    Advanced Functional Materials, 2026
    Ceramic composites exhibiting the combination of light‐weight, semiconducting behavior, low thermal conductivity, and solid‐state lubrication are crucial for advanced applications in electronics, thermal insulation, and wear‐resistant components, enabling efficient performance under demanding conditions. However, obtaining these functionalities simultaneously in a single material is nontrivial because these properties often require opposing structural and compositional features. Here, the synthesis of spark plasma sintered SiOC‐BN ceramic composite by combining amorphous silicon oxycarbide (SiOC) with crystalline hexagonal boron nitride (h‐BN) is reported. Comprehensive structural and microscopic characterizations confirm the existence of uniformly distributed h‐BN and cubic β ‐SiC phases throughout the bulk material. The composite exhibits a p ‐type semiconducting behavior with nearly isotropic electrical resistivity and low cross‐plane thermal conductivity at room temperature. Mechanical and tribological testing further reveal the excellent strength and solid‐state lubrication under high mechanical loads, with a low coefficient of friction. Comparative structure‐property correlations with individual SiOC and h‐BN ceramics highlights the synergistic effects of the combined phases, contributing to the composite's properties. These findings show the potential of SiOC‐BN ceramic composite as a promising material for future technologies.

    2D materials provide ideal platforms for breakthroughs in both fundamental science and practical, real‐world applications. Despite the broad diversity of 2D materials, most integration efforts have focused on homo/hetero‐structural stacking and Janus structures. In this paper, we introduce “glaphene”—a hybrid of two fundamentally different materials: 2D silica glass and graphene. We propose a metastable hybrid structure based on first‐principles calculations, synthesize it via scalable liquid precursor‐based vapor‐phase growth, and chemically validate the interlayer structure and hybridization using extensive optical and electron spectroscopy, mass spectrometry, and atomic‐resolution electron microscopy. Using probe microscopy, we reveal that electronic cloud redistribution at the interface—beyond conventional van der Waals interactions—drives interlayer hybridization via a strong electronic proximity effect. By reconstructing the energy level diagram of glaphene through both theory and experiment, we show that the combination of semi‐metallic graphene (Eg≈0 eV) and insulating 2D silica glass (Eg, exp≈8.2 eV, Eg, th≈7 eV) results in a semiconducting “glaphene” (Eg, exp≈3.6 eV, Eg, th≈4 eV) formed through out‐of‐plane pz hybridization. This work paves the way for scalable, bottom‐up methodologies to bring interlayer hybridization and its emergent properties to the 2D materials toolbox.
  • A Physics-First, Physics-Gated AI Framework for Verifiable Biofilm Sensing
    Caine K. Shagla, Manoj Tripathi, Bichar Dip Shrestha Gurung, Etienne Gnimpieba Zohim, Venkataramana Gadhamshetty
    Proceedings 2025 IEEE International Conference on Bioinformatics and Biomedicine Bibm 2025, 2025
    The Department of Defense (DoD) faces a significant challenge in the Verification and Validation (V&V) of non-deterministic, opaque AI, limiting the deployment of autonomous sensors. This challenge is acute in complex bio-electrochemical systems like biofilms. Current AI approaches for Electrochemical Impedance Spectroscopy (EIS) are bifurcated: (1) computationally intensive, non-interpretable neural networks, or (2) simplified models reliant on a priori ECM selection. We introduce the “Axiomatic-First Framework,” a three-stage methodology that converts first-principles physics into an auditable edge agent. Stage-1 establishes foundational integrity by using Molecular Dynamics (MD) as a physical constraint to model Nernst-Planck and Butler-Volmer physics, generating a “first-principles” dataset. Stage-2 trains a Physics-Informed Neural Network (PINN) “Teacher” whose loss function enforces the governing PDE residuals, yielding calibrated targets for an Equivalent-Circuit Model (ECM) vector <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\theta=\left[R_{c t}, C_{d l}, Z_{W}\right]$</tex>. Stage-3 deploys a dual-mode “Student” AI: (i) a low-power “Physics-Gated Monitor” and (ii) an on-demand Spiking Neural Network (SNN) “Translator” that recovers <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\theta$</tex> with uncertainty quantification. This architecture provides verifiable parameter recovery and auditable alarms, preserving low-power duty cycling.

