Composites: Their Carbon Footprint
A composite can be defined as a material composed of at least two major components that contribute in complementary ways to achieving desired performance attributes. The term “carbon footprint” is often used to refer to the same concerns, since the net emission of carbon dioxide to the atmosphere is known to contribute to increases in average temperatures at ground level on the planet.

Visualization of Cultural Heritage Objects
Cultural heritage includes everything we have inherited from previous generations. It is a valuable asset that links the past to the present. For many countries, it is both part of the national identity and an important economic engine. However, cultural heritage is constantly threatened by natural and anthropogenic factors. Therefore, the documentation of cultural heritage is very important. Registering all elements of cultural heritage has many advantages when it comes to understanding its intrinsic value, assessing its significance, and preserving and managing it.

Computational Materials Design for Ceramic Nuclear Waste Forms
Ceramic waste forms are designed to immobilize radionuclides for permanent disposal in geological repositories. One of the principal criteria for the effective incorporation of waste elements is their compatibility with the host material. In terms of performance under environmental conditions, the resistance of the waste forms to degradation over long periods of time is a critical concern when they are exposed to natural environments.

Factors in Expectation Confirmation Model
Bhattacherjee studied the continuance intention of online banking by using the ECM, which added the perceived usefulness variable in the technology acceptance model, and established a model for inspecting users’ continuance intention of an information system (IS). The ECM has four constructs: confirmation, perceived usefulness, satisfaction, and IS continuance intention. Among them, confirmation refers to the consistency between users’ expectations and the actual performance of the IS. Perceived usefulness refers to users’ expected benefits from using an IS. This construct is similar to performance expectancy in UTAUT, as both describe users’ perceived benefits from using an IS. Satisfaction refers to users’ feelings while using the IS. Finally, IS continuance intention refers to users’ intentions to continue using the IS.

Significance of the Langat River Basin, Malaysia
Approximately 2986 river basins can be found in Malaysia, but only 189 of them are viewed as significant basins dependent on the region of the basin that is >80 km2. IRBM has many cross-cutting concerns, thus accomplishing a sound IRBM will connect practically all the Sustainable Development Goals (SDGs). Langat is the UNESCO HELP (Hydrology for the Environment, Life, and Policy) River Basin in Malaysia, and distinct in its attributes because of its flow through three distinct constituencies. Langat River Basin is among the HELP basins from the 91 river basins globally, 26 river basins in the Asia Pacific region, and 3 from the south-east Asia region.

Essential Measures to Address the Worldwide Water Shortage
Climate change, global population growth, and rising standards of living have put immense strain on natural resources, resulting in the unsecured availability of water as an existential resource. Access to high-quality drinking water is crucial for daily life, food production, industry, and nature. However, the demand for freshwater resources exceeds the available supply, making it essential to utilize all alternative water resources such as the desalination of brackish water, seawater, and wastewater.

Nanofiltration Membranes Characteristics
The presence of heavy metal ions in polluted wastewater represents a serious threat to human health, making proper disposal extremely important. The utilization of nanofiltration (NF) membranes has emerged as one of the most effective methods of heavy metal ion removal from wastewater due to their efficient operation, adaptable design, and affordability. NF membranes created from advanced materials are becoming increasingly popular due to their ability to depollute wastewater in a variety of circumstances.

Geological Background of Tectonically Deformed Coal in Huaibei
Tectonically deformed coal (TDC) is a type of coal in which the primary structure of the coal body has undergone different degrees of embrittlement, fracture or ductile deformation, superimposed damage under the action of one or more periods of tectonic stresses, and even internal chemical composition and structure changes.
