Organic crystals with second-order optical nonlinearity feature very high and ultra-fast nonlinearities are therefore attractive for various photonics applications. During the last decade, they have been found particularly terahertz (THz) photonics. This is mainly due to intense ultra-broadband THz-wave generation possible these crystals. We review recent progress challenges in development of organic crystalline materials detection discuss their structure, intrinsic properties, advantages...

Rapid technological innovations are changing the jobs that Science, Technology, Engineering, and Mathematics (STEM) students employed in after completing their education. Therefore, employers looking for applicants with skills beyond specialised professional competencies can be acquired chosen subjects during formal Higher education institutions (HEIs) have an important role to play this process, as they endeavour equip graduates knowledge future jobs. Our study aims identify key Slovenian...

AbstractAbstract: In last two decades, rapid development in the field of terahertz (THz) technology has opened new possibilities for creating innovative imaging and sensing systems. Although applications THz different sectors constantly increase, construction industry lags behind them. The aim this article is to review current spectroscopy research related building materials, along with key drawbacks recommendations future use. concludes that have promising potential provide many...

In this paper, we derived competences from previously developed competence models, ensuring the effective use of advanced technologies in future factories to improve sustainability their business models and strategies. Based on analysis Hogan model for leadership, compiled a selection digitalisation, automation, robotics, artificial intelligence, soft such as emotional intelligence cultural literacy. We also included required sustainability, corporate social responsibility, circular economy....

The DECIDE project entitled “Career choices competencies for the post-pandemic future using multicriteria decision-making”, aimed to empower young individuals in their career decision-making by providing them with personalised learning sources and tools monitor development of essential competencies. This paper presents findings from evaluating two key components project: an e-guide developing a web-based application that monitors individuals’ progress competency development. These help...

We consider the influence of different nanoparticles or micrometre-scale colloidal objects, which we commonly refer to as particles, on liquid crystalline (LC) orientational order in essentially spatially homogeneous particle-LC mixtures. first illustrate effects coupling a single particle with surrounding nematic molecular field. A could either act "dilution", i.e., weakly distorting local effective field, source strong distortions. In anchoring limit, particles effectively topological...

The increasing scarcity of natural resources, worsening global climate change, environmental degradation, and rising demand for food are forcing the biotechnology plastics industries to seek apply circular economy models that would lead a sustainable transition in production use bioplastics. Circular can improve economic productivity bio-based have positive impact on environment by reducing conventional plastic waste consumption petrochemical feedstocks production. In addition, some...

There is a need for fast and reliable quality authenticity control tools of pharmaceutical ingredients. Among others, hormone containing drugs foods are subject to scrutiny. In this study, terahertz (THz) spectroscopy THz imaging applied the first time analyze melatonin its product Circadin. Melatonin found naturally in human body, which responsible regulation sleep-wake cycles. frequency region between 1.5 4.5 THz, characteristic spectral features at 3.21 weaker one 4.20 observed allowing...

In the last decade, terahertz (THz) technologies have been introduced to detection, identification, and quantification of biomolecules in various biological samples. This review focuses on substances that represent important biomarkers urine associated with cancers their treatments. From a diagnostic point view, liquid biopsy is particularly because it allows non-invasive rapid collection large volumes this review, THz spectral responses considered metabolic obtained previous studies are...

A result-oriented engagement system for performance optimisation (RESPO) has been developed to systematically monitor and improve the competencies of individuals in business, lifelong learning secondary schools. The RESPO expert was transferred use higher education institutions (HEIs) based on successful practical application trials. architecture functionality original have transformed into a new format that will collect information required available educational programmes help students...

Several pharmaceutical drugs, such as alprazolam, ibuprofen, acetaminophen, activated carbon and others, caffeine-containing foods were tested using terahertz (THz) time domain spectroscopy in the range from 0.3 to 2 THz. The dry powder of drugs was mixed with HDPE pressed into pellets hydraulic press. coffee grounds also after ball-milling mixing HDPE. caffeine containing liquid dried out on paper strips various stacking. Experiments allow one determine characteristic spectral signatures...

Energy literacy is an essential prerequisite for informed and sustainable energy consumption habits. Our paper focuses on factors influencing young adults’ attitudes behaviours their knowledge of practices. The research was conducted in five European countries, Austria, Croatia, Greece, Slovenia Poland, data were collected from 219 adults between the ages twenty-nine thirty-nine. methods used are statistical analyses, including principal component analysis, a technique analysing large sets...

We study the effects of nanoparticles (NPs) on thermotropic nematic liquid crystals (LCs) in relatively dilute NP–LC mixtures. are interested fundamental generic mechanisms that quantitatively and qualitatively affect phase behavior LCs. A simple molecular field analysis shows a transition will likely occur upon entry into ordered phase. Moreover, interaction between nematogenic NPs LCs could force sergeant–soldier-like behavior, which only one component is affected despite symmetric...

We study the impact of anisotropic nanoparticles (NPs) on nematic liquid crystal (LC) order. Within a mesoscopic Flory–Huggins-type approach we have estimated regimes where LC–NP mixtures are essentially homogenous. Using lattice Lebwohl–Lasher type also studied NPs LC ordering. analysed cases orientations either frozen-in or could be varied, to which refer as random field and annealed mixtures, respectively. In latter case demonstrated existence qualitatively different regimes. particular,...
