Trial by fire: are the crystals macromolecules?
نویسندگان
چکیده
Protein crystallization screens frequently yield salt crystals as well as protein crystals. A simple method for determining whether a crystal is composed of salt or macromolecules is suggested. A drop containing one or more crystals is transferred to a glass cover slip and the cover slip is then passed through the flame of a Bunsen burner. Macromolecule crystals are destroyed by this treatment, while salt crystals generally remain. The test can be performed after other commonly used tests such as crushing and staining.

A Systematic Approach to Photonic Crystal Based Metamaterial Design
Photonic crystal design procedure for negative refraction has so far been based on trial and error. In this paper, for the first time, a novel and systematic design procedure based on physical and mathematical properties of photonic crystals is proposed to design crystal equi-frequency contours (EFCs) to produce negative refraction. The EFC design is performed by the help of rectangular stair-c...

We investigate the transmission behavior of photonic crystals power splitter by using improved 2D FDTD and MMP methods. The Comparison between experimental data and simulation results are discussed in TE polarization. In this study, the 60° photonic crystal power splitter is optimized, which is composed of InPGaAs/InP material and air holes. The photonic crystal waveguide bend transmission ...
متن کاملInteractions of Various Skeletal Intracrystalline Components with Calcite Crystals
The calcitic skeletal elements of many organisms contain small amounts of proteins and glycoproteins which are incorporated within single crystals of calcite. Extraction and partial purification of the intracrystalline macromolecules allowed the identification of their interactions with synthetic calcite crystals. Specific interactions were inferred from induced morphological modifications asso...
متن کاملCrisis Management in Forest Fire by use of Image Landsat in Model Fire Risk (Case Study: Bioreh Protected Area, Illam Province)
Forest fire brings forest destruction as an important part of human environments, air pollution, and the loss of wealth and facilities, and endangers the lives of human beings in the vicinity of the forest. It is one of the examples of natural crises and is considered to be a crisis management. Identifying the effective factors in the occurrence of fire and hazard zoning is one of the basic too...
متن کاملMolecular recognition at the interface between crystals and biology: generation, manifestation and detection of chirality at crystal surfaces{
An intimate historical and conceptual association exists between crystals and chirality. Yet the relationships between crystal symmetry and crystal morphology are not fully understood. In biological environments, molecular recognition between biological macromolecules and crystal surfaces can affect crystal morphological symmetry, or can be modulated by the symmetry expressed at the surfaces. T...
