Scientists Used Carrots and Beets To Make CrazyStrong Concrete

first_imgEver walk through the produce section of your local grocery store and think “man, I bet that would make a great concrete additive”? I’m guessing no, but on the off chance you did you may have been right.It would have depended on which particular vegetable you were talking about. Thanks to the work of scientists at Lancaster University in England, we now know that carrots and beets can be used to make super-strong concrete.There’s more to it than just popping a bit of veg into a food processor and pulsing it into shreds, naturally. The research team created sheets of “nanoplatelets” which they created out of cellulose extracted from the carrots and beet roots.Those “nanosheets” were added to a run-of-the-mill concrete mix with amazing results. Producing one cubic meter of concrete normally requires about nine 50kg bags of cement. Adding the nanosheets let the research team cut out almost an entire bag without sacrificing strength or quality.The Lancashire U team had a bit of help from Scotland-based CelluComp, a company that “develop[s] microfibrillated cellulose based on waste streams of root vegetables.” They market the cellulose they produce as Curran, and it’s already being used in products ranging from paint and ink to drilling fluids.On the scale of a single cubic meter that might not be such a big deal. But when humans are churning out around 10 billion tons of concrete every year it’s crystal clear just how big an impact this could have on our planet.Cement production is a very energy-intensive process and a major source of CO2 emissions. On average, 9kg of carbon dioxide are produced for every 10kg of portland cement. Reducing cement use by 10% or so would be a massive environmental win — and these beet and carrot nanosheets could make that possible.They could also lead to enormous savings on repairs. The research team also found that the nanosheets can also be applied to existing structures to provide a boost in strength and durability.Let us know what you like about Geek by taking our survey.last_img read more

Devil May Cry 5 Is Devilishly Delightful

first_img Titles like Resident Evil 7 and Mega Man 11 prove Capcom knows how to successfully resurrect its beloved franchises. The famed Japanese publisher/developer is restoring another classic with Devil May Cry 5. Like those aforementioned titles, Devil May Cry 5 has everything that made the series great while introducing fresh gameplay elements. The end result is one of the best games in the Hack-n-Slash franchise.Devil May Cry 5 takes place several years after the events of Devil May Cry 4. A new demonic threat emerges and it is up to devil hunters Dante and Nero to stop it. I won’t go into story specifics, but Devil May Cry 5 tells an entertaining tale that’s relatively easy to follow. Though it is the fifth installment, you don’t need to have played any of the previous games. Even if you don’t watch the DMC story recap video, you’ll understand the narrative just fine.The big draw of Devil May Cry 5 is being able to play as three distinct characters. Nero, Dante, and newcomer, V, each have unique gameplay styles. Most of the time, you’re locked into playing as a specific character. Other times, you’re free to choose who to play as. Going with three playable characters was a smart decision since it prevents the game from becoming overly repetitive.Nero seems like the “vanilla” character since he only carries two weapons (a sword and gun). However, the character uses disposable robotic arms that lends him a wide array of attacks. Devil Breakers let Nero do things like stun, electrify, or blast foes. One arm has the ability to slow down time while another can remotely attack enemies from a distance. Devil Breakers eventually run out, but there are plenty scattered throughout levels or available from the item shop. Also, Nero can use his arm to pull enemies closer to him, which is always useful.Dante is what I call the swiss army knife character. The infamous devil hunter has four different styles: Swordmaster, Trickster, Royal Guard, and Gunsmith. On top of that, he has a wide range of different melee weapons, long-range weapons, and different Devil Triggers. Since one can mix and match all of Dante’s different attacks, he is a complex character to use. However, he is also the most rewarding to master. Dante is the legendary devil hunter through and through.Then there’s V. Unlike Dante and Nero, V is not a close-range fighter. Instead, the character uses a demonic bird, panther, and golem to attack. This forces players to employ a completely different playstyle since they have to attack from afar. I honestly wasn’t a fan of V at first, but his quirky gameplay style eventually won me over. I still prefer the two white-haired heroes, but playing as V is more enjoyable than it is frustrating.As you explore levels and kill demons, you’ll gather red orbs. This is your main currency for unlocking new skills, buying items, and upgrading weapons. Given their abundance, you’ll have more than enough orbs to constantly upgrade each of the characters. In addition to red orbs, you can find blue shards to increase your health, white shards to increase the devil trigger, and yellow stars that resurrect you upon death. Searching the world for these objects is half the fun of playing DMC5 since some items are in hard-to-reach areas.Though a single player game, Devil May Cry 5 has a form of multiplayer. During certain levels, you’ll actually see a player-controlled character in the background. They may even join you directly in battles. You can rate these players after completing a level. While this is an interesting feature, it doesn’t add much to the actual game. During my time, the other player was usually somewhere beyond reach. In all honesty, it would have been better to have full-blown co-op instead of this. But since it doesn’t impact the overall game, I can’t complain too much.This is the smoothest-playing Devil May Cry title ever released. Though combat is challenging, transitioning between different attacks is easy and seamless. This allows users to create their own unique combos. This is great considering how the game rewards players for being stylish. Though some platforming segments feel awkward, combat never fails to deliver. DMC5 sets a new standard for Hack-n-Slash controls.The Devil May Cry games have always had impressive graphics but Devil May Cry 5 takes the visuals to another level. This is due to the game running on Capcom’s RE Engine, which also powers Resident Evil 7 and Resident Evil 2. All of the environments: from devastated city streets to hellish underworlds, come to life in stunning detail. More often than not, Devil May Cry 5 looks like a special effects-driven Hollywood blockbuster. Everything, no matter how (literally) out-of-this-world, looks absolutely realistic.Visually, I liked the various environments in Devil May Cry 5. Unfortunately, they aren’t as imaginative as those of previous installments. While there are some truly creative levels, most are rather mundane. This is especially true of the latter half where levels not only look the same, but are fairly straightforward. I’m obviously trying to be as vague as possible here, but I felt disappointed by the level designs in the last half of the game.Devil May Cry games are notorious for their high difficulty. In fact, it is one of the reasons the franchise has such a rabid fanbase. However, the high difficulty has always been a barrier for more casual users. Thankfully, Devil May Cry 5 caters to players of different skill sets. ‘Human’ difficulty is for folks who just want to enjoy the story, while the default ‘Devil’ difficulty provides a more traditional DMC experience. Those who want the greatest challenges available can unlock higher difficulties such as ‘Dante Must Die’ and ‘Heaven or Hell.’ Even if you’re a scrub like me, I encourage you to try out all of the game’s difficulty settings to see just how challenging things can get.Devil May Cry 5 is a near-perfect Hack-n-Slasher that delivers on almost every front. Those disappointed by DmC: Devil May Cry will find little to complain about. The game has everything fans expect: cool characters, demonic landscapes, terrifying monsters, and over-the-top combos. Both longtime fans and newcomers will find a lot to enjoy with this title. Devil May Cry 5 is definitely another home run from Capcom.Buy Devil May Cry 5 on AmazonMore on Geek.com:These Are the Games You Should Check Out in March 2019Final ‘Devil May Cry 5’ Trailer Spoils the Whole GamePlay These Nintendo Switch Games in 2019 Stay on target ‘Devil May Cry 5’s’ Kylo Ren Mod Is Angst OverloadFinal ‘Devil May Cry 5’ Trailer Spoils the Whole Game last_img read more
