The development of large-scale metallic systems made of nano-size building blocks holds a key for a new generation of advanced materials, which may lead to breakthroughs in different technological fields including catalysis, photonics, optoelectronic devices, imaging and sensing. Metallic systems are 3D nanoporous networks that do not naturally exist in nature. Metallic systems' preparation methods greatly dictates their performance. The principal strategies for the preparation of nanoporous metals are dealloying, templating, and colloidal assembly. Besides being multi-step preparation techniques, the principal strategies are failing to produce pure material.
We propose a cutting-edge technology for the preparation of large-scale 3D nanoporous metallic networks by a single-step overall physical vapor deposition (PVD) process using electrostatic silica aerogel substrate.
The Commercial Benefit
The technology is applicable for different types of metals and metal-oxide. It allows easily tuning of the geometrical properties of the networks by modifications of PVD conditions, and therefore allows control over the resulted optical and catalytic properties. The nanoporous films are characterized by very low density, optical transparency, plasmonic activity, and conductivity.
The nanoporous metallic networks' higher inner surface-area, multimodal nano-size moieties (particles and cavities), the possibility for hosting guest materials, and their inhomogeneous surface at the sub-micron scale, are all properties which makes them distinct from both conventional metallic nanoparticles and bulk metals. They can be both combined into present technologies to improve existing performances and can be developed as individuals to originate new applications.
The versatility offered by electro optic systems is vital for defense, homeland security, and aerospace segments. The global Electro-Optics market is projected to be $14.03 billion in 2020. Another relevant market is the Infrared Detector Market which is expected to witness a compound annual growth rate of 11.44% to reach a total market size of US$673.501 million by 2023, from US$391.946 million in 2018.

Dr. Adi Salomon
• Dr. Adi Salomon obtained her PhD from the department of Materials and Interfaces at Weizmann Institute of Science with David Cahen. There she got a scientific background on surface chemistry, semiconductors and electron transport through organic molecules.
• Dr. Adi Salomon worked with Thomas Ebbesen, in Strasbourg, on the interaction between molecules and surface plasmons. Dr. Salomon's research was the first to demonstrate the dynamics of interaction between surface plasmons and molecules throughout the development of a new surface photochemistry.
• Later on, at the Weizmann Institute of Science, together with Yehiam Prior, Tamar Seideman, Robert Gordon and Maxim Shukaharev, she developed a new model to explain interactions between molecules that are immersed in the ‘plasmonic field’.
• Salomon's lab, at Bar-Ilan University, is investigating the interaction between molecules at light at the nano scale, and real time imaging of electrodes surfaces as part of INREP group.
