Deposition of ink containing metal particles is possible using inkjet technologies. The purpose of this paper is to show a novel method for deposition of iron microparticles, with an average diameter of 1.24 μm, on a glass substrate that can potentially achieve concentrations of 0.21 per cent or higher.

The method combines drop‐on‐demand (DOD) technology with a creative way of positioning iron microparticles near to the nozzle's print head. The use of ferromagnetic particles allows the control of particle dispersion on the target sample surface. The particles are positioned close to the nozzle using a sharpened steel rod as holder and their alignment is controlled by generating an external magnetic field along the sharpened steel rod.

Successful deposition of iron microparticles with a potential concentration of 0.21 per cent or higher is reported.

The implemented method is restricted to ferromagnetic particles or alloys of ferromagnetic and non‐ferromagnetic materials.

The method described could be integrated to control the deposition of iron microparticles in the production of optoelectronic devices and biosensors. This method speeds up the deposition process due to the higher metal microparticle concentrations achieved.

The deposition method introduced in the paper reached concentrations of 0.084 per cent, similar to the highest concentrations (0.1 per cent) reported with conventional methods (inkjet inks containing metal nanoparticles). It also prevents the blocking of the print head nozzles, thus improving the efficiency of Fe particle deposition.

The purpose of this article is to show how a group of Colombian millennials perceive different aspects of working life and how their ideas about job satisfaction, professional expectations and levels of autonomy are related to contemporary demands about inclusion, diversity, equity, autonomy and control.

With this objective, 167 semi-structured interviews were conducted with millennials who work at 10 Colombian companies from the manufacturing and service sectors, located in the five main cities of the country. With a qualitative approach, in the interviews, the research team used a strategy inspired by the technique of generating visual structures associated with grounded theory.

It is concluded that new generations of Colombian workers know of the importance of rewards and autonomy in work and are more critical and less passive in the face of unhealthy working conditions. At the same time, their conduct and speeches are the consequence of the characteristics of the Colombian labour market. The document responds to the need to deepen the debates on welfare and happiness in organizations and to include the demands of millennials in the reflective and political horizon of the ideas of healthy employment and decent work. In practice, this article seeks to demystify ideas about millennials in Colombia and critically contribute to reflection on intergenerational relations in organizations and salary and welfare models. As a Latin American case, it is an original contribution that avoids the common places and the frivolity with which the insertion of the new generations into the working world has been analysed.
