Mendonça,  * Leonardo Tomiatti,  Kleber R. Pirota  and Fanny Bron  *  \nNanoscale advanced materials are crucial for technological innovations. Among them, nanowires stand out due to their promising confinement effects and anisotropic properties derived from their elongated structure. However, this class of nanomaterials remains relatively underexploited, primarily due to fabrication challenges. In this work, we implement an alternative method for preparing nanowire arrays by pressing liquid metal into nanoporous alumina templates with cylindrical pores. Gallium was used asthe liquid metal due to its melting point near room temperature. An investigation exploring the impact of temperature and pressure on the infiltration factor and length of nanowires was performed, revealing some counterintuitive behaviors. Higher filling factors and longer nanowires were obtained at lower infiltration temperatures, closer to the solidification point, with better performance observed at intermediate infiltration pressures rather than at higher pressures. Under optimal conditions, over 10 million parallel Ga nanowires per square millimeter were produced, with an average diameter of 151 + 36 nm and a high aspect ratio of around 500 .  \n1. Introduction  \nAmong nanostructures, nanowires are particularly interesting due to their unidimensional geometry. Their high length-towidth and surface-to-volume ratios enhance properties such as anisotropy and sensitivity in chemical and biological aspects.1 In addition, nanoscale con􀀁nement enables the exploration of signi􀀁cant changes in quantum conditions, including modi􀀁cations in energy level con􀀁gurations.2 Asa result, properties such as magnetism and thermal, electrical, or optical conductivity can differ signi􀀁cantly between the axial and transverse directions. These unidimensional nanoscale characteristics have been extensively studied for various applications.1–3  \nOver the past two decades, semiconductor nanowires with lengths reaching millimeters and diameters limited to hundreds of nanometers have been studied due to the different conducting properties expected for one-dimensional materials.3 Researchers have developed numerous axial and radial nanowire heterostructures, exploring their distinct electronic and photonic properties.4–7 Moreover, nanowires may differ in phonon transport properties compared to their bulk counterparts. For example, silicon nanowires with rough surfaces and approximately 50 nm in diameter demonstrated a 100-fold decrease in thermal conductivity.8 This resulted in a 􀀁gure of  \nInstituto de Fsica Gleb Wataghin, Universidade Estadual de Campinas, 13083-859 Campinas, SP, Brazil.

Furthermore, the 􀀁rst fully integrated nanowire-based system for direct solar water splitting was developed in 2013.9 A few years later, the same research group created a hybrid system combining semiconducting nanowires with S. ovata bacteria, where the nanowires capture sunlight while the bacteria facilitate the conversion of carbon dioxide and water in a synthetic photosynthesis process.10 Beyond thermoelectrics and solar energy conversion and storage, nanowires have also played a signi􀀁cant role in advancing battery materials, piezoelectric technologies, and medical applications, as non-invasive drug delivery.1,11  \nHowever, the preparation of nanosized elongated materials with compositional tunability and high homogeneity remains challenging.
