Researchers at Seoul National University have developed a new class of ultralight structural materials that combine the load-bearing strength of engineering materials with the weight of foam. Using a method called 3D node winding, the team created mesoscale carbon fiber lattices that achieve aluminum-level performance on a strength-to-weight basis while weighing as little as 1/100 the weight of aluminum. The findings, published in Nature Communications, demonstrate a new way to build strong, lightweight structures without the need for joints or layered assembly. https://techxplore.com/news/2026-04-ultralight-carbon-fiber-lattices-aluminum.html Engineering Wed, 29 Apr 2026 16:40:01 EDT news696699182 Diamond coatings are considered a key technology for numerous industrial applications—from power electronics to optics to sensors. To enable these high-performance coatings to fully realize their potential, uniformity is crucial. Researchers at the Fraunhofer Institute for Surface Engineering and Thin Films IST have developed a new measurement and analysis method that allows the optical constants of large-scale diamond films to be determined with high precision and efficiency. https://techxplore.com/news/2026-04-precise-method-diamond-coatings.html Engineering Wed, 29 Apr 2026 16:00:02 EDT news696695761 There is no question that violin-making is an art form. It requires a musician's ear, a craftsperson's skill, and a historian's appreciation of lessons learned over time. Making a violin also takes trust: Violin makers (luthiers) often must wait until the instrument is finished before they can hear how all their hard work will sound. But a new tool developed by MIT engineers could help luthiers play around with a violin's design and tweak its sound even before a single part is carved. https://techxplore.com/news/2026-04-virtual-violin-realistic-wood.html Engineering Wed, 29 Apr 2026 14:40:08 EDT news696691981 Nature is replete with slender filaments that bend and coil—from climbing grape vines, to folded proteins, to elephant trunks that can pick up a peanut but also take down a tree. https://techxplore.com/news/2026-04-programmable-3d-filaments-mimic-artificial.html Engineering Wed, 29 Apr 2026 14:20:08 EDT news696690961 If a city's suburban railway network is expanded, additional flats are likely to be built in an agglomeration that is better connected as a result. The opposite also holds true: If new buildings spring up like mushrooms in a suburb, this will call for an expansion of the transport infrastructure. Urban development and transport therefore have a mutual relationship. https://techxplore.com/news/2026-04-traffic-roads.html Engineering Wed, 29 Apr 2026 12:40:05 EDT news696684721 Until now, fine particulate matter generated by tire and brake wear has not been addressed in European emissions legislation. Only with the introduction of the Euro 7 standard—taking effect at the end of 2026 for newly developed (type-approved) vehicles and at the end of 2027 for all newly registered passenger cars and light commercial vehicles—will binding limit values be introduced. The goal is to restrict the emission of fine particulate matter with diameters less than 10 micrometers, particles that can penetrate deep into the respiratory tract. A project consortium involving Fraunhofer IWU now presents a stainless-steel brake disk that easily meets the strict EU requirements. https://techxplore.com/news/2026-04-stainless-steel-disks-significantly-fine.html Engineering Wed, 29 Apr 2026 11:00:13 EDT news696678744 Understanding how people use the spaces they inhabit—where they live, work, and gather—is key to effective urban planning that meets their needs. For example, knowing which routes are most commonly used to travel from residential neighborhoods to workplaces, and during which time periods, makes it possible to adjust bus routes and frequencies, and to optimize traffic control resources. Identifying meeting, leisure, and event spaces, as well as the time periods when crowds are largest, is useful not only for keeping the public informed, but also for strengthening cleaning and transportation services and developing promotional strategies. The more accurate this information is, the more it will help public administrations to plan urban space and services in effective and realistic ways. https://techxplore.com/news/2026-04-cell-based-reshape-city-bus.html Engineering Tue, 28 Apr 2026 17:40:07 EDT news696615841 Imagine a display that harvests ambient light when it is not actively in use, offsetting some of its own energy consumption. Materials physics shows that this is possible; the same semiconductor material can, in principle, emit and absorb light efficiently. What has been missing is a device architecture that allows it to do both without reductions in efficiency of either application. A new study reports a perovskite diode that converts sunlight to electricity at 26.7% efficiency (a world record at the time of publication) and emits light at 31% efficiency, figures that would be high for a device designed to do only one of those things. The work is published in the journal Joule. https://techxplore.com/news/2026-04-solar-cell-moonlights-absorbing-emitting.html Engineering Tue, 28 Apr 2026 16:40:04 EDT news696612362 To reliably complete various manual tasks, robots should be able to handle a variety of objects, ranging from items found in households to tools used in specific professional settings.

These hole structures, commonly used for bolts and fasteners in rotating parts, create stress concentration sites that are prone to cracks and failure under repeated stresses of high-temperature operation. https://techxplore.com/news/2026-04-hot-longer-rotating-expansion-superalloy.html Engineering Tue, 28 Apr 2026 13:20:02 EDT news696597940 Workplace hearing loss is one of the most common work-related illnesses. While hearing loss is preventable with earplugs, they can be uncomfortable, and users often remove them despite the risks. Low-frequency sounds, such as rumbling traffic and warehouse vibrations, are especially difficult to address because differences in ear physiology allow sound to leak into ears, despite protection from earplugs. https://techxplore.com/news/2026-04-meta-earplugs-booming-voice-effect.html Consumer & Gadgets Tue, 28 Apr 2026 11:00:19 EDT news696500461 Researchers have developed an ultra-thin optical film that improves the quality of the light used in LCD resin-based 3D printers.
