Phosphoric acid-induced activation of sepiolite for enhanced As(III) adsorption: role of in situ deposition of nano-hydroxyapatite

Zhuangzhuang Tian, Chenchen Lu, Yue Zhou, Yong Zhang & Wei Wei
A simple and effective approach was introduced to modify natural calcium-rich sepiolite (SEP) by in situ deposition of nanosized hydroxyapatite (nHAP) to improve SEP’s surface properties and adsorption potential to aqueous As(III). The obtained SEP-nHAP nanocomposites were characterized by means of X-ray diffraction, FTIR, SEM-EDS, and BET analysis. Adsorption of As(III) on SEP-nHAP was evaluated as a function of pH, contact time, coexisting anions, initial As(III) concentration, and temperature. Results showed that modification of SEP...

Understanding the deep structure use of mobile phones – an attachment perspective

Jie Lou, Lingzhao Deng & Dong Wang
Users rely heavily on mobile phones as multi-purpose devices to support all kinds of tasks. This study conceptualises mobile phone deep structure use and aims at unveiling such behaviour. Towards this end, this study goes beyond the traditional technology usage theories based on rationality and instrumentality. It is replaced by a relationship-based theory, the attachment theory, to investigate how users’ attachment to mobile phones is formed and how such attachment influences mobile phone deep structure...

Xiangli Guo, Linlin Chen, Lidan Wang, Jingping Geng, Tao Wang, Jixiong Hu, Jason Li, Changbai Liu & Hu Wang
Bioactive therapeutic molecules are generally impermeable to the cell membrane, hindering their utility and efficacy. A group of peptides called cell-penetrating peptides (CPPs) were found to have the capability of transporting different types of cargo molecules across the cell membrane. Here, we identified a short peptide named P2, which has a higher proportion of basic residues than the CDN1 (cyclin-dependent kinase inhibitor 1) protein it is derived from, and we used bioinformatic analysis and experimental...
