50 Cheap Products On Amazon You’ll End Up Using Every Day

Smart shopping is like a Venn diagram: there are products that are affordable and products you’ll use all the time, and when these two categories meet, it’s a beautiful thing. And all these cheap products on Amazon? They definitely fall into that mathematically-satisfying diagram, combining affordability with practicality. This cheap and practical Venn diagram becomes very important when you’re on a budget. Even if something is cheap, you don’t necessarily want to spend your precious dollars on it if it’s just going to end up in the junk drawer. (Example: a yo-yo is cheap, but you’ll only use it twice a year, tops.) You want something you’ll use all the time, preferably every day. Luckily, Amazon is bursting at the seams with products that you’ll use constantly but won’t break the bank. You’ll find a little bit of everything on this list: products to keep your car clean and organized, clothes hangers that actually triple your closet space, a hair brush infused with natural minerals to boost shine: I could keep going, but instead, I’ll let you discover these mega-practical and super-affordable products for yourself...

Discovery of true electrochemical reactions for ultrahigh catalyst mass activity in water splitting

Better understanding of true electrochemical reaction behaviors in electrochemical energy devices has long been desired. It has been assumed so far that the reactions occur across the entire catalyst layer (CL), which is designed and fabricated uniformly with catalysts, conductors of protons and electrons, and pathways for reactants and products. By introducing a state-of-the-art characterization system, a thin, highly tunable liquid/gas diffusion layer (LGDL), and an innovative design of electrochemical proton exchange membrane electrolyzer cells (PEMECs), the electrochemical reactions on both microspatial and microtemporal scales are revealed for the first time. Surprisingly, reactions occur only on the CL adjacent to good electrical conductors. On the basis of these findings, new CL fabrications on the novel LGDLs exhibit more than 50 times higher mass activity than conventional catalyst-coated membranes in PEMECs. This discovery presents an opportunity to enhance the multiphase interfacial effects, maximizing the use of the catalysts and significantly reducing the cost of these devices. The demand for energy has increased rapidly over the past few decades as a result of worl...
