Title: Liquid Smoke characterisation and production from empty fruit bunches via consecutive pascalisation and microwave-assisted pyrolysis Authors: Rachmaniah, O; Meka, W; Nurkhamidah, S; Saputra, NDS; Ashshiddiqi, MK; Tan, TB; Tan, CP; Fahrudin Rois, M; Lalasari, LH; Vanin, FM; Masoudi Soltani, S Abstract: Empty fruit bunches (EFBs) were pascalised at 200–400 MPa, then pyrolysed with microwave oven at 350 and 450 °C. Physical and thermal properties of EFBs were characterised. Yields, chemical compositions, and functional properties including total phenolic content, antioxidant capacity, acidity, antimicrobial activity, and colour of the liquid smoke were also evaluated. Results showed that pascalisation at 300 MPa produced the maximum surface area of 6.385 m2 g−1 and pore volume of 0.5511 cm3 g−1, whilst pascalisation at 400 MPa caused pore collapse. Liquid smoke yield showed irregular trends: at 350 °C, 400 MPa achieved the highest yield of 21.2 ± 2.3% despite collapsed pores, whilst 200 MPa yielded the lowest at 5.2 ± 1.4%; at 450 °C, the trend reversed, with 200 MPa reaching the highest yield of 11.9 ± 1.7% whilst 400 MPa fell sharply to 5.4 ± 2.0% due to rapid heating rate. GC–MS analysis identified phenolic compounds and ketones, showing compositional shifts related to pore structure modifications. The irregular trend of most functional properties suggests that densified EFB structures concentrated phenolic compounds whilst more open structures produced dilute liquid smoke. These findings demonstrate that pascalisation modifies EFB structure and influences liquid smoke yields and composition through structural mechanisms. Description: Highlights: • Pascalisation at 300 MPa optimised EFB mesoporosity for pyrolysis efficiency. • Pressure-temperature interaction governed liquid smoke yield and phenol content. • 400 MPa/450 °C maximised antimicrobial activity via phenol-pH synergy. • Samples met SNI colour/pH standards, but high TPC requires phenol control. • Post-condensation fractionation proposed to achieve regulatory compliance.; Data availability: The authors declare that all produced data have been presented in this paper.; Supplementary data are available online at: https://www.sciencedirect.com/science/article/pii/S2589014X26002239#s0160 .

Title: Characterising phase transition and thermal behaviour of phase change material with nanobubbles: A comparative molecular dynamics study Authors: Hassanloo, H; Wang, X; Yang, Y Abstract: Global warming and the rising demand for sustainable energy have intensified interest in efficient thermal energy storage. Phase change materials (PCMs) offer high latent heat storage capacity but have poor thermal performance. By incorporating nanoscale additives, nano-enhanced PCMs can improve overall efficiency in renewable energy applications. Nanobubbles (NBs), gaseous cavities under 1 μm, have unique properties that make them promising candidates for various industrial applications, including in the energy and power sectors. Molecular-level approaches can provide valuable insights into the thermal effects of NBs. In this study, molecular dynamics simulations were employed to simulate the phase transition behaviour and thermal properties of NB enhanced dodecane. This study explored different NBs of hydrogen, nitrogen, and oxygen and compared with the pure dodecane in comparative analysis. The findings demonstrate that the incorporation of NBs, particularly hydrogen NB, depresses the liquid-to-solid transition temperature of dodecane. Additionally, the presence of NBs enhances both thermal conductivity and specific heat capacity, with nitrogen NBs yielding the highest increase in thermal conductivity by approximately 14 %. Furthermore, nitrogen and hydrogen NBs were identified as promising candidates for high-temperature applications due to their stability over a wide temperature range; however, their presence also results in an increase in viscosity.