    Two-dimensional (2D) graphene and graphene-related materials (GRMs) show great promise for future electronic devices. GRMs exhibit distinct properties under the influence of the substrate that serves as support through uneven compression/ elongation of GRMs surface atoms. Strain in GRM monolayers is the most common feature that alters the interatomic distances and band structure, providing a new degree of freedom that allows regulation of their electronic properties and introducing the field of straintronics. Having an all-optical and minimally invasive detection tool that rapidly probes strain in large areas of GRM monolayers, would be of great importance in the research and development of novel 2D devices. Here, we use Polarization-resolved Second Harmonic Generation (P-SHG) optical imaging to identify strain distribution, induced in a single layer of WS2 placed on a pre-patterned Si/SiO2 substrate with cylindrical wells. By fitting the P-SHG data pixel-by-pixel, we produce spatially resolved images of the crystal armchair direction. In regions where the WS2 monolayer conforms to the pattern topography, a distinct cross-shaped pattern is evident in the armchair image owing to strain. The presence of strain in these regions is independently confirmed using a combination of atomic force microscopy and Raman mapping.

    Solution-processed nanomaterials can be assembled by a range of interfacial techniques, including as stabilizers in Pickering emulsions. Two-dimensional (2D) materials present a promising route toward nanosheet-stabilized emulsions for functional segregated networks, while also facilitating surface energy studies. Here, we demonstrate emulsions stabilized by the 2D materials including the transition metal carbide MXene, titanium carbide (Ti3C2Tx), and develop an approach for in situ measurement of nanosheet surface energy based on emulsion inversion. This approach is applied to determine the influence of pH and nanosheet size on surface energy for MXene, graphene oxide, pristine graphene, and molybdenum disulfide. The surface energy values of hydrophilic Ti3C2Tx and graphene oxide decrease significantly upon protonation of usually dissociated functional groups, facilitating emulsion stabilization. Similarly, pristine graphene and molybdenum disulfide increase in surface energy when their surface functional groups are deprotonated under basic conditions. In addition, the surface energies of these pristine materials are correlated with nanosheet size, which allows for the calculation of the basal plane and edge surface energies of pristine nanosheets. This understanding of surface energies and control of emulsion inversion will allow design of emulsion-templated structures and surface energy studies of a wide range of solution-processable nanomaterials.
  • Anti-corrosion peptide coatings and laser patterning for application on flexible transparent silver nanowire electrodes
    Andrés Seral-Ascaso, Ruth Lahoz, Manoj Tripathi, Katrín L. Elídóttir, Vicente L. Cebolla, Izabela Jurewicz, Alan B. Dalton, Rosa Garriga, Edgar Muñoz
    Progress in Organic Coatings, 2024
    This work describes physicochemical processing strategies to allow the efficient use of oligoglycine-based coatings for corrosion protection of transparent silver nanowire (AgNW) electrodes fabricated on flexible polyethylene terephthalate (PET) substrates. The peptide anti-corrosion coatings consist of two-dimensional amino-terminated oligoglycine peptide assemblies, denoted as tectomers. Tectomer sheets are hydrophobic in nature and act as moisture barrier and protective layer preventing oxidation and degradation of the nanowires when exposed to atmospheric conditions. Moreover, tectomer coatings markedly decrease the AgNW electrode sheet resistance (R s ) by mechanical squeezing of wire-to-wire junctions in the network. Enhanced adhesion of the tectomer coatings to PET was achieved by a simple hydrolysis process that generates carboxyl and hydroxyl groups on the plastic substrate, enabling a strong interaction with the amino groups on the tectomer surface. R s values as low as 29.3 Ω/sq with 94.4 % T were achieved for tectomer-coated AgNW electrodes, which are competitive with commercially available AgNW and ITO electrodes. Finally, peptide-coated AgNW networks on PET substrates were efficiently patterned by a one-step laser ablation process without damaging the substrate, offering promise for their use as components in flexible optoelectronics and touchscreen technologies. • Oligoglycine tectomers act as anti-corrosion organic coatings for AgNW electrode protection on flexible PET substrates. • PET chemical processing improves tectomer adherence, allowing decreased R s values. • Tectomer-coated AgNW electrodes provide competitive R s and T values. • Laser patterning of AgNW/tectomer electrodes facilitates touchscreen applications. • Tectomer coatings provide AgNW corrosion protection under harsh conditions.
  • Texture-Induced Strain in a WS2 Single Layer to Monitor Spin–Valley Polarization

    Nanomaterials, 2024
    Nanoscale-engineered surfaces induce regulated strain in atomic layers of 2D materials that could be useful for unprecedented photonics applications and for storing and processing quantum information. Nevertheless, these strained structures need to be investigated extensively. Here, we present texture-induced strain distribution in single-layer WS2 (1L-WS2) transferred over Si/SiO2 (285 nm) substrate. The detailed nanoscale landscapes and their optical detection are carried out through Atomic Force Microscopy, Scanning Electron Microscopy, and optical spectroscopy. Remarkable differences have been observed in the WS2 sheet localized in the confined well and at the periphery of the cylindrical geometry of the capped engineered surface. Raman spectroscopy independently maps the whole landscape of the samples, and temperature-dependent helicity-resolved photoluminescence (PL) experiments (off-resonance excitation) show that suspended areas sustain circular polarization from 150 K up to 300 K, in contrast to supported (on un-patterned area of Si/SiO2) and strained 1L-WS2. Our study highlights the impact of the dielectric environment on the optical properties of two-dimensional (2D) materials, providing valuable insights into the selection of appropriate substrates for implementing atomically thin materials in advanced optoelectronic devices.
  • Tunable 2D Conjugated Porous Organic Polymer Films for Precise Molecular Nanofiltration and Optoelectronics

