The aim of this study was to investigate on an industrial scale the potential of multispectral imaging (MSI) in the assessment of the quality of different poultry products. Therefore, samples of chicken breast fillets, thigh fillets, marinated souvlaki and burger were subjected to MSI analysis during production together with microbiological analysis for the enumeration of Total Viable Counts (TVC) and Pseudomonas spp. Partial Least Squares Regression (PLS-R) models were developed based on the spectral data acquired to predict the “time from slaughter” parameter for each product type. Results showed that PLS-R models could predict effectively the time from slaughter in all products, while the food matrix and variations within and between batches were identified as significant factors affecting the performance of the models. The chicken thigh model showed the lowest RMSE value (0.160) and an acceptable correlation coefficient (r = 0.859), followed by the chicken burger model where RMSE and r values were 0.285 and 0.778, respectively. Additionally, for the chicken breast fillet model the calculated r and RMSE values were 0.886 and 0.383 respectively, whereas for chicken marinated souvlaki, the respective values were 0.934 and 0.348. Further improvement of the provided models is recommended in order to develop efficient models estimating time from slaughter.

“…Similar to the buried interface, the main problems to be solved for the upper interfaces of CPSCs are poor contact due to the rough surface of the perovskite and carbon electrodes, poor hole extraction and transport ability, severe surface defects resulting in non-radiative recombination at the interface, and energy-level mismatch between the layers. As a result, researchers have used organic polymers [54][55][56][57], organic salts [58][59][60][61][62][63][64][65][66], inorganic materials [67,68], and carbon nanotubes [12,69,70] for interface engineering to improve the quality of the interface, enhance the film crystallinity quality of perovskite, passivate interfacial defects, improve the interfacial energy band alignment, enhance the interfacial contact, build a hole transfer channel and act as an EBL to reduce the carrier non-radiative recombination, and accelerate the hole extraction and transfer at the interface.…”

For commercialization, further reducing the cost and increasing the stability of perovskite solar cell (PSC) have been the most essential tasks for researchers, since the efficiency of single-junction PSCs has reached a competitive level among all kinds of single-junction solar cells. Carbon-electrode-based PSCs (CPSCs), as one of the most promising constructions for achieving stable economical PSCs, now attract enormous attention. Here, we briefly review the development of CPSCs and reveal the importance of the n-i-p architecture for state-of-the-art CPSCs. Despite the promise, challenges still exist in CPSCs of n-i-p architecture, which mainly steam from the incompact contact of hole transporting layer (HTL)/carbon electrode. Thus, new carbon materials and/or novel manufactural methods should be proposed. Specifically, HTL is yet to be appropriate for state-of-the-art CPSCs since the solution process of carbon electrode may destroy the underlayer. And for further enhance the performance of CPSCs, both HTL and electron transporting layer (ETL) as well as their interfaces with perovskite active layer need to be improved. Besides, we recommend that the perovskite active layer with long carrier lifetime, strong carrier transport capability and long-term stability is of significance as well. We highlight the current researches on CPSCs and provide a systematic review of various types of regulation tools.

We have recently developed a rapid online line-scan imaging system capable of both hyperspectral Vis/NIR reflectance and fluorescence in the Vis with UV-A excitation. The hyperspectral online line-scan system was integrated with a commercial apple-sorting machine and evaluated to inspect apples for fecal contamination and defects at a processing line speed of over three apples per second. Results showed that fluorescence imaging (using a two-band ratio) could achieve detection of fecal spots on artificially contaminated apples with a 100% detection rate and no false positives regardless of the presence of defects. A NIR two-band reflectance ratio coupled with a simple classification method based on the mean intensity and homogeneity of the ratio achieved a 99.5% apple defect classification accuracy with a false positive rate of only 2%. The presented NIR processing regime overcame the presence of stem/calyx on apples that typically has been a problematic source for false positives in the detection of defects. The most significant and important outcome of this investigation is a line-scan inspection system that can potentially provide the capability for current sorting mechanisms, such as by size and color, as well as additional sorting for quality and safety attributes of food products. This line-scan based online imaging system offers great potential as a value-added dynamic inspection system due to its capability for multi-tasking to meet a variety of inspection objectives. A multi-tasking inspection system that can meet current industry sorting needs with the added benefit of safety inspection without requiring significant modification of existing infrastructure or incurring significant costs may lead the apple industry to consider adopting voluntary measures to further enhance safe production and processing of fruits.
