Gold nanoparticle/nickel oxide/poly(pyrrole-N-propionic acid) hybrid multilayer film: Electrochemical study and its application in biosensing

“…The absorbance peaks observed at 1550 and 1393 cm -1 are attributed to the stretching vibrations of the C-C, C=C and C-N groups in the PPy ring, respectively [60]. The peak at 1181 cm -1 is attributed to C-H or C-N in-plane vibration [61]. The bands at 912 and 771 cm -1 were attributed to the =C-H in-plane vibration and out-of-plane vibration, respectively [62].…”

Improving the Structural Stability of Li‐Rich Layered Cathode Materials by Constructing an Antisite Defect Nanolayer through Polyanion Doping

“…The two semicircles are associated with the lithium ion diffusion resistance (R f ) in solid electrolyte interphase (SEI) and charge transfer resistance (R ct ) in the electrode/SEI, respectively. [44,45] The slope line is due to Li + diffusion in the electrode. [46] The equivalent circuit is shown in the inset of the Figure 7a and the fitting results of pristine LNMO, 2 %-B@LNMO and 3 %-B@LNMO samples are listed in Table 1.…”

Enhancing the thermostability ofRhizopus oryzaelipase by combined mutation of hot-spots and engineering a disulfide bond

“…6,8 Many methods have been developed for the enhancement of enzyme thermostability, including of lipases. [9][10][11][12] Among them, point mutations based on multiple-sequence alignments and the introduction of disulde bonds through in silico design are two common and effective approaches. Based on multiplesequence alignment results, the thermostabilities of fumarase C from Corynebacterium glutamicum, Candida rugosa lipases and Candida albicans lipase Lip5 were successfully enhanced via molecular modication.…”
