EuAl4 possesses the BaAl4 crystal structure type with tetragonal symmetry I4/mmm. It undergoes a charge density wave (CDW) transition at T CDW = 145 K and features four consecutive antiferromagnetic phase transitions below 16 K. Here we use...
The benefits of Cu K β radiation for the single-crystal X-ray structure determination of crystalline sponges [0.03%]
Cu Kβ射线单晶X射线法测定结晶海绵结构的优点
Florian Meurer,Carolina von Essen,Clemens Kühn et al.
Florian Meurer et al.
The crystalline sponge method facilitates the X-ray structure determination of samples that do not crystallize or are too sparsely available to afford viable crystallization. By including these materials in a metal-organic framework, the st...
Spatiotemporal control of l-phenyl-alanine crystallization in microemulsion: the role of water in mediating molecular self-assembly [0.03%]
微乳液中L-苯丙氨酸结晶的时空控制：水在介导分子自组装中的作用
Qi Liu,Jingkang Wang,Xin Huang et al.
Qi Liu et al.
Water confined or constrained in a cellular environment can exhibit a diverse structural and dynamical role and hence will affect the self-assembly behavior of biomolecules. Herein, the role of water in the formation of l-phenyl-alanine cry...
Re-evaluation of protein neutron crystallography with and without X-ray/neutron joint refinement [0.03%]
具有和不具有X射线/中子联合优化的蛋白质中子晶体学的再评价

Takeshi Murakawa et al.
Protein neutron crystallography is a powerful technique to determine the positions of H atoms, providing crucial biochemical information such as the protonation states of catalytic groups and the geometry of hydrogen bonds. Recently, the cr...
New ligand-binding sites identified in the crystal structures of β-lactoglobulin complexes with desipramine [0.03%]
去节后地图平阿片和β-乳球蛋白复合物的晶体结构中鉴定新的配体结合位点
Joanna I Loch,Jakub Barciszewski,Joanna Śliwiak et al.
Joanna I Loch et al.
The homodimeric β-lactoglobulin belongs to the lipocalin family of proteins that transport a wide range of hydrophobic molecules and can be modified by mutagenesis to develop specificity for novel groups of ligands. In this work, new lacto...
