Abstract

This study evaluates the performance of pressure nozzle type spray dryer. Maximum evaporation capacity was tested using water under various nozzle air pressures, airflow rates and at two inlet air temperatures. Solution of biancaea sappan extract mixed with maltodextrin were used to analyze powder yield, wall deposition, color of the powder, and efficiency of the spray dryer. An increase of nozzle air pressure and airflow rate gives finer atomization resulting in higher heat transfer. Combined with an increase in inlet air temperature, maximum evaporation capacity is achieved and can increase the powder yield of the spray dryer due to better moisture removal. Significant wall deposition was found in the head, drying chamber and cyclone duct. Visual analysis of the powder indicated that higher temperatures and prolonged residence time advanced the Maillard reaction, darkening the powder and could degrade its texture. A rather significant amount of powder loss was observed which is likely caused by fine particles leaving with exhaust air.

Abstract

This study investigates LiMn2O4 composites incorporated with nitrogen-functionalized rice husk-derived carbon as a sustainable secondary phase for cathode material development. Rice husk carbon was prepared through carbonization, acid-assisted activation, plasma treatment, and ammonia functionalization, then mechanically blended with LiMn2O4 at 2, 3, and 4 wt.% to obtain LMO-NC2, LMO-NC3, and LMO-NC4, respectively. FTIR analysis showed absorption bands at approximately 3390, 1625, 1400, 1008, 832, 702, and 460 cm⁻¹, corresponding to O–H, C=C, C=N, Si–O, and Mn–O-related vibrations. The minimum transmittance decreased from LMO-NC2 to LMO-NC4, particularly at ~1400 cm⁻¹ from 17.13% to 16.01%, indicating stronger carbon/nitrogen-related surface features. SEM revealed layered LiMn2O4, fine carbon deposits, interparticle voids, and agglomeration. XRD showed characteristic spinel LiMn2O4 indexed to the (111), (311), (222), (400), (331), (511), and (440) planes. BET adsorption volume increased from 160 cc/g for LMO-NC2 to approximately 169 and 176 cc/g for LMO-NC3 and LMO-NC4 at P/P₀ = 0.31. These findings demonstrate the potential of rice husk-derived carbon for sustainable LiMn2O4 composite design, supporting responsible consumption and production under SDG 12.

Abstract

Fiber orientation plays a major role in controlling the mechanical properties of natural fiber bio composites. An investigation into the impact of fiber direction variations on the toughness and tensile strength of burlap waste composites for automobile bumpers was carried out. This research was designed as a controlled experimental investigation. The factors evaluated were fiber orientation, while the tensile strength and impact toughness were. Bio composites were manufactured utilizing the hand lay-up procedure, and mechanical testing included tensile (ASTM D638) and impact (ASTM 4812). The number of test replications was fixed at three specimens for each variable. By improving interfacial adhesion, the 0°/+90°/0°/+90°/0° fiber orientation produces a tensile strength of 21.087 N/mm² and an impact toughness of 0.0482 J/mm², which is higher than a car bumper. These research show proof that burlap sack waste-based composites can be used as an alternative material for environmentally acceptable and sustainable bumpers. These findings complement SDG 12, which focuses on responsible production and consumption.
