海外TECH	Engadget	Scientists develop 'nanosphere' paint that could reduce planes' carbon dioxide emissions	https://www.engadget.com/scientists-develop-nanosphere-paint-that-could-reduce-planes-carbon-dioxide-emissions-134733040.html?src=rss	Paint might not seem like the heaviest component to consider when building a large device like an airplane but its mass can add up Now a new and lightweight substance could provide a welcome substitute Two material scientists from Kobe University Fujii Minoru and Sugimoto Hiroshi have discovered nanospheres that are near invisible silicone crystals The particles can reflect light thanks to very large and efficient scattering research published in the journal of ACS Applied Nano Matter details The result could mean covering a surface in vibrant color while only adding percent of the weight that paint would bring Fast Company reports This reduction could have a tremendous impact on factors such as cost and carbon dioxide produced Simply put a plane must use more fuel as its weight goes up thus directly increasing the amount of money airlines spend and then charge customers along with the quantity of fuel burned as carbon dioxide into the atmosphere Minoru and Hiroshi s discovery focuses on structural rather than pigment color to exhibit and maintain hues The former absorbs wavelengths while reflecting the ones the human eye picks up Structural colors on the other hand are intense and bright colors result from the interaction of light with periodic micro and nanostructures that cause color by interference coherent scattering or diffraction according to the Encyclopedia of Nanotechnology The team s work follows previous research in which they were able to build nanocrystals to a specific size Then came the creation of colloquial suspension which keeps the crystalline silicon nanoparticles mixed with supporting liquid rather than separating At present the color of the nanosphere based ink varies as the team changes the nanocrystals sizes Larger particles create warm hues like red while smaller particles display cooler tones like blue These shades should remain identical no matter the angle at which a person sees them This article originally appeared on Engadget at	2024-02-22 13:47:33
海外TECH	Engadget	Xiaomi 14 Ultra combines a 1-inch camera sensor with four AI imaging models	https://www.engadget.com/xiaomi-14-ultra-combines-a-1-inch-camera-sensor-with-four-ai-imaging-models-131127654.html?src=rss	Xiaomi just couldn t wait until MWC to unveil its latest Leica endorsed flagship phone Following the S Ultra and Ultra Xiaomi is finally catching up with the competition by picking up Sony s second gen inch mobile camera sensor the LYT for its brand new Ultra flagship phone This marks the second device to don this cr me de la cr me of imaging silicons after Oppo s Hasselblad tuned Find X Ultra from early January That said the Xiaomi Ultra does have a slight edge with its faster main variable aperture at up to f beating the Find X Ultra s f ーon paper at least With the exception of the faster f aperture on the new mm periscope shooter the remaining three Summilux rear cameras are almost identical to the previous set and they are still powered by a Sony IMX sensor each The biggest change in this field is the new Xiaomi AISP neural chip which claims to be the world s first AI large model computational platform for photography This leverages four large models ー quot FusionLM quot quot ToneLM quot quot ColorLM quot and quot PortraitLM quot ーto fine tune results especially with digital zoom at x or more XiaomiThe Ultra also packs some surprises in the battery durability and connectivity categories As seen in the super slim Mix Fold and Honor Magic V the Ultra is Xiaomi s first candybar to jump onto the silicon carbon cell bandwagon in order to pack mAh of juice into a space that s percent smaller Xiaomi claims that compared to the previous model you get percent more stamina with this battery upgrade To replenish the battery you get both W of wired fast charging and W of wireless fast charging ーthese take minutes and minutes to reach percent respectively Going along with the quot Year of the Dragon quot theme Xiaomi claims that the Ultra s quot Dragon Armor quot structure has double the bending resistance thanks to its special quot M quot aluminum alloy mid frame supposedly crafted with a better grip as well The Chinese brand even claims that this part is percent stronger than the iPhone Pro s titanium frame quot aluminum alloy mid frame supposedly crafted with a better grip as well The Chinese brand even claims that this part is percent stronger than the iPhone Pro s titanium frame but it decided to offer a more premium titanium version as well XiaomiThis metallic frame is complemented by a quot Dragon Crystal quot glass ーshielding the inch AMOLED screen x Hz made by TCL CSOT ーwith apparently times more drop resistance Xiaomi also touts its new vegan leather material which has been certified by SGS to have six times more wear resistance has more dirt resistance and is less prone to yellowing due to ultraviolet rays ーan important breakthrough particularly for the white version But if you prefer something shiny the Ultra is also available in a blue quot Dragon Crystal quot ceramic flavor which resembles ceramic but isn t as heavy ーit only weighs grams more than its vegan leather counterpart Regardless of the cover material this device has IP rating for dust and water resistance Much like the and Pro from October and the SU electric sedan s in car entertainment system the Ultra runs on Xiaomi s Android based HyperOS and it s powered by Qualcomm s latest Snapdragon Gen processor This is cooled by a dual loop vapor chamber which also sucks heat out of the camera modules The processor is backed by Xiaomi s new proprietary chip the Surge T which apparently boosts cellular connectivity by up to percent as well as Wi Fi and Bluetooth connections by up to percent XiaomiThis device also supports two way satellite calling and texting now with percent faster satellite locking and percent faster satellite connection As a bonus when you re lost you can send your location data along with vital signs from your wearable device ーpresumably exclusive to one of the latest Xiaomi watches or smart bands Sadly these satellite features are likely limited to China for now We ll likely be hearing about the Xiaomi Ultra s global launch at MWC next week but for now we can refer to the Chinese pre order pricing The vegan leather and ceramic variants all start from yuan about for the GB of RAM and GB of storage configuration and max out at yuan with GB of RAM and TB of storage These will be available for retail from February The titanium version with dark gray vegan leather is based on the top configuration but costs an extra yuan and it won t be available until March XiaomiLikes its predecessor the Ultra has an optional photography kit with a shutter button grip that adds an extra mAh of power The upgrade this time is the new video recording button along with a customizable jog dial You can get this accessory for yuan as a bundle with the phone This article originally appeared on Engadget at	2024-02-22 13:11:28
