If computer scientist and mobile applications developer Arfhan Ahmad has his way, his burgeoning Houston-based startup, QuickPantri, will be directly responsible for adding to the definition of what it truly means to be neighborly.

“Fast delivery from next door” — that’s the tagline for Ahmad’s hyperlocal grocery platform, which focuses on solving last-mile access, neighborhood commerce and food affordability.

“I’m passionate about combining technology with real-world problems, especially those that impact working families and underserved communities,” Ahmad says. “I moved to Houston two years ago, and here I realized that grocery stores are far from the neighborhoods.”

Ahmad envisions QuickPantri will help people who need grocery items urgently, sparing them a trip to the store or costly delivery fees by letting them source items directly from their neighbors’ cupboards.

With his new peer-to-peer app, members — especially those tethered to their residence due to disability or immobility or those unable to make grocery runs with children in tow — can simply log on to QuickPantri and purchase grocery items from their own neighbors.

“My initial thought was, 'What if we have an app that allows people to open a grocery store at their own home and sell any essential items to other neighbors?'” Ahmad says. “So, after having this idea in my mind, I asked my neighbors, 'If I sell groceries from my home, would you buy them from me?' And most of them gave me positive responses. After doing some surveys online on the Nextdoor app and Facebook, I started building this app.”

And like a good neighbor, Ahmad launched QuickPantri in his own neighborhood in Katy.

He then looked at scaling, first by securing approvals from Harris County to sell pre-packaged grocery items from his home. The response exceeded his own expectations. In the last two months, Ahmad estimates that he has delivered to 250 homes in the Katy area. Ahmad has seen that most customers use the app in search of late-night snacks and drinks.

“Ninety-five percent of those orders were delivered in 15 to 30 minutes … Our plan is to expand in other high-risk communities and other cities,” Ahmad says.

To date, Ahmad has obtained approvals from Arizona, Utah and Nevada.

He’s in the process of launching version two. Starting September 1, other sellers will be able to join the app and apply to sell goods to their neighbors. Ahmad says he currently has 50 sellers on the waitlist.

Each seller is allotted a potential selling radius of 10 minutes to ensure swift delivery. Also, sellers are required to deliver the goods via bicycle or on foot, making QuickPantri a pollution-free delivery option.

Currently, the app only sells pre-packaged items and sellers are required to show the expiration date in photos. The app utilizes AI to check pricing for goods in the area, and Ahmad says the app typically lists prices lower than what AI predicts.

Outside of geographic reach and number of buyers and sellers, Ahmad also hopes to expand the list of items that can be sold on the app to include clothes, electronics and cleaning supplies.

“We want our seller to be the ultimate source,” Ahmad says.

How Houston innovators played a role in the historic Artemis II splashdown

safe landing

Research from Rice University played a critical role in the safe return of U.S. astronauts aboard NASA’s Artemis II mission this month.

Rice mechanical engineer Tayfun E. Tezduyar and longtime collaborator Kenji Takizawa developed a key computational parachute fluid-structure interaction (FSI) analysis system that proved vital in NASA’s Orion capsule’s descent into the Pacific Ocean. The FSI system, originally developed in 2013 alongside NASA Johnson Space Center, was critical in Orion’s three-parachute design, which slowed the capsule as it returned to Earth, according to Rice.

The model helped ensure that the parachute design was large enough to slow the capsule for a safe landing while also being stable enough to prevent the capsule from oscillating as it descended.

“You cannot separate the aerodynamics from the structural dynamics,” Tezduyar said in a news release. “They influence each other continuously and even more so for large spacecraft parachutes, so the analysis must capture that interaction in a robustly coupled way.”

The end result was a final parachute system, refined through NASA drop tests and Rice’s computational FSI analysis, that eliminated fluctuations and produced a stable descent profile.

Apart from the dynamic challenges in design, modeling Orion’s parachutes also required solving complex equations that considered airflow and fabric deformation and accounted for features like ringsail canopy construction and aerodynamic interactions among multiple parachutes in a cluster.

