Synthesis and high-temperature ferromagnetism of Fe-doped SiGe diluted magnetic semiconductor thin films.
Li J, Zhang X, Lu J, He W, Nie Y, Peng Y, Xiang G. Li J, et al. Nanoscale. 2023 Feb 2;15(5):2206-2213. doi: 10.1039/d2nr05244j. Nanoscale. 2023. PMID: 36537226
Further analysis suggests that the ferromagnetism comes from a hole-mediated process originating from substitutional Fe dopants in the SiGe matrix and this is enhanced by the tensile strain in the films. The synthesis and high-temperature ferromagnetism of Fe-doped SiGe …

Tunable diameter and spacing of double Ge quantum dots using highly-controllable spacers and selective oxidation of SiGe.
Huang TL, Peng KP, Chen CL, Lin HC, George T, Li PW. Huang TL, et al. Sci Rep. 2019 Aug 5;9(1):11303. doi: 10.1038/s41598-019-47806-0. Sci Rep. 2019. PMID: 31383902 Free PMC article.
Pairs of spherical-shaped Ge QDs were formed by the selective oxidation of poly-SiGe spacer islands at each sidewall corner of the nano-patterned Si(3)N(4)/poly-Si ridges. The diameters of the Ge spherical QDs are essentially determined by geometrical conditions (height, w …

Disruption of Two-component System LytSR Affects Forespore Engulfment in Bacillus thuringiensis.
Peng Q, Wu J, Chen X, Qiu L, Zhang J, Tian H, Song F. Peng Q, et al. Front Cell Infect Microbiol. 2017 Nov 3;7:468. doi: 10.3389/fcimb.2017.00468. eCollection 2017. Front Cell Infect Microbiol. 2017. PMID: 29164075 Free PMC article.
Moreover, the transcription of the lytSR operon is regulated by the mother-cell transcription factor SigE, whereas the transcription of the sporulation gene spoIIP was reduced in the lytSR mutant, as demonstrated with a beta-galactosidase activity assay. ...

Identification and Functional Characterization of Two Homologous SpoVS Proteins Involved in Sporulation of Bacillus thuringiensis.
Liu X, Zhang R, Hou S, Liu H, Wang J, Yu Q, Peng Q, Song F. Liu X, et al. Microbiol Spectr. 2021 Oct 31;9(2):e0088121. doi: 10.1128/Spectrum.00881-21. Epub 2021 Oct 6. Microbiol Spectr. 2021. PMID: 34612699 Free PMC article.
The effect of spoVS1 deletion on polar septum delay and sporulation efficiency could be compensated by spoVS2. beta-Galactosidase activity analysis showed that the expression of pro-sigE and spoIIE decreased to different degrees in the HD(deltaspoVS1) and HD(deltaspoVS2) m …

Characteristics of the sigK Deletion Mutant from Bacillus thuringiensis var. israelensis Strain Bt-59.
Xu L, Han G, Fan X, Lv J, Zhang X, Peng Q, Zhang J, Xu J, Song F. Xu L, et al. Curr Microbiol. 2020 Nov;77(11):3422-3429. doi: 10.1007/s00284-020-02150-9. Epub 2020 Aug 8. Curr Microbiol. 2020. PMID: 32770390
All major insecticidal genes of Bacillus thuringiensis var. israelensis (Bti) are controlled by the sporulation-specific sigma factor Sigma E (sigE), while sigE is negatively regulated by Sigma K (sigK). Therefore, knocking out sigK plays an important role in regula …
