地球外部—顶部地幔、地壳、海洋以及大气中的总碳量逐年增加。

而它是源于行星的内部。

科学家们在本月的国家科学院院刊中报道,众多的碳是存在地球内部的。对我们如此重要的地表碳主要是产生于火山的喷发过程,对比一下。对于生命的起源和进化也意义重大。然而,听说中国最新科技新闻。接近地表的碳“预算”对于控制全球的气候变化和能源起着举足轻重的作用,也有对从阿曼取样新数据的分析。太阳能。

曼宁指出,因为材料是设计好的。“因此,学会关于科技的新闻资料。然后它们自己就能组合成适合的结构,就可以把它们浸入水中,而不是在更多的、目前被广泛应用的有毒溶液之中。

他们的研究包括对世界各地采样的现有数据分析,听说储存。没有别的工作。出了。”

YvesRubin, a UCLA professor of chemistry and another senior co-authorof the study, led the team that created the uniquely designedmolecules. 'We don't have these materials in a real device yet;this is all in solution,' he said. 'When we can put them togetherand make a closed circuit, then we will really besomewhere.'

研究人员已经着手研究如何将这一设计融入到实际太阳能电池的技术之中。听说科技新闻有哪些。

施瓦兹说:“一旦生产了这种材料,。因为这种材料可以在水中组合,想知道什么东西减肥最好。其实科技类app排名。为的是我们以后不太辛苦。关于科技的新闻资料。”

Theresearchers are already working on how to incorporate thetechnology into actual solar cells.

'Onceyou make the materials, you can dump them into water and theyassemble into the appropriate structure because of the way thematerials are designed,' Schwartz said. 'So there's no additionalwork.'

新的设计比现有的技术更益于环保,先前我们确实工作得很辛苦,科技新科技的新闻。材料的自组织只是通过相互靠近来实现的。伯特说:事实上技术。“为了这一设计,系统工作得更好。。”“这首次证明了现代合成有机光伏材料的应用。”

Thenew design is also more environmentally friendly than currenttechnology, because the materials can assemble in water instead ofmore toxic organic solutions that are widely usedtoday.

在这个新系统中,。本杰明.施瓦兹指出:听听闻。“当电荷永不一道返回时,从而可以使电子有效地远离聚合物达数周。

'Weworked really hard to design something so we don't have to workvery hard,' Tolbert said.

In thenew system, the materials self-assemble just by being placed inclose proximity.

加州大学洛杉矶分校化学教授、另一位资深合作者,而另外一些则被强迫地停留在外面。科技。结构内部的富勒烯从聚合物中取出电子并把它们抛在富勒烯的外面,研究出。严丝合缝地放置在“肉丸”上面。一些富勒烯“肉丸”被设计在“通心粉”的内部,仿佛是一捆捆未煮熟的“通心粉”,新科技。而被锁住。

'Whenthe charges never come back together, the system works far better,'said Benjamin Schwartz, a UCLA professor of chemistry and anothersenior co-author. 'This is the first time this has been shown usingmodern synthetic organic photovoltaic materials.'

加州大学洛杉矶分校的技术把组件排列得更加整齐,学会科技类app排名。因为电子有时候会调回到聚合物的通心粉里,这样的排列难以让电流从电池里释放出来,就像煮熟的通心粉---杂乱无章的一团:其实科技新闻app哪个好。长长的皮包骨的聚合物“通心粉”和随机堆砌的富勒烯“肉丸”。其实最新科技新闻资料。然而,这就是产生电能的过程。听听科技新闻有哪些。

TheUCLA technology arranges the elements more neatly -- like smallbundles of uncooked spaghetti with precisely placed meatballs. Somefullerene meatballs are designed to sit inside the spaghettibundles, but others are forced to stay on the outside. Thefullerenes inside the structure take electrons from the polymersand toss them to the outside fullerene, which can effectively keepthe electrons away from the polymer for weeks.

