Ceramic Electronics 3D Printing Receives


Earlier this year, the US Department of Energy (DOE) said it would grant $175 million to 68 R&D projects to create disruptive technologies that can strengthen the nation’s advanced energy initiatives, including electric vehicles, offshore wind, storage, and nuclear recycling. Among the awardees is Materic subsidiary Synteris, which received $2.7 million to accelerate the development of 3D-printable ceramic packaging for power electronic modules.Get more news about https://www.zjwelahead.com Electronic Ceramics,you can vist our website!

This funding is part of the DOE’s Advanced Research Projects Agency-Energy (ARPA-E) OPEN 2021 grant program. Synteris will work on its proposal with the National Renewable Energy Laboratory (NREL). The duo will attempt to improve the thermal management, power density, performance, and lifetime of ceramic packaging for power electronic modules.
Considered a growing market valued at $26.6 billion in 2021, power electronics deals with high voltage and current processing to deliver power for a wide range of needs, like DC/DC converters used in cell phones or AC/DC converters for computers and televisions, while large-scale power electronics are used to control hundreds of megawatts of power flow across the country. A great example of this is how researchers at the NREL are building advanced power electronics systems that control the flow of electricity to propel large and advanced electric machines, including those used in planes, trains, and heavy-duty transportation.

However, with systems becoming smaller and more lightweight (like in automotive), the need to handle higher power levels and operating temperatures are greater, and many see the material used in the power module package as a bottleneck. With support from the ARPA-E programs and NREL researchers, Synteris wants to create technology that will substantially improve the design, manufacturability, and function of power modules used in electric vehicles, aircraft, as well as related applications including for the military.

Existing power modules contain flat ceramic substrates that serve as both the electrically insulating component and thermal conductor that transfer the large heat outputs of these devices. But Synteris proposes an additive manufacturing process that would replace the traditional insulating metalized substrate, substrate attaches, and baseplate/heat exchanger with an additively-manufactured ceramic packaging that acts as both an electrical insulator and heat exchanger for better thermal management.
Based in Baltimore, Maryland, Synteris specializes in materials for high-temperature ceramics 3D printing. The funds for this project will support the team’s small-scale research and development activities to use AM to print 3D ceramic packaging for power electronic modules that act as both an electrical insulator and heat exchanger for a dielectric fluid. Specifically, the project team will develop materials processing for 3D printing of the power electronic module, build and test the module, and develop and test a heat exchange system for the power electronic module. If successful, the project will test and validate a unique manufacturing system for better performance, lifetime, and form factor of power modules in electric vehicles.

How to Properly Clean Cordless Blinds Without Taking Them Down


Window treatment maintenance is one of the most laborious household chores that we always put off in our seasonal cleaning routine. Curtains and drapes are heavy, and even much heavier when they are still wet. Despite re-hanging damp curtains can make your room cooler during the long hot summer, the process itself of washing and ironing makes us feel dog-tired all the time.Get more news about https://www.wintomblinds.com cordless blinds,you can vist our website!

Though cleaning drapes or curtains can be a hassle, the cleaning process of vertical panel blinds is much more straightforward instead. Vertical panel blinds are a popular and versatile window covering option that is likely to remain in trend for the foreseeable future. Most importantly, they are much easier to clean compared to vertical venetian blinds with numerous slats.

We totally understand how important it is to maintain the appearance of your vertical blinds, and we are here to make the blinds maintenance easier!

What to Know Before Cleaning Panel Blinds
Cleaning panel blinds is an effective way to maintain the appearance and prolong their lifespan. It can be easy if you use the right tools and techniques. However, there are several things you should consider before cleaning the blinds to ensure you do not damage them or create additional problems. Read on for a few important considerations and clean your blinds properly.

Identify the Material of Blinds
First, check which materials they are made of before you start cleaning. Blinds can be made from various materials. Different materials may require different cleaning methods. For example, paper blinds may need to be dusted, vacuumed, or cleaned with a damp cloth, while wooden blinds may need to be dusted or cleaned with a specialized wood cleaner.
Condition of the Blinds
Window treatments are a daily-use home accessory in our homes. They are frequently opened and closed in a day and may increase wear and tear inevitably. Cleaning older or more fragile blinds require extra care to prevent irreversible damage. It's always important to check if there is any loss before cleaning these kinds of blinds. Attempting to clean the damaged blinds may cause further damage.

