Graduate’s startup takes top prize at veterans pitch competition

A 10-week journey for a cohort of veterans, current service members and their spouses participating in a small business accelerator program came to a close on May 13.

Members of Cohort 13 in the Michigan Veteran Entrepreneur-Lab, a program of the Richard M. and Helen DeVos Center for Entrepreneurship & Innovation, gave their final pitches to a panel of judges, family and friends at the L. William Seidman Center as part of the MVE-Lab’s Pitch and Showcase.

At stake for the seven entrepreneurs was $20,000 in seed funding for their startups. 

By the end of the night, it was Spencer Scarber and his startup, Emergency Medicine Innovations , taking home the coveted $10,000 first place award as determined by the judges. Emergency Medicine Innovations develops portable cold storage technology and containers suitable for transporting blood or plasma without worry of contamination. 

“ The big issue is that our troops are dying out in the field,” Scarber said. “People aren’t getting the blood or medication they need here and pharmaceutical companies are losing a lot of money, $35 billion to be exact, because they can’t keep things cold.”

Scarber, an airman first class in the Michigan Air National Guard and a 2022 graduate of Grand Valley with a degree in mechanical engineering, said the inspiration for his invention came from his time as an EMT technician prior to enrolling at Grand Valley. 

“ During my clinical rotations, one of the things that I noticed was the big beefy coolers that we have, and they’re bolted to the inside of the ambulance,” Scarber said. “So, if you arrive at a car crash, there’s no easy way to lug this thing directly to the scene of an incident.

“Having something that’s a grab-and-go factor, that’s where the idea came from, but it really just blossomed into determining what customers need.”

Scarber’s technical advisor at EMI is a former professor of his, Sanjivan Manoharan, associate professor of mechanical engineering. 

“ If you ask any student who has had him or even anybody who’s heard of him, he is hands down one of the best professors at Grand Valley,” Scarber said. 

“During my senior year, I did an independent study under him and we performed some computational fluid dynamics to really make sure that our technology was as good as we said it was.”

Scarber’s winning idea embodies the approach to entrepreneurship that Michael Hyacinthe, the lead instructor with the MVE-Lab, viewed with each cohort. 

“Veterans are very community focused, so a lot of their solutions are based on problems that they’ve experienced themselves or they’ve known someone in service that experienced an issue,” Hyacinthe said. 

“Just seeing the passion and the joy as they figure out how to solve their own problems by themselves, but also serving other veterans who are going through those same problems, makes it very rewarding.”

GVSU hosts Americas Competitiveness Exchange delegation

Grand Valley hosted the Americas Competitiveness Exchange (ACE), a delegation of economic development leaders from around the globe, at the Shape Corp. Innovation Design Center (IDC) on the Pew Grand Rapids Campus Wednesday.

The event was part of a series of stops for ACE in Michigan with other locations including Ann Arbor, Battle Creek and Lansing.

After the delegation received a tour of the IDC building and viewed a demonstration of a robot created by Hopkins High School students, President Philomena V. Mantella gave her opening remarks to the group of over 50 ACE delegates.

An engineering and computing panel followed Mantella’s opening statement. The panel featured Paul Plotkowski, dean of the Padnos College of Engineering, Jonathan Engelsma, professor of computing and director of GVSU’s Applied Computing Institute, and Marouane Kessentini, the first appointed dean of GVSU’s newly-formed College of Computing.

The panel discussed the importance of applied research and experiential learning through cooperative education and internships.

“The cooperative education program means that the students do three semesters of work experience,” said Plotkowski. “That experience lays the groundwork for our senior project programs that are deliverable due to products, automation and the list goes on.”

The panel highlighted how this model prepares students for careers with applicable experience sooner than the norm. Engelsma noted students are starting their internships as early as sophomore year instead of what he noticed was the more typical final semester of senior year.