“Essentially, my entire group was dedicated to that work, because I considered it a national priority,” Tezduyar added in the release. “Kenji and I were personally involved in every computer simulation. Some of the best graduate students and research associates I met in my career worked on the project, creating unique, first-of-its-kind parachute computer simulations, one after the other.”

Current Intuitive Machines engineer Mario Romero also worked on Orion during his time at NASA. From 2018 to 2021, Romero was a member of the Orion Crew Capsule Recovery Team, which focused on creating likely scenarios that crewmembers could encounter in Orion.

The team trained in NASA’s 6.2-million-gallon pool, using wave machines to replicate a range of sea conditions. They also simulated worst-case scenarios by cutting the lights, blasting high-powered fans and tipping a mock capsule to mimic distress situations. In some drills, mock crew members were treated as “injured,” requiring the team to practice safe, controlled egress procedures.

“It’s hard to find the appropriate descriptors that can fully encapsulate the feeling of getting to witness all the work we, and everyone else, did being put into action,” Romero tells InnovationMap. “I loved seeing the reactions of everyone, but especially of the Houston communities—that brought me a real sense of gratitude and joy.”

Intuitive Machines was also selected to support the Artemis II mission using its Space Data Network and ground station infrastructure. The company monitored radio signals sent from the Orion spacecraft and used Doppler measurements to help determine the spacecraft's precise position and speed.

Tim Crain, Chief Technology Officer at Intuitive Machines, wrote about the experience last week.

"I specialized in orbital mechanics and deep space navigation in graduate school,” Crain shared. “But seeing the theory behind tracking spacecraft come to life as they thread through planetary gravity fields on ultra-precise trajectories still seems like magic."

UH breakthrough moves superconductivity closer to real-world use

Energy Breakthrough

University of Houston researchers have set a new benchmark in the field of superconductivity.

Researchers from the UH physics department and the Texas Center for Superconductivity (TcSUH) have broken the transition temperature record for superconductivity at ambient pressure. The accomplishment could lead to more efficient ways to generate, transmit and store energy, which researchers believe could improve power grids, medical technologies and energy systems by enabling electricity to flow without resistance, according to a release from UH.

To break the record, UH researchers achieved a transition temperature 151 Kelvin, which is the highest ever recorded at ambient pressure since the discovery of superconductivity in 1911.

The transition temperature represents the point just before a material becomes superconducting, where electricity can flow through it without resistance. Scientists have been working for decades to push transition temperature closer to room temperature, which would make superconducting technologies more practical and affordable.

Currently, most superconductors must be cooled to extremely low temperatures, making them more expensive and difficult to operate.

UH physicists Ching-Wu Chu and Liangzi Deng published the research in the Proceedings of the National Academy of Sciences earlier this month. It was funded by Intellectual Ventures and the state of Texas via TcSUH and other foundations. Chu, founding director and chief scientist at TcSUH, previously made the breakthrough discovery that the material YBCO reaches superconductivity at minus 93 K in 1987. This helped begin a global competition to develop high-temperature superconductors.

“Transmitting electricity in the grid loses about 8% of the electricity,” Chu, who’s also a professor of physics at UH and the paper’s senior author, said in a news release. “If we conserve that energy, that’s billions of dollars of savings and it also saves us lots of effort and reduces environmental impacts.”

Chu and his team used a technique known as pressure quenching, which has been adapted from techniques used to create diamonds. With pressure quenching, researchers first apply intense pressure to the material to enhance its superconducting properties and raise its transition temperature.

Next, researchers are targeting ambient-pressure, room-temperature superconductivity of around 300 K. In a companion PNAS paper, Chu and Deng point to pressure quenching as a promising approach to help bridge the gap between current results and that goal.

“Room-temperature superconductivity has been seen as a ‘holy grail’ by scientists for over a century,” Rohit Prasankumar, director of superconductivity research at Intellectual Ventures, said in the release. “The UH team’s result shows that this goal is closer than ever before. However, the distance between the new record set in this study and room temperature is still about 140 C. Closing this gap will require concerted, intentional efforts by the broader scientific community, including materials scientists, chemists, and engineers, as well as physicists.”
