Mechanical Engineers Say Proper Ventilation is Crucial for Your Small Business


Engineers Explain How Good Ventilation Helps Your Business We’ll start with a fact that often startles people: (indoor air quality is a major health threat in the country).  According to the U.S. Environmental Protection Agency, the air quality inside buildings is often 3 to 4 times worse than the air outside. This goes against what most people think air pollution is like— fumes from cars and smoke stacks casting dark clouds over cities.  Heavy wall insulation, tightly fitted, non-opening windows ( Window Efficiency ), and commercial synthetic carpeting in modern buildings allows for the rapid build-up of contaminants inside without the chance to escape. Proper ventilation in your business that was designed by a licensed mechanical engineer(Licensed Mechanical Engineer ), is a key [...]

Mechanical Engineers Recommend Home Drainage – Winter Months are Coming !


How Do Engineers Handle Rainwater? Engineers can help with proper fitting of gutters, or eaves troughs as they are called in some parts of the country. They are an important part of the drainage system around your house.  If yours are nonexistent, in poor condition, or improperly placed on your house, they could be causing problems and putting your home at risk of water damage. Gutters need to be installed properly so that they catch the water coming off your roof and channel it away from your house and its foundation.  Your eaves troughs should have a downward slope of 1/2 inch for every 10 feet of run to ensure they drain completely.  If your house is more than [...]

Engineers Develop Ways to Ventilate Your Home


Why ventilate? For centuries homes weren’t ventilated, and they did all right, didn’t they? Why do we need to go to all this effort (and often considerable expense) to ventilate houses today?  Engineers have developed several reasons that ventilation is more important today than it was long ago. Most importantly, houses 100 years ago were leaky. Usually they didn’t have insulation in the walls, so fresh air could easily enter through all the gaps, cracks, and holes in the building envelope., the building materials used 100 years ago were mostly natural products that didn’t result in significant off gassing of volatile organic compounds (VOCs), formaldehyde, flame retardants, and other chemicals that are so prevalent in today’s building materials, furnishings, [...]

Semiconductor Industry Growth Continues


  Worldwide semiconductor revenue hit and all-time-record of $120.8B in Q2 2018, which represents an almost 4.5% quarter over quarter growth. More Integrated Circuits are being put into traditional products, such as enterprise data storage units and smart phones. Now cars, refrigerators, and a whole host of Internet of Things, are integrating chip sets into their products as well. Memory dominates chip production and usage, and has helped to keep Samsung in its leadership position. (Record Fab Spending) Samsung Remains the Number One Semiconductor Manufacturer Samsung posed Q218 revenue of $19.2B and Intel came in at $16.7B. Uncertainty at the helm of Intel with Brian Krzanich’s unexpected resignation has led to some confusion in the industry. Several semiconductor industry [...]

Engineers Who Work With Solar


(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 Looking to Future: Solar Assisted Electric Vehicles  (SAEVs)


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 [...]

Electric Vehicle Batteries: Recycled


  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 [...]

Engineering Advances: Degradation and Saving Electric Vehicle Batteries


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. [...]

NAND Flash – 11 Myths Still Floating Around


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.(  UFS memory is primarily just for smartphones. Universal Flash Storage (UFS), while smartphones [...]

Semiconductor Worldwide: Samsung Takes Over


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.
