The careless dumping of agricultural waste in Nigeria is a significant environmental issue that requires attention. Some states haphazardly dump the pod Parkia biglobosa, should have served an essential purpose to wealth context. study investigates synthesis and characterization nanocellulose derived from biglobosa pod. Standard procedures were used isolate characterised with FTIR, SEM-EDX, XRD, TGA, DTG techniques. FTIR analysis identified existence O-H, C-O-C pyranose rings, cellulose ?-glycosidic connections. SEM showed surface was uneven had small clusters NCC. devolatilization raw NCC ALBP recorded at 43.205% 71.90%, respectively, exhibiting highest value. At 380?C 400?C, thermal decomposition peaks for caused most weight loss. Nanocrystal has higher crystallinity index than powder. Using EDX, elemental revealed presence C (49.21%) O (50.79%), while contains (46.03%) (53.93%). some variations. Various treatments applied locust bean correlate change percentage mass.

Abstract The most essential task in the twenty‐first century is to fight alarming growing pollution aquatic body which effluent of one colouring dye categories called maxilon a major contributor. This review thus specifically focuses on use nanoparticles (NPs) for photocatalytic degradation contaminants water bodies. work empirically presented performance evaluation NPs degrading dyes under light irradiation alongside underlying operational mechanism. stability was also critically analyzed by looking at regenerability and reusability expended NPs. From study, it discovered that ⋅OH O 2 ⋅ played vital role genesis oxidizing capacity breakdown dye. Moreover, found greater than 80 % shortest period < 1 hour with pseudo‐first‐order (PFO) being common kinetic best‐fit describe adsorption process occurred shortly before during operation. At end, knowledge gaps were identified area regenerability, lifecycle analyses nano‐photocatalyst fabrication utilization, cost analysis industrial scale‐up, ecotoxicological pathways. findings this study can open up insightful innovation readers industries are interested pursuing zero insecurity.

Abstract Biochar, a solid material derived from thermochemical process, has received significant attention due to its usefulness in various sectors. Previous studies have been conducted improve the properties and quality of this by altering processes, treating feedstock, hybridizing so forth, but little done on effect varying reactor's configuration. This research aims study stainless‐steel‐based combustion compartment volume biomass‐fueled top‐lit updraft gasifier groundnut shell biochar. The biochar yields for reactors ranged 34.9% 51.2%. sample produced smallest showed highest carbon content, according energy dispersive X‐ray spectroscopy (EDX) analysis. Potassium, another major element, decreased as was reduced. Scanning electron microscopy (SEM) analysis revealed that samples had an irregular shape rough surfaces, reducing resulted larger particles surface. Fourier transform infrared (FTIR) similarities differences peaks observed all samples. can find applications wastewater treatment, conversion storage, soil amendment, findings contribute design optimization biomass‐based gasifiers.

This study sheds light on the synthesis, properties, and application of plant husk-derived biomass into biochar through thermochemical conversion processes. Gasification, pyrolysis, hydrothermal carbonization, torrefaction are processes that have been used in this regard. Investigation production variables revealed temperature, carbonization duration, heating rate significantly influence yield characteristics husk-based biochar, including surface area porosity, with temperature exerting most notable impact. It was observed gave rise to a relatively higher than other processes, which may be due low temperatures usually utilized. The properties typically exhibit carbon content exceeding 45% its total weight. has applied as catalyst, for soil amendment, environmental remediation, water treatment. identification research gaps shows need further exploration intricacies well consequences socio-environmental factors, technical scalability, economic feasibility.
