Here, Alertet al. theoretically predict and experimentally verify the unexpected formation of a metastable phase by spinodal decomposition through direct phase separation from an unstable phase.doi:10.1038/ncomms13067Alert, RicardTierno, PietroCasademunt, JaumeNature Publishing GroupNature Communications...
Process Ⅰ: reducing the formation energy barrier of the metastable perovskites by intermediate-phase engineering, strain engineering, and two-step method. Process Ⅱ: decreasing the Gibbs free energy is beneficial for the formation and stabilization of the metastable perovskites. Process Ⅲ: increasing...
Cognitive impairment severity determined the assignment of subjects to either a normal control (NC) group, a subjective cognitive decline (SCD) group, a mild cognitive impairment (MCI) group, or an Alzheimer's disease (AD) group. Subjects with normal cognition who consistently consumed vitamin D,...
Her group studies how the properties of select proteins influence their phase separation and ultimately how this impacts their biological function. She notes that we have a general understanding of how disorder, sequence identity, valency and phase interfaces influence this physical transition. However,...
At (and at any other point of the boundary of ησ), the system is mechanically stable along all but one direction. (Due to point group symmetry, a few directions may simultaneously become unstable at the same point.) Since in the thermodynamic limit (N→∞), the contribution of a ...

This organization corresponds to the formation of blue phases already observed in thermotropic liquid crystals, but never reported in lyotropic systems. In addition, the size of the DNA molecule, about ten times that of most thermotropic materials, allows here the molecular resolution imaging of blue...
The average value of each of the top 12 elements in each record of IM and AM categories in our dataset is shown in Fig.2. Our analysis highlights the pivotal role of Al in the formation of both the BCC and IM phases. Specifically, the average composition of Al in the BCC phase, as...
These generators are divided into two groups: the first group includes the generators which account for the quark-gluon plasma formation during nuclear collisions, while the second group includes the generators which do not assume the quark-gluon plasma formation in such collisions. Comparing the ...