Glendon Ashby, an ACE delegate from Barbados, described building this connection between industry and university as innovative. He said the model can be used to solve problems while expanding opportunities to those who are still gaining experience.

“It just goes to show that when people collaborate what can happen,” said Ashby. “We can bring all the players to the table to ensure that they are making a better pathway to the future.”

Grand Valley, Hauenstein Center part of coalition to host debates this fall

A coalition of universities and civic and economic organizations aim to host a series of regional debates to help voters gain a deeper understanding on the policies and platforms from candidates seeking statewide office.

As a member of the Michigan Debate Task Force, Grand Valley and the Hauenstein Center for Presidential Studies will host one of the regional debates on September 12.  

Megan Rydecki, director of the Hauenstein Center, said the debates will be centered on Michigan voters and require each candidate to elaborate and expand on their message and vision for the state. With the looming retirement of Sen. Debbie Stabenow, one of Michigan’s U.S. Senate seats will become available, creating an opportunity for the task force’s plan to be set in motion.

“In order to maintain the integrity of the democratic process, we think it’s really important for voters to hear directly from candidates about the issues that are most pressing, beyond just sound bites,” Rydecki said.

“It’s key that people actually hear platforms, ideas and plans of attack for how we tackle some of the challenges in our communities and make our state and nation better.”

Each debate will address issues important to the state’s residents but also focus on issues specific to the host region. Along with the debate at Grand Valley, the northern Michigan debate in Traverse City is scheduled for October 10 while the southeast Michigan debate in Detroit is scheduled for October 22.

“It’s critical that voters get valuable information from the candidates directly that they can use to inform how they want to vote,” Rydecki said. “It’s even more so this year as we deal with the effects of artificial intelligence and disinformation, and people not knowing where to go to get information because they don’t know whether or not it’s true.”

The Michigan Debate Task Force includes: the Detroit Economic Club, the Economic Club of Traverse City, the Grand Rapids Chamber, Grand Valley State University, The Hispanic Center of West Michigan, the Northern Michigan Chamber Alliance, Northwestern Michigan College, Oakland University, the Urban League of Detroit and Southeast Michigan and the Urban League of West Michigan.

K-12 students exhibit environmental projects at Groundswell showcase

Since the end of the pandemic, Pinery Park in Wyoming has become a classroom for Godwin Heights Middle School teacher Bill Mull and his sixth grade science class and the school’s Green Club.

Mull’s class has explored and studied a variety of topics pertaining to the environment — water quality, invasive species and wildlife — thanks to the help of GVSU’s Groundswell Stewardship Initiative . 

“We just want to get the students to be excited and develop an understanding of what kind of impact they can have on the environment,” Mull said. “We want them to know how they can be involved in stewardship and take part in helping out the environment. There are actions that they can take that have meaningful effects for the ecosystem.”

Mull’s class and other Grand Rapids area K-12 students unveiled their work at the annual Groundswell Student Project Showcase at the DeVos Center on the Pew Grand Rapids Campus this week. Groundswell provides resources to help teachers engage their students through place-based educational opportunities guiding toward environmental stewardship.

USTC reveals the mystery of the origin and early evolution of nitrogen on earth

Recently, Special Professor Wang Wenzhong of the School of Earth and Space Sciences at the University of Science and Technology of China collaborated with international scholars to conduct an in-depth study of the fractionation behavior of nitrogen isotopes during the accretion and evolution of Earth-like planets using first-principles calculation methods. This study reveals that the two key stages of melting volatilization of early star embryos and late accretion of volatile-rich materials jointly determine the abundance of nitrogen in the silicate Earth, providing new insights into the origin of volatiles on the Earth. Related results Published in “Nature Communications” under the title “Early planetesimal differentiation and late accretion shaped Earth’s nitrogen budget”.

