The solvothermal reaction of CuSO·5HO and a chiral -pempH ligand (molar ratio 6 : 1) first forms the metastable intermediate [Cu(OH)(-pempH)(SO)(HO)]·35HO (1), followed by the formation of the stable phase [Cu(OH)(-pempH)(SO)(HO)]·HO (2). Compound 1 displays a novel 3D open-framework structure containing Cu cluster nodes and sulfate links, which can be converted to the layered compound 2. We also investigated the photothermal effects of both compounds.

The metastable crystal structure is difficult to synthesize and maintain but normally acts as special active sites with improved functional properties. Herein, a moderate crystallographic transformation strategy is used to effectively synthesize metastable RuO. By controlling the degree of oxidation, we constructed different heterophase Ru/RuO catalysts.

Although impurities are unavoidable in real-world and experimental systems, most numerical studies on nucleation focus on pure (impurity-free) systems. As a result, the role of impurities in phase transitions remains poorly understood, especially for systems with complex free energy landscapes featuring one or more intermediate metastable phases. In this study, we employed Monte Carlo simulations to investigate the effects of static impurities (quenched disorder) of varying length scales and surface morphologies on the crystal nucleation mechanism and kinetics in the Gaussian core model system-a representative model for soft colloidal systems.

We report the pressure-temperature (-) phase diagram, the origin of the subglass dynamics, and the crystallization kinetics of the biobased polyester poly(ethylene 2,5-furanoate) (PEF), through dielectric spectroscopy (DS) measurements performed as a function of temperature and pressure. The phase diagram comprises four different "phases"; glass, quenched melt, crystalline, and normal melt. The cold crystallization temperature, , increases linearly with pressure (according to the Clausius-Clapeyron equation) as / ∼ 240 K·GPa and is accompanied by a small change in specific volume (Δ = 0.

Viruses may be regarded as dynamic nucleoprotein assemblies capable of assisted multiplication within cells, and of propagation between cells and organisms. Infectious virus particles (virions) assembled in a host cell are dynamic, generally metastable particles: They are robust enough to protect the viral genome outside the cell but are also poised to undergo structural changes and execute mechanochemical actions required for infection of other cells. This chapter provides a broad introduction to the structural and physical biology of viruses and is intended mainly for virology students.

The β-1,4 galactosylation catalyzed by β-1,4 galactosyltransferases (β4Gal-Ts) is not only closely associated with diverse physiological and pathological processes in humans but also widely applied in the -glycan modification of protein glycoengineering. The loop-closing process of β4Gal-Ts is an essential intermediate step intervening in the binding events of donor substrate (UDP-Gal/Mn) and acceptor substrate during its catalytic cycle, with a significant impact on the galactosylation activities. However, the molecular mechanisms in regulating loop-closing dynamics are not entirely clear.