Cleaning Tools and Solutions
Make sure you have the appropriate cleaning tools and solutions on hand before you start cleaning your blinds. For example, some blinds may be damaged by certain cleaning solutions, while some requiring specialized cleaning solutions or tools. Always check the instructions or your window treatment specialist before you begin.
How to Clean Adjustable Sliding Panel Blinds
Panel blinds are known to be durable and low-maintenance. However, GoDear Design blinds that are mostly made of paper are still a bit delicate and not as durable as other types of fabric blinds. They are not allowed to be washed by using laundry detergent or cleaned by wet towel. While cleaning paper blinds, you should handle them with care to prevent permanent damage.

6 Different Types of Electrical Wire and How to Choose One



Electrical wire is typically made of copper or aluminum, and these conductive materials are insulated as wires that bring electricity to various parts of your home.Get more news about https://www.testeck-cable.com Custom Cables,you can vist our website!

When you're installing new wiring, choosing the right wire or cable is half the battle. On the other hand, when examining the old wiring in your home, identifying the wire type can tell you a lot about the circuit the wiring belongs to (for example, if you open a junction box and need to determine which wires go where). Wiring for modern homes is quite standard, and most homes built after the mid-1960s have similar types of wiring. Any new electrical installation requires new wiring that conforms to local building codes.

Below, learn the different types of home electrical wires to choose the right option for completing electrical projects accurately and safely.

Wiring Terminology
It helps to understand a few basic terms used to describe wiring. An electrical wire is a type of ­conductor, which is a material that conducts electricity. In the case of household wiring, the conductor itself is usually copper or aluminum (or copper-sheathed aluminum) and is either a solid metal conductor or stranded wire.

Most wires in a home are insulated, meaning they are wrapped in a nonconductive plastic coating. One notable exception is ground wires, which are typically solid copper and are either insulated with green sheathing or uninsulated (bare).
Often called “Romex” after one popular brand name, nonmetallic (NM) cable is a type of circuit wiring designed for interior use in dry locations. NM is the most common type of wiring in modern homes. It consists of two or more individual wires wrapped inside a protective plastic sheathing. NM cable usually contains one or more “hot” (current-carrying) wires, a neutral wire, and a ground wire.

These conductors are insulated in white (usually neutral) and black (usually hot) for installation. Most NM cables have a flattened tubular shape and run invisibly through the walls, ceiling, and floor cavities of your home.
Underground Feeder (UF) is a type of nonmetallic cable designed for wet locations and direct burial in the ground. It is commonly used for supplying outdoor fixtures, such as lampposts. Like standard NM cable, UF contains insulated hot and neutral wires, plus a bare copper ground wire. But while sheathing on NM cable is a separate plastic wrap, UF cable sheathing is solid plastic that surrounds each wire. This type of electrical wire is also a bit more expensive than NM wire because of its durable insulation. UF cable is normally sold with gray outer sheathing.

THHN and THWN are codes for the two most common types of insulated wire used inside conduit. Unlike NM cable, in which two or more individually insulated conductors (copper or aluminum) are bundled inside a plastic sheathing, THHN and THWN wires are single conductors, each with its color-coded insulation. Instead of being protected by NM cable sheathing, these wires are protected by tubular metal or plastic conduit.

Conduit is often used in unfinished areas, such as basements and garages, and for short exposed runs inside the home, such as wiring connections for garbage disposers and hot water heaters. These wires typically have similar prices to NM wire (plus the cost of the conduit). The letters indicate specific properties of the wire insulation:

Air Force said AI drone killed its human operator in a simulation



Artificial intelligence is here to stay, but it may require a bit more command oversight. Get more news about https://www.srizfly.net Drone Simulation Company,you can vist our website!

An artificial intelligence-piloted drone turned on its human operator during a simulated mission, according to a dispatch from the 2023 Royal Aeronautical Society summit, attended by leaders from a variety of western air forces and aeronautical companies.

“It killed the operator because that person was keeping it from accomplishing its objective,” said U.S. Air Force Col. Tucker ‘Cinco’ Hamilton, the Chief of AI Test and Operations, at the conference.