Nitrogen is one of the basic elements of life on earth and is widely present in many organic molecules. Although nitrogen is essential for life, the current silicate Earth (including atmosphere, crust, and mantle) has relatively low nitrogen content, about 2 ppm (two parts per million), compared with the material on which the Earth originally accreted. In-depth study of the accretion and evolution history of nitrogen in the earth is of great significance to understanding the origin of life-related elements on earth and the evolution of habitability.

Currently, there are two main models of volatile accretion on the earth in academia. The first model, the “Late veneer model”, believes that the initial accretionary materials that formed the Earth contained almost no volatiles, including nitrogen, and that the current abundance of volatiles on the silicate Earth was mainly in the late accretion period. Formed by adding small amounts of volatile-rich materials such as carbonaceous chondrites. The second model, the “early evolution model”, believes that the earth’s initial accretion materials were originally rich in volatiles, and a series of evolutionary processes that the earth has experienced have led to the current loss of volatiles in the silicate earth relative to the initial components.

Nitrogen has two stable isotopes, 14N and 15N . Nitrogen isotopes can be used to trace the evolutionary history of Earth’s volatiles during the process of planetary accretion, providing a key research method for studying the origin and evolution of volatiles in terrestrial planets. However, to effectively use this tool, we must first understand the fractionation mechanism of nitrogen isotopes in the early stages of planetary evolution. Distinguished Professor Wang Wenzhong used first-principles calculation methods to study the nitrogen isotope fractionation in the process of nebula material condensing to form star embryos, including two stages: melt volatilization and core-mantle differentiation. The study found that under the condition that hydrogen in the early solar system nebula had not yet completely dissipated, melt volatilization enriched the star embryo with 14N , while core-mantle differentiation led to the enrichment of 15N in silicate melts.

Combining the results of first-principles calculations with actual observational data, the research team found that the early star embryo evolution process is not sufficient to explain the current nitrogen isotope composition of the silicate Earth. A certain amount of volatile-rich substances, such as carbonaceous chondrites, must be added in the late stage of accretion to explain the observed nitrogen isotope characteristics. Therefore, the nitrogen abundance in the silicate Earth is the result of the combined effects of early star embryo evolution and the late accretion stage. It is worth noting that although late accretion has a significant impact on the nitrogen abundance of the silicate Earth, due to the extremely low mass of the added volatile-rich substances, its contribution to the abundance of other volatiles in the silicate Earth is very limited.

The first and corresponding author of the paper is Distinguished Professor Wang Wenzhong, and his collaborators include Professor John Brodholt of University College London, Researcher Michael Walter of the Carnegie Institution for Science, and Professor Huang Shichun of the University of Tennessee, Knoxville.

In recent years, the research team led by Professor Wang Wenzhong has focused on the origin and early evolution of volatile components of terrestrial planets. They have used a variety of isotopes as tracer tools, combined with first-principles calculations and observational data, to reveal the origin of the Earth’s initial accretion. During this stage, a large number of volatile elements were significantly accreted, and the evolution process of the star embryo reshaped the earth’s volatile reservoir. Relevant papers were published in “Nature Geoscience” and “Science Advances” (Wang et al., 2021, NG, 2023, SA). The study is an important addition to existing theoretical models, reassessing the impact of “late accretion” on Earth’s nitrogen abundance. This series of work reveals the comprehensive impact of the two stages of “early evolution” and “late accretion” on the earth’s volatile components, providing a new perspective for understanding the evolutionary history of the earth’s volatile components.

USTC has made new progress in the research of sintering-induced grain boundary Cu/Y catalyst to achieve efficient CC coupling

Recently, the research team of Professor Zeng Jie of the Hefei National Research Center for Microscale Physical Sciences and the Department of Chemical Physics of the University of Science and Technology of China has made important breakthroughs in the synthesis and application of Cu-based catalysts. They developed a molecular sieve-supported Cu-based catalyst that formed grain boundary-rich sites through in-situ sintering. These grain boundary sites enable efficient CC coupling, opening up new opportunities for the production of liquid fuels and valuable chemicals. new path. This result was recently published in Angew. Chem. Int. Ed. under the title “The Importance of Sintering-Induced Grain Boundaries in Copper Catalysis to Improve Carbon-Carbon Coupling”. The first author of the article is a special associate researcher of our school. Wu Wenlong and Luo Lei, the corresponding authors are Associate Professor Li Hongliang and Professor Zeng Jie.

