Solid-state batteries are often presented as the long-awaited breakthrough that will solve the safety problems of today’s lithium-ion batteries, promising higher energy density, faster charging, and—most appealingly—near-perfect safety. In recent years, this narrative has gained strong momentum, especially in China, where solid-state technology is frequently portrayed as a “fire-free” alternative that will eliminate thermal runaway and battery explosions altogether. However, growing voices from Chinese academia and industry warn that such absolute safety claims risk turning a promising technology into an overhyped one, creating unrealistic expectations among policymakers, manufacturers, and consumers alike. At the core of this debate lies the misconception that removing flammable liquid electrolytes automatically removes all fire and safety risks. While solid electrolytes can indeed improve thermal stability, solid-state batteries remain high-energy systems subject to complex failure m...

 When discussing the future of electric vehicles, most people immediately think of driving range. But there is another equally critical factor that shapes both performance and safety: battery lifespan. As batteries age, capacity fades, internal resistance increases, driving range drops, and safety risks begin to rise. In high-voltage lithium-ion batteries, one of the most destructive triggers behind this aging is oxygen-induced degradation at the cathode–electrolyte interface. A research team at the Ulsan National Institute of Science and Technology (UNIST) in South Korea has developed an impressive solution to this problem: a semi-solid gel electrolyte capable of “trapping” reactive oxygen species, significantly slowing down degradation. Laboratory results show that this new material can extend high-voltage battery life by up to 2.8 times and reduce cell swelling by nearly six-fold. So, how does it work? The Hidden Enemy in Lithium-Ion Batteries: Oxygen-Induced Aging To achieve hi...

If you’ve ever hesitated at an intersection, unsure whether that approaching car is actually slowing, you’ve felt the information gap this idea tries to close: a front-facing brake light, glowing green when the driver is braking. What the new research shows Researchers at Graz University of Technology (TU Graz), working with traffic-psychology experts, reconstructed 200 real intersection crashes and re-ran them with a hypothetical front brake light (FBL). The results are eye-opening: 7.5% to 17% of collisions could have been prevented, and in up to a quarter of cases, remaining crashes would have occurred at lower impact speeds—meaning less severe injuries. The peer-reviewed paper appears in Vehicles.  Why green? Multiple color options were tested conceptually, but green performed best for visual salience and psychological clarity—it’s rarely used on vehicles for other light functions and is already associated with “proceed/clear” in traffic signaling, which helps drivers parse int...

1. Introduction The European Union’s F-Gas Regulation (EU No 517/2014) is one of the most comprehensive legislative frameworks aimed at limiting the climate impact of fluorinated greenhouse gases (F-gases). This regulation targets the phasedown of HFCs (Hydrofluorocarbons)—which have high Global Warming Potential (GWP) values—while accelerating the transition to low-GWP alternatives. 2. Characteristics and Environmental Impact of F-Gases HFCs: The most widely used group of F-gases, typically applied in refrigeration, air conditioning, and heat pump systems. GWP Comparison: R134a → GWP ≈ 1430 R407C → GWP ≈ 1774 R1234yf → GWP ≈ 4 (A2L, mildly flammable) R744 (CO₂) → GWP = 1 (natural refrigerant) High-GWP gases released into the atmosphere cause a greenhouse effect thousands of times stronger than CO₂. Therefore, the EU’s strategy focuses not only on emission reduction, but also on leak prevention and the promotion of alternative technologies. 3. Core Technical Elements of the Regulation ...

In electric vehicles—especially buses and light commercial platforms—thermal management is at the core of both range and safety. The conventional approach relies on monitoring temperature, pressure, and flow while scheduling maintenance on mileage or time-based intervals. The idea of a “smart hose” turns this paradigm upside down: the hose itself becomes a sensing surface, monitoring the chemical health of the coolant flowing through it. This allows silent root causes of failure—such as leakage, ionic contamination, or acidification—to be detected before a compressor engages or insulation resistance falls below safety thresholds. With the industry rapidly shifting toward low-conductivity coolants, this approach is gaining traction. What Makes a “Smart Hose” Different? Today, pH and conductivity checks are typically done via inline probes or service equipment. Embedding miniature sensors directly into the hose material integrates this function without compromising flexibility. Academic ...

As technology continues to advance at an unprecedented pace—particularly in fields like artificial intelligence, next-generation communications, and autonomous systems—the demand for faster and more efficient computing systems has never been greater. A recent scientific breakthrough might just deliver on that need: researchers have developed a new reconfigurable system based on memristors that can sort and process data directly within memory, without relying on traditional RAM or processors. This innovation has the potential to fundamentally reshape the way computers operate. What Is a Memristor? A memristor, short for "memory resistor," is an electrical component that retains its resistance based on the history of electrical current that has passed through it. In essence, it remembers its past states, making it especially suitable for combining memory and logic functions within the same hardware. Unlike conventional computing architectures, where memory and processing are se...
