The e-business platform has become a major driver for economic growth and development. The economic success of an e-marketplace greatly depends on the extent to which buyers and sellers are attracted to enter and actively participate in the e-business platform. Existing literature lacks empirical examination of factors influencing e-business platform attractiveness (EBPA) from a seller's perspective and understudies the interplay between technical and managerial considerations.

Based on the literature on network economy, modular systems theory, control theory and social exchange theory, the paper proposed that platform flexibility and platform control (PC) would affect EBPA through both direct and interaction effects. From a survey of platform sellers, the paper explored the influencing mechanisms of EBPA using hierarchical regression and fuzzy-set qualitative comparative analysis (fsQCA) to understand the statistical associations and the set relations of the conjunctions and conditions.

The paper found that platform flexibility (PF), process control and clan control (CC) positively affected EBPA. In addition, the interaction between PF and process control demonstrated a substitution effect on EBPA, and the interaction between PF and CC demonstrated a complementary effect on EBPA. Also, the authors found that the interaction between process control and CC demonstrated a complementary effect on EBPA. fsQCA provided the configurations of causal recipes associated with EBPA.

From a seller's perspective, the paper presents both theoretical explanation and empirical evidence for how design factors (e.g. PF) and governance factors (e.g. process control and CC) may interplay to influence EBPA.

The purpose of this work is to controllably synthesize a carbon aerogel with programmable functionally graded performance via a simple and effective strategy.

This work uses polyvinyl alcohol (PVA) via the controllable sol-gel, lyophilization, and carbonization approach to achieve a programmable carbon aerogel. This design has the advantages of low raw material and preparation cost, simple and controllable synthetic process and low carbonization temperature.

The thermal stability and microstructure of PVA aerogel can be controlled by the crosslinking agent content within a certain range. The crosslinking agent content and the carbonization temperature are the key factors for functionally graded programming of carbon aerogels, including microstructure, oxygen-containing functional groups and adsorption performance. The adsorption ratio and adsorption rate of uranium can be controlled by adjusting initial concentration and pH value of the uranium solution. The 2.5%25 carbon aerogel with carbonization temperature of 350 °C has excellent adsorption performance when the initial concentration of uranium solution is 32 ppm at pH 7.5.

As a new type of lightweight nano-porous amorphous carbon material, this carbon aerogel has many excellent properties.

This work presents a simple, low cost and controllable strategy for functionally graded programming of novel carbon aerogel. This carbon aerogel has great potential for application in various fields such as uranium recovery, wastewater treatment, sound absorption and shock absorption.
