无知？这很好！

如果你知道如何利用无知,无知就不是坏事。英国造船专家8个月造一艘船,这个美国土老板两周就能做出来。靠的就是无知！     

技术转移:企业资助的学术发明对创新的促进

<正>一般认为企业资助的学术研究对其他人来说是不太容易获取且用处不大的,布莱恩D.怀特及其同事提出的数据对这个看法提出了挑战。政府长期以来一直鼓励大学—企业之间的合作,以期对可以带来工作机会、强化投资并生产出改善生活质量产品的创新进行激励。同时,政府在科学上预算的收缩迫使大学通过其他途径寻求经费支持。根据美国国家科学基金会的统计,2012年由企业提供的科研经费只占到美国研究型大学年度科研经费的5%(大约32亿美元)。     

转移过程对CVD生长的石墨烯质量的影响

利用化学气象沉淀法(CVD)在金属衬底上生长的石墨烯制备电子器件需要先把石墨烯转移到绝缘基底上,转移过程对器件制备的成功率和性能的均匀性有重要影响.转移过程中导致的石墨烯破损和金属生长基底残余颗粒污染受到普遍重视,然而由金属基底腐蚀液导致的石墨烯表面污染还没有引起足够的重视.本文利用拉曼光谱和X射线光电子能谱(XPS)证明了转移过程中金属基底腐蚀液会在石墨烯表面引入污染,利用我们发展的"改良的RCA(radio corporation of America)清洗(modified RCA clean)"转移工艺能够有效地去除这种污染.这对提高后续制备的电子器件的性能有重要意义.     

The molecular sociology of the cell

Proteomic studies have yielded detailed lists of the proteins present in a cell. Comparatively little is known, however, about how these proteins interact and are spatially arranged within the 'functional modules' of the cell: that is, the 'molecular sociology' of the cell. This gap is now being bridged by using emerging experimental techniques, such as mass spectrometry of complexes and single-particle cryo-electron microscopy, to complement traditional biochemical and biophysical methods. With the development of integrative computational methods to exploit the data obtained, such hybrid approaches will uncover the molecular architectures, and perhaps even atomic models, of many protein complexes. With these structures in hand, researchers will be poised to use cryo-electron tomography to view protein complexes in action within cells, providing unprecedented insights into protein-interaction networks.
