Authors: Vilela Nágila Giovanna Silva , Costa Lucas dos Santos , Santos Jhunior Ronaldo de Oliveira , Olar Adrian Ilie 
Published: February 2022

Purpose — The purpose of this paper is to examine gender differences between men and women on the factors that make an organization an excellent place to work. It is assumed that these factors are tangible or intangible. Design/methodology/approach — Secondary data from 4460 workers in the construction sector who responded to the Best Companies to Work 2017 survey were used. The data were analyzed using descriptive statistics and Multinomial Logistic Regression. From the consideration of ten intangible aspects and one tangible aspect, differences between men and women were perceived in the definition of an excellent place to work. Findings — When compared to men, women are more likely to consider intangible aspects (six out of ten) than tangible in defining an excellent place to work. The other four intangible factors did not show significant differences between genders. Practical implications — This research results can be useful for employers and managers, who should seek measures that contribute to making work more interesting and engaging for all workers. Social implications — We seek to contribute to a better understanding of the gender differences associated with the workplace of a predominantly male environment. The social implications are associated with the need to highlight that inequality in the work environment is lingering still. Originality/value — Despite the presence of progress in equalizing labor rights, there is still a long way to go and this research seeks to highlight this issue based on the analysis of reliable data.

Authors: Vasconcelos Ieda Maria Pereira , De Muylder Cristiana Fernandes 
Published: February 2022

Purpose: The problem of this research was: What correlation between the deficit of basic sanitation and treated water in Brazil with the incidence and number of deaths caused by covid-19 disease? The aim of this article was to analyze the correlation between the number of cases in COVID-19 with the statistics of basic sanitation and treated water supply and institutional voids. Methodology: The research is descriptive and uses techniques of correlation statistical analysis of secondary data. Findings: Statistical calculations show a strong correlation of the variables. The incidence of the disease caused by the new Coronavirus SARS-CoV2, COVID-19 is associated with a lower percentage of the population served by sewage network and water network. It was also demonstrated that the mortality of the disease is strongly associated with a lower percentage of the population served by sewage and water networks, thus indicating a relationship with the theory of Institutional Voids (North, 1990; Douglass & North, 1991; Khanna, Palepu, & Sinha, 2005; Khanna & Palepu, 2010; Rodrigues, 2013). Originality: It was observed that, in general, the highest number of deaths due to the disease related to the states of the federation/macro-regions with the lowest percentages of care to the aforementioned networks, with some exceptions. Soon it was possible to use the theory of Institutional Voids in the analysis of Brazil in the face of basic sanitation indicators, thus indicating the absence of a social public policy appropriate to the well-being of the population.

Published: February 2022

AbstractCalcium sulfate is an important construction material. More than 1600 million square meters of interior surfaces are covered with plasterboards in Europe each year. Plasterboard is manufactured by transforming mined or recycled gypsum (CaSO4 × 2 H2O) to bassanite (CaSO4 × ½H2O) in a time‐ and energy‐consuming heating process. A fast and sustainable way to produce bassanite by solvent‐assisted milling, thereby eliminating the need for energy‐intensive dehydration, is described. The milling reaction is complete after ≈200 min. Kinetic studies revealed that gypsum crystals transform to bassanite by shear forces during milling. 1H nuclear magnetic resonance (NMR) spectroscopic techniques and Fourier‐transform infrared spectroscopy (FT‐IR) show that the resulting bassanite nanocrystals are stabilized by surface functionalization with the auxiliary solvent methanol. Bassanite particles produced over extended milling times of 990 min form long‐term stable dispersions without stabilizers and no signs of precipitation. Addition of water to bassanite leads to instant agglomeration, followed by a phase change to gypsum. The dispersibility in volatile methanol and the elucidation of the crystallization mechanism allow also for applications of the bassanite nanocrystals in hybrid materials.

Published: February 2022

AbstractThe field of bioprinting has made significant advancements in recent years and allowed for the precise deposition of biomaterials and cells. However, within this field lies a major challenge, which is developing high resolution constructs, with complex architectures. In an effort to overcome these challenges a biofabrication technique known as vat polymerization is being increasingly investigated due to its high fabrication accuracy and control of resolution (µm scale). Despite the progress made in developing hydrogel precursors for bioprinting techniques, such as extrusion‐based bioprinting, there is a major lack in developing hydrogel precursor bioresins for vat polymerization. This is due to the specific unique properties and characteristics required for vat polymerization, from lithography to the latest volumetric printing. This is of major concern as the shortage of bioresins available has a significant impact on progressing this technology and exploring its full potential, including speed, resolution, and scale. Therefore, this review discusses the key requirements that need to be addressed in successfully developing a bioresin. The influence of monomer architecture and bioresin composition on printability is described, along with key fundamental parameters that can be altered to increase printing accuracy. Finally, recent advancements in bioresins are discussed together with future directions.

Published: February 2022

AbstractOn‐chip integrated micro‐ and nanoscale vortex lasers are key elements for addressing the exponentially growing demand for information capacity. Although tunable vortex microlasers have been reported, each laser pulse still possesses one particular topological charge and requires additional multiplexing. In this study, the simultaneous generation of coherent laser arrays with different topological charges by combining metalenses with semiconductor microlasers is demonstrated. A TiO2 vortex metalens converts two orbital angular momentum beams into the same diffraction‐limit spot with opposite circular polarizations through spin‐to‐orbital conversion. Consequently, the microlaser emission at the focal spot, which can be decomposed into two circularly polarized beams, is collimated into vortex microlaser beams with two different topological charges through a time‐reversal process. This concept is extended to a 2 × 2 metalens array by introducing off‐axis terms, and eight topological charges are produced simultaneously. This research is a significant step toward the on‐chip integration of micro‐ and nanolasers.

AbstractHigh‐temperature‐induced fire is an extremely serious safety risk in energy storage devices; which can be avoided by replacing their components with nonflammable materials. However; these devices are still destroyed by the high‐temperature decomposition; lacking reliability. Here, a fire‐tolerant supercapacitor is further demonstrated that recovers after burning with a self‐healable “solute‐in‐air” electrolyte. Using fire‐tolerant electrodes and separator with a semiopen device configuration; hygroscopic CaCl2 in the air (“CaCl2‐in‐air”) is designed as a self‐healable electrolyte; which loses its water solvent at high temperatures but spontaneously absorbs water from the air to recover by itself at low temperatures. The supercapacitor is disenabled at 500 °C; while it recovers after cooling in the air. Especially; it even recovers after burning at around 647 °C with enhanced performance. The study offers a self‐healing strategy to design high‐safety; high‐reliability; and fire‐tolerant supercapacitors; which inspires a promising way to deal with general fire‐related risks.
