say, common salt. To contrast the difference, the molecular weight of common salt is only 58.5, while that of a polymer can be as high as several hundred thousand thousands. These big molecules or 'macro-molecules' are made up of much smaller molecules. The small ...
Dye molecules of appropriate size are arranged with their long molecular axis along the one-dimensional channels and they cannot glide past each other. 相关知识点: 试题来源: 解析 适当尺寸的染料分子和长长的分子轴沿一维通道排行,他们互相无法滑动. 分析总结。 适当尺寸的染料分子和长长的分子轴沿一维通道...

Over the past century, more than 100 million small molecules have been synthesized in the search for new drugs and materials1. These efforts have explored only an infinitesimal subset of chemical space, the size of which is estimated at over 1060molecules2. Yet, remarkably and often serendipitous...
Here we report near-infrared observations of Herbig-Haro 211 from the James Webb Space Telescope, an outflow from an analogue of our Sun when it was, at most, a few times 104 years old. These observations reveal copious emission from hot molecules, explaining the origin of the ‘green ...
Atomistic MD simulations were performed on DHA-PC, EPA-PC, DPA-PC and OA-PC bilayers in the absence and presence of 20 mol% cholesterol. They were run in the constant particle number, pressure and temperature (NPT) ensemble. There were 98 PC molecules in the single component membrane simula...
We also elucidate the structural basis underlying the strong interaction between GIT and PIX. Unexpectedly, the GIT1/β-Pix complex undergoes phase separation, forming highly concentrated enzyme condensates in vitro and in living cells without help from additional scaffolding molecules. GIT1/β-Pix ...
