这是一项关于寻找材料加工技术的任务，要求是要用纳米团簇生产含能材料，这个技术的重点要是在一个可控的过程中进行，要有稳定的空气和粒子率增加一致。 这个任务需要提交一份书面的建议书 Energetic Core-Shell Nanocluster Production AWARD: $20,000 USD | DEADLINE: 11/19/12 | ACTIVE SOLVERS: 116 | POSTED: 9/19/12 Source: InnoCentive Challenge ID: 9932739 Type: Theoretical-licensing Detailed Description & Requirements Background Core-shell nanoclusters are groups of atoms of usually 2 materials in an arrangement such that one material, in the center, is the “core” of atoms which is coated with atoms of another material or the “shell”. These clusters contain from 10’s to millions of atoms and aggregates are in the nanometer range (~5 to 1000 nm). An example would be a core of Fe atoms and a shell of Au atoms. The Fe would not be stable as it would oxidize quite rapidly on its own, but the gold shell protects it from oxidation, yet the small clusters still exhibit magnetic behavior. This is the most simplistic core-shell and there are many different arrangements with multiple materials and multiple shells and the Solvers can look at the references attached for more information. Nanoclusters are unique as they exhibit properties different from bulk materials which are many times cluster size dependent. Of particular interest are highly energetic materials such as mixtures of metals and metal oxides. As nanoclusters, these materials have increased reactivity, because mass transport is removed as a barrier between fuel and oxidizer (i.e. all atoms are in intimate contact). Using the classic thermite reaction, an Al core of atoms could be coated with Fe Oxide which would protect the Al from oxidation. When ignited as nanoclusters the reaction rate would be increased over the bulk materials. The Challenge The Seeker is interested in material processing technologies for the production or fabrication of nano-scale core-shell cluster energetic materials with particle diameters between 5 and 25 nm.

我们需要设计自动崩解控制器用于靶向给药。自动崩解控制器，一旦触发，应该可以在温和条件(生理)下使药物分子的释放并激活。这个我们可以参考数量有限的文献中描述“self-immolative”（自动分解或自毁）连接器，但我们提出的自动崩解控制器不是这样的装置。具体链接为https://www.innocentive.com/ar/challenge/9933733，具体如下： Design of A Self-Cleaving Linker For Targeted Drug Delivery TAGS: Physical Sciences, Novel Molecules, Chemistry, Life Sciences, Theoretical-IP Transfer AWARD: $25,000 USD | DEADLINE: 4/27/15 | ACTIVE SOLVERS: 165 | POSTED: 3/26/15 The Seeker desires the design of a novel self-cleaving linker for use in targeted drug delivery. The self-cleaving linker, once triggered, should allow for the release of molecule(s) of interest under mild (physiological) conditions. A limited number of “self-immolative” linkers are well described in the literature and are specifically excluded from this Challenge. The Seeker specifically encourages synthetic chemists to consider this Challenge even if they do not have medicinal chemistry knowledge. This Challenge requires only a written proposal. Source: InnoCentive Challenge ID: 9933733 Challenge Overview The Seeker desires the design of a novel self-cleaving linker for use in targeted drug delivery. The self-cleaving linker, once triggered, should allow for the release of molecule(s) of interest under mild (physiological) conditions. A limited number of such “self-immolative” linkers, based upon an elimination to generate a quinone methide, or utilizing a 5 or 6 member ring cyclization, are well described in the literature and are specifically excluded from this Challenge. The Seeker specifically encourages synthetic chemists to consider this Challenge even if they do not have medicinal chemistry knowledge. This is a Theoretical Challenge that requires only a written proposal to be submitted. The Challenge award will be contingent upon theoretical evaluation of the proposal by the Seeker. To receive an award, the Solvers will have to transfer to the Seeker their exclusive Intellectual Property   [更多]
