The aim of this paper is to present results of investigations carried out on the front electrode of solar cells. Nowadays, most worldwide solar cell production is dominated by monocrystalline and polycrystalline silicon as a base material. In such cells, the electrical carriers are collected by the system of metallic paths fabricated on a silicon surface. One possible way to increase cell efficiency and reduce the production costs of solar modules is to replace the expensive silver by cheaper copper in front metallic electrodes.

The paper presents results of investigations performed on the front electrode of the solar cell. The investigations were focused on the modification of typical screen printing fabrication of the thin electrical finger paths of the front solar cell electrode. The resulting contacts were characterized morphologically (the dimensions and geometry of the front contacts) by scanning electron microscopy. The composition of finger path covered with copper was analyzed using energy-dispersive X-ray spectroscopy and X-ray photoelectron spectroscopy techniques.

In this work, the front electrodes were screen printed with the use of conventional silver-paste on a p-type Cz–Si-textured wafer with a n+ emitter and with an antireflection coating. After that, the fired front electrode was electroless coated with copper. The electroless copper deposition was performed in two stages. First, the surface of the photovoltaic cell was dipped in an aqueous solution of CuSO₄ and then dried in air at room temperature. When the surface dried, the cell was immersed in hydrogen fluoride solution (5 per cent) for 1 s followed by rinsing in deionization water.

The experiments confirmed the potential application of copper as an additional layer of the solar cell front metal electrode. On the one hand, this process is very simple and, on the other, the authors demonstrate a problem with the mechanical stability of the covered paths leading to electrode delamination.

The paper aims to show application of the electrochemically deposited coatings for thickening of the screen printed electric paths potentially applied in photovoltaic cells.

The electric paths were screen printed with the use of silver-based paste. The paths were thickened by electrodeposition of thin copper layer in potentiostatic regime from surfactant-free plating bath. The morphology and surface quality of the paths were studied by imaging with scanning electron microscopy.

The electric paths can be thickened successfully, but quality for the screen printed substrate determines quality of deposited layer. The EDX analysis confirmed that the deposited copper layer covered uniformly the printed paths.

The adhesion of the copper-covered path to the silicon wafer surface depends on adhesion of the original screen printed path.

This paper confirms that electrodeposited copper can be applied for screen printed silver paths thickening in a controllable way.

With the aim of developing a better understanding of why some consumers still excuse corporate brands that engage in transgressions, this study tests whether extrinsically religious people tolerate corporate brands more than intrinsically religious individuals at different transgression levels (severe and mild) and punish them less than the latter.

This study adopts a 2 × 2 experimental design to manipulate corporate brand transgression levels (mild vs severe) and religiosity orientations (intrinsically religious vs extrinsically religious) on a convenience sample of 134 subjects who live in Turkey, a country where Islam shapes religious context. It uses a scenario technique and projective approach.

While the main effect of corporate brand transgression on punishing behaviour does not appear in the analysis, religiosity’s main effect on the latter does. Unexpectedly, extrinsically religious consumers punish corporate brand transgressors more than their intrinsically religious counterparts regardless of the transgression severity levels.

Although the study does not refer to any religion in particular, countries predominated by religions other than Islam may yield different consumer reactions. Future studies should focus on transgressions in such different settings.

Corporate brand transgressors should immediately take up good causes to attract the attention of intrinsically religious consumers. Otherwise, for the sake of showing off, extrinsically religious people may punish the transgressor for its intentional mistakes, which may harm corporate brand associations.

This study examines the link between religiosity and corporate branding. Unique in this way, it introduces religiosity as a valid contributor that can explain why some consumers do not punish corporate brand transgressors, especially in countries like Turkey where religiosity is intertwined with the developments in the liberal economy which led to the emergence of a new middle class.

The purpose of this paper is to examine the relationship between management education, the performance of German engineering enterprises and the strategic knowledge status of the executives running those enterprises.

The paper is based upon the results of an online/posted self‐administered questionnaire conducted within Germany, augmented by micro case studies.

Findings suggest that the curricula in German Engineering Faculties fail to fully embrace business and management studies, in particular strategic management which has virtually no presence. Engineers dominate senior management positions within the German machinery and equipment sector yet they display limited knowledge of strategic management tools. There is also evidence that links performance with the application of management knowledge.

The study is limited to senior executives within German SMEs from the machinery and equipment sector. It is likely that the findings would be applicable throughout the German engineering industry; however, generalisability to other countries may be limited. Only a single year's performance (2007) was considered and this is also a limitation of the study. This was mitigated by a request that anomalies be noted, such as extraordinary write offs or a windfall profit, within the year in question, this was then taken into account during the analysis.

Based on the findings it is suggested that German faculties of engineering should enhance and expand management education, particularly strategic management, thus enhancing future performance potential within German SMEs.

This paper examines the level of management education attained by senior engineering executives with a key economic industrial sector in Germany, as such it is one of few such studies which investigates the link between management education and performance.

The purpose of this paper is to provide a selected bibliography of recent resources on library instruction and information literacy.

Introduces and annotates periodical articles, monographs, and audiovisual material examining library instruction and information literacy.

Provides information about each source, discusses the characteristics of current scholarship, and describes sources that contain unique scholarly contributions and quality reproductions.

