Challenging Conventional Wisdom: New Discovery Transforms Our Understanding of Crystals

Posted by in categories: engineering, nanotechnology, particle physics, space

For many, the word “crystals” conjures images of shimmering suncatchers that create a prism of rainbow colors or semi-transparent stones thought to possess healing abilities. But in the realm of science and engineering, crystals take on a more technical definition. They’re perceived as materials whose components – be it atoms, molecules, or nanoparticles –are arranged regularly in space. In other words, crystals are defined by the regular arrangement of their constituents. Familiar examples include diamonds, table salt, and sugar cubes.

Engineering world-changing materials: Nicola Spaldin on the importance of curiosity-driven research and what it means to be a physicist

Posted by in categories: biotech/medical, engineering

When Nicola Spaldin began studying natural sciences at the University of Cambridge in 1988, she planned on becoming a physicist, but then quickly reconsidered. “After about the second lecture I completely changed my mind,” she recalls. “I thought ‘I’m absolutely not clever enough to be a physicist.’ Everybody was very brilliant and I was not.”

Yet it seems Spaldin was vastly underestimating herself. Now a professor of materials science at ETH Zurich, she won two major awards for physics last year: the EPS Europhysics Prize and the Hamburg Prize for Theoretical Physics. Both accolades cited Spaldin’s pioneering work on the theory of magnetoelectric multiferroics – materials that are both ferromagnetic and ferroelectric. These properties are rarely found together, making it very difficult to engineer substances with both, but they have many exciting potential applications, from microelectronics to medicine.

The Materials of Future Transistors

Posted by in categories: computing, engineering

Researchers in the Andrew and Erna Viterbi Faculty of Electrical and Computer Engineering have demonstrated control over an emerging material, which they consider as a possible future alternative to silicon in microelectronics. This is a timely development, because scientists and engineers face challenges in continuing the transistor shrinking trend, an important driver of computer chip performance.

The continuous performance improvement of these chips has been driven by shrinking the size of the most basic logic “Lego” piece – the transistor. Transistors are miniature switches that control the flow of electric currents, analogous to a faucet controlling the flow of water. Already in the early 1960s, Gordon Moore, the founder of Intel, proposed that the transistors’ miniaturization rate should allow doubling of the number of transistors per area every 2 years.

Why Hardware And Software Synergy Is The Key To Driving The Future Of Innovation

Posted by in categories: chemistry, engineering, transportation

This benefits customers by accelerating access to future vehicles that feature the latest technology while also enabling their current vehicles to be eligible to receive updates and improvements over time—unlocking additional value beyond the initial point of purchase. And for large enterprises, shorter development cycles with less ground-up engineering can equate to significant cost savings and allow more investment in innovation.

Beyond vehicles themselves, the tools, techniques and processes that are required to engineer and manufacture at scale are also benefitting from developments in the latest hardware technology. Advancements in raw material chemistry and processing, fabrication and physical sciences are leading to lighter, stronger and better-performing vehicle applications in parallel with greater connectivity.

As advancements in transportation technology continue to evolve, it’s important for companies to balance their focus on the continual development of both hardware and software technologies. Forgoing advancements in one without investing in the development of the other can lead to significant risks and missed opportunities for long-term success.

Unraveling the Mysteries of Human Tissue: A Comprehensive Atlas

Posted by in categories: biotech/medical, engineering

Which types of cells can be located in various human tissues, and where? Which genes show activity in these individual cells, and which proteins can be identified within them? Detailed answers to these inquiries and more are expected to be supplied by a specialized atlas. This atlas will particularly elucidate how different tissues take shape during embryonic development and the underlying causes of diseases.

In the process of developing this atlas, the researchers have the goal to chart not just tissues directly procured from humans but also structures referred to as organoids. These are three-dimensional tissue aggregates that are grown in the lab and develop in a manner similar to human organs, albeit on a smaller scale.

“The advantage of organoids is that we can intervene in their development and test active substances on them, which allows us to learn more about healthy tissue as well as diseases,” explains Barbara Treutlein, Professor of Quantitative Developmental Biology at the Department of Biosystems Science and Engineering at ETH Zurich in Basel.

Predicting the compressive engineering performance of carbon fibre-reinforced plastics

Posted by in categories: engineering, law

The Titan’s lack of credentials was noted in legal waivers OceanGate asked customers to sign before voyages. The company reportedly warned that its newest submersible had “not been approved or certified by any regulatory body” and that a dive “could result in physical injury, disability, emotional trauma or death.”

You do realize carbon fiber is very weak with compression. Tensile strength is superior to the compression strength. No one is talking about regulation for some reason, which disturbs me. Many things are not on the market because of regulations, like FAA regulations. However some geniuses make a sub out of carbon fiber and other cheap materials, they make people sign waivers telling occupants they are going in an unregulated craft, and people act suprised that something went wrong. Something was going to go wrong, the sub was made of carbon fiber. I don’t even know how the fibers were aligned.

This paper examines the compressive strength data of a recent experimental study [Smith FC. The effect of constituents’ properties on the mechanical performance of fibre-reinforced plastics. PhD thesis. Centre for Composite Materials, Imperial College, April 1998] concerned with the evaluation of a range of engineering properties of continuous carbon fibre/epoxy composites subjected to static tensile and compressive loading. A plastic fibre kinking analysis [Budiansky B. Micromechanics. Comput Struct 1983;16:3–12] and a linear softening cohesive zone model (CZM) [Soutis C. Compressive failure of notched carbon fibre–epoxy panels. PhD thesis. Cambridge University Engineering Department, UK, 1989; Soutis C, Fleck NA, Smith PA.

Researchers create highly conductive metallic gel for 3D printing

Posted by in categories: 3D printing, 4D printing, chemistry, engineering

Researchers have developed a metallic gel that is highly electrically conductive and can be used to print three-dimensional (3D) solid objects at room temperature. The paper, “Metallic Gels for Conductive 3D and 4D Printing,” has been published in the journal Matter.

“3D printing has revolutionized manufacturing, but we’re not aware of previous technologies that allowed you to print 3D metal objects at room in a single step,” says Michael Dickey, co-corresponding author of a paper on the work and the Camille & Henry Dreyfus Professor of Chemical and Biomolecular Engineering at North Carolina State University. “This opens the door to manufacturing a wide range of electronic components and devices.”

To create the metallic gel, the researchers start with a solution of micron-scale particles suspended in water. The researchers then add a small amount of an indium-gallium alloy that is liquid metal at room temperature. The resulting mixture is then stirred together.