The Fischer-Tropsch synthesis reaction is a key technology for converting coal, natural gas or biomass into liquid fuels and valuable chemicals. The reaction needs to be carried out under harsh reaction conditions of high temperature and pressure, and the catalyst faces the problem of easy sintering. Generally, the sintering of the catalyst will lead to the reduction of the active surface area, thereby reducing the catalytic performance, and is considered a negative factor. However, the study found that the nanoparticles may also induce the formation of new active sites such as grain boundaries during the sintering growth process. Structural perturbation near grain boundaries can induce lattice strain and affect the adsorption process between active sites and reactants and intermediates, thereby improving catalytic performance. Therefore, studying the influence of grain boundaries generated in situ during the reaction on catalytic performance is expected to open a new window for understanding and even utilizing the sintering process.

Traditionally, the main product of Cu-based catalysts is methanol, while Cu/Y catalysts rich in grain boundaries achieve higher selectivity for C 5+ long-chain hydrocarbons in Fischer-Tropsch synthesis reactions. Under the conditions of 300 o C, 20 bar, H 2 :CO=1.5:1, 2,400 mL h -1 g cat -1 , the C 5+ selectivity of the Cu/Y catalyst reached 65.3 C% after an induction period of 40 hours . The CO conversion rate increased sharply from 3.3% to 10.2% during the induction period (Fig. 1a). In addition, the product distribution also experienced significant changes during the induction period, with the hydrocarbon distribution changing from short-chain hydrocarbons to long-chain hydrocarbons and reaching a stable state after 40 h of reaction. Among them, the selectivity of C 5+ hydrocarbons increased from 30.6 C% to 65.3 C%, while the selectivity of methane decreased from 19.3 C% to 10.5 C% and the selectivity of C 2-4 hydrocarbons decreased from 50.1 C% to 24.2 C% (Fig. 1b). The catalyst that reached steady state was treated as a new catalyst, and when the catalytic test was performed again, the catalytic performance remained basically unchanged within 40 hours (Figure 1c). In addition, the selectivity of C 5+ hydrocarbons shows a volcano-shaped relationship with the Cu loading, and the optimal loading is 5wt% (Figure 1d).

(b) Relationship between product distribution, carbon number and reaction time of fresh catalyst. (c) The catalytic performance of the activated catalyst changes with time. d) Performance comparison chart of catalysts with different Cu loadings.

In order to study the reason for the existence of activation period in catalytic performance, the researchers collected samples at different stages of the reaction (2 hours, 10 hours and 40 hours in Figure 1a) for structural evolution characterization. Through spherical aberration electron microscopy, it was found that after 2 hours of reaction in a syngas atmosphere, the catalyst formed larger rice particles with grain boundaries through the mutual aggregation of small particles (Figure 2a and b). As the reaction time prolongs, the particles gradually become larger and the number of grain boundary sites gradually increases (Figure 2c-f). With the help of fast Fourier transform (FFT) images, it was found that there are different crystal planes at the interface (Figure 2g1-g12). Through statistical calculations, the researchers found that grain boundary density is positively correlated with C 5+ selectivity (Figure 2h-j). In order to exclude the influence of molecular sieves and confirm the CC coupling effect at the grain boundary, the researchers loaded the Cu nanoparticles obtained by controlled synthesis onto an inert SiO 2 carrier, and also found that they had high C 5+ selectivity (Figure 2n) . The above results indicate that Cu grain boundary sites play a decisive role in CC coupling.
