(Figure 1. Materials Engineers) Solar energy has seen record growth in recent years, leading to greater-than-ever demand for solar engineers. In fact, according to the Solar Energy Industries Association, solar energy is one of the fastest growing sectors of the economy. According to a report released by the U.S. Bureau of Labor Statistics, “Engineers are one of the most sought-after occupations by employers in the solar power industry." The industry requires a range of types of engineers, and many of them have skill sets and training particular to working with solar. Materials Engineers Materials Engineers (See Figure 1. Above) develop, process and test materials used in the solar industry. Some of these materials include metals, plastics, glass and [...]

Material Engineers : A Pipedream? Solar-powered cars have been thought of by many as an impossible pipedream. But the innovators behind, a fully solar-powered vehicle to be released in 2019. GOING FULLY SOLAR A Car whose ability to use solar power has been thought of as an impossible feat. Designed by the Dutch startup Lightyear, the “car that charges itself” can supposedly drive for months without charging and has a 400 – 800 km range. But is a solar-powered car feasible?Up until now fully solar-powered cars were not considered a realistic prospect, Solar Assisted Electric Vehicles (SAEVs) were considered the best possible option for solar cars, adding up to hundreds of miles to a cars range. But the Dutch Lightyear promises [...]
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 doesn't emit any greenhouse gases or any other pollutants. These cars are quieter than the vehicles powered by conventional fuels, which don't cause noise pollution as well. Lets [...]
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 already risen by more than 80 per cent in 2018. Most expert Material Scientists agree that a replacement hybrid car battery can range from $1,000 to more than $6,000. The [...]
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 constantly improving to address consumer concerns. Charging an EV takes time, and unless you have fast in-home charging infrastructure or public charging infrastructure it will remain a barrier. [...]
(Figure 1 - Electric Vehicle on Fire) Electric Vehicle Battery Materials Most electric vehicle batteries are lithium based and rely on a mix of cobalt, manganese, nickel, and graphite and other primary components, can be very dangerous, battery fires could occur (See Figure 1. Above). Some of these materials are harder to find than others, though none should be classified as "rare earth metals" ( http://glewengineering.com/the-impact-of-chinese-export-restrictions-on-rare-earth-elements/) . Over 60% of the global supply for cobalt comes from the Democratic Republic of Congo (DRC), which has a poor human rights track record; international organizations have denounced for years the exploitative labor practices involved in cobalt production. Cobalt deposits can be found throughout the world and are most prominent in the African Copper [...]
Good News for Materials Scientists - Semiconductor Record Spending Fab spending reports show unprecedented high semiconductor equipment sales are being driven by a handful of well-known companies, and also by several new Chinese companies entering the semiconductor marketplace. An increase in overall fab spending (greenfield construction and equipment together) of 54 percent year-over-year (YoY) in China is expected. Total spending in China rose from $3.5 billion in 2016, to $5.4 billion in 2017, and then is anticipated to be $8.6 billion in 2018, another 60 percent year-over-year (YoY). The demand for Materials Scientists to develop manufacturing processes and engineers to install and maintain the equipment will be huge as well . Fab Spending is Beyond Silicon Valley China-based companies [...]
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 (<32 Gb), while high-density NAND flash (≥64 Gb) is typically used in the toggle-mode interface.( http://glewengineering.com/tester-prober-interfaces-direct-probe-part-1/ UFS memory is primarily just for smartphones. Universal Flash Storage (UFS), while smartphones [...]

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 to 2017, and NAND flash prices went up 17 per cent year-over-year for the first time. (See Figure Below) A Gartner table provides the numeric nitty-gritty [...]
A Licensed Mechanical Engineer at Glew Engineering Consulting was asked by a company in Southern California to provide a Professional Engineer (P.E.) review of body modifications that they made to a theme park owned 1983 Sport Utility Vehicle (SUV) that they had converted to an electric vehicle. Figure 1. A Mechanical Engineer Analyzed the Front of Custom Sport Utility Vehicle Licensed Mechanical Engineer Reviews a Modified Electric Vehicle The client had already designed and built a vehicle, so Glew Engineering analyzed an “as built” vehicle. The company hoped to repurpose a float/SUV that they had used previously in parades. Our client was requested by the theme park to repurpose the SUV, and perform cosmetic alterations [...]

Liquid crystal display (LCD) screens are omnipresent in our technologically saturated lives. Having largely displaced the older CRT screens, LCDs make up a large portion of the digital imaging we see all around us. They are present in everything from our ubiquitous smartphones and computer screens to digital billboards, wristwatches and vehicle and aircraft instrumentation. How do flat panel LCD screens work? One can often find videos and articles documenting eager teardowns of new devices, but few delve beyond the hardware and into the materials and design behind the screen itself. For this series of blog posts, we will be review some aspects of display technology , why they work, and how they are assembled. To illustrate my points, I’ve disassembled a legacy Sony Ericsson® S500i phone [...]
