Cells use molecular chaperones and proteases to implement the essential quality control mechanism of proteins. The DegP (HtrA) protein, for survival Escherichia coli cells at elevated temperatures with homologues found in almost all organisms uniquely has both functions. Here we report a activate functions via formation large cage-like 12- 24-mers after binding substrate Cryo-electron microscopic biochemical studies revealed that oligomers are consistently assembled by blocks trimers,...
Semivolatile organic compounds (SVOCs) are present in many indoor materials. SVOC emissions can be characterized with a critical parameter, y0, the gas-phase concentration equilibrium source material. To reduce required time and improve accuracy of existing methods for measuring we developed new method which uses solid-phase microextraction (SPME) to measure an emitted by material placed sealed chamber. Taking one typical SVOC, di-(2-ethylhexyl) phthalate (DEHP), as example, experimental was...
Abstract A proper amount of excess oxygen plays a significant role in hole‐doped cuprate high‐ T c superconductivity. Here, the dopant Bi 2 Sr CaCu O 8+ δ is directly imaged via integrated differential phase contrast combined with state‐of‐the‐art scanning transmission electron microscopy.

Abstract Flat bands are rare in pristine solids and unstable against electronic correlations or other types of long-range order. Unlike atomic-scale Hubbard systems Moiré materials, where either localized long-ranged, flat band with short-range interactions that do not break symmetry spontaneously less known intriguing. These could bridge the gap between atomic Mott insulators correlated insulators, offering a unique platform to explore their mysterious relation. Using an analytical...
Abstract The quantum phase transition between Z 2 plaquette valence bound solid (PVBS) and superfluid (SF) phases on the planar pyrochlore lattice (square ice) is under debate. To gain a further insight, here, we focus dynamical features of hard-core Bose-Hubbard model this study excitation spectra by combining stochastic analytic continuation Monte Carlo simulation. In both PVBS SF phases, flat band with bow-tie structure observed can be explained certain symmetries. At point, turn to...
We identify a quantum critical point with fractal symmetry whose effective theory eludes the renormalization group framework. consider Newman-Moore model three-body interaction subjected to an external transverse field, which exhibits Kramers-Wannier type self-duality and $Z_2$ Ising charge conserved on subset of sites, i.e., Sierpinski gaskets. Using large-scale Monte Carlo simulations, we continuous phase transition between spontaneous breaking paramagnetic phase. This is characterized by...
Identifying the essence of doped Mott insulators is one major outstanding problems in condensed matter physics and key to understanding high-temperature superconductivity cuprates. We report real space visualization transition Sr1-xLaxCuO2+y cuprate films that cover entire electron- hole-doped regimes. Tunneling conductance measurements directly on cooper-oxide (CuO2) planes reveal a systematic shift Fermi level, while fundamental Mott-Hubbard band structure remains unchanged. This further...
Abstract For cuprate superconductors, a high critical transition temperature ( T c ) can be realized in compounds containing multiple CuO 2 layers the unit cell, while current density J is rarely sustained above liquid nitrogen temperature.
