Publication date: Available online 10 December 2019Source: Progress in Natural Science: Materials InternationalAuthor(s): Ning Ding, Dong-Sheng Geng, Lan Zhou, Zhao-Lin Liu, Ai-Shui Yu, Yun ZongAbstractHuge volume expansion of electrode materials (e.g. 80% for sulfur and 310% for silicon) in the electrochemical lithiation reaction is seen as a root-cause of fast capacity fading of rechargeable lithium batteries. In this work, an effective solution is demonstrated by fabricating thin film sulfur and silicon electrodes with hierarchical structure of sulfur (or silicon) particles sandwiched between adjacent reduced graphene o...

Cationic polymeric nanoformulation: Recent advances in material design for CRISPR/Cas9 gene therapy
Publication date: Available online 10 December 2019Source: Progress in Natural Science: Materials InternationalAuthor(s): Kaifeng Chen, Shan Jiang, Yun Hong, Zibiao Li, Yun-Long Wu, Caisheng WuAbstractCRISPR/Cas9 (clustered regularly interspaced short palindromic repeat/clustered regularly interspaced short palindromic repeat associated proteins 9) gene editing platform is a promising therapeutic tool for genetic disorders, due to its ability to manipulate the pathogenic gene in genomic level and to easily target specific gene by manipulating single-guide RNA. However, its successful delivery remains a challenge. Up to now...

Glass-forming ability, phase formation and mechanical properties of glass-forming Cu-Hf-Zr alloys
We report on a distinct correlation between phase formation and GFA of Cu50Zr50-based alloys. Increasing additions of Hf reduce the thermal stability of the high-temperature B2 Cu(Hf,Zr) phase, while the thermal stability of the corresponding undercooled melt is enhanced. The GFA of these alloy series gradually raises up to 10 at.% Hf, whereas at 20 at.%Hf, the GFA is drastically lowered, since the B2 Cu(Hf,Zr) phase becomes unstable and the precipitation of the low-temperature equilibrium phases is favoured. This interrelation determines the microstructure and results in the formation of Cu-Hf-Zr-based bulk metallic g...

Bandgap energy determination of InAsSb epilayers grown by molecular beam epitaxy on GaAs substrates
Publication date: Available online 12 October 2019Source: Progress in Natural Science: Materials InternationalAuthor(s): K. Murawski, E. Gomółka, M. Kopytko, K. Grodecki, K. Michalczewski, Ł. Kubiszyn, W. Gawron, P. Martyniuk, A. Rogalski, J. PiotrowskiAbstractInAsSb ternary alloys can be considered as an alternative to HgCdTe for mid-wavelength, as well as long-wavelength infrared applications. Its energy bandgap exhibits nonlinearity versus Sb composition, and hence the correct determination of its value is necessary for the effective design and simulation of optoelectronic devices. The commonly used expression ...

The improvement of surface quality and thickness stability of Fe78Si9B13 melt-spun ribbons by melt overheating
Publication date: Available online 4 October 2019Source: Progress in Natural Science: Materials InternationalAuthor(s): Hui Gao, Zongzhen Li, Shaoxiong Zhou, Guangqiang Zhang, Nairi CuiAbstractThe influence of melt overheating on the viscosity of the melt and surface quality of the Fe78Si9B13 melt-spun ribbons have been studied by using oscillating vessel viscometry, X-ray diffraction, transmission electron microscopy, and field emission scanning electron microscopy. A critical temperature Tc (about 1350 °C) of the melt transformation was determined via viscosity measurements during overheating and subsequent cooling...

Dynamic recrystallization behavior of the Ti–48Al–2Cr–2Nb alloy during isothermal hot deformation
Publication date: Available online 3 October 2019Source: Progress in Natural Science: Materials InternationalAuthor(s): Xiaofei Chen, Bin Tang, Yan Liu, Xiangyi Xue, Lei Li, Hongchao Kou, Jinshan LiAbstractThe hot deformation behavior of the as-cast Ti–48Al–2Cr–2Nb alloy was investigated by isothermal compression tests at deformation temperatures ranging from 1000 °C to 1200 °C, and strain rates from 0.001 s−1 to 0.1 s−1. The single peak stress features common to all flow curves indicate that DRX is the dominating softening mechanism. The calculated values of the hot deformation ac...
