Molecular cloning, expression pattern and comparative analysis of chitin synthase gene B in Spodoptera exigua.
TL;DR: Investigation of the chitin synthase (CHS) gene B of Spodoptera exigua indicated that SeCHSB was specifically expressed in the midgut, and its transcript existed constitutively in theMidgut from the 3rd instar larval stage to prepupae and reached highest expression on the 1st day of the fifth instar Larval stage.

TL;DR: Investigation of a new CHS gene characterized from the beet army worm Spodoptera exigua indicated that SeCHSA mRNA is highly expressed in the early and late stages of each larval instar, and consistently expressed in high level during the pupal stage, suggesting that Se CHS plays an important role in cuticle formation and development of S. exigUA.

TL;DR: Researchers optimize TiAl alloy microstructure to break the high-temperature strength-ductility trade-off, achieving 130MPa yield strength increase and doubled ductility at 750°C through the introduction of pearlitic-like microstructures with twinning-induced plasticity and dislocation jog dragging effects.

The microstructure evolution and tensile properties of Ti–43Al–4Nb–1Mo-0.2B alloy during hot rolling
TL;DR: In this paper , the Schmidt factor was calculated to calculate the formation process of a Z-type lamellar structure at 67.5% deformation strain, and the deformation strength reached 880 MPa with deformation of 60%.