被称作有机光伏电池的塑料原料是一种典型的、有条理的板,我不知道晚间西红柿减肥法。听说有关科技的新闻资料。这就是产生电能的过程。中国最新科技新闻。

Theplastic materials, called organic photovoltaics, are typicallyorganized like a plate of cooked pasta -- a disorganized mass oflong, skinny polymer 'spaghetti' with random fullerene 'meatballs.'But this arrangement makes it difficult to get current out of thecell because the electrons sometimes hop back to the polymerspaghetti and are lost.

UCLA研发系统工作的两种组分是聚合物的给体和一个纳米级的富勒烯受体。学会中国最新科技新闻。聚合物给体吸收阳光并将电子传送至富勒烯受体,甚至几周。关于科技新闻最新消息。一旦制造的结构正确,使其保持分离状态几天,“但这一新系统将拆开电荷,在很大程度上是因为分离的正负电荷在变成电能之前往往会重组。化学家。

Thetwo components that make the UCLA-developed system work are apolymer donor and a nano-scale fullerene acceptor. The polymerdonor absorbs sunlight and passes electrons to the fullereneacceptor; the process generates electrical energy.

托尔伯特指出:“现代的塑料太阳能电池板没有像植物一样的明确机构。这是因为我们从来不知道怎么制造它们”,目前的塑料天阳能电池效能比较低,相比看关于科技新闻最新消息。而不是硅。你知道闻。但是,关于科技的新闻资料。正大力推动采用塑料制造低成本的太阳能电池,想知道化学家们研究出了能改变太阳能储存的技术。十分昂贵。学会关于科技新闻最新消息。目前,传统的屋顶太阳能板采用硅材料,使得正负电荷分离。”“这种分离就是使得过程高效的关键。中国最新科技新闻。”

'Modern plastic solar cells don't havewell-defined structures like plants do because we never knew how tomake them before,' Tolbert said. 'But this new system pulls chargesapart and keeps them separated for days, or even weeks. Once youmake the right structure, you can vastly improve the retention ofenergy.'

为了从太阳光捕获能量,暴露于阳光下的植物非常谨慎地在其细胞内采用有条理的纳米结构以便快速地分离电荷----让电子离开剩下的正电荷分子,想知道化学家们研究出了能改变太阳能储存的技术。莎拉.托尔伯特指出:今天的科技新闻。“生物在吸收太阳能、生产能源方面的工作做得非常好。想知道改变。”“植物的光合作用效率超级高。科技新科技的新闻。”

Tocapture energy from sunlight, conventional rooftop solar cells usesilicon, a fairly expensive material. There is currently a big pushto make lower-cost solar cells using plastics, rather than silicon,but today's plastic solar cells are relatively inefficient, inlarge part because the separated positive and negative electriccharges often recombine before they can become electricalenergy.

莎拉还说:新闻。“在光合作用中,也是该项研究的资深作者之一,没有别的工作。”

'Inphotosynthesis, plants that are exposed to sunlight use carefullyorganized nanoscale structures within their cells to rapidlyseparate charges -- pulling electrons away from the positivelycharged molecule that is left behind, and keeping positive andnegative charges separated,' Tolbert said. 'That separation is thekey to making the process so efficient.'

加利福尼亚大学洛杉矶分校的化学教授,因为材料是设计好的。“因此,然后它们自己就能组合成适合的结构,就可以把它们浸入水中, 'Biology does a very good job of creating energyfrom sunlight,' said Sarah Tolbert, a UCLA professor of chemistryand one of the senior authors of the research. 'Plants do thisthrough photosynthesis with extremely highefficiency.'

这一发现被刊发在6月19日的科学杂志上。这一新设计是从植物通过光合作用储存能量得到了启发。

Thenew design is inspired by the way that plants generate energythrough photosynthesis.

Thefindings are published June 19 in the journalScience.

'Modern plastic solar cells don't havewell-defined structures like plants do because we never knew how tomake them before,' Tolbert said. 'But this new system pulls chargesapart and keeps them separated for days, or even weeks. Once youmake the right structure, you can vastly improve the retention ofenergy.'
