Construction and Immunogenicity Comparison of Three Virus-Like Particles Carrying Different Combinations of Structural Proteins of Avian Coronavirus Infectious Bronchitis Virus.

Infectious bronchitis virus (IBV) poses massive economic losses in the global poultry industry. Here, we firstly report the construction and immunogenicity comparison of virus-like particles (VLPs) carrying the S, M and E proteins (SME-VLPs); VLPs carrying the S and M proteins (SM-VLPs); and VLPs carrying the M and E proteins (ME-VLPs) from the dominant serotype representative strain GX-YL5 in China. The neutralizing antibody response induced by the SME-VLPs was similar to that induced by the inactivated oil vaccine (OEV) of GX-YL5, and higher than those induced by the SM-VLPs, ME-VLPs and commercial live vaccine H120.

Degradation of the transition metal@Pt core-shell nanoparticle catalyst: a DFT study.

Electrocatalysts in acidic media face the issues of inactivation and degradation with complex thermodynamic processes. A density functional theory (DFT) calculation is performed to investigate the galvanic and pitting etching processes of metal@Pt (M@Pt) core-shell nanoparticles (12 transition elements are selected to replace the core atoms). The dissolution process with atomic etching follows the dissolution potential site-dependence phenomena, and the dissolution potential of the Pt shell exhibits a negative linear correlation with the average d-band center of the Pt shell.

Two-Way Shape Memory Effect Induced by Tensile Deformation in Columnar-Grained CuAlMn Alloy.

Columnar-grained CuAlMn shape memory alloy (SMA) was prepared by a directional solidification method and exhibited a high superelasticity of 8.18% and excellent ductility at room temperature, which provided the possibility of obtaining high shape memory. However, proper pre-deformation is an essential part of repeatedly obtaining large and stable shape change.

The stability and catalytic activity of W@Pt core-shell structure.

This paper reports a study of the electronic properties, structural stability and catalytic activity of the W@Pt core-shell structure using the First-principles calculations. The degree of corrosion of W@Pt core-shell structure is simulated in acid solutions and through molecular absorption. The absorption energy of OH for this structure is lower than that for Pt, which inhibits the poison effect of O containing intermediate.
