  Thermal Energy Storage Performance of EPCM-Impregnated Moss Biomass Placed in OKAL Chipboard for Use in Building Envelopes and Interior Space Separation

  Can, Ahmet; Erata, Hüseyin; Gencel, Osman; Erol, Tuğçenur Bayraktar; Sarı, Ahmet; Batan, Nevzat

  This study develops an innovative thermal energy storage approach for lightweight building systems by using eutectic phase change material (EPCM)-impregnated moss biomass (Cp/EPCM) in the internal voids of OKAL chipboard (OKS-Cp/EPCM). A high latent heat storage (LHS) capacity of 121.4 J/g was achieved with a 72% EPCM loading. Furthermore, the thermal conductivity of the OKS-Cp/EPCM decreased from 0.15074 W/m·K to 0.109 W/m·K. Thermal imaging results showed that the OKS-Cp/EPCM improved thermal comfort by reducing the surface temperature by approximately 10.5 °C in hot environments and providing an approximately 1 °C higher surface temperature in cold environments. However, TGA analyses revealed that the thermal resistance of the composite was limited. Relative humidity results also indicated that Cp/EPCM positively contributed to the moisture regulation performance of the board. Based on these results, OKS-Cp/EPCM offers a promising solution for the development of energy-efficient and thermally comfortable lightweight building elements.

  Valorization of Moss biomass as a natural porous Matrix for shape-stable phase change material (PCM) composites

  Can, Ahmet; Ganguly, Sauradipta; Gencel, Osman; Sarı, Ahmet; Erata, Hüseyin

  Phase change materials (PCMs) are used to improve energy efficiency, particularly in building heat storage and passive thermal management applications. In this study, moss biomass ( Calliergonella cuspidata (Hedw.) Loeske) (Ca) was evaluated as a natural porous matrix, and a novel non leachable composite phase change material (PCM) was developed based on n-octadecane (n-OD). The moss biomass was impregnated with 60% n-OD by direct mixing method, and its structural stability was enhanced by the addition of Sodium silicate (SS) at 10% and 30% (by wt%) respectively. The morphological, chemical, and thermal properties of the composites were characterized by SEM, EDS, FTIR, DSC, TGA, XRD, and thermal conductivity analyses. SEM-EDS results showed that the moss biomass (Ca) had high porosity, with the addition of SS resulting in a more compact and homogeneous structure. FTIR analyses exhibited the formation of Si–O–Si bands, indicating successful integration of SS into the matrix. According to DSC analysis, the Ca/n-OD(60%) composite had a melting temperature of 26.1 °C and a melting enthalpy of 153.7 J/g whereas for the SS-added variants, these values were measured as 148.3 J/g (10%) and 144.2 J/g (30%), respectively. The enthalpy losses of only 2–3 J/g after 700 heating-cooling cycles indicated high thermal stability. TGA and XRD analyses showed that the addition of SS increased the thermal resistance of the composites, creating an amorphous network structure. The results indicate that moss-based Ca/n-OD/SS composites, with their compact, leak-free structure, high heat storage capacity, and excellent cyclic stability, hold promise as eco‑friendly materials for subsequent applications in: thermal energy storage for buildings, solar energy systems, and the thermal management of electronic components.

  The Epiphytic Bryophyte Vegetation of the Karçal Mountains (Artvin, Türkiye)

  Batan, Nevzat; Özcan, Osman; Ezer, Tülay; Erata, Hüseyin; Alataş, Mevlüt

  Abstract: In this study, the epiphytic bryophyte vegetation of the Karçal Mountains (Artvin) in the Caucasus Region was investigated. Relevés collected from living tree trunks during various vegetation periods in 2022 were analyzed using the Braun-Blanquet method and multivariate analysis techniques. As a result, Anomodontetum attenuati-Ulotetosum crispae subass. nov. was described and characterised as a new epiphytic syntaxa. In addition, Orthotrichetum rupestris, Orthotrichetum speciosi, Uloto crispae-Orthotrichetum striati, and Anomodonto viticulosi-Leucodontetum sciuroidis-Anomodontetosum attenuati were determined for the first time in Türkiye. All syntaxa were presented by analyzing them in terms of their ecological and floristical classifications.
