Engineeringness

Excited to share that our latest Engineeringness video is now live! This one is all about Bernoulli’s Principle — one of the most important ideas in fluid mechanics, but also one of the most commonly oversimplified. In the video, we break down: - What Bernoulli’s equation actually means - Why “faster fluid = lower pressure” is not the full story - How pressure, velocity, and elevation are connected - Where Bernoulli’s principle is used in real engineering systems - And where the equation starts to break down This is also the first video in a new fluid mechanics series we’re launching on Engineeringness, which will run alongside our existing engineering principles and electronics content. We’re really excited to start expanding into more core engineering topics, and we’d love to hear your feedback. Please check it out, let us know what you think, and tell us if there’s anything we can improve for future videos. https://lnkd.in/e_WJpEMb #Engineering #FluidMechanics #Bernoulli #EngineeringEducation #STEM #MechanicalEngineering #ChemicalEngineering

Everything You Need to Know About BJTs | How Bipolar Transistors Really Work Bipolar Junction Transistors are fundamental to modern electronics, but many explanations stop at the simplified idea that they are merely current-controlled devices. In reality, the physics is more interesting than that. This video takes a deeper look at how BJTs really operate, from charge carrier injection and the role of the thin base region, through to the relationship between base–emitter voltage and collector current, and finally to practical operation in switching and amplification circuits. Topics covered include: • BJT structure and polarity • transistor action at the semiconductor level • why collector current is fundamentally linked to base–emitter voltage • cut-off, active mode, and saturation • switching behaviour and practical circuit operation The aim was to make this both technically accurate and accessible, so that students, engineers, and curious learners can build a stronger intuition for one of the most important devices in electronics.

🔬 New Guidelines Aim to Improve Imaging of Next-Generation Battery Materials 🔋 The research was led by Professor Shirley Meng the University of Chicago Pritzker School of Molecular Engineering has identified key challenges in the way scientists image battery materials using transmission electron microscopy (TEM). The study,, brings together researchers from the Energy Storage Research Alliance (ESRA), Argonne National Laboratory, the University of Chicago, and Thermo Fisher Scientific to examine how imaging techniques can unintentionally alter highly reactive battery materials such as lithium and sodium metals. One of the key findings challenges a long-standing assumption in battery research. The team demonstrated that pure lithium metal can be imaged at room temperature when transferred in an inert gas environment, rather than requiring cryogenic conditions as previously believed. The researchers also found that variations in electron beam intensity can alter the structure of materials such as lithium fluoride, potentially leading to inconsistent results across laboratories. To address this, the team proposed a set of standardized guidelines for handling, transferring, and imaging reactive battery materials. These recommendations aim to improve reproducibility across research groups and ensure that experimental results more accurately reflect the true structure of battery materials. 📖 Read the full article here: https://lnkd.in/ehrqa8Cw 🔬 Key Takeaways: ✅ Electron microscopy can unintentionally alter lithium and sodium battery samples ✅ Inert gas transfer allows high-resolution imaging of lithium at room temperature ✅ Standardized imaging guidelines could improve consistency in battery research As battery technologies continue to evolve, accurate material characterization will become increasingly important for electric vehicles, grid storage, and next-generation energy systems.

🌊 Standardizing Wave Energy Converter Design Could Accelerate Ocean Renewable Power ⚡ A research team led by Assistant Professor Maha Haji at the University of Michigan College of Engineering has developed a standardized prototyping framework for wave energy converters, helping address one of the major barriers slowing development of ocean based renewable power. Wave energy has long been recognized as a promising renewable resource. Ocean waves are consistent, predictable, and significantly more power dense than wind, yet the field has struggled to progress due to fragmented design practices and inconsistent experimental methods. The researchers developed two prototype systems. One is a heaving point absorber, which moves vertically with waves, while the other is an oscillating surge converter, which rotates as waves push against it. Both devices were designed using a unified engineering framework that incorporates fluid scaling, resonance tuning, mooring design, and power take off optimization. By consolidating previously scattered design knowledge into an open methodology, the work provides a practical engineering roadmap for future laboratory studies and could help accelerate progress toward commercial wave energy systems. 📖 Read the full article here: https://lnkd.in/euHc5ckY ✅ First standardized design methodology for small scale wave energy converter prototypes ✅ Improves experimental consistency across wave energy laboratories ✅ Helps researchers focus on innovation rather than repeating early stage design mistakes What role do you think wave energy could play in the global renewable energy mix over the next decade?

⚡ EV Battery Innovation May Outpace Climate-Driven Degradation 🔋 New research from the University of Michigan, led by Haochi Wu, suggests that improvements in electric vehicle battery technology are advancing quickly enough to offset degradation caused by rising global temperatures. Researchers compared batteries produced between 2010–2018 with newer systems manufactured between 2019–2023. The results show that while older batteries could experience lifetime reductions of up to 30% under a 2°C warming scenario, newer batteries would see much smaller impacts, with degradation limited to about 10% in the most extreme cases. These findings highlight how ongoing improvements in battery materials, thermal management, and battery management systems are strengthening the durability of electric vehicles, even as global temperatures rise. For engineers and policymakers working on the electrification of transportation, the research provides evidence that technological innovation may help maintain battery reliability in a warming climate. 📖 Read the full article here: https://lnkd.in/eMChWzFZ ✅ New EV batteries show significantly lower degradation in warmer climates ✅ Technological advances are progressing faster than climate-driven damage ✅ Battery improvements strengthen confidence in long-term EV adoption What are your thoughts on the future of EV battery durability in a warming climate?
