Industrial processes and the building sector (e.g., for space and water heating) are responsible for the majority of the total energy consumed for heat. Although fossil fuels remain to dominate the heating sector, renewable heating technologies have been lately widely deployed. Thermochemical energy storage (TES) can be a promising advanced technology in addressing the mismatch between renewable energy supplies and the end-user’s demand. In this paper, a novel Vermiculite-based Solar Thermochemical Heat Storage (VS-THS) system was proposed for domestic space heating applications, which could also overcome the intermittency challenges and realise long-term solar energy storage. A small-scale prototype was set up to evaluate the energy storage performance of the proposed system using a patented ChainStore panel to accommodate vermiculite-based composite. The unique design of the ChainStore arrangement offers great heat and mass transfer and good flexibility for system resizing in the case of varying the building energy demand. Due to the low regeneration temperature (63 °C) and high energy storage density (253.8 kWh/m 3 ) of the vermiculite-based adsorbent impregnated with MgSO 4 and CaCl 2 , it was chosen as the THS composite in the experiments. The experimental results showed that the proposed VS-THS is feasible for domestic space heating, with the highest space heating supply temperature of 37.6 °C, and the system COP in the reaction process is In addition, the results also demonstrate that the composite of vermiculite impregnated with MgSO 4 and CaCl 2 , with a good water adsorption performance. This proposed concept of VS-THS could be sized for different building applications.

This study aimed to explain the pattern of development of settlements on the banks of the Lasolo River, and the factors affecting it. This study was located in a riverbank in Kendari, Southeast Sulawesi-Indonesia. It was conducted using a qualitative descriptive approach with observation, naturalistic, and phenomenological methods to reveal phenomena that occur based on observations and information obtained in the field. The results of this study indicate that the development of residential areas on the banks of the Lasolo River started from the north (residential area 01) to the east (residential area 02) along the banks of the river. The pattern of development of residential area 01 vary. The pattern of settlement group 01 in settlement A is linear, also regular and street-oriented; settlement B is cluster, irregular, street and river-oriented; settlement C is cluster, irregular, and street-oriented. Meanwhile, settlement 02 that consists of settlement D is cluster, regular, also street-oriented, and river-oriented. The results also found that the pattern of development of settlements is influenced by the number and density of the population, socio-cultural-economic, physical environment, and community empowerment activities.

Dubai was developed from Khor Dubai and the city always focuses on the development of waterfront as a public space. The urban waterfront in Dubai is a highly visible public space for recreational activities but also as an urban landscape for placemaking, environmental pollution reduction, and transportation. The objective of this study is to explore the direction of future development of the Dubai Water Canal. By analyzing the characteristics and behavioural patterns of canal users using a post-occupancy evaluation survey, the study presents the management plan necessary to improve the facility. As a methodology, Post-Occupancy Evaluation (POE) with two-step cluster analysis was used with SPSS Statistics version 20.0. Dubai Water Canal users were classified into friend-based, family-based, and individual-based clusters to investigate the differences in satisfaction levels and perception between clusters. The survey included questions on accessibility, convenience of use, facility management status, safety, and landscape management. The result had shown that family-only parking, convenient pedestrian walkway, signage/distance marker, and pocket parks as green buffer zones are needed to increase the level of satisfaction. Factors to enhance users’ satisfaction comprised 1) efficient road system for light exercise, 2) efficient information signage, 3) convenient pedestrian roads with nighttime lighting system, 4) strict separation of pedestrians and cyclists, and 5) nature-friendly landscape and landscape improvement. This study intended to extract elements for future design and management of urban open space projects, similar to the Dubai Water Canal.

Soils are the primary carriers of heavy metals released into the environment by many different anthropogenic activities. Unlike organic pollutants, which are oxidized, most metals do not undergo microbial or chemical degradation, and their concentration in the soil continues for a long time. Increasing social awareness of the need to adequately address mineral waste to protect the environment has led to increased research in this area. Contemporary trends and the development of technology have revealed numerous methods of cleaning these degraded lands and what would best serve such an area. Based on centuries of historical development, botanic gardens have developed globally leading conservation, research, education, and recreation institutions. Botanic gardens increasingly provide a scientific basis for sustainable use and protection of plant diversity. This research aims to analyze the methods of treatment of these areas, then give a proposal which, in addition to solving a severe problem of this municipality, will become a research and study area for students of various fields related to botany. The investigation line is constructed on: analysis, field research, literature review, data provided by the municipality of Gracanica, interviews, and online surveys. Through this research, we will understand user expectations, spatial preferences, and the intended purpose of the Kosovo Botanical Garden and will convey them through the proposal into a functional concept and present new solutions, modern and practical, in this facility.

Biomass-based aerogel is a new promising environmentally friendly filter material to remove fine particle matter and minimize air pollution. This study aims to investigate the air filtration properties of biomass-based aerogels via tests in a transparent chamber and verification in a real room with a burning smudge stick as a the particle source. The biomass-based aerogel used in this study is made of polysaccharides, protein and waste agricultural by-product (wheat straw). The addition of wheat straw contributes to the increase of surface area and complexity of the biomass-based aerogel pore structure. Compared with other commonly used commercial filtration materials including high-efficiency particulate air (HEPA) filter, surgical mask, regular cloth and silica aerogel, biomass-based aerogel K0.9G1.8S3.6WS1.8 shows excellent performance to remove PM 2.5 (99.50%) and PM 10 (99.40%) from the environment. When using the biomass-based aerogel, the filter core sample has a smaller volume and simpler structure than HEPA to achieve the similar filtration performance. The filtration performance of the biomass-based aerogels has been verified with a real room test. The current work demonstrates the high potential of biomass-based aerogels for infiltration application in different fields and provides an avenue to reuse agricultural by-products.
