“…First, only data from the Scopus database were obtained, and a few studies that were not included in Scopus were missed. On the other hand, Scopus is the most widely used database for bibliometric analysis 41 - 46 ; data from Scopus might constitute the majority of information to some degree. Second, there were no citation data for recently published studies.…”

Objectives: Coronavirus illness (COVID-19) has been found to alter infected people’s sense of smell and taste. However, the pathobiology of this virus is not yet known. Therefore, it is critical to investigate the influence of COVID-19 infection on olfactory and gustatory processes. Therefore, we use bibliometric analysis on COVID-19 and olfactory and/or gustatory dysfunction publications to provide studies perspective. Methods: A bibliometric literature search was performed in the Scopus database. The number and type of publications, countries for publications, institutional sources for publications, journals for publications, citation patterns, and funding agencies were analyzed using Microsoft Excel or VOSviewer. In addition, the VOSviewer 1.6.17 software was used to analyze and visualize hotspots and collaboration patterns between countries. Results: Scopus has published 187 088 documents for COVID-19 in all study fields at the time of data collection (July 26, 2021). A total of 1740 documents related to olfactory and/or gustatory dysfunction were recovered. The countries most relevant by the number of publications were the United States (n = 362, 20.80%), Italy (n = 255, 14.66%), and the United Kingdom (n = 173, 9.94%). By analyzing the terms in the titles and abstracts, we identified 2 clusters related to olfactory and/or gustatory dysfunction research, which are “diagnosis and test methods” and “prognosis and complications of the disease.” Conclusions: This is the first bibliometric analysis of publications related to COVID-19 and olfactory and/or gustatory dysfunction. This study provides academics and researchers with useful information on the publishing patterns of the most influential publications on COVID-19 and olfactory and/or gustatory dysfunction. Olfactory and/or gustatory dysfunction as indices of suspicion for the empirical diagnosis of coronavirus infection is a new hotspot in this field.

Innovation is a significant method of ensuring excellence and competitiveness for contemporary organizations. Therefore, employees are highly motivated to involve in innovative behavior which comprises developing novel and beneficial ideas, sharing ideas of your own or other people to colleagues, and putting those ideas into practice. This bibliometric analysis aims to have a deeper understanding and an advanced knowledge about “innovative behavior” both theoretical and recent research developments using the Scopus database. The study was carried out to see the patterns in publication between 1961 and 2019; authors, journals, countries, academic discipline, research institutes/universities, and various keywords relevant to “innovative behavior” were used as search words. After thorough consideration and the use of multiple checkpoints to remove irrelevant studies, 931 research papers were reviewed. In the analysis of authors’ keywords “innovation” was the most frequently occurred among other keywords. The data has shown a stronger link between “innovative behavior” and “innovation” with 34 occurrences. We noticed that “innovative behavior” has the highest occurrence with 264 times with 37 links and 235 total link strength in which the innovative behavior links with some variables such as leadership, organizational commitment, knowledge sharing, entrepreneurship, psychological empowerment, organizational culture, work engagement, innovative climate, and employee behavior. These are the major concepts that occurred within “innovative behavior” research. Along with future guidelines and study limitations, certain variables with infrequent occurrences are also discussed.

“…To handle this problem and to be able to implement the membranes at the industrial level, competing with cryogenics and pressure swing adsorption, it is necessary to maximize the surface-to-volume ratio, as well as working with high pressures [ 13 , 14 ]. Is for that reasons that important efforts are being made in this field for the development of new polymeric materials and their implementation in hollow fiber membrane modules [ 15 , 16 , 17 ].…”

Thin-Film Composite Matrimid-Based Hollow Fiber Membranes for Oxygen/Nitrogen Separation by Gas Permeation

et al. 2023

In recent years, the need to reduce energy consumption worldwide to move towards sustainable development has led many of the conventional technologies used in the industry to evolve or to be replaced by new alternatives. Oxygen is a compound with diverse industrial and medical applications. For this reason, obtaining it from air is one of the most interesting separations, traditionally performed by cryogenic distillation and pressure swing adsorption, two techniques which are very energetically expensive. In this sense, the implementation of membranes in a hollow fiber configuration is presented as a much more efficient alternative to carry out this separation. The aim of this work is to develop cost-effective multilayer hollow fiber composite membranes made of Matrimid and polydimethylsiloxane (PDMS) for the separation of oxygen and nitrogen from air. PDMS is used as a cover layer but can also enhance the performance of the membrane. In order to compare these two materials, three different configurations are studied. First, integral asymmetric Matrimid hollow fiber membranes were produced using the spinning method. Secondly, by using dip-coating method, a PDMS dense selective layer was deposited on a self-made polyvinylidene fluoride (PVDF) hollow fiber support. Finally, the performance of a dual-layer hollow fiber membrane of Matrimid and PDMS was studied. Membrane morphology was characterized by SEM and separation performance of the membranes was evaluated by mixed-gas permeation experiments. The novelty presented in this work is the manufacture of hollow fiber membranes and the way Matrimid is treated. This makes it possible to develop much thinner dense layers than in the case of flat-sheet membranes, which leads to higher permeance values. This is a key factor when implementing this technology on an industrial scale. Membranes prepared in this work were compared to the current state of the art, reporting quite good performance for the dual-layer membrane, reaching O2 permeance of 30.8 GPU and O2/N2 selectivity of 4.7, with a thickness of about 5–10 μm (counting both selective layers). In addition, the effect of operating temperature on the membrane permeances has been studied experimentally; we analyze its influence on the selectivity of the separation process.
