A novel imaging technique that uses a synthesized form of scorpion venom to light up brain tumors, has shown promise in a clinical trial.
A self-contained system called ULiSSES™ , winner of Tech Briefs Media Group's this year. Extends the life of organs to 24 hours, circulating oxygen instead of calling for the ice.
Rose inspired device, inexpensively collects and purifies water. The device, a new approach to solar steaming for water production.
Wearable Brain Machine Combining new classes of nanomembrane electrodes with flexible electronics and a deep learning algorithm could help disabled people wirelessly control an electric wheelchair. Interacting with a computer, or operate a small robotic vehicle without donning a bulky hair-electrode cap or contending with wires. This work reports fundamental strategies to design an ergonomic, portable EEG system for a broad range of assistive devices, smart home systems, and neuro-gaming interfaces. Not to mention, primary innovation is in the development of a fully integrated package of high-resolution EEG monitoring systems and circuits [...]
Figure 1. Self Sufficient Home with Combined Heat and Power Combined Heat and Power (CHP) Engineers combined heat and power (CHP) systems, also known as cogeneration, generate electricity and useful thermal energy in a single, integrated system. CHP is not a technology, but an approach to applying technologies. Heat that is normally wasted in conventional power generation is recovered as useful energy, which avoids the losses that would otherwise be incurred from separate generation of heat and power. While the conventional method of producing usable heat and power separately has [...]
Figure 1. Solar Powered Cars in the Future Although a solar power car may not be commercially viable right now, there are ways that solar power can be added to existing designs to make vehicles more efficient. Material Scientist examine the pros and cons of this technology, it can continue to move forward in development to help save on fossil fuels, and the electric grid and pollutions. Solar-powered vehicles (Solar Cells ) have zero emission level, as they don’t utilize non-renewable resources and burn fuel. The electric motors generate electricity (See Figure 1.) that [...]
Material Scientist Ponder What to Do With Used EV Batteries As electric vehicles become mainstream, mechanical engineers and chemical engineers are trying to address the big environmental question: what do we do with the used lithium-ion batteries? The batteries used in electric cars are physically large, last 8 to 10 years, and will account for 90 per cent of the lithium-ion battery market by 2025. This will increase lithium demand fourfold, and more than double the demand for cobalt — two of their essential elements. The price of cobalt has [...]
Degradation of EV Lithium Batteries Battery degradation in Electric Vehicles (See Figure 1. to Right) leads to capacity fade, thereby shortening the vehicle’s possible range. Patterns are beginning to emerge and provide valuable insight into EV battery capacity and lifetime. Most drivers are retaining over 90% of original capacity Range Anxiety Some cars have a range of only 106 miles, equivalent to just over three times the average daily drive in the US. New Electric Vehicles are expected to have a range of up to 235 miles, a 220% increase, therefore, range is [...]
Think You Know NAND Flash? NAND flash has become the de facto memory standard in the years since Toshiba first introduced it almost three decades ago. However, many misconceptions remain to this day about its use. A wide variety of NAND flash-memory products are available, all with significantly different features and capabilities. All NAND flash has the same interface. NAND flash, introduced by Toshiba more than 20 years ago, is available in both the asynchronous and toggle-mode interfaces. The original asynchronous interface is found mostly in lower-density devices [...]
Samsung topples Intel as top dog semiconductor market share Gartner beancounters say price rises driven by memory shortages propelled Samsung into the lead based on semiconductor vendor revenue, vaulting past Intel and its CPUs. The largest memory supplier, Samsung Electronics, gained the most semiconductor market share and took the No. 1 position from Intel – the first time Intel has been toppled since 1992. Memory accounted for more than two-thirds of all semiconductor revenue growth in 2017, and became the largest semiconductor category. DRAM prices rose 44 per cent from 2016 [...]
Fig. 1 A street bike shown in CAD mesh. Mechanical Engineering Consulting Group Evaluates 3D CAD Programs Mechanical Engineering Consulting Testing of Creo™, Solidworks™, and Inventor™ Mechanical Engineering Consulting service companies largely use one of three 3D CAD programs: Creo™, Solidworks™, and Inventor™. At Glew Engineering, we have licensed seats of all three CAD mechanical design packages. We reviewed the CAD workflow and feature sets of each 3D CAD program using motorcycle frame design as an example. Also, we showed that some of the specialized commands of each 3D CAD software programs [...]
As energy efficient environmentally conscious engineers, we here at Glew Engineering do what we can to save energy and resources both around home and around the office. This might mean choosing products that are more environmentally friendly or energy efficient. It might mean using our surroundings to our advantage, like pulling cold air through a home or office at night so the building needs less air conditioning the next day. The most satisfying thing, though, is to employ our knowledge of mechanical engineering, materials science and thermal management to design custom hand-tooled [...]
Figure 1: Mars Exploration Rover By NASA/JPL/Cornell University, Maas Digital LLC [Public domain], via Wikimedia Commons Depending on which Facebook pages or Twitter feeds you follow, some of you may have caught wind that Opportunity (Mars Exploration Rover B, Figure 1) recently passed its twelfth anniversary of its landing on the red planet. Opportunity’s ongoing trek across Mars represents a fantastic accomplishment in engineering. At the time I’m writing this, the rover has been in continual operation for over 4,300 Earth days (that’s about 4,185 Sols, or [...]
