Surface-engineered growth of AgIn₅S₈ crystals.

The growth of semiconductor crystals and thin films plays an essential role in industry and academic research. Considering the environmental damage caused by energy consumption during their fabrication, a simpler and cheaper method is desired. In fact, preparing semiconductor materials at lower temperatures using solution chemistry has potential in this research field.

A phenomenological theory of the anomalous pseudogap phase in underdoped cuprates.

The theoretical description of the anomalous properties of the pseudogap phase in the underdoped region of the cuprate phase diagram lags behind the progress in spectroscopic and other experiments. A phenomenological ansatz, based on analogies to the approach to Mott localization at weak coupling in lower dimensional systems, has been proposed by Yang et al (2006 Phys. Rev.

Andreev and single-particle tunneling spectra of underdoped cuprate superconductors.

We study tunneling spectroscopy between a normal metal and an underdoped cuprate superconductor modeled by a phenomenological theory in which the pseudogap is a precursor to the undoped Mott insulator. In the low barrier tunneling limit, the spectra are enhanced by Andreev reflection only within a voltage region of the small superconducting energy gap. In the high barrier tunneling limit, the spectra show a large energy pseudogap associated with single particle tunneling.

Strong coupling theory for superconducting iron pnictides.

Superconductivity in iron pnictides is studied by using a two-orbital Hubbard model in the large U limit. The Coulomb repulsion induces an orbital-dependent pairing between charge carriers. The pairing is found mainly from the scattering within the same Fermi pocket.

[Oxidative refolding of proteins].

The mechanism of oxidative refolding of proteins was elucidated in more detail from the intensive and extensive studies in the past decades. 1. Most of the proteins examined so far proceed oxidative refolding via multiple pathways rather than a single and specific pathway.

A Comparative Study of Different Types of Rabbit 2',5'-Oligoadenylate Synthetase.

Only one 2',5'-oligoadenylate synthetase (2',5'-OASE) with a mass of 110 kD is present in the NDV-induced rabbit reticulocytes, whereas two 2',5'-OASE isozymes with mass of 110 kD and 40 kD respectively exist in the NDV-treated rabbit spleen. The large 110 kD enzymes from reticulocytes and spleen are associated with the ribosome. The small enzyme from spleen has been found in both the cytosol and ribosomal pellet.

In vivo Induction of Rabbit 2',5'-Oligoadenylate Synthetase.

By the study of in vivo induction of rabbit 2',5'-oligoadenylate synthetase (2',5'-OASE), it has been found that polyinosinic acid-polycytidylic acid (poly(I).poly(C)) can induce the formation of 2',5'-OASE only in rabbit peripheral blood mononuclear cells(PBMC), whereas New Castle disease virus (NDV) and erythropoietin (EPO) are capable of enhancing 2',5'-OASE level in the total red blood capsule (RBC) as well as in PBMC. It has been demonstrated that the enzyme is located in reticulocytes and that the increase of 2',5'-OASE level by phenylhydrazine, NDV, EPO in RBC is proportionally related to the increase of reticulocytes.
