Over 250,000 nanoHUB users have run over 7 million simulations in Apps mostly focused on semiconductor devices and materials modeling. nanoHUB created nano-Apps before Apple created Apps for the iPhone and made scientific codes usable for a much larger user group. Most scientific tools strive to be comprehensive in solving “any” simulation problem in a specific problem range. That comprehensiveness limits the use to experts, who require extensive training. nanoHUB has instead focused on delivering a spectrum of Apps (over 700 now) that individually have a limited capability focused on a PN-junction, MOSFET, or nanowire while the underlying tool could of course solve a much wider set of problems. We assembled some of these Apps that are essential for specific courses into small sets such as ABACUS (crystals, bandstructure, drift-diffusion, pn-junctions, BJTs, MOScaps, MOSFETs) [1]. The usability results are stunning. Our user analytics prove that over half of the simulation users participate in structured education through homework/project assignments. We can identify classroom sizes and detailed tool usage [2,3]. We can begin to build mind-maps of design explorations and assess depth of explorations for individuals and classes. While parts of academia struggled to innovate curricula, we have measured the median first-time App insertion into a class to be less than six months. Over 180 institutions have utilized nanoHUB in their curriculum innovation in over 3,600 classes. Over 1 million nanoHUB visitors explore lectures and tutorials annually. Based on this community presence we have expanded nanoHUB towards chip design. Chipshub.org deliver online modeling, simulation, virtual environments, and lectures for the US initiative on workforce development and research funded by the US CHIPSact. Commercial chip design vendors are partnering with Chipshub to host professional chip and semiconductor design software. This presentation will overview some of the nanoHUB impact metrics. In the tutorial a brief overview of ABACUS will be given and the audience may request other tool demonstrations or exploration.

This tutorial serves as an introduction to the electronic properties of DNA and their heterostructures. DNA nanostructures exhibit precise self-assembly capabilities, forming heterostructures with high accuracy. These DNA heterostructures lay the groundwork for proposals involving memory elements, diodes, and resonant tunneling devices, which can emerge from either native DNA or through intercalation processes. We discuss DNA heterostructures of comparable lengths, which show a resistance contrast of nearly two orders of magnitude. Research on electronic transport also suggests the potential for an electrical method to identify short DNA strands, which could be instrumental in disease detection. We will explore the key components involved in modeling these heterostructures and provide an overview of our code for calculating their electronic properties. More recently, the construction of complex heterostructures based on the hybridization of multiple DNA strands has led to the development of 3D DNA nanostructures. These DNA architectures can be assembled into various shapes. We will discuss a recent proposal featuring a nanoscale pore for probing ionic concentration in cells when interfaced with transistors.
Another category of DNA nanostructures involving metal intercalation has been recently proposed by Vecchioni, Canary and Sha. These metal-intercalated structures introduce novel avenues for modulating the electronic properties of DNA. We will discuss the computational pathways for modeling these structures, along with the associated challenges. Modeling these structures necessitates a range of tools, from molecular dynamics to drift-diffusion simulators, depending on the specific features under study.

Electrolysis technologies such as water splitting, CO2 electroreduction, and other emerging reactions, present sustainable alternatives to power large industries such as transport (fuels), manufacturing (chemical feedstock) and agriculture (fertilizers). The viability of these technologies hinges upon achieving sufficient performance in metrics such as product selectivity, productivity (or current density), energy efficiency, and stability, at scale. Conventionally, improvements in these reactions have been sought by tuning the electronic and physicochemical properties of (pre)catalysts through compositional and structural modifications. Here, I will show engineering approaches to tune electrocatalytic activity in water and CO2 electrolysis by manipulating precatalyst reconstruction and reaction environment. I will discuss the need of tailored activation protocols and situ and operando spectroscopies at relevant working conditions to achieve reliability in catalyst design and operation. To conclude, I will overview sustainability issues in the scale up and path to market of CO2 electrolysis technologies.

Gold nanoparticles (AuNPs) are crucial components in a wide range of applications, including catalysis, printed electronics, detecting systems, and intelligent packaging. This is due to their remarkable chemical, physical, and optical capabilities. Historically, the fabrication of AuNPs and their thin films and devices has necessitated intricate processes that demand sophisticated equipment such as mechanical milling, vacuum deposition, and lithography. These methods are primarily employed for expensive devices or small-scale samples. In contrast, solution-based procedures offer a more straightforward and cost-efficient option that is suitable for large-scale production. The speaker will presents a simple in-situ reduction reactive blade-coating method that is suitable for roll-to-roll coating and printing methods. This methodology allows for the production of films containing AuNPs on both rigid and flexible substrates. By manipulating the quantities of reactants and the solvent systems, we are able to create films of gold nanoparticles with different sizes and shapes. This technique facilitates the production of flexible, printable devices using AuNPs technology in a more cost-effective manner, suitable for applications in the fields of electronics, photonics, chemistry, and biomedicine.
