Electrospinning of polymer nanofibres from multiple jets on a porous tubular surface

Abstract: A novel method for the electrospinning of multiple polymer jets into nanofibres is presented. In this work, 20 wt% nylon 6 solution was electrified and pushed by air pressure through the walls of a porous polyethylene tube. Multiple jets formed on the porous surface and electrospun into nanoscale fibres. The length weighted fibre diameters have a similar mean diameter to those from a single jet but broader in distribution. The mass production rate from the porous tube is 250 times greater than from a typical single jet.

A Comprehensive Mechanistic Model for Upward Two-Phase Flow in Wellbores

Abstract: A comprehensive model is formulated to predict the flow behavior for upward two-phase flow. This model is composed of a model for flow-pattern prediction and a set of independent mechanistic models for predicting such flow characteristics as holdup and pressure drop in bubble, slug, and annular flow. The comprehensive model is evaluated by using a well data bank made up of 1,712 well cases covering a wide variety of field data. Model performance is also compared with six commonly used empirical correlations and the Hasan-Kabir mechanistic model. Overall model performance is in good agreement with the data. In comparison with other methods, the comprehensive model performed the best.

Surface initiated polymerizations from silica nanoparticles

Abstract: Surface initiated polymerizations yield covalently bonded polymer on the substrate. The properties of such nanoparticles are unique finding a wide range of applications. This article reviews the different techniques of synthesis of these hybrid nanoparticles and their mechanistic approach presented in literature.

The bright side of emotional labor

Abstract: Emotional labor (expressing emotions as part of one's job duties, as in “service with a smile”) can be beneficial for employees, organizations, and customers. Meta-analytical summaries reveal that deep acting (summoning up the appropriate feelings one wants to display) generally has positive outcomes. Unlike surface acting (faking emotions), deep acting does not harm employee well-being, and deep acting is positively related with job satisfaction, organizational commitment, job performance, and customer satisfaction. Emerging research also suggests that a third form of emotional labor, natural and genuine emotional labor, is a frequently used emotional labor strategy that has positive effects for both employees and customers. We examine how identity processes shape how employees experience emotional labor, and we maintain that when employees identify with their roles, emotional labor augments and affirms their identity. Person-job fit is an important moderator that influences whether emotional labor enhances or hinders employee well-being. Emotional labor may also have positive outcomes when organizations grant more autonomy and adopt positive display rules that call for the expression of positive emotions. Recent research also indicates that emotional labor strategies may improve leadership effectiveness. Research opportunities on the bright side of emotional labor are abundant.
