Special Issue Information

Dear Colleagues,

In the ever-evolving landscape of materials science, nanomaterials present a transformative frontier, redefining the way we harness energy and understand the fundamental properties of matter. We are thrilled to launch a groundbreaking Special Issue delving into the captivating world of “Thermal, Electrical and Thermoelectric Properties of Nanomaterials and Their Applications”.

Over the years, nanomaterials have taken centre stage in scientific exploration and technological innovation. Their story is one of remarkable progress and scientific curiosity, dating back to the dawn of the nanoscience era. With roots in the discovery of new materials and advances in microscopy, nanomaterials have grown from an academic curiosity to a focal point in materials science, with a vast array of applications across diverse fields. This Special Issue retraces their significant milestones, charting the trajectory of nanomaterials’ journey from the lab to the market.

Our primary aim with this Special Issue is to offer a comprehensive snapshot of the latest breakthroughs and innovations in the field of nanomaterials, focusing on their thermal, electrical, and thermoelectric properties. We expect contributions encompassing a wide range of topics, from the synthesis of novel nanomaterials to pioneering research on the manipulation of thermal conductivity, the enhancement of electrical conductance, and the optimization of thermoelectric efficiency.

Our vision is to create a comprehensive mosaic of the field, offering a multidimensional view of nanomaterials focused on thermal management and thermoelectric applications. As such, we invite a diverse array of contributions, including original research articles, reviews, and perspective pieces which address, but are not limited to, the following themes:

  • The synthesis and characterization of nanomaterials with tailored thermal properties;
  • Advances in thermal management using nanomaterials;
  • Innovations in thermoelectric materials and devices;
  • Theoretical models and simulations for predictive nanomaterial design;
  • Emerging trends and prospects in the field.

Piezoelectric materials are fundamental elements in modern science and technology due to their unique ability to convert mechanical and electrical energy bidirectionally. They are widely employed in sensors, actuators, and energy-harvesting systems. In this work, we investigate the behavior of commercial lead zirconate titanate (PZT) sensors under frequency-mode excitation using a combined approach of impedance spectroscopy and optical interferometry. The impedance spectra reveal distinct resonance–antiresonance features that strongly depend on geometry, while interferometric measurements capture dynamic strain fields through fringe displacement analysis. The strongest deformation occurs near the first kilohertz resonance, directly correlated with the impedance phase, enabling the extraction of an effective piezoelectric constant (~40 pC/N). Moving beyond the linear regime, laser-induced excitation demonstrates optically driven activation of piezoelectric modes, with a frequency-dependent response and nonlinear scaling with optical power, characteristic of coupled pyroelectric–piezoelectric effects. These findings introduce a frequency-mode approach that combines impedance spectroscopy and optical interferometry to simultaneously probe electrical and mechanical responses in a single setup, enabling non-contact, frequency-selective sensing without surface modification or complex optical alignment. Although focused on macroscale ceramic PZTs, the non-contact measurement and activation strategies presented here offer scalable tools for informing the design and analysis of piezoelectric behavior in micro- and nanoscale systems. Such frequency-resolved, optical-access approaches are particularly valuable in the development of next-generation nanosensors, MEMS/NEMS devices, and optoelectronic interfaces where direct electrical probing is challenging or invasive.
