A comprehensive understanding of the role of the electrocatalyst in photoelectrochemical(PEC)water splitting is central to improving its performance.Herein,taking the Si-based photoanodes(n^(+)p-Si/SiO_(x)/Fe/FeOx/MOOH,M=Fe,Co,Ni)as a model system,we investigate the effect of the transition-metal electrocatalysts on the oxygen evolution reaction(OER).Among the photoanodes with the three different electrocatalysts,the best OER activity,with a low-onset potential of∼1.01 VRHE,a high photocurrent density of 24.10 mA cm^(-2)at 1.23 VRHE,and a remarkable saturation photocurrent density of 38.82 mA cm^(-2),was obtained with the NiOOH overlayer under AM 1.5G simulated sunlight(100 mW cm^(-2))in 1 M KOH electrolyte.The optimal interfacial engineering for electrocatalysts plays a key role for achieving high performance because it promotes interfacial charge transport,provides a larger number of surface active sites,and results in higher OER activity,compared to other electrocatalysts.This study provides insights into how electrocatalysts function in water-splitting devices to guide future studies of solar energy conversion. 展开更多

A field study was conducted to investigate the effect of Aquasap, a commercially manufactured biostimulant from seaweed Kappapphycus alvarezii on some hills and foothills banana varieties namely Robusta (AAA), Njali poovan (AB), Red banana (AAA) and Nendran (AAB) by applying at 5% through foliar spray at the 3rd, 5th and 7th month of plantation. Both quantitative and quality data of fruits were analyzed along with vegetative growth of the plants. The seaweed biostimulant was found very effective on increasing the weight and nutritional contents of all four banana varieties tested. The highest yield was found in Robusta with 56.58% over control followed by Njali poovan, Red banana and Nendran with 19.08%, 39.35% and 11.46%, respectively. Yield of fruits per hectare of four varieties treated were 76.96, 19.23, 29.68 and 23.37 metric ton (mt), respectively. Fruits of treated plants also showed less moisture level as compared to control with 240.61%, 62.30%, 61.68% and 37.18% more carbohydrate, 283.71%, 94.07%, 62.87% and 38.93% higher proteins and 153.02%, 47.37%, 58.73% and 31.48% higher minerals respectively as compare to control plants. Therefore, the simple practice of application of eco-friendly seaweed based biostimulant would benefit small and marginal farmers of banana. 展开更多

Developing methods to keep the freshness of fish represents a major task of the fishery processing industry. Application of Lactic Acid Bacteria(LAB) as food preservative is a novel approach. In the present study, the possibility of using lactic acid bacteria in freshness keeping of tilapia fillets as sashimi was examined. Fish fillets were dipped in Lactobacillus plantarum 1.19(obtained from China General Microbiological Culture Collection Center) suspension as LAB-treated group. Changes in K-value, APC, sensory properties and microbial flora were analyzed. Results showed that LAB treatment slowed the increase of K-value and APC in the earlier storage, and caused a smooth decrease in sensory score. Gram-negative bacteria dominated during refrigerated storage, with Pseudomonas and Aeromonas being relatively abundant. Lactobacillus plantarum 1.19 had no obvious inhibitory effect against these Gram-negatives. However, Lactobacillus plantarum 1.19 changed the composition of Gram-positive bacteria. No Micrococcus were detected and the proportion of Staphylococcus decreased in the spoiled LAB-treated samples. The period that tilapia fillets could be used as sashimi material extended from 24 h to 48 h after LAB treatment. The potential of using LAB in sashimi processing was confirmed. 展开更多

The rare ginsenoside Compound K (C-K) is attracting more attention because of its good physiological activity and urgent need. There are many pathways to obtain ginsenoside C-K, including chemical and biological methods. Among these, the conversion of PPD-type ginsenosides by enzymatic hydrolysis is a trend due to its high efficiency and mild conditions. For effectively extracting from the other panaxadiol saponins, the conversion process for ginsenoside C-K was investigated using snailases in this study. The univariate experimental design and response surface methodology were used to determine the optimal hydrolysis conditions for the conversion of ginsenoside Rbl into ginsenoside C-K by snailases. The optimum conditions were as follows: pH 5,12, temperature 51 ℃, ratio of snailase/substrate 0.21, and reaction time 48 h. On the basis of these parameters, the addition of 1.0 mmol· L- 1 ferric ion was found to significantly improve the enzymolysis ofsnailases for the first time. With the above conditions, the maximum conversion rate reached 89.7%, suggesting that the process can obviously increase the yield of ginsenoside C-K. The bioassay tests indicated that the ginsenoside C-K showed anti-tumor activity in a series of tumor cell lines. Based on these results, we can conclude that the process of rare ginsenoside C- K production by enzymolysis with snailase is feasible, efficient, and suitable for the industrial production and application. 展开更多

