Composite Brush 1.3 PORTABLE



In this context, numerous efforts have been devoted to addressing these issues and unlocking the full potential of Li metal anodes. One method is to optimize the liquid electrolytes by adjusting the electrolyte compositions19 or adding various electrolyte additives20,21,22,23. These additives can react rapidly with Li metal to modify the chemical composition of SEI layers and thus improve their stability and uniformity. Nevertheless, in most cases, the in situ formed protecting layers are still not strong enough to withstand the mechanical deformation induced by dendrite growth, and stable cycling is not sustainable over a long period of time due to the consumption of such additives24,25. Another method is to ex situ coat the surfaces of Li metal anodes by various artificial protective layers, such as polymeric grafted skin26, ultrathin Al2O3 layer27, and LiF/PVDF-HFP composite film28, which offer high chemical stability and mechanical strength, thus overcoming the fragility issue. However, the artificial protective layers often result in increased polarization voltages because of their relatively high resistance28. Additionally, ex situ coating procedures are usually tedious and dangerous because of the highly reactive nature of Li metal, which could make large-scale industrial operations difficult.

Uniform and stable Li deposition is regulated by employing 2D molecular brush-functionalized porous bilayer composite separators, which are facilely obtained by coating the GO-g-PAM molecular brushes on commercial PP separators with an upscalable blade-coating procedure. Benefiting from the abundant polar functional groups of hairy PAM chains, the interconnected interspaces between the stacked 2D molecular brushes, and the robust mechanical strength of GO nanosheets, the functional porous bilayer composite separators not only possess excellent mechanical strength but also facilitate molecular-level homogeneous and fast Li ionic flux on the surfaces of electrodes. These unique features of the functional porous bilayer composite separators enable dendrite-free uniform Li deposition with high Coulombic efficiency at Li metal anodes as well as ultralong-term reversible Li plating/stripping at ultrahigh current densities.


If a tool in Photoshop isn't working properly (for example, the crop tool crops a tiny little gray square, or painting with a brush paints the wrong color or nothing at all), try resetting the tool settings:

Prod #DescriptionUnitPriceOrder / Quote54529Precision Scratch Brush Seteach$45.10Qty: Anti-Static Brushes Static electrical charge is generated between materials through friction, pressure or separation of two materials. This is sometimes called the Triboelectric Effect. A material that inhibits the generation of static charges (generally less than 200 volts) from triboelectric generation is classified as anti-static. Anti-static materials used to make brushes include Wood, Hog Bristle, Horse Hair and Goat Hair. These materials can be used in ESD sensitive areas as long as the brush remains in a liquid environment. In a dry environment only conductive or dissipative materials should be used in ESD safe areas. The most critical aspects of the ESD brush are the fiber, core or handle material, and grounding. Surface resistivity of the brush material largely determines the electrostatic properties of the brush. Range of surface resistivity (ohms) is: 1012 to 1016 Insulative materials 105 to 1011 Dissipative materials 102 to 104 Conductive materials Anti-Static brushes are made from low charging and natural materials that are near neutral on the triboelectric chart. They neither give nor take electrons and, therefore, remain essentially electrically neutral. There can, however, be a slight charge created. In extreme voltage sensitive applications, these brushes should be used only in a liquid environment.


If the mounting location is not grounded, a grounding strap or wire incorporating a 1 megohm resistor should be used between the brush and an electrical ground. Potentially severe bodily harm may result from the use of a conductive brush if a 1 megohm resistor is not used. Note: Conductive fibers are NOT recommended for use with unencapsulated electronic microcircuits. Minute pieces of conductive material have been known to cause short circuits.


These dissipative brushes have a surface resistivity of 105 to 1011 ohms, a higher resistivity than the conductive brushes but sufficiently conductive to preclude any static buildup in the brush. These are excellent tools to use in removing any static charge that will result in the adhesion of particles such as dust to an object. Please use these brushes with a wrist strap or other mechanism to provide a path to ground for safety. Thunderon™ is a very fine (0.04mm, 0.0015"diameter) acrylic fiber chemically bonded with copper sulfide. This special fiber will dissipate a charge on an electrically charged surface. The surface resistivity of Thunderon™ is 102 ohms. The plastic handle is dissipative with a surface resistivity of 105 Ohms.


Bristles are made of conductive nylon fibers that remove static as they clean. Because it won't scratch critical surfaces, it's ideal for cleaning film, slides, optics, cuvettes, balance pans, microscopes, electronics and computer monitors. It has a conductive composite handle.

At first, years ago, it was just an occasional piece of plastic trash that Kahi Pacarro, the founder of Sustainable Coastlines Hawaii, picked up on the beach cleanups he organized around the state. A straw here, a takeout container there. But one day Pacarro spotted something particularly surprising in the beach detritus: a toothbrush.


Now, some designers are looking for ways to reimagine this crucial, classic object in a way that puts less stress on the planet. But to find solutions to the toothbrush conundrum, we have to understand how we got here.


Tooth care even occupied the mind of the reigning Chinese emperor Hongzhi in the late 1400s, who designed something that looked a lot like the brush we know today. It featured a short, dense pack of boar bristles, shaved off the neck of a hog, set into a bone or wood handle.


The few dentists serving the Union Army despaired at the state of the teeth around them, but dental care failed to take hold as a priority for the North. The Confederate Army, in contrast, conscripted a cadre of dentists who stressed preventative care; one army dentist pushed the message so successfully that soldiers in his unit shoved their toothbrushes in their buttonholes, readily available at all times.
