Computational Spectroscopy of the Cr–Cr Bond in Coordination Complexes
, 2021 We report the accurate computational vibrational analysis of the Cr–Cr bond in dichromium complexes using second-order multireference complete active space methods (CASPT2), allowing direct comparison with experimental spectroscopic data both to ...

Small RNA pathways in mammalian oocytes
FEBS Open Bio, EarlyView.Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...

, 2008 利用等离子体发射光谱（ICP-AES），激光拉曼光谱，傅里叶变换红外光谱（FTIR），核磁共振（^1H NMR）分析技术对伯胺在近中性条件下从水溶液中萃取Cr（Ⅵ）的过程进行了研究。ICP-AES对萃取前后水相Cr（Ⅵ）浓度测试结果显示，在近中性条件下，伯胺仍然能够萃取Cr（Ⅵ）。激光拉曼光谱显示，未经酸化的伯胺从近中性水溶液中萃取Cr（Ⅵ）后在890cm^-1处出现新峰。红外光谱显示在近中性条件下直接使用伯胺萃取Cr（Ⅵ）与经酸化处理后按离子交换历程萃取的萃取机理不同，Cr（Ⅵ ...

Transcripts enriched in codons that trigger P‐site tRNA‐mediated mRNA decay possess stable mRNA
FEBS Open Bio, EarlyView.PTMD codons were first described by Mendel et al. as mediators of an mRNA decay pathway dependent on the human protein CNOT3, homologous to yeast Not5. Our findings confirm that PTMD codons destabilize transcripts; however, unlike in yeast, the human pathway specifically targets and slightly destabilizes primarily stable mRNAs.

Gongye shui chuli, 2002 研究了碳钢在臭氧和Cr(Ⅵ)溶液中的腐蚀速率。试验结果表明，臭氧和Cr(Ⅵ)具有良好的协同缓蚀作用。这种协同缓蚀作用与臭氧质量浓度和Cr(Ⅵ)质量浓度有关，Cr(Ⅵ)质量浓度升高，协同缓蚀效果提高;协同缓蚀作用的最佳臭氧质量浓度范围为0。05～0。1mgL。在最佳臭氧质量浓度范围内，当Cr(Ⅵ)为2。5～5。0mgL时，碳钢可以取得较好的缓蚀效果。采用铬酸盐对碳钢进行预膜，可以有效提高臭氧与Cr(Ⅵ)的协同缓蚀效果。
