COCO, a process simulator: methane oxidation simulation & its agreement with commercial simulator’s predictions

Abstract It is impossible to overstate the value of process simulators in teaching process engineers about petrochemical, chemical, nuclear, and biological processes. Several chemical engineering topics, including process design, thermodynamics, process integration, separation processes, safety, and others, are made easier to teach because of this. Only a handful of these process simulators are freeware, while most are largely commercial. The ones that are commercialized are renowned for their friendliness, extensive media coverage, and international credibility attained for their forecasts in several industrial applications. However, schools in low-income countries may not be able to buy them. In contrast, the freeware publicity is not relatively low, less friendly, and cheaper than the commercial ones. This research compares the agreement of the forecast of commercial process simulators with freeware ones in an effort to strengthen institutions’ trust in the prediction of freeware process simulators. The analysis modeled and simulated a chemical process involving the Gibbs reactor, heater, compressor, and mixer in the COCO and Aspen HYSYS simulators. Findings from the research reveal good agreement in the predicted results obtained from the various process simulators. With the use of COCO, different possible methane oxidation routes were analyzed. The analysis confirmed that the route leading to the formation of CO2 and water would be less energetic than other routes. In addition, the formation of water would be much easier in the process than hydrogen at the condition employed in the study. Due to cost, the study recommends using the freeware process simulator instead of the cracked version, which is often utilized in educating process engineers and research projects in communities where research and education are poorly funded.

Wilder than intense: higher frequency, variability, and viral flows of porcine circovirus 3 in wild boars and rural farms compared to intensive ones in northern Italy.

Porcine circovirus 3 (PCV-3) was firstly reported in 2017. Although evidence of its pathogenic role has been provided, its clinical relevance seems lower than Porcine circovirus 2 (PCV-2), as well as its evolutionary rate. Different studies have reported a high PCV-3 prevalence in wild boars, sometimes higher than the one observed in commercial pigs. Nevertheless, to date, few studies have objectively investigated the relationships between these populations when inhabiting the same area. Moreover, the role of small-scale, backyard pig production in PCV-3 epidemiology is still obscure. The present study investigated PCV-3 occurrence in 216 samples collected from the same area of Northern Italy from commercial and rural pigs, and wild boars. PCV-3 presence was tested by qPCR and complete genome or ORF2 sequences were obtained when possible and analysed using a combination of statistical, phylogenetic and phylodynamic approaches. A higher infection risk in wild boars and rural pigs compared to the commercial ones was demonstrated. The phylodynamic analysis confirmed a larger viral population size in wild and rural populations and estimated a preferential viral flow from these populations to commercial pigs. A significant flow from wild to rural animals was also proven. The analysis of the Italian sequences and the comparison with a broader international reference dataset highlighted the circulation of a highly divergent clade in Italian rural pigs and wild boars only. Overall, the present study results demonstrate the role of non-commercial pig populations in PCV-3 maintenance, epidemiology and evolution, which could represent a threat to intensive farming.

Industrial washing conditions as factor that influence the cellulose structure and mechanical strength of bed linens

It is crucial for companies providing rental and maintenance services to hotels and hospitals to tackle the problem of decreased physical longevity caused by frequent laundering procedures in the industrial textile sector. Proper maintenance of bed linens is vital as they undergo multiple rigorous preservation techniques, such as being treated with chlorine to remove tough stains and sanitize the fabrics. The mechanical strength of fabric made of 100% cotton fibre products greatly relies on the degree of polymerization of cellulose-cotton fibre material. The study evaluated the washing performance of five cotton fabrics. Two weaving pattern variations were used and the fabrics were composed either of 100% cotton or a blend of 50% cotton and 50% polyester fibres. The washing methods included commercial and chlorine-based laboratory washing. 100% cotton fabrics, especially in plain weave show higher tensile strength falls then blended ones. The pure cotton fabric loss much more of its initial strength after only few chlorine-based washings than after hundred commercial ones. Limiting viscosity number values drop in half after hundred commercial washings for cotton fibres taken from tested woven fabrics. In comparison, decline of this parameter after only ten chlorine-based washings is more than 80% of their initial values. Performing the maintenance process without free chlorine, while still retaining its high effectiveness, can notably augment the frequency of maintenance procedures and preserve the mechanical durability of cotton fabrics over a longer time span. This leads to a reduction in textile waste residues.

