An approach enabling the acquisition of 2D nuclear magnetic resonance (NMR) spectra within a single scan has been recently proposed. A promising application opened up by this "ultrafast" data acquisition format concerns the monitoring of chemical transformations as they happen, in real time. The present paper illustrates some of this potential with two examples: (i) following an H/D exchange pr...

Materials performance is central to the satisfactory operation of current and future nuclear energy systems due to the severe irradiation environment in reactors. Searching for structural materials with excellent irradiation tolerance is crucial for developing the next generation nuclear reactors. Here, we report the irradiation responses of a novel multi-component alloy system, high entropy al...

Proline-tyrosine nuclear localization signals (PY-NLSs) are recognized and transported into the nucleus by human Karyopherin (Kap) beta2/Transportin and yeast Kap104p. Multipartite PY-NLSs are highly diverse in sequence and structure, share a common C-terminal R/H/KX2-5PY motif, and can be subdivided into hydrophobic and basic subclasses based on loose N-terminal sequence motifs. PY-NLS variabi...

We present the recent progress of hybrid quark-meson-nucleon model for multi-messenger astronomy that unifies thermodynamics quark and hadronic degrees freedom. The obtained equation state is in accordance with nuclear matter properties at saturation density flow constraint from heavy ion collision experiments. mass-radius relations tidal deformabilities compact stars are calculated compared la...

PHYSICS Microcanonical Thermostatistics, the basis for a New Thermodynamics, " heat can flow from cold to hot " , and nuclear multifragmentation. The correct treatment of Phase Separation after 150 years of statistical mechanics a Abstract. Equilibrium statistics of finite Hamiltonian systems is fundamentally described by the microcanonical ensemble (ME) [1]. Canonical, or grand-canonical parti...

Applying the laws of thermodynamics, a general energy approach is formulated to study delayed fracture structural materials under action force load (static, cyclic, shunting mode its change), high temperatures, hydrogen-corrosive media, neutron irradiation. Based on process, models and forecasting methods residual resource elements in mentioned operating conditions are developed. basic concepts...

The unique feature of electrochemistry is the ability to control reaction thermodynamics and kinetics by application electrode potential. Recently, theoretical methods computational approaches within grand canonical ensemble (GCE) have enabled explicitly include potential in first principles calculations. In this review, recent advances future promises GCE density functional theory rate are dis...

The future singularities are possible in a universe that is described by F(R) theory. In previous studies the occurrence of the singularities in F(R) theory have been considered by using a special function for the Hubble parameter and calculating the F(R) function for each of the singularities. Using the specified Hubble parameter causes some difficulties in the study of the second law of therm...
