Here’s what reviewers are saying:
“Like to keep your beer cold? Get this. Slow drinker but don’t want to let your friends on to how slow you’re drinking? Get this. Want your White Claw/Truly to stay as cold as it was when you took it out of your fridge? Get this. I kid you not this thing keeps drinks cold like that’s its job (because it is). Once I got mine and saw how effective it was, I decided all of my cold beverage loving friends and family will be getting one also.”
“If you like to drink the slim cans, you totally need to pick up one (or two or three!) of these. This was my first BrüMate item, so I was very surprised at how durable it was and heavy (in a good way, not heavy in a bad way). It was SO effective here in Florida since it’s still hot here even in winter.”
“Perfect for tall slim beer cans! So I have tried to find the perfect beer coozie for a Michelob Ultra, Bud Lite Lime & Corona Premier tall slim can. This is the perfect fit!!!! The top unscrews & you slip your can in & then twist the top back into place to tighten. I also love how the both sides have a slight flat surface so you can hold the coozie easy with no slippage at all!”
“I bought the Hopsulator Slim in grey so me and my husband could share. We got it on Sunday and we’re already fighting over it! It fits our energy drinks for the morning and slim can beers at night! (And don’t say- no beer should have to stay cold that long, we have 3 kids and it keeps it ready for me through all 3 ‘bedtimes’ plus second attempt bedtimes).”

Scrap Copper processing Metal-Organic Frameworks (MOFs) have shown great potential in catalysis due to their high surface area, tunable pore size, and diverse chemical functionality. In this study, we present the preparation of a novel MOF, (Cu-N-COF), consisting of atomically dispersed copper sites coordinated to nitrogen and carbon atoms in a two-dimensional imine linked framework. These highly dispersed copper sites facilitated the efficient reduction of nitrogen dioxide (NO2) to nitrogen monoxide (NO) in the presence of hydrogen (H2) at room temperature and atmospheric pressure. X-ray photoelectron spectroscopy (XPS) confirmed the successful incorporation of copper into the framework. Transmission electron microscopy (TEM) indicated that the Cu-N-COF framework was composed of interconnected two-dimensional sheets with well-defined pores, and the copper sites were homogeneously dispersed throughout the framework. Catalytic tests were performed under different reaction conditions to investigate the effect of temperature, pressure, and reaction time on the catalytic activity. Remarkably, Cu-N-COF showed high catalytic activity and selectivity toward the reduction of NO2 to NO, with a conversion rate of 100% and a selectivity of 95% under optimal conditions. The turnover frequency (TOF) of Cu-N-COF was nearly eight times higher than that of Cu dispersed on activated carbon and 2.3 times higher than that of CuO nanoparticles supported on aluminum oxide. The outstanding catalytic performance of Cu-N-COF could be attributed to the high dispersion of copper sites and the synergistic interaction between nitrogen, carbon, and copper atoms in the framework. Density functional theory (DFT) calculations suggested that the active intermediates were coordinated to the copper sites and could be easily reduced by H2 assimilated on the nitrogen atoms in the framework. In conclusion, we have successfully synthesized a novel MOF with highly dispersed copper sites for efficient reduction of NO2 to NO. This work provides a new strategy for designing highly efficient and selective catalysts based on atomically dispersed metal sites in MOFs Metal waste trade Copper scrap legal considerations Copper scrap processing innovations Copper tube bar scrap acquisition Copper scrap material recovery Scrap metal purchasing