    Small, 2024
    Structural design of 2D conjugated porous organic polymer films (2D CPOPs), by tuning linkage chemistries and pore sizes, provides great adaptability for various applications, including membrane separation. Here, four free‐standing 2D CPOP films of imine‐ or hydrazone‐linked polymers (ILP/HLP) in combination with benzene (B‐ILP/HLP) and triphenylbenzene (TPB‐ILP/HLP) aromatic cores are synthesized. The anisotropic disordered films, composed of polymeric layered structures, can be exfoliated into ultrathin 2D‐nanosheets with layer‐dependent electrical properties. The bulk CPOP films exhibit structure‐dependent optical properties, triboelectric nanogenerator output, and robust mechanical properties, rivaling previously reported 2D polymers and porous materials. The exfoliation energies of the 2D CPOPs and their mechanical behavior at the molecular level are investigated using density function theory (DFT) and molecular dynamics (MD) simulations, respectively. Exploiting the structural tunability, the comparative organic solvent nanofiltration (OSN) performance of six membranes having different pore sizes and linkages to yield valuable trends in molecular weight selectivity is investigated. Interestingly, the OSN performances follow the predicted transport modeling values based on theoretical pore size calculations, signifying the existence of permanent porosity in these materials. The membranes exhibit excellent stability in organic solvents at high pressures devoid of any structural deformations, revealing their potential in practical OSN applications.
  • Machine Learning-Assisted Raman Spectroscopy and SERS for Bacterial Pathogen Detection: Clinical, Food Safety, and Environmental Applications
    Md Hasan-Ur Rahman, Rabbi Sikder, Manoj Tripathi, Mahzuzah Zahan, Tao Ye, Etienne Gnimpieba Z., Bharat K. Jasthi, Alan B. Dalton, Venkataramana Gadhamshetty
    Chemosensors, 2024
    Detecting pathogenic bacteria and their phenotypes including microbial resistance is crucial for preventing infection, ensuring food safety, and promoting environmental protection. Raman spectroscopy offers rapid, seamless, and label-free identification, rendering it superior to gold-standard detection techniques such as culture-based assays and polymerase chain reactions. However, its practical adoption is hindered by issues related to weak signals, complex spectra, limited datasets, and a lack of adaptability for detection and characterization of bacterial pathogens. This review focuses on addressing these issues with recent Raman spectroscopy breakthroughs enabled by machine learning (ML), particularly deep learning methods. Given the regulatory requirements, consumer demand for safe food products, and growing awareness of risks with environmental pathogens, this study emphasizes addressing pathogen detection in clinical, food safety, and environmental settings. Here, we highlight the use of convolutional neural networks for analyzing complex clinical data and surface enhanced Raman spectroscopy for sensitizing early and rapid detection of pathogens and analyzing food safety and potential environmental risks. Deep learning methods can tackle issues with the lack of adequate Raman datasets and adaptability across diverse bacterial samples. We highlight pending issues and future research directions needed for accelerating real-world impacts of ML-enabled Raman diagnostics for rapid and accurate diagnosis and surveillance of pathogens across critical fields.
  • Thickness dependent tribological and magnetic behavior of two-dimensional cobalt telluride (CoTe2)

    2d Materials, 2024
    Two-dimensional (2D) layered transition-metal based tellurides (chalcogens) are known to harness their surface atoms’ characteristics to enhance topographical activities for energy conversion, storage, and magnetic applications. The gradual stacking of each sheet alters the surface atoms’ subtle features such as lattice expansion, leading to several phenomena and rendering tunable properties. Here, we have evaluated thickness-dependent mechanical properties (nanoscale mechanics, tribology, potential surface distributions, interfacial interaction) of 2D CoTe2 sheets and magnetic behavior using surface probe techniques. The experimental observations are further supported and explained with theoretical investigations: density functional theory and molecular dynamics. The variation in properties observed in theoretical investigations unleashes the crucial role of crystal planes of the CoTe2. The presented results are beneficial in expanding the use of the 2D telluride family in flexible electronics, piezo sensors, tribo-generators, and next-generation memory devices.
