2‐Furanylboronic acid has been identified as an inexpensive and effective catalyst for the dehydrative amide formation of carboxylic acids and amines. This transformation can be efficiently carried out at room temperature and is applicable to a wide range of carboxylic acids with primary and secondary amines to afford amides in good to excellent yields.

The poor quality of labor causes low productivity and competitiveness. The objective of this study was to mediate the effect of labor absorption on economic growth in the tourism area of Lombok island. This study used the total population of the Lombok island community in three popular destinations to date among others are Senggigi Beach, Kuta Beach Lombok, and Gili Trawangan Beach with a total of 275.267 respondents. This study used random sampling because the total population is more than 100 respondents. The result found that direct or indirect effects in mediating labor absorption towards economic growth in the tourism area of Lombok island are great. Other results showed a strong indicator in each variable that affects labor absorption towards economic growth in the tourism area of Lombok island namely having the skills and fair business competition

With the increasing internet literacy, the prospect of online marketing is increasing. There are millions of people online any time and they all are a potential consumer in the online market. Since there are so many providers, the most important thing for organizations is to understand what are consumer wants and needs in this competitive business environment. Customer buying behaviors are influenced by different factors such as culture, social class, references group relation, family, salary level and salary independency, age, gender etc. and so they show different customer behaviors. These studies explain online shopping important and consumer buying behavior in online shopping.

Polyindole (PIn) is hetroatomic organic molecule which belongs to the fused-ring family have emerged in the past several decades as promising materials due to their unique physical and electrochemical properties. PIn was successfully synthesized by chemical polymerization of indole. Properties of PIn can be improved by mixing polymer with conducting metals, metal oxide, carbon nanocomposites and other materials. Polyindole nanocomposites (PNCs) were characterized through various spectral, thermal and electrical methods. FT-IR (Fourier transform infrared spectroscopy) spectra confirmed the formation of PNCs and SEM (Scanning electron microscopy) reveal the microstructure of surface of PNCs. Thermal characterization revealed that thermal stability of PNCs increases with addition of metal, metal oxide, carbon nanocomposites and other materials. These studies revealed that PNCs of PIn with other metals have an important influence on supercapacitors electrochemical devices, catalysis, anticorrosion, diodes, sensor and biology related applications. This review provide an overview of the preparation of PIn and their composites, followed by their application in various fields with future perspectives.