Analysis of agricultural production systems of hydroponic tomato in Morelos state of Mexico, through a systematic approach, called systems development of life cycle (SDLC) was performed by comparing this with the methodology known as life cycle assessment (LCA). This permits to analyze the differences in approaches of all these methodologies to propose improvements in the current system, which can allow an improved assessment of the environmental quality of agricultural products, which often is subject to confusion. That due to measurement parameters are not generally accepted by society, producers and consumers, may ensure that the process is fully sustainable and is considered quite as a green technology processes towards an ecological benefit and therefore for the humanity. 展开更多

Due to the global expansion of irrigated areas and the limited availability of irrigation water, it is necessary to optimize water use in order to maximize crop yields under water deficit conditions. To evaluate the yield response of two processing tomato hybrids (Ercole and Genius) grown under different irrigation treatments, a field trial was conducted during the 2008 growing season in Southern Italy. Three irrigation treatments were used: the restitution of 70% of maximum evapotranspiration (ETc) both under "Deficit Irrigation" (70DI) and "Partial Root-zone Drying" (70PRD) strategies; full irrigated (FI: 100% ETc). The two water deficit irrigation treatments (DI and PRD) showed stomatal conductance values lower than FI treatment and saved a substantial amount of water maintaining reasonable marketable yield. Moreover, PRD strategy showed slightly higher "Water Use Efficiency" (WUE) values than DI. Finally, "yield response factor" (Ky) showed always values less than unity, indicating the possibility to adopt, within certain limited condition, both DI and PRD in field-grown processing tomato cultivated in Southern Italy. In conclusion, in our experimental conditions, deficit irrigation practices seem to be acceptable relatively to processing tomato yield aspects and Ky could be promoted as a useful indicator for irrigation in water deficit conditions. 展开更多

Its demand in the global market has increased in recent times. Many scholars have opined that the development of this root crop will boost rural economy especially in developing economies. This study investigates the production of cassava in Nigeria using different mechanization levels, which include: Hand Tools Technology (HTT), Draught Animal Technology (DAT) and Engine Powered Technology (EPT). These levels are classified into, low level mechanization, fair level mechanization and high level mechanization. The results show that the level of mechanization was high, only in land preparation while spraying, stem-cutting and weeding have low mechanization level. This shows that there are many unacceptable machines and suggests that efforts should be made to encourage cassava production considering the high economic, social and medical importance. 展开更多

Phospholipase is an enzyme that hydrolyzes phospholipids releasing a variety of products, like for example lyso-phospholipids, free fatty acids, di-acylglycerols, choline phosphate and phosphatidates, depending on the site of hydrolysis. In cheese production, lysophospholipids act as surface-active agents in the cheese curd, helping emulsification of water and fat during processing and reducing syneresis. Phospholipases are more specific and have little or no activity toward di- or triglycerides. As a result of phospholipid hydrolysis, flavor defects do not occur due to the main formation of palmitic, oleic, and stearic acids, which are non-volatile short chains fatty acids. According to the scientific studies the use of phospholipase is able to increase the yield of cheese and reduce the environmental impacts of cheese production. Protein and fat largely determine cheese yield. Depending on the milk composition, 75% to 78% of milk protein and 85% to 95% of milk fat are entrapped in the cheese curd. The remaining protein and fat are lost in the whey and, to a lesser extent, in the brine. Crucially in the production of pasta filata cheese fat losses occur in the hot stretching step, where the fresh curd is molded and stretched in hot water. The lysophospholipid-casein complexes should be studied to understand the mechanism leading to cheese yield improvements. 展开更多

A-64, A-56,1-62, AP-10, AP-56, AP-64 and KR-104. To understand the effect of Cl anions, HCl-impregnated sup- ports have been investigated in the dehydration reaction of glycerol at 375 ℃. For comparison, various H-zeolites were also examined. It was found that the glycerol conversion over the solid acid catalysts was strongly dependent on their acidity and surface area. And the relationship between the catalytic activity and the acidity of the catalysts was discussed. The outstanding properties of Pt/γ-Al2O3 catalyst systems for the dehydration of glycerol were revealed. Pt/γ-Al2O3 catalyst (AP-64) showed the highest catalytic activity after 50 h of reaction with an acrolein selectivity of 65% at a conversion of glycerol of 90%. Based on these results, catalysts based on γ-Al2O3 appear to be most promising for gas phase dehydration of glycerol. 展开更多
