Context:The quality of an Systematic Literature Review (SLR) is as good as the quality of the reviewed papers. Hence, it is vital to rigorously assess the papers included in an SLR. There has been no tertiary study aimed at reporting the state of the practice of quality assessment used in SLRs in Software Engineering (SE). Objective: We aimed to study the practices of quality assessment of the papers included in SLRs in SE. Method: We conducted a tertiary study of the SLRs that have performed quality assessment of the reviewed papers. Results: We identified and analyzed different aspects of the quality assessment of the papers included in 127 SLRs. Conclusion: Researchers use a variety of strategies for quality assessment of the papers reviewed, but report little about the justification for the used criteria. The focus is creditability but not relevance aspect of the papers. Appropriate guidelines are required for devising quality assessment strategies.

Imaging flow cytometry was used to analyze the self assembly of DNA-conjugated polystyrene microspheres. This technique enables quantitative analysis of the assembly process and thereby enables detailed analysis of effect of structural and process variables on the yield of assembly. In a demonstration of the potential of this technique, the influence of DNA strands base pair (bp) length was examined and it was found that 50 bp was sufficient to efficiently drive the assembly of microspheres, forming not only dimers but also chain-like structures. The effect of stoichiometry on yield was also examined. The analysis demonstrated that self assembly of 50 bp microspheres can be driven to near completion by stoichiometric excess in a manner similar to Le Chatelier’s principle in common chemical equilibrium.

Tough and self‐healable substrates can enable stretchable electronics long service life. However, for substrates, it still remains a challenge to achieve both high toughness and autonomous self‐healing ability at room temperature. Herein, a strategy by using the combined effects between quadruple H‐bonding and slidable cross‐links is proposed to solve the above issues in the elastomer. The elastomer exhibits high toughness (77.3 MJ m−3), fracture energy (≈127.2 kJ m−2), and good healing efficiency (91 %) at room temperature. The superior performance is ascribed to the inter and intra crosslinking structures of quadruple H‐bonding and polyrotaxanes in the dual crosslinking system. Strain‐induced crystallization of PEG in polyrotaxanes also contributes to the high fracture energy of the elastomers. Furthermore, based on the dual cross‐linked supramolecular elastomer, a highly stretchable and self‐healable electrode containing liquid metal is also fabricated, retaining resistance stability (0.16–0.26 Ω) even at the strain of 1600 %.