The information may be used by librarians and interested parties as a quick reference to literature on library instruction and information literacy.

This paper aims to explore to what extent senior executives, particularly within the German machinery and equipment small- and medium-sized enterprises (SMEs), gather and apply knowledge pertaining strategic management (SM) tools. Furthermore, the study aims to provide research evidence as to whether or not the companies derive any performance enhancing benefit from the appliance of said with the knowledge.

The research relied on a self-administered questionnaire mailed or posted to the entire population of about 6,000 enterprises. The resulting data were analyzed with the statistical package for social science (SPSS) statistical software package.

Executives within the sector, especially those with a predominantly engineering background, lack both knowledge and understanding of SM in general and strategic tool-kits in particular. Interestingly, educational background, in association with toolkit usage, appears to enhance organizational performance.

The German educational system, in conjunction with the associated professional development infrastructures, may impact the generalizability of the research findings.

The results from this study can be used for lobbying policy-makers and shapers, e.g. government, higher education, industry and professional bodies, to improve and expand engineering management education so that practitioners have the knowledge of and competency in SM.

The study provides an insight look of how executives in one of Germany’s most successful industries deal with the knowledge and application of SM tools and their impact on performance. Extant research has not dealt with Germany or this sector in relation to the appliance of strategy-related knowledge and performance.

The purpose of this two-part paper is to illustrate how sensors impart robots with perceptive capabilities. This first part considers robots that interact with humans and which seek to mimic human intentions.

Following a short introduction, this paper first discusses the sensors used in robotic prosthetics. It then considers sensor applications in recently developed service, companion and assistive robots. The final section concerns the sensors used in collaborative robots, followed by brief concluding comments.

This shows that sensors play a vital role in imparting perceptive capabilities to robots which interact with people. They can interpret human intentions, control prosthetic limbs, monitor and map a robot’s environment, assist with navigation, ensure the safety of co-workers and even detect a person’s emotional state. They are based on a diversity of principles and technologies, including microelectromechanical system (MEMS)-based sensors for physical variables, myographic electrodes and electroencephalogram (EEG) sensors, lasers, infra-red and sonar systems and sophisticated cameras and imaging systems.

This provides a timely account of how sensors confer perceptive capabilities to the growing number of robots which interact directly with people.

The purpose of this paper is to evaluate the effect of green tea polyphenols addition on physicochemical, microbiological and bioactive characteristics of yogurt.

Two incorporation methods of polyphenols were evaluated: direct addition or incorporated within protein particles of whey protein concentrate and gelatin. During yogurt’s shelf life, structure characteristics (water holding capacity, textural and rheological parameters), lactic acid bacteria (LAB) viability and polyphenols antioxidant activity were analyzed. Also, polyphenol bioaccesibility after in vitro digestion was evaluated.

Polyphenols addition (by the two methods used) did not affect the dynamics of the fermentation process, nor the LAB viability during storage. The color parameter a* for the yogurts with the highest polyphenol concentrations showed positive values (tending to red), but not visible to the naked eye. Because of the ability of polyphenols to interact with milk proteins, yogurts with polyphenols presented higher values in firmness and cohesiveness with respect to the control. Additionally, the incorporation of polyphenols in protein particles increased even more these parameters because of the higher protein content of these formulations. After simulated digestion, a high polyphenol bioaccesibility was observed, and the antioxidant activity was retained, which could be explained by the “protector” effect of the milk matrix.

Yogurt supplementation with green tea polyphenols is feasible for the development of functional food. However, the use of protein particles would not provide an extra benefit because milk proteins already act as protective molecules of polyphenols.

This study shows not only the physico-chemical implications of including polyphenols in yogurt but also their bioaccesibility after an in vitro digestion, revealing a suitable manner for delivery of antioxidants in a dairy product like yogurt.

The purpose of this study is to provide ideas and theoretical guidance for green, environmentally friendly and efficient “bacteriostasis with bacteria” technology.

In this paper, a beneficial strain of bacteria was extracted and purified from marine mud. Weight-loss test, morphological observation and electrochemical test were used to systematically study the effect of sulfate-reducing bacteria (SRB)-induced corrosion inhibition on X65 steel in simulated offshore oil field production water.

The results showed that a beneficial strain was selected and identified as Vibrio alginolyticus. Under the condition of co-culture of SRB, the average corrosion rate of X65 steel was significantly reduced. In the mixed bacterial system, the surface of X65 steel samples was relatively flat, and the structure of biofilm and corrosion product film was dense. The number of corrosion pits, the average diameter and depth of corrosion pits were significantly reduced. The localized corrosion of X65 steel was significantly inhibited.

The complex and changing marine environment makes the corrosion problem of marine steel increasingly severe, and the microbiologically influenced corrosion (MIC) caused by SRB is particularly serious. The research and development of environmentally friendly corrosion protection technology is a long-term and difficult problem. The use of beneficial microorganisms to control MIC is a green and efficient anticorrosion measure. Compared with terrestrial microorganisms, marine microorganisms can adapt to complex environments, and their metabolites exhibit special biological activities. The use of marine beneficial bacteria can inhibit SRB activity to achieve the corrosion inhibition effect.
