  • INNOVATION POLICY AND INNOVATION MANAGEMENT

    • Innovation Marketing and Strategic Marketing

      pg(s) 37-39

      This article examines the role of innovative and strategic marketing in enhancing the competitiveness of businesses in an environment of rapid technological change. Particular attention is paid to a strategic approach to marketing planning, which involves a thorough analysis of consumer needs and market assumptions. The article emphasizes the need for continuous adaptation of product portfolios to changing market conditions and increasing fragmentation of customer segments. The concept of strategic innovation marketing is introduced as a key factor for successful product positioning, while its implementation in business strategies is considered essential for effective management of innovation processes. The final findings of the paper suggest that strategic innovation marketing not only promotes customer retention, but also enables the transformation of business models and supports the long-term growth of firms in an environment of rapidly evolving technologies.

    • Photophysical properties of some phthalocyanine derivatives using ultrafast spectroscopy

      pg(s) 40-43

      Transient absorption spectroscopy uses short laser pulses which can be up to tens of femtoseconds. These pulses can effectively “freeze” the motion of the molecules at specific times during a reaction or a dynamic process, and by modification of the time delay between the pump and probe pulses snapshots of the molecular system can be obtained at different stages of its evolution, providing insights into the underlying dynamics. For this purpose, the nanosecond or femtosecond transient absorption techniques can be utilized. In this presentation ultrafast spectroscopy (transient absorption) and emission (steady state and time-resolved fluorescence) spectroscopy were applied for to study and characterize the photophysical properties of some phthalocyanine derivatives. For this, new compounds (phthalocyanine derivatives) have been synthesized and the quantum yields and lifetimes of excited states were estimated. Also, to demonstrate excited-state processes from the transient absorption map, we obtained a ground state bleaching band (GBS), absorption in excited state (ESA) and at longer wavelength, stimulated emission (SE).

    • Effect of thermal drilling strategy on the geometrical characteristics of metal – composite joints

      pg(s) 44-47

      This paper deals with the change of joint geometry of non-ferrous metal sheets and composite plates reinforced with bi-directional glass and carbon fiber by thermal drilling due to the effect of different drilling strategy. Joints formed by direct and sequential drilling were tested. Sequential drilling represents a convenient way to minimize delamination of layered composites during joining.

    • Investigation of the local permeability of filter materials by methods with the opposite direction of local air flows

      pg(s) 48-51

      The results of investigations of local permeability of filter materials (PFM) made of powders of tin-phosphor bronze, titanium and nickel of various fractions are presented by two methods: by one method the local flow was directed to the sample from the measuring head, and by another method the local flow entered the measuring head after passing through the sample. It is established that both methods display the uniformity of the distribution of local permeability over the surface of the filter material (filtration surface) and can be used to assess the permeability of the filter material. The advantages and disadvantages of these methods are described.

    • Prototype of a Wireless MEMS-Based Sensor Node within a Wireless Sensor Network Concept

      pg(s) 52-54

      The aim of this work is to implement a wireless communication system for MEMS-based sensors within the framework of Internet of Things (IoT) applications, specifically in the context of Predictive Maintenance (PdM). The focus is placed on developing a functional prototype of a wireless sensor node that enables efficient data acquisition and transmission from commercially available MEMS vibration sensors. The solution leverages an ESP32 microcontroller for data handling and Wi-Fi communication, forming the basis of a scalable wireless sensor network (WSN). The project emphasizes their integration into a wireless system architecture suitable for industrial monitoring scenarios. This approach aims to demonstrate how low-cost MEMS sensors, when combined with IoT technologies, can contribute to accessible and modular condition monitoring solutions aligned with Industry 4.0.

    • A new type of nail for wooden structures with increased resilience

      pg(s) 55-57

      In the following work, we present the results from a research of a type of nail with a new form of section, in comparison to the round section that currently used nails have. This new form is similar to an equilateral triangle, the sides of which’ are curves [Reuleaux Triangle]. The body section of this new type of nail has three curves and three edges; his surface SR is with 5.56% larger than the surface SC of a round nail with the same section area. From the experimental research that has been made so far, it was established: (i) because of the larger compaction of the wooden material in the ends of the edges, and of the larger surface, you get a bigger friction force, resulting in a pulling-out force Fto,R that is on average twice as bigger as the pulling-out force Fto,C; (ii) because that the new form of nail has edges, this leads to bigger resistance during the rotating of the joined wooden elements one against another – the moment Mr is on average 60% bigger than the one with elements, joined with a normal nail. These advantages, as well as the use of the existing technology and machines for the production of nails without having to effect any major changes, create the conditions for the application of the new type of nail in construction, furniture production and in the everyday life, for an output of products with larger resistance to external forces. This effect will be especially useful for increasing the residential buildings’ resilience during earthquakes, hurricanes and other natural disasters.

    • Optimization of long-chain alkene synthesis from lignocellulosic wastes using photocatalysis

      pg(s) 61-64

      Tall oil fatty acid (TOFA) is a valuable byproduct derived from the processing of lignocellulosic biomass, particularly in the pulp and paper industry. In the present study, TOFA, under optimized alkaline conditions, was firstly converted to soap, then TOFA-based soap was utilized to produce long-chain alkenes using photocatalysis (photoreactor equipped with a UVA-LED lamp). In addition, the performance of TiO2, as photocatalyst, was enhanced by introducing NH4 + onto its surface. Using response surface methodology (RSM), the effect of reaction time (135, 180, and 225 min), catalyst (80, 110, and 140 mg), and TOFA-based soap quantity (50, 100, and 150 mg) were
      evaluated. The highest yield (77.7 mg) of Cn-1 long-chain alkenes was attained when ~1:1 ratio of TOFA-based soap:NH4-TiO2 was photocatalyzed at 365 nm for 180 min. The findings demonstrated that ~55% of TOFA-based soap can be converted to long chain alkenes by using photocatalysis under optimized conditions. Then, by using sulfuric acid, the alkenes were hydrated into corresponding long-chain alcohols that can serve as precursor for fabrication of bio-based extended surfactants. These findings highlighted the potential of the byproducts of lignocellulosic wastes (i.e., TOFA) as a sustainable feedstock for producing high-value chemicals

    • Simulation of solar-coal hybrid power plant based on the Rankine cycle

      pg(s) 65-68

      The use of solar energy to generate electricity in Power Plant (PP) based on the Rankine cycle is currently a strongly developed CSP system (Concentrating Solar Power) technology. Combining CSP systems with an existing Rankine cycle in coal-fired Power Plant (PP) or Combined Heat and Power Plant (CHP) can increase the maximum output of a power plant and effectively provide a transition for fossil fuel-based technologies to the use of renewable energy sources such as hybrid or renewable energy-only systems. The paper presents simulation results of a steam Rankine cycle with solar power plant components. The hybrid power system makes it possible to reduce the use of coal fuel and provide high efficiency and output power. The calculations were carried out using Ebsilon Professional software.