Straight Manipulation Annealing in a Solvent Atmosphere for Quality-Improved Cs2AgBiBr6 Perovskites.

As a new-generation photoelectric material, perovskites have attracted researchers' attention due to their excellent optoelectronic properties. However, the existence of defects inevitably causes structural degradation and restricts their performance, which need to be further improved by post-treatment. At present, post-treatments mostly focus on non-contact treatments, which may constrain the effect since the influence on the perovskites caused by the direct contact is much more straightly. Therefore, we proposed an annealing strategy of straight manipulation in a solvent atmosphere with the assistance of polyimide (PI) tape for the perovskite post-treatment, due to the high heat resistance and less glue residual of this tape. It casts an influence on the perovskite directly, proving the possibility of the straight manipulation by operators, promoting the recrystallization of the perovskite grains and removing the impurity substance. The optimized Pb-free perovskite film exhibits a better X-ray sensitivity of 7.5 × 104 μC Gyair-1 cm-2 and a great detection limit of 47 nGyair s-1, which is comparable to advanced Pb-based perovskite X-ray detectors and all commercial ones. The new annealing strategy provides a facile, effective, and simple method to improve the perovskite quality, exhibiting the potential and harmlessness of the direct contact post-treatment, which paves the way for a broader application of perovskites.

Curricular and Extracurricular Entrepreneurial Activities Supporting Entrepreneurial Self-Efficacy and Desirability of Rural Youth

Entrepreneurship may be the only viable solution for finding employment in rural areas because of their limited labor markets. However, how curricular and extracurricular entrepreneurial activities can support the entrepreneurial potential of rural youth remains a question. Using a mixed-methods approach, we investigate the impact of curricular and extracurricular entrepreneurial activities on rural adolescents’ entrepreneurial self-efficacy (ESE) and desirability. Our findings show that extracurricular entrepreneurial activities, especially inventive and commercial ones, enhance both ESE and entrepreneurial desirability, but formal curricular entrepreneurial activities do not. Our study highlights how extracurricular entrepreneurial activities can support young people’s perceptions of their entrepreneurial potential while allowing them to explore and exploit local entrepreneurial opportunities. These activities are vital for rural areas to enable rural youth to see opportunities in their local surroundings and consider entrepreneurship as a career option early in life. The implications suggest that rural entrepreneurship education could leverage naturally occurring opportunities for leisure-time entrepreneurial activities in rural areas.

Artificial Neural Network in the Development of Halal Cosmetic Formulation Containing Okara

The development of halal cosmetic formulations presents a challenge to obtain optimised formulations with desirable qualities as it involves many ingredients. The advancement of cosmetic technologies employs multivariate statistical techniques such as artificial neural networks (ANN) to optimise cosmetic formulation, which aims to overcome the shortcomings of traditional formulation methods, which are laborious and cumbersome. Okara is a by-product of the production of soy-based products. Okara has been found to have numerous benefits for many industries and has been discovered as a promising halal cosmetic ingredient. Okara is a plant-derived ingredient; it can be incorporated as a cosmetic ingredient if essential aspects of production are addressed, such as using permissible substances, manufacturing, storage, packaging, and delivery following Shariah requirements. This study aims to develop an optimised halal cosmetic soap formulation containing okara using ANN to achieve the desired hardness of the soap. The influential input variables were the main compositions of the okara soap formulations, containing different fatty acids and oils, and okara through a saponification process. In contrast, the hardness (N) of the soap was the response used as the output. Five different algorithms trained ANN. Generic Algorithm (GA) 6-09-1 was selected as the final optimum model to optimise the halal cosmetic soap formulation. GA modelling was further validated, and the experimentally obtained actual hardness (N) value was close to the predicted value. In conclusion, they were optimised formulating using ANN to produce a soap with desirable properties better than those of commercial ones.

Influence of Native Saccharomyces cerevisiae Strains on Malvasia aromatica Wines.

