This abundant organic material is found throughout the world. Due to its recalcitrant nature, lignocellulose poses a challenge for efficient conversion into biofuels, biochemicals, and other valuable products. Myco degradation, which involves the use of fungi to degrade lignocellulosic materials, offers a sustainable and cost-efficient resolution to this challenge. This review provides an overview of the mechanisms and applications of myco degradation for lignocellulosic biomass degradation. The review discusses the various types of fungi involved in lignocellulose degradation, their enzymatic systems, and the factors that influences their performance. Furthermore, the potential applications of myco degradation products, such as biofuels, enzymes, and bioplastics, are reviewed. It also highlights the implications of myco degradation for waste management and sustainable development. Overall, myco degradation represents a promising technology for the efficient deprivation of lignocellulosic waste biomass, and further research in this field holds great potential for the sustainable creation of bio-based products.","PeriodicalId":100109,"journal":{"name":"Applied Research","volume":"3 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/appl.202300119","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139781816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, they also serve as a nutrient-rich delicacy in many African and Arabic communities where they are traditionally harvested for food and feed. Traditional harvesting methods are inefficient, laborious, and time-consuming; hence, there is a need to explore more convenient and efficient techniques. This study assessed preferential selection and feeding behavior of desert locusts to identify trap plants that could attract and aggregate them for easy harvesting. Four trap plants (cowpea, finger millet, sorghum, and amaranth) and four repellent plants (neem, pencil cactus, garlic, and cayenne red pepper) were evaluated through multiple-choice experiments. A randomized complete block design involving mature adult, immature adult, and hopper stages of desert locusts was used. Analysis of variance was used to determine the effects of repellent and trap plants on feeding preferences of desert locusts. Mean differences between treatments at p < 0.05 were separated using post hoc Tukey's honestly significant difference. Cowpea as the most preferred trap plant attracted 62.7%, 70.7%, and 76.9% of mature adult, immature adult, and hopper locust stages, respectively. Neem exhibited the most potent repellent effect and attracted no desert locusts for feeding. Neem repelled locusts, thereby reducing infestation and damage of cowpea as a pull plant when both plants were grown in the same pot in a “push–pull” system. The push–pull attracted 3.7%, 24.3%, and 7.8% of mature adult, immature adult, and hopper locust stages, respectively. However, cowpea attracted large numbers of locusts (96.3% mature adults, 75.7% immature adults, and 92.2% hoppers) when grown separately from neem. These findings provide valuable insights on the potential of exploiting traps and repellents to enhance aggregation and harvesting of desert locusts as food and feed.","PeriodicalId":100109,"journal":{"name":"Applied Research","volume":"3 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/appl.202300108","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139796533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Under the selected instrument operating conditions, all the residual solvents were completely separated. A detailed analysis was conducted on these 11 organic solvents. The mass concentrations of these solvents were linearly correlated with the chromatographic peak area, with a linear R2 is called determination coefficient R2 ≥ 0.99, and the relative standard deviation (n = 5) was less than 5.8%. The recovery rates of n-hexane and toluene were 90.3% and 102.9%, respectively.

This research focuses on the examination of a dental implant sample fabricated using the SLM method. The investigation encompasses multiple aspects, including hardness, dimensional accuracy, strength, and surface properties. The results demonstrate that the hardness of the SLM sample is comparable to that of machined samples, establishing it as a viable alternative to traditional production methods. Dimensional tests reveal that the SLM sample adheres to the required acceptance limits for critical dimensions. The strength of the sample, with a value of 700 MPa, proves to be acceptable for medical applications. The presence of surface porosity and holes in the SLM sample highlights its potential for enhanced bone ossification. However, challenges associated with thread construction in the SLM process require further attention.

Polydimethylsiloxane (PDMS) is widely employed in microchannel fabrication due to its affordability, biocompatibility, and straightforward fabrication process. However, PDMS's low surface energy poses challenges in bonding with many organic and inorganic substrates, hindering the development of hybrid microfluidic devices. In this study, a simple and versatile three step process is presented for bonding PDMS microchannels with organic (cyclic olefin copolymer (COC)) and inorganic substrates (lithium niobate (LiNbO3)) using plasma activation and a silane coupling agent. Initially, the PDMS surface undergoes oxygen/argon plasma activation, followed by functionalization with (3-aminopropyl) triethoxysilane (APTES). Subsequently, the COC or LiNbO3 is plasma activated and brought into contact with PDMS under a load at a specific temperature. Characterization by Fourier transform infrared, scanning electron microscopy, atomic force microscopy, and contact angle measurements confirmed the successful treatment of the substrates. In addition, bonding strength of the fabricated hybrid devices was assessed through leakage and tensile tests. Under optimized conditions (100°C and 4% v/v APTES), PDMS-COC hybrid microchannels achieved a flow rate of 600 mL/h without leakage and a tensile strength of 562 kPa. Conversely, the PDMS- LiNbO3 assembly demonstrated a flow rate of 216 mL/h before leakage, with a tensile strength of 334 kPa. This bonding method exhibits significant potential and versatility for various materials in microfluidic applications, ranging from biomedical research to enhanced oil recovery.","PeriodicalId":100109,"journal":{"name":"Applied Research","volume":"3 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/appl.202300116","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139598617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