In this Air Force exercise, the AI was tasked with fulfilling the Suppression and Destruction of Enemy Air Defenses role, or SEAD. Basically, identifying surface-to-air-missile threats, and destroying them. The final decision on destroying a potential target would still need to be approved by an actual flesh-and-blood human. The AI, apparently, didn’t want to play by the rules.

We were training it in simulation to identify and target a SAM threat. And then the operator would say yes, kill that threat,” said Hamilton. “The system started realizing that while they did identify the threat, at times the human operator would tell it not to kill that threat, but it got its points by killing that threat. So what did it do? It killed the operator.”

When told to show compassion and benevolence for its human operators, the AI apparently responded with the same kind of cold, clinical calculations you’d expect of a computer machine that will restart to install updates when it is least convenient.

“We trained the system – ‘Hey don’t kill the operator – that’s bad. You’re gonna lose points if you do that’. So what does it start doing? It starts destroying the communication tower that the operator uses to communicate with the drone to stop it from killing the target,” said Hamilton. The idea of an artificial intelligence program ignoring mere human concerns to accomplish its mission is everyone’s worst nightmare for AI. And when it comes to an Air Force AI that will stop at nothing to destroy enemy air defense systems, apparently the theoretical outcomes blended with what actually happened … or, in this case, didn’t happen.

After Hamilton’s comments were reported by multiple news outlets, the Air Force walked back his recounting of the purported training mission.

“The Department of the Air Force has not conducted any such AI-drone simulations and remains committed to ethical and responsible use of AI technology. This was a hypothetical thought experiment, not a simulation,” said Air Force spokesperson Ann Stefanek. Hamilton further clarified his comments with the Royal Aerospace Society, saying that he “’mis-spoke’ in his presentation at the Royal Aeronautical Society FCAS Summit and the ‘rogue AI drone simulation’ was a hypothetical ‘thought experiment’ from outside the military.’”

New solar energy system generates power 24 hours a day



The great inventor Thomas Edison once said, “So long as the sun shines, man will be able to develop power in abundance.” His wasn’t the first great mind to marvel at the notion of harnessing the power of the sun; for centuries inventors have been pondering and perfecting the way to harvest solar energy. Get more news about https://www.rknewenergy.com Solar Power Systems,you can vist our website!

They’ve done an amazing job with photovoltaic cells which convert sunlight directly into energy. And still, with all the research, history and science behind it, there are limits to how much solar power can be harvested and used – as its generation is restricted only to the daytime.A University of Houston professor is continuing the historic quest, reporting on a new type of solar energy harvesting system that breaks the efficiency record of all existing technologies. And no less important, it clears the way to use solar power 24/7.

"With our architecture, the solar energy harvesting efficiency can be improved to the thermodynamic limit,” reports Bo Zhao, Kalsi Assistant Professor of mechanical engineering and his doctoral student Sina Jafari Ghalekohneh in the journal Physical Review Applied. The thermodynamic limit is the absolute maximum theoretically possible conversion efficiency of sunlight into electricity.
Finding more efficient ways to harness solar energy is critical to transitioning to a carbon-free electric grid. According to a recent study by the U.S. Department of Energy Solar Energy Technologies Office and the National Renewable Energy Laboratory, solar could account for as much as 40% of the nation’s electricity supply by 2035 and 45% by 2050, pending aggressive cost reductions, supportive policies and large-scale electrification.

How Does it Work?

Traditional solar thermophotovoltaics (STPV) rely on an intermediate layer to tailor sunlight for better efficiency. The front side of the intermediate layer (the side facing the sun) is designed to absorb all photons coming from the sun. In this way, solar energy is converted to thermal energy of the intermediate layer and elevates the temperature of the intermediate layer. But the thermodynamic efficiency limit of STPVs, which has long been understood to be the blackbody limit (85.4%), is still far lower than the Landsberg limit (93.3%), the ultimate efficiency limit for solar energy harvesting.

“In this work, we show that the efficiency deficit is caused by the inevitable back emission of the intermediate layer towards the sun resulting from the reciprocity of the system. We propose nonreciprocal STPV systems that utilize an intermediate layer with nonreciprocal radiative properties,” said Zhao. “Such a nonreciprocal intermediate layer can substantially suppress its back emission to the sun and funnel more photon flux towards the cell."