In the search of tools to deal with climate change-related effects along with the aim of avoiding the loss of aromatic typicity in wine, two native yeasts strains of Saccharomyces cerevisiae (CLI 271 and CLI 889) were evaluated to determine their influence on white Malvasia aromatica wines aroma composition and sensory characteristics. The strains were tested versus a commercial yeast strain (LSA). The fermentations were performed on grape must of the Malvasia aromatica variety previously macerated. Wine quality was studied by analysis of oenological parameters together with volatile aroma components using gas chromatography coupled to flame ionization detector (GC-FID) to quantify major volatiles compounds and headspace-solid phase microextraction coupled with gas chromatography-mass spectrometry (HS-SPME/GC-MS) to determine terpenoids and C13-norisoprenoids. Sensorial analysis was also realized by an experienced taster panel. Wines from locally-selected yeasts strains used had lower volatile acidity levels and higher concentration of aromatic compounds compared to the commercial strain ones. The yeast strain S. cerevisiae CLI 271 provided wines with a higher concentration of esters related to fruity attributes, especially isoamyl acetate. The tasting panel highlighted the strong floral character of wines from S. cerevisiae CLI 889 fermentation. The use of microorganisms well adapted to climatic conditions can be used to produce quality wines of the Malvasia aromatica variety.

Method for Benchmarking Li Metal Anodes: A Mandatory Step toward Reliable Lithium Metal Batteries

All-solid-state batteries are known to be the new energy storage holy grail that will lead to safer batteries with higher energy density than current Li-ion batteries. The use of a solid electrolyte enables the use of lithium metal as the anode material. However, its composition, its thickness, and the quality/nature of its passivation layer can strongly affect the performance of the battery. For this reason, we propose a simple benchmarking method that evaluates and compares the quality and electrochemical performance of various Li anodes. This method can be easily reproduced, especially concerning the electrochemical evaluation that uses a commercial liquid electrolyte and the widely spread coin-cell format. In total, ~285 coin cells were assembled to benchmark our in-house lithium metal foil (Lithium HQ) with two commercial ones and the results showed the superior performance of our Li metal anode. The performance of the cells seems closely related to the quality and uniformity of the Li surface. In addition, we propose including in the benchmarking method the effect of Li aging in a dry room on the electrochemical performance. This effect is important to consider because the fabrication of all-solid-state batteries is conducted in such an environment.

Geo Аssets Engineering, 2023, vol. 334, no. 6, рр.120-125. In Rus. Relevance. Hydraulic fracturing in production and injection wells is one of the effective method for enhancing oil recovery, involving low-permeability zones and interlayers in the development, a mechanism for a wider coverage of productive zones by waterflooding, which makes it possible to convert part of off-balance reserves into commercial ones. According to experts, the use of hydraulic fracturing can increase the oil and gas recovery factor by 10–15 %. Currently, most of the oil fields in the Perm Territory are at the final stage of development. These fields, as a rule, are characterized by non-draining zones with residual reserves and low well flow rates. Most of the remaining reserves of the fields are concentrated in low-permeability reservoirs with a high degree of heterogeneity and difficult fluid filtration. The increase in the productivity of wells of these production facilities is achieved through the use of various geological and technical measures. The main aim: to develop a methodology for predicting the oil production rate post-frac with parameters that influence more, taking into account geological and technological characteristics of the object. Objects: Kashirskiy and Podolskiy carbonate deposits on one of the Permian fields. Methods: correlation and regression analysis. Results. The hydraulic fracturing method is widely used to increase well productivity. Unfortunately, oil flow rates obtained in practice do not always correspond to preliminary calculations. Using the example of one of the fields in the Perm Territory, a method proposed that allows estimating the initial oil production rate after hydraulic fracturing using the values of the technological parameters of productive deposits and the methods of mathematical statistics. A good agreement between model and experimental results was obtained.

Filamentation‐Induced Volume Plasma Grating: Dynamics, Possibilities, and Advantages

AbstractStable propagation of laser filamentation arrays paves new ways for cross‐scale manufacturing. Although a single filament or multiple filaments can be used for laser processing in transparent media, sustainable developments of higher throughput and lower energy consumption are always the pursuit. Here, a proof‐of‐concept approach is proposed in which cross‐scale manufacturing of 3D microstructures is realized via an ionization‐induced volume plasma grating. The volume plasma grating is generated by the noncollinear interaction of two batches of arrays of multiple filaments. The volume plasma grating cannot only regulate the distribution of multiple filamentation but also promote the intensity inside the filaments. By this approach, 3D microstructures are written by 1D sample translation. In addition, rapid fabrications of volume gratings and terahertz wire grid polarizers (THz WGPs) are demonstrated by laser modification using volume plasma grating. The characteristics of the fabricated THz WGPs are comparable to those of commercial ones. The limitations and future implementations of this approach are discussed.

