RadLaunch 2021

Connecting Technology Start-Ups to UV+EB Industry Leaders

“RadLaunch serves as critical support to companies working in the UV/EB space as they take their first steps on the long and challenging road to commercialization. Many companies that have an excellent idea and perhaps early positive lab results are missing the contacts and network that will take them past the concept phase. one of the most valuable things that RadLaunch offers is an introduction to member companies such as material and equipment suppliers and end users that can furnish support and guidance.”

Biomass Derived Chromophores for Radiation Curing

Prof. Jayaraman Sivaguru et al, Bowling Green State University, and Gregory Carroll, Ph.D., NRC Senior Research Associate at the Air Force Research Laboratory

The vibrant colors that enhance Nature’s elegance play a critical role in various chemical and biological processes. Translating these colors, which are dictated by the presence of chromophores, to curing technology is challenging as it requires rational manipulation of excited-state properties.

Jayaraman Sivaguru, Ph.D., the Antonia and Marshall Wilson Professor of Chemistry and Associate Director, Center for Photochemical Sciences, at Bowling Green State University, Ohio, is leading the effort in collaboration with Gregory Carroll, Ph.D., NRC Senior Research Associate at the Air Force Research Laboratory, Sruthy Baburaj, graduate student at Bowling Green and Sheila Asiago, PhD candidate at Bowling Green, as they explore translating biomass derived compounds that can be fine-tuned for radiation curing with both UV and visible light.

The biomass derived compounds are fine-tuned to feature superior photochemical properties than the conventional compounds featuring similar chromophores. Sivaguru’s team is working on translating these novel biomass derived compounds as curing systems with high efficiency.

Mighty Buildings

A construction technology company based in Oakland, California, Mighty Buildings is innovating the construction industry by creating beautiful, affordable and sustainable homes using 3D printing, advanced materials and robotics automation. Co-founders Alexey Dubov, Sam Ruben, Slava Solonitsyn and Dmitry Starodubtsev aim to unlock productivity in construction by combining 3D printing and prefab, making construction more sustainable, efficient and affordable.

The company’s large-scale 3D printers use a proprietary thermoset composite material that the co-founders invented, Light Stone Material (LSM), that can be 3D printed and that hardens almost immediately thanks to a UV-curing process, while also maintaining cohesion between layers to create a monolithic structure. LSM is four times lighter than concrete, has a high thermal resistance and is watertight, sturdy and fire resistant. This 3D printing technology allows Mighty Buildings to produce modular houses and building components much faster than traditional construction.

Mighty Buildings has a near-zero waste production process, preventing 1,100 – 2,000 kg of CO2 emission per 3D printed home. Committed to achieving Net-Zero by 2028, the company is 22 years ahead of the construction industry. Certified under California’s Factory Built Housing program to build units using 3D printing, the company is the first company to achieve certification under the UL 3401 standard for evaluating building structures and assemblies. Mighty Buildings is backed by notable international and Silicon Valley tech investors, including Khosla Ventures, Zeno Ventures and Y Combinator.

Multi-Color Visible Light Additive Manufacturing

Prof. Zachariah Page et al, University of Texas at Austin

A limitation to using high-energy UV/violet light in additive manufacturing is that degradation and attenuation narrow the scope of materials which can be used. While tapping visible light can open the door to more materials – including biological compounds, nanocomposites and materials with multiple structures – the photochemistry required for visible light has had unacceptably slow reaction times.

The research team led by Zachariah A. Page, Assistant Professor in the Department of Chemistry at The University of Texas at Austin, is developing high resolution stereolithographic 3D printing using different colors of low energy visible light to rapidly solidify resins. Key to the research is the team’s formulation of panchromatic photopolymer resins.

It has been shown that X-rays generated by high powered electron beam accelerators (already used for decontamination of mail for the US Postal Service since 2002 and for medical device sterilization) can efficiently convert (meth)acrylate formulations commonly used in radiation curable coatings into functional cured matrices for carbon fiber composites, notably as used in automotive components.

Utilizing visible light will enable “spectral control” – the ability to dictate the chemical reaction that occurs by the color of incident light used. This color-specificity provides the foundation for multicolor additive manufacturing (McAM) that will facilitate the fabrication of multi-material objects with unprecedented precision and functionality.

SoLED POU water disinfection - Team from Tel Aviv University

The population in developing countries have limited access to safe drinking water, causing diseases, poor nutrition, and a daily death rate of over 800 children under 5 years. In these countries most of the population live in rural areas, where there is no proper infrastructure and resources to support continuous water treatment e.g., inadequate or no piping systems, intermittent or no electricity, unskilled personnel for maintenance, and fragmented supply chain.  

Led by Dana Pousty and Prof. Hadas Mamane from the Water Technology lab, Tel Aviv University, with the vision to prevent mortality and improve the health of billions of people in developing countries, SoLED is a solar-powered IoT water disinfection device designated for infrastructure-limited areas as developing rural countries. SoLED is a super-efficient UV-LED reactor based on a patented technology that provides maximum disinfection effect with minimum costs while enabling a solar-powered solution. The reactor could be seamlessly integrated into existing systems to assure virus treatment and lowering maintenance costs or provided as a stand-alone product integrated into any pipe. Our patent enables combining multiple frequencies (wavelengths), to dramatically reduce upfront costs and energy consumption and enhance the bacteria inactivation.

UV based filterless personal protection equipment - Open Source Project by HelpfulEngineering.org

UVisor is the world’s first filterless full face protection against COVID-19 and future biological threats, built as a fully-integrated, compact, battery operated and lightweight positive-air-pressure visor powered by a UV sterilization chamber. A technology demonstrator of the UVisor UV Chamber achieved >99.7% efficacy in testing by Sandia National Laboratories against MS2 surrogate virus. The UVisor has several design advantages over conventional masks including better protection, full face visibility, better comfort, and 100% reusability. Being filter-less also gives the UVisor several design advantages over currently available powered respirators – lighter, quieter, cheaper, and no bio-disposal or waste concerns, and by using UV for sterilization no consumable parts. The UVisor technology is also envisioned to be used for many other purposes including exhaled air purification, vent exhaust purification and other sterilization.

A portable device to measure hydroxyl radical scavenging capacity in water samples - Team from the University of Toronto

The hydroxyl radical scavenging capacity of a water to be treated influences the effectiveness of advanced oxidation processes. Conventional methods for its measurement are time-consuming and need sophisticated instrumentation and expertise to carry them out. Chengjin Wang at the University of Toronto collaborated with Erik Rosenfeldt at Hazen and Sawyer to create a novel “external calibration” method to conduct fast and robust measurements of this parameter. The method is now being developed into a simple portable monitoring device that will empower the treatment plant to understand the variation of the scavenging capacity of water on a regular basis so that they can adopt corresponding measures to adjust and optimize their operation.
