Structural Characterisation of Asphaltenes during Residue Hydrotreatment with Light Cycle Oil as an Additive by Yong-Jun Liu, Zhi-Feng Li

“…The findings imply that LCO added to AR during hydrotreating improves the degree of aromatic substitution, the total hydrogen/carbon atomic ratio per average molecule, the distance between aromatic sheets and aliphatic chains, and so forth, by modifying the colloidal nature and microstructure of asphaltene: this is beneficial for the further hydroprocessing of AR. …”

Improving oxidation resistance property of single-crystal Ni-based superalloy via utilizing high temperature aging-induced dislocations by Boxuan Du, Yi Ru, Jiao Wen, Xuetao Li, Yang Cao, Yunpeng Hu, Fan Yang, Yanling Pei, Shusuo Li, Shengkai Gong

“…Taking advantage of such dislocations, the sample aged exhibited an extremely low oxidation rate, and a protective α-Al2O3 layer formed rapidly at the surface instead of multilayer oxides without the aid of aging dislocations, determining the change in oxidation mechanism. The atomic-scale investigation revealed that the Al had a higher activity in aged specimens, and the dislocation from aging treatment enabled the pipe diffusion effect. …”

Bottom-up fabrication of 2D Rydberg exciton arrays in cuprous oxide by Kinjol Barua, Samuel Peana, Arya Deepak Keni, Vahagn Mkhitaryan, Vladimir M. Shalaev, Yong P. Chen, Alexandra Boltasseva, Hadiseh Alaeian

“…Cuprous oxide (Cu2O) has recently emerged as a promising medium for scalable quantum technology due to its high-lying Rydberg excitonic states, akin to those in hydrogen atoms. To harness these nonlinearities for quantum applications, the confinement dimensions must match the Rydberg blockade size, which can reach several microns in Cu2O. …”

AFM observation of protein translocation mediated by one unit of SecYEG-SecA complex by Yui Kanaoka, Takaharu Mori, Wataru Nagaike, Seira Itaya, Yuto Nonaka, Hidetaka Kohga, Takamitsu Haruyama, Yasunori Sugano, Ryoji Miyazaki, Muneyoshi Ichikawa, Takayuki Uchihashi, Tomoya Tsukazaki

“…Here, we visualize the translocation, via one unit of a SecYEG-SecA-embedded nanodisc, of an unfolded substrate protein by high-speed atomic force microscopy (HS-AFM). Additionally, the uniform unidirectional distribution of nanodiscs on a mica substrate enables the HS-AFM image data analysis, revealing dynamic structural changes in the polypeptide-crosslinking domain of SecA between wide-open and closed states depending on nucleotides. …”