Dry cured low-fat rabbit sausage: A much healthier disruptive food that enhances rabbit meat consumption

The main objective of this research was to develop a fuet from rabbit meat with reduced fat and salt content to encourage rabbit consumption and to find out consumer preference for this innovative food compared to retail fuet. Two products were designed: F5, containing fat and F4, where fatty tissue was substituted by konjac gum. In both, salt was partially substituted by KCl. These products, in comparison to commercial ones (pork, chicken and turkey), showed a reduction of at least 40% in the total energy value while protein raised on average 57.81% because of the lower fat content of rabbit and konjac gum use. In addition, there was a decrease in the salt content of approximately 19.50%. The above represents a huge competitive advantage for these new products from a nutritional point of view. The rabbit fuets were characterised by a spicy taste, slightly sour smell, and succulence, lower than in commercial fuets. It could be concluded that the rabbit fuet had a higher protein and lower fat and salt content than commercial fuets. However, they were less juicy and less succulent and therefore consumers preferred the commercial ones. The use of konjac gum does not seem to have any effect on this type of cured product.

An Evaluation of Legislative Frameworks and Structures for Policing Stock Theft in South Africa

South Africa has been plagued by rising incidences of stock theft for decades. However, it is now evolving and perpetrated by organised syndicates rather than only petty thieves, the continuous demands for livestock aid to the manifestation of this crime. Therefore, the objective of this study was to evaluate current legislative frameworks and available structures for policing stock theft in South African rural communities. This qualitative study adopted the non-empirical research design: Systematic review, supported by the evaluative research objective, while closely looking at recent South African reputable reports on this subject, restricted from 2000-2021 (Not in sequence) for data collections. The inductive Thematic Content Analysis (TCA) was employed for data analysis. The persistent nature of this problem poses serious threats to food security and livelihood development for the rural livestock farmers, as well as the commercial ones. It was clear that the legislative frameworks and structures for policing stock theft in South African rural communities are of the utmost importance to curb this crime. However, from a number of reported stock theft cases, the effectiveness of legislations and standing structures is highly questioned. Therefore, successful sustainable stock theft prevention strategies should consists of close and concerted partnership-based collaborations, interactions and information exchanges, based on enhancing legislative frameworks. This can offer additions, amendments, corrections, incorporating and re-drafting of ‘new sections’ of the existing Acts to improve their deterrent efforts.

Organic filler-free synthesis of mordenite molecular sieves using industrial residues

Considering the complex elemental and phase compositions, it is a challenge to realize the high value utilization of solid residues in the preparation unit of fluid catalytic cracking catalysts (i.e., FCCR). The current research proposes a disposal approach of FCCR by a direct transformation from FCCR to mordenite molecular sieves. Species evaluation of FCCR in alkaline fusion activation is investigated. Ageing temperature/ duration, crystalline temperature/ duration, amount of water and silica sol are systematically optimized. Obtained mordenite molecular sieves are pure and highly crystallized. When employed as catalysts for the isomerization of α-pinene, as-synthesized mordenite molecular sieves have a comparable performance with commercial ones due to the low diffusion resistance of hierarchical pore structure. These researches are important as a reference for the utilization of FCCR in the field of zeolitic synthesis.

