    Synthesis of Carbon dots from Biomass Chenpi for the Detection of Hg2+

    Jun Xiang1,2,*, Xiaoqing Chen1, Qi Liu1, Huihua Jing2, Tongqiang Chen2, Wanli Tang2, Wenyang Xu2

    Journal of Renewable Materials, Vol.11, No.10, pp. 3739-3750, 2023, DOI:10.32604/jrm.2023.028090

    Abstract Biomass-derived carbon dots (C-dots) are considered a very important carbon material in metal ion detection of their small environmental impact, simple preparation process, and relatively low cost. A green approach for synthesizing biomass-derived C-dots from Chenpi using a hydrothermal method without further processing is proposed in the present study. The as-synthesized C-dots show excellent fluorescence properties, superior resistance to UV irradiation photobleaching, and high photostability in salt-containing solutions. The C-dots were used in the form of label-free fluorescent probes for sensitively detecting Hg2+ selectively. The outcome relationship behaved linearly and was established based on a given range between 10–300 nM… More > Graphic Abstract

    Abstract Secondary lignocellulosic biomass has proved to be useful as an energy source through its oxidation by means of combustion processes. In accordance with the above, in this paper, we wanted to study the ash from urban pruning residues that are generated in cities in the Neotropics. Species such as Licania tomentosa, Azadirachta indica, Ficus benjamina, Terminalia catappa, Leucaena leucocephala, Prosopis juliflora and Pithecellobium dulce were selected because they have been previously studied and showed potential for thermal energy generation. These materials were calcined in an oxidizing atmosphere and characterized by X-ray diffraction and fluorescence, scanning electron microscopy with microchemistry, BET… More > Graphic Abstract

    Erdiwansyah Erdiwansyaha,e,f, Mahidin Mahidinb,*, Husni Husinb, Nasaruddin Nasaruddinc, Asri Ganib, Muhammad Faisal, Muhtadin Muhtadind, Muhammad Zakib, Rizalman Mamate

    Frontiers in Heat and Mass Transfer, Vol.20, pp. 1-9, 2023, DOI:10.5098/hmt.20.29

    Abstract The conversion of solid biomass waste into energy continues to be developed at this time to reduce dependence on fossil energy. Energy conversion can be carried out using several technologies commercialized by several industries, including the fluidized-bed combustor (FBC). This FBC technology has also been developed in several ways, such as the modification or unique modelling. In particular, the perforated plate modelling applied in this study is to provide excess air supply so that complete combustion can be achieved. In addition, modifying the perforated plate increases efficiency and radiation and reduces heat loss in the FBC combustion chamber. This research… More >

    Abstract The development and utilization of biomass and agroforestry processing byproducts for high-value applications have been an important topic in the field of renewable materials research. Based on this, a two-step microwave hydrothermal pre-carbonization and KOH activation method was proposed to synthesize tannin-based activated carbons with a high specific surface area, hierarchical pore structure, and good electrochemical performance. The microstructure, texture properties, and physicochemical characteristics were investigated. The results show that the prepared tannin-based activated carbons presented a hierarchical pore structure (micro- and mesopores) with a specific surface area as high as 997.46 m3 g−1 . The electrochemical analysis shows that… More > Graphic Abstract

    Phyton-International Journal of Experimental Botany, Vol.92, No.5, pp. 1439-1467, 2023, DOI:10.32604/phyton.2023.023076

    Abstract Miscanthus, is a promising bioenergy crop, considered superior to other bioenergy crops because of its higher water and nutrient use efficiency, cold tolerance, and higher production of biomass. Broadleaf weeds and grass weeds, cause major problems in the Miscanthus field. A field experiment was conducted in 2018 and 2019, to assess the effects of pre-emergence (alachlor and napropamide) and post-emergence herbicides (nicosulfuron, dicamba, bentazon, and glufosinate ammonium) on broadleaf and grass weeds in M. sinensis and M. sacchariflorus fields. The weed control efficiency and phytotoxicity of pre- and post-emergence herbicides were evaluated at 30 days after treatment (DAT) and compared… More >

    Journal of Renewable Materials, Vol.11, No.4, pp. 1661-1686, 2023, DOI:10.32604/jrm.2023.023669

    Abstract Tung oil (TO)/ultraviolet (UV) photo-composite curing material possesses the characteristics of low curing temperature, low material shrinkage and low environmental pollution. Accordingly, this material must be developed and utilized with the conjugated double bonds contained in the long chain of the main structure (α-tung acid) molecules in the refined TO. The aforementioned material can be chemically modified using a variety of chemical methods to develop a new TO-based UV photocurable material due to its unique chemical properties. This work reviews the research progress of TO/UV photo-composite curing materials in recent years. Firstly, the chemical structure and application of TO and… More >

    Najeh Ghilen1,3,*, Mohammed El Ganaoui3, Slimane Gabsi1,2, Riad Benelmir3

    FDMP-Fluid Dynamics & Materials Processing, Vol.19, No.4, pp. 1015-1026, 2023, DOI:10.32604/fdmp.2022.022285

    Abstract A dynamic model is presented for a chiller working with a composite adsorbent (silica activated carbon/CaCl2)–water pair in a solar-biomass cooling installation. The main objective is determining a link between two possible evaporator configurations and the refrigerator’s performances. The two considered evaporators work at different pressure levels. The related time evolution profiles of temperature, pressure and water content are studied. Moreover, the effects of hot water inlet temperature and cooling water inlet temperature on the specific cooling capacity (SCP) and coefficient of performance (COP) are predicted by means of numerical simulations. The results show that an increase in the temperature… More >

    Jeltzlin Semerel1, Nigel John1, Wim Dehaen2, Pedro Fardim3,*

    Journal of Renewable Materials, Vol.11, No.3, pp. 1031-1061, 2023, DOI:10.32604/jrm.2022.023449

    Abstract Aloe vera plant is known worldwide for its medicinal properties and application in gel-based products such as shampoo, soap, and sunscreen. However, the demand for these gel-based products has led to a surplus production of Aloe vera processing waste. An Aloe vera gel processing facility could generate up to 4000 kg of Aloe vera waste per month. Currently the Aloe vera waste is being disposed to the landfill or used as fertilizer. A sustainable management system for the Aloe vera processing waste should be considered, due to the negative societal and environmental impacts of the currents waste disposal methods. Therefore,… More > Graphic Abstract
