1. Organizational Culture and Performance-Based Compensation in Family Firms: Does Family Involvement in Management Matter?
Abstract Purpose This study aims to analyze how different types of organizational culture influence the implementation of performance-based compensation policies in family-owned micro, small and medium-sized enterprises (MSMEs) and whether the presence of the owning family in the management of the firm moderates this relationship. Theoretical framework Cam

2. Effect of Multi-Pass Rolling on the Performance of AZ31 Magnesium Alloy Anode in Mg-Air Battery
In this work, the influence of rolling passes on microstructure, corrosion behavior, electrochemical performance, and battery performance of AZ31 magnesium alloy was studied. The experimental results show that the grain size decreases first and then increases with rolling passes. Among them, the grain size of three passes rolled sample is the smallest, while

4. Manufacturing and characterization of sustainable macroporous glass foams
Abstract This work produced glass foams from soda-lime glass bottles, bentonite, and alumina by the replica method. Compositions with different contents of bentonite (5, 10, 15, and 20 wt%) were prepared and heat-treated at 800 °C. In the alumina-added compositions, 50 wt% of the bentonite was replaced by the alumina. The influences of the content of benton

7. Simple Spectrophotometric Determination of Iron in Diesel Oil after Sample Preparation Employing Extraction Induced by Emulsion Breaking
This work reports the development of a simple and fast method for the spectrophotometric determination of Fe in diesel oil using the classic reaction with 1,10-phenanthroline after its extraction induced by emulsion breaking (EIEB). The extraction parameters of EIEB were optimized (concentration of HNO3 and Triton X-100® in the emulsifying solution) as well

8. Iron Cobaltite (FeCo2O4) Nanocatalysts for Water-Oxidation: Effects of Annealing Temperature on Catalytic Properties
The development of efficient, stable, and non-precious metal water oxidation catalysts (WOCs) is a matter of importance for sustainable energy research. In this work, iron cobaltite (FeCo2O4) nanoparticles were prepared by the coprecipitation method, and we present the effect of heat treatment (250, 350, 450, 650 and 900 °C) on the catalytic properties.

11. Fruit quality and genetic diversity of Spondias dulcis accessions
ABSTRACT Among the less exploited Brazilian native fruit trees, the Spondias dulcis (cajá-manga) has many uses, being their fruits appreciated in fresh consumption and its pulp used in popsicles, ice-creams, and jellies production. However, there is a lack of research on this species, being necessary more studies. This work aimed to characterize the physica

12. Light-Assisted Batch Injection Analysis of Glucose Exploiting a p-n-Homojunction Based on Cu2O
This work describes the development of a photoelectrochemical sensor for glucose quantification exploiting a light assisted-batch injection analysis (BIA) cell. A light-emitting diode (LED) lamp was employed to control the incidence of light on the p-Cu2O/n-Cu2O/fluorine-doped tin oxide (FTO) photoactive platform in BIA cell. The p-Cu2O/n-Cu2O/FTO platform w