ТИПОГРАФІКА СЛОГАНІВ У КОМЕРЦІЙНІЙ РЕКЛАМІ НА ТЕРЕНАХ УКРАЇНИ

Factual and analytical materials on the typography of slogans in commercial advertising in Ukraine in the 2020s have been introduced into scientific circulation. The topic is relevant, because advertising is the engine of modern trade in the field of production of goods and provision of services, and the development of a successful advertising slogan is a basic need for the development of the brand of any enterprise. However, despite the rapid development of graphic design in Ukraine, today there is a small amount of scientific research in the field of typography of fonts in the development of slogans in commercial advertising. In particular, in the scientific literature, there are still no recommendations for the development of the typography of slogans in advertising, in particular, commercial ones. Therefore, the purpose of this publication is to highlight theoretical materials that will fill this gap. The features of typography as a tool for solving functional and aesthetic aspects in the design of advertising products are analyzed. On the basis of research, the influence of advertising slogans was evaluated, the use of different font models was considered. Based on the obtained data, as a result, the most frequently used and visually expressive methods, which are practiced in the typography of slogans on the territory of Ukraine, were brought out. It was found that the majority of respondents: pay attention to commercial advertising, however, they are neutral to any advertising tool and buy a product, relying only on their own assessment of its quality, therefore, they are rarely influenced by advertising. At the same time, 95% of respondents know what a slogan is and believe that unconsciously some of the advertising slogans influenced the purchase of the product. The majority of respondents pay attention to the writing of texts and, in particular, to the fonts themselves, however, less than half of the respondents pay attention to the typography of slogans, while most of the respondents agree with the statement that correctly selected fonts in commercial advertising slogans influence the mood of consumers. It was established that the majority of respondents preferred: a combination of both components in commercial advertising: a successful font composition of the slogan, and an interesting visual series; placement of the font composition of the slogan at the top in the middle, because, in their opinion, such a compositional solution attracts the most attention; placement of the slogan to the right of the logo, as it is easier to read the first time; harmonious combination of content and stylization of the font; fonts in the style of Old Slavic typefaces and know what the «Ruthenia» font of V. Chebanyk looks like; medium-weight fonts; laconic letters without serifs and unnecessary elements; fonts without serifs, of the same thickness; letters with a strong slant, which are close to handwritten drawing; classic font with Times New Roman serifs; fonts of neutral color, black and white, with gradations of gray; font composition of white color on a red background.

Stepping toward Portable Optoelectronics with SnO2 Quantum Dot-Based Electron Transport Layers.

With a power conversion efficiency (PCE) of more than 25%, perovskite solar cells (PSCs) have shown an immense potential application for solar energy conversion. Owing to lower manufacturing costs and facile processibility via printing techniques, PSCs can easily be scaled up to an industrial scale. The device performance of printed PSCs has been improving steadily with the development and optimization of the printing process for the device functional layers. Various kinds of SnO2 nanoparticle (NP) dispersion solutions including commercial ones are used to print the electron transport layer (ETL) of printed PSCs, and high processing temperatures are often required to obtain ETLs with optimum quality. This, however, limits the application of SnO2 ETLs in printed and flexible PSCs. In this work, the use of an alternative SnO2 dispersion solution based on SnO2 quantum dots (QDs) to fabricate ETLs of printed PSCs on flexible substrates is reported. A comparative analysis of the performance and properties of the obtained devices with the devices fabricated employing ETLs made with a commercial SnO2 NP dispersion solution is carried out. The ETLs made with SnO2 QDs are shown to improve the performance of devices by ∼11% on average compared to the ETLs made with SnO2 NPs. It is found that employing SnO2 QDs can reduce trap states in the perovskite layer and improve charge extraction in devices.

Investigating the performance of bio-based demulsifiers for the demulsification of Nigerian crude oils

Commercial demulsifiers used by Nigerian National Petroleum Corporation (NNPC) are not biodegradable, making it paramount to seek bio-demulsifiers that can be produced in Nigeria from Nigerian vegetable seed oils. In this study, three demulsifiers were produced from Nigerian vegetable seed oils namely; Neem seeds, Mahogany seeds and Calabash seeds in concentrations ranging from 0.5-2.5 mL/10 mL of emulsion. These demulsifiers were tested under the same condition as the common commercial ones used in NNPC for static, dynamic, thermal and basic sediment and water removal. They all performed very well except for the dynamic test, which had low performance. The calabash demulsifier had a high performance of 80% same as the commercial on static test followed by Neem with 75%. The dynamic test recorded low results with the Neem demulsifier at 45% as the highest among the bio-demulsifiers and the commercial demulsifier recorded at 78%. On thermal tests, Calabash tied with commercial demulsifier at 80% followed by Neem demulsifier with 75%. In the basic sediment and water test, the Neem demulsifier had 75% while the commercial had 78%. They are, therefore, good enough to replace commercial demulsifiers.

