🚨 A MAJOR BARRIER TO TURNING CO₂ INTO USEFUL FUEL MAY HAVE JUST FALLEN. Scientists have developed a new catalyst that triples methanol production while solving a decades-old chemistry trade-off. For years, researchers trying to turn carbon dioxide into methanol (a valuable fuel and chemical feedstock) have faced an annoying trade-off: at lower temperatures the reaction is more efficient, but CO₂ is hard to activate. Raise the temperature to speed things up, and you get more unwanted carbon monoxide instead of methanol. A team at the Dalian Institute of Chemical Physics has now broken this deadlock. By redesigning the catalyst so that different reaction steps happen on spatially separated active sites, they achieved a space-time yield of 1.2 g of methanol per gram of catalyst per hour roughly three times higher than standard commercial Cu/Zn/Al catalysts. Why this matters: • Methanol from CO₂ is seen as a key route for carbon recycling and producing sustainable fuels and chemicals • The new design dramatically improves both activity and selectivity at the same time • It reduces the formation of carbon monoxide byproduct while keeping hydrogen dissociation efficient • This kind of catalyst improvement is essential if we want CO₂-to-fuel processes to become economically viable at scale The deeper implication: Converting CO₂ into useful products has always been limited by fundamental chemistry trade-offs. By cleverly separating reaction steps across different parts of the catalyst, this work shows we can overcome those limitations without needing extreme conditions or exotic materials. It’s a practical step toward making carbon capture and utilization more efficient turning one of our biggest waste products into something valuable instead of just burying it. We’re getting closer to catalysts that don’t force us to choose between speed and cleanliness. How important do you think breakthroughs like this will be for scaling up carbon-to-fuel technologies in the coming years?

If you have lagging Arms and bringing them up to par is your TOP PRIORITY… I’d recommend doing something like this each week: Upper A • 2-3 sets of “The GREATEST Triceps exercise known to man” • 2-3 sets of Supinated Grip Curls w/ Upper Arm Support • 2-3 sets of Machine or Cable Overhead Extensions • 2-3 sets of Hammer Grip Curls w/ Upper Arm Support Upper B (Performed 3-4 days after Upper A) • 2-3 sets of Dip Machine • 2-3 sets of Machine or Cable Preacher Curls • 2-3 sets of “The GREATEST Triceps exercise known to man” OR Machine or Cable Overhead Extensions • 2-3 sets of Hammer Grip Curls w/ Upper Arm Support This will result in you doing somewhere between 8-12 sets of direct Bicep and Tricep work per week Low likelihood you need any more volume than that to improve your Arms mightily if following the notes below: 1) The ideal rep range to be using when performing the exercises mentioned is the 5ish to 10ish rep range — Choose a weight you can do for 5, 6, 7 reps @ 0-2 RIR…once you can do that weight for 8, 9, 10ish reps, increase the load by 5ish pounds 2) You should perform all reps of all the listed exercises with a controlled (but not overly slow) eccentric and an explosive (but still controlled) concentric 3) You should perform these exercises very early in your workout to ensure they are as efficient/effective as possible — If you perform them later on, you will not get as robust a growth stimulus from the sets because of the outstanding fatigue that will be present from the earlier sets/exercises in your workout Additional notes: - You may sub any of these exercises for comparable exercises due to preferences and/or equipment availability — Ex: Dip Machine subbed for Weighted Dips - I probably forgot something that I should’ve mentioned…if I think of it I’ll drop it in the post below
