Engineering student helps federal experts solve a messy 3D printing problem

Posted by in categories: 3D printing, engineering

Tomographic 3D printing is a revolutionary technology that uses light to create three-dimensional objects. A projector beams light at a rotating vial containing photocurable resin, and within seconds the desired shape forms inside the vial. The light projections needed to solidify specific 3D regions of the polymer are calculated using tomographic imaging concepts.

The technology was first demonstrated by researchers at the University of California, Berkeley and Lawrence Livermore National Labs in 2019, and a Swiss group at École Polytechnique Fédérale de Lausanne (EPFL) in 2020. It is significantly faster than traditional 3D printing in layers, can print around existing objects, and does not require support structures.

Though incredible, the technology can get messy in the lab. The vial’s round shape makes it refract rays like a lens. To counter this, experts use a rectangular index-matching bath that provides a flat surface for rays to pass through correctly. The vial of resin must be dipped in and out of the bath for each use—creating a slimy situation.

New algorithm uses a hologram to control trapped ions

Posted by in categories: computing, engineering, holograms, information science, quantum physics

Researchers have discovered the most precise way to control individual ions using holographic optical engineering technology.

The new technology uses the first known holographic optical engineering device to control trapped ion qubits. This technology promises to help create more precise controls of qubits that will aid the development of quantum industry-specific hardware to further new quantum simulation experiments and potentially quantum error correction processes for trapped ion qubits.

“Our algorithm calculates the hologram’s profile and removes any aberrations from the light, which lets us develop a highly precise technique for programming ions,” says lead author Chung-You Shih, a Ph.D. student at the University of Waterloo’s Institute for Quantum Computing (IQC).

Katherine Sizov — Strella Biotech — Bio-Sensing To Reduce Food Waste And Optimize Supply Chains

Posted by in categories: biotech/medical, chemistry, engineering, food

Novel bio-sensing technologies to reduce food waste and optimize supply chains — a US$1 trillion need — katherine sizov — founder, strella biotechnology.


An estimated 40% of all global produce is wasted due to spoilage that occurs before it ever reaches consumers’ grocery bags. And this loss, not only represents loss due to quality or ripeness standards that consumers desire, but also a significant impact on global emissions and fresh water supplies that it took to produce and transport that produce, representing a combined figure of US$1 Trillion annually.

More Compact and Efficient Vertical Turbines Could Be the Future for Wind Farms

Posted by in categories: computing, engineering, mathematics, sustainability

The now-familiar sight of traditional propeller wind turbines could be replaced in the future with wind farms containing more compact and efficient vertical turbines.

New research from Oxford Brookes University has found that the vertical turbine design is far more efficient than traditional turbines in large-scale wind farms, and when set in pairs the vertical turbines increase each other’s performance by up to 15%.

A research team from the School of Engineering, Computing and Mathematics (ECM) at Oxford Brookes led by Professor Iakovos Tzanakis conducted an in-depth study using more than 11500 hours of computer simulation to show that wind farms can perform more efficiently by substituting the traditional propeller-type Horizontal Axis Wind Turbines (HAWTs), for compact Vertical Axis Wind Turbines (VAWTs).

Skin and bones repaired by bioprinting during surgery

Posted by in categories: bioprinting, biotech/medical, engineering

Fixing traumatic injuries to the skin and bones of the face and skull is difficult because of the many layers of different types of tissues involved, but now, researchers have repaired such defects in a rat model using bioprinting during surgery, and their work may lead to faster and better methods of healing skin and bones.

“This work is clinically significant,” said Ibrahim T. Ozbolat, Hartz Family Career Development Associate Professor of Engineering Science and Mechanics, Biomedical Engineering and Neurosurgery, Penn State. “Dealing with composite defects, fixing hard and at once, is difficult. And for the craniofacial area, the results have to be esthetically pleasing.”

Currently, fixing a hole in the skull involving both and soft tissue requires using bone from another part of the patient’s body or a cadaver. The bone must be covered by soft tissue with , also harvested from somewhere else, or the bone will die. Then surgeons need to repair the soft tissue and skin.

Why small planes still use leaded fuel decades after phase-out in cars

Posted by in categories: energy, engineering, government, policy, transportation

While leaded gasoline was fully phased out in 1996 with the passage of the Clean Air Act, it still fuels a fleet of 170000 piston-engine airplanes and helicopters. Leaded aviation fuel, or avgas, now makes up “the largest remaining aggregate source of lead emissions to air in the U.S.,” according to the Environmental Protection Agency.


Meanwhile residents continue to live with the air quality that comes with living near an airport where small planes burning leaded fuel fly in and out, said Alarcon, who is also a volunteer organizer with the nonprofit tenant advocacy group Vecinos Activos. It’s also unclear to air quality experts and residents what is arguably safe.

“There is no bright line that says ‘Above this concentration lead is safe and below this concentration’ that it is not. You’d have to make a policy decision,” said Jay Turner, an engineering education professor at Washington University in St. Louis and member of the EPA’s Science Advisory Board. “We’re really careful to come back to this point that just because public areas might meet the EPA standard [for lead] doesn’t mean zero risk or zero concern.”
