the shape morphology evolves as the mycelium grows from the hydrogel scaffold into the media. Incorporation of conductive carbon particles enhances the native bioelectric signaling, increasing the signal‐to‐noise ratio by 2.7‐fold and peak amplitude by 9‐fold. Together, these findings establish a growth‐programmable living fabricating strategy, where multifunctional materials can self‐assemble through the natural expansion of living networks.
  • Designer Peptide-PVDF Composite Films for High-Performance Energy Harvesting
    Sourav Patranabish, Sameer Dhawan, V. Haridas, Aloka Sinha
    Macromolecular Rapid Communications, 2022
    Polymers and peptides have recently been considered as promising materials for piezoelectric energy harvesting because of their biocompatibility and enormous design possibility. However, achieving significant output voltages while meeting environmental safety requirements, low-cost and easy fabrication remains a major challenge. Herein, we have fabricated a lipidated pseudopeptide incorporated poly(vinylidene fluoride) (PVDF) composite films. Adding lipidated pseudopeptide (BLHA) increases the electroactive phase content, reaching the maximum for the 2 wt% composite film. The composite film containing 2 wt% BLHA manifests the highest dielectric constant and remnant polarization (Pr ), among others. A piezoelectric energy harvesting device fabricated with this film generates open-circuit output voltages up to 23 V, five times amplified output compared to pure PVDF. To the best of our knowledge, this material is superior among the peptide-based piezoelectric energy harvesters reported in the literature. The device is flexible, durable, low-cost, and sensitive to high and low pressures. It can power up multiple LCD panels when pressed with a finger. The non-covalent interaction between BLHA and PVDF is the reason behind the composites' improved piezoelectric response. Density functional theory (DFT) calculations also support this notion.

  • Nematic twist-bend phase of a bent liquid crystal dimer: field-induced deformations of the helical structure and macroscopic polarization
    Sourav Patranabish, Aloka Sinha, Madhu B Kanakala, C V Yelamaggad
    Journal of Physics Condensed Matter, 2022
    The twist-bend nematic (Ntb) phase is a recent addition to the family of nematic (N) phases of liquid crystals (LCs). A net polar order in the Ntb phase under an external electric field is interesting and it was predicted in several recent theoretical studies. We investigated the field-induced polarization behaviour, dielectric, and electro-optic properties of a bent LC dimer CB7CB in the N and Ntb phases. A threshold-dependent polarization current response was obtained in both the phases under triangular and square-wave input electric fields, existing till frequencies as high as 150 Hz. The polarization switching times were found in ∼1 ms region, especially in the N phase. In the Ntb phase, electric field-induced deformation of the helical structure was observed, like ferroelectric LCs. Dielectric measurements revealed the presence of cybotactic clusters via collective relaxations. The dielectric anisotropy (Δϵ) is negative at the frequencies of polarization measurements. The net polarization resulted from field-induced reorientation of cybotactic clusters and additionally from the field-induced deformation of helical structures in the Ntb phase. We explored the possibility of ionic contributions to the net polarization by synthesizing TiO2 nanoparticles (NPs) dispersed CB7CB LC nanocomposite. Incorporation of the NPs resulted in reduction of the collective order, increase in the ionic impurity content and conductivity, but an extinction of the field-induced polarization response. Our results demonstrate that the net polarization has competing contributions from both ferroelectric-like and ionic origin (up to ∼10 Hz) in the LC phases, but it becomes dominantly ferroelectric-like at higher frequencies.
  • Quantum-dots-dispersed bent-core nematic liquid crystal and cybotactic clusters: Experimental and theoretical insights
    Sourav Patranabish, Yiwei Wang, Aloka Sinha, Apala Majumdar
    Physical Review E, 2021
    We study a quantum-dots (QDs) dispersed bent-core nematic liquid crystalline system in planar geometry and present experimental measurements of the birefringence (Δn), order parameter (S), dielectric dispersion, absorption spectra, and optical textures with attention to variations with temperature. A bent-core liquid crystal (LC) 14-2M-CH_{3} is used as the host material and CdSe/ZnS core-shell type QDs are used as the dopant. The nematic (N) phase of the pristine (undoped) LC 14-2M-CH_{3} contains cybotactic clusters, which are retained by its QDs incorporated LC nanocomposite. Our experimental findings support: (i) reduced orientational order parameter of the QDs dispersed LC system compared to its pristine counterpart at fixed temperatures, (ii) reduced cybotactic cluster sizes due to the incorporation of QDs, and (iii) increased activation energies related to reduced cluster sizes. We complement the experiments with a novel Landau-de Gennes-type free energy for a doped bent-core LC system that qualitatively captures the doping-induced reduced order parameter and its dependence on the properties of the QDs and its variation with temperature.
  • One-dimensional theoretical analysis of coupling and confinement effects on the cybotactic clusters of bent-core nematic liquid crystals
    Sourav Patranabish, Yiwei Wang, Aloka Sinha, Apala Majumdar
    Physical Review E, 2019
    The bent-core liquid crystals (LCs) are highly regarded as the next-generation materials for electro-optic devices. The nematic (N) phase of these LCs possesses highly ordered smectic-like cybotactic clusters which are promising in terms of ferroelectric-like behaviour in the N phase itself. We have studied a one-dimensional (1D) Landau-deGennes model of spatially inhomogeneous order parameters for the N phase of bent-core LCs. We investigate the effects of spatial confinement and coupling (between these clusters and the surrounding LC molecules) on the order parameters to model cluster formation in recently reported experiments. The coupling is found to increase the cluster order parameter significantly, suggesting an enhancement in the cluster formation and could also predict a possible transition to a phase with weak nematic-like ordering in the vicinity of nematic-isotropic transition upon appreciable increase of the coupling parameter {\\gamma}.
