Recent results on the optical absorption and symmetry of the Np(V) complexes with dicarboxylate and diamide ligands are reviewed. The importance of recognizing the “silent” feature of centrosymmetric Np(V) species in analyzing the absorption spectra and calculating the thermodynamic constants of Np(V) complexes is emphasized.

Electrolyte thermodynamics is considered one of the most challenging areas applied thermodynamics. It an area with a wide range applications in science and engineering. There are numerous models, both activity coefficient models equations state, but despite great successes achievements many for several there little consensus on which more generally applicable approaches. controversial aspects, ...

We present the state of the art on the modern mathematical methods of exploiting the entropy principle in thermomechanics of continuous media. A survey of recent results and conceptual discussions of this topic in some well-known non-equilibrium theories (Classical irreversible thermodynamics CIT, Rational thermodynamics RT, Thermodynamics of irreversible processes TIP, Extended irreversible th...

The Bekenstein-Hawking entropy is a cornerstone of horizon thermodynamics but quantum effects correct it, while inequivalent entropies arise also in non-extensive thermodynamics. Reviewing our previous work, we advocate for new construct that comprises recent and older proposals satisfies four minimal key properties. proposal then applied to black holes holographic dark energy shown have the po...

background: development of safe radioprotector is a challenging task. in this study radioprotective effect of sucrose has been demonstrated in calf thymus dna (ctdna). sucrose is a free radical scavenger and also acts as osmolyte and therefore can influence the water activity around dna and effects of radiation on dna. hoechst 33258 was used to probe the possible alteration in physicochemical p...

a good understanding of adsorption equilibrium and thermodynamics is required to design and operate an adsorption process. this study was conducted to assess the adsorption percentage of pb2+ ions as a function of contact time, solution ph and temperatures, and adsorbent dosage through a series of batch experiments. the methods including zeta potentials, specific surface area measurements and t...

Entanglement entropy is a statistical entropy measuring information loss due to coarse-graining corresponding to a spatial division of a system. In this paper we construct a thermodynamics (entanglement thermodynamics) which includes the entanglement entropy as the entropy variable, for a massless scalar field in Minkowski, Schwarzschild and Reissner-Nordström spacetimes to understand the stati...

The understanding of finite temperature behavior of magnetic materials is of vital importance for spintronic applications. In this dissertation different theoretical techniques for studying magnetic thermodynamics of various materials are discussed. Cr 2 O 3 is an antiferromagnetic insulator that was proposed to be a key component of new spintronic devices. The magnetic properties of Cr 2 O 3 w...