Simulation study on dynamic characteristics of SiC MOSFET

In this paper, the third generation power MOSFET is introduced, and the physical model based on silicon based MOSFET is improved for SiC MOSFET, and the commercial planar gate and trench gate 1.2kV SiC MOSFET are simulated. The accuracy of physical modals is tested by comparing the static characteristics with commercial ones. The dynamic characteristics of two MOSFETs are simulated by inductively clamped double pulse circuit, and the circuit parameters are analyzed according to the static characteristics of the devices. The switching loss of the two MOSFETs is calculated and compared by using TCAD software. In the two devices with the same volume, the trench gate structure has the larger switching loss.

Wearable graphene-based fabric electrodes for enhanced and long-term biosignal detection

Wearable health sensing devices are crucial and the development of multi-sensing textiles for non-invasive and continuous long-term biosignal monitoring is of primary interest. Nowadays, different wearable sensors are available but they usually lack comfort for continuous use during normal daily life activities. In this study, new graphene-based flexible dry electrodes are investigated to overcome the limitations of the currently available electrodes. Briefly, they are realized through casting PVDF (polyvinylidene fluoride)/GNP (graphene nanoplatelets) nanocomposite over commercial textiles. These electrodes are soft and flexible and adhere more easily to the skin. In terms of performance, the PVDF/GNP electrodes show lower impedance per unit area compared to commercial ones, hence they can be employed for biosignal detection. In particular, the developed electrodes are used for electrocardiogram (ECG) signal monitoring. The recorded ECG signal-to-noise ratio (SNR) reached up to 40 dB and all necessary ECG signal features and intervals are clearly distinguishable. Furthermore, the essential ECG signal intervals on each cadiac cycle show very small variations in time. Finally, the superhydrophobic property allows the electrodes to be used repeatedly after washing. As a final note, the developed dry PVDF/GNP electrodes provide reusability, biocompatibility, good skin-electrode contact, and no signs of skin irritation.

Cutting ability and durability of surgical blade fabricated from biocompatible Zr-based bulk metallic glass

ABSTRACT A biocompatible Zr54Al17Co29 bulk metallic glass (BMG) becomes a potential candidate for medical device materials due to its excellent properties; however, the effort to investigate the material performance in medical devices has never been attempted. Surgical blades were developed from Zr54Al17Co29 BMG composition using different sizes of plates to address the microstructural variation. Their cutting abilities were investigated using a designed indentation-cutting rig for sharpness tests and compared to commercial carbon steel (CS) blades. While the fully amorphous structure was confirmed in a 2 mm BMG, the presence of nanocrystal phases was implied in the 3 mm BMG. The BMG blades showed extremely higher cutting-edge quality compared to the commercial ones. In addition, the sharpness improvement was shown in 2- and 3-mm BMG blades with the blade sharpness index (BSI) of 0.29 and 0.34 compared to commercial blade BSI of 0.37. The BMG blades also showed good durability indicated by the higher edge resistance from deformation. These phenomena were determined by the absence of grain boundary and dislocation of BMG thus performing a higher elastic strain than the crystalline material to avoid plastic deformation on the extremely small cross-sectional area of the cutting edge during substrate incision.

Green Technologies for Persimmon By-Products Revalorisation as Sustainable Sources of Dietary Fibre and Antioxidants for Functional Beverages Development.

The use of green technologies such as ultrasound and natural deep eutectic solvents (NADES) for revalorisation of food and agricultural by-products represents a sustainable way to tackle waste and promote a healthier environment while delivering much-needed functional food ingredients for an increasingly unhealthy population. The processing of persimmon (Diospyros kaki Thunb.) generates large amounts of by-products rich in fibre-bound bioactive phytochemicals. This paper assessed the extractability of bioactive compounds through NADES and the functional properties of the persimmon polysaccharide-rich by-products to evaluate their suitability to be used as functional ingredients in commercial beverages. Although higher amounts of carotenoids and polyphenols were extracted after eutectic treatment vs. conventional extraction (p < 0.05), the fibre-bound bioactives remained abundant (p < 0.001) in the resulting persimmon pulp by-product (PPBP) and persimmon pulp dietary fibre (PPDF), showing also a strong antioxidant activity (DPPH•, ABTS•+ assays) and an improved digestibility and fibre fermentability. The main structural components of PPBP and PPDF are cellulose, hemicellulose and pectin. PPDF-added dairy-based drink showed more than 50% of preference over the control among panellists and similar acceptability scores to the commercial ones. Persimmon pulp by-products represent sustainable source of dietary fibre and bioactives and are suitable candidates to develop functional ingredients for food industry applications.
