Summary: This paper presents an exploratory literature review on the hydration and rheological properties of cementitious composites with acai fibers. Acai fiber is a potentially promising option for reinforcing cementitious matrices due to its unique characteristics. However, there is a lack of knowledge regarding the relationship between fiber parameters and composite properties, hindering the development of new applications such as 3D printing. The review provides an overview of the main characteristics of acai fibers and their application parameters in cementitious composites. Alkali treatment with 5% NaOH solution for 1 hour enhances the mechanical and physical properties of acai fibers. Challenges arise from the different fiber surface treatments and interfacial transitions, as well as the processing conditions of the fibers. Although a small addition of acai fibers slightly slows down the cement hydration process, it still maintains a high cross-compatibility index (>95). To address these challenges, it is crucial to evaluate the rheological behavior of cementitious materials with acai fibers, which has not yet been reported in the literature. This evaluation will facilitate the optimization of processing conditions and the exploration of new applications, such as additive manufacturing, with acai fibers.

Summary: Recently, research has shown the increasing importance of natural fiber in various industries such as medicine, aerospace, and agriculture. Natural fiber is preferred due to its eco-friendly nature and excellent mechanical properties. This study aims to increase the use of environmentally friendly materials, specifically in brake pads. By comparing natural fiber composites with Kevlar-based composites, it was found that composites with 5 wt.% sugarcane fiber outperformed the entire natural fiber composite in terms of coefficient of friction, fade, and wear. However, mechanical properties were similar. The study also found that the Kevlar-based brake pad specimens provided superior outcomes compared to the sugarcane fiber composite for fade, wear performance, and coefficient of friction. Scanning electron microscopy was used to examine the worn composite surfaces and understand the wear mechanisms and tribological behavior of the composites.

Summary: Over the past twenty years, analytical chemistry scientists have developed tools to evaluate the environmental impact of their methods. This study reviews these tools using criteria inspired by the life cycle assessment framework. The results demonstrate that the reviewed tools are user-friendly but have limitations in scope and rely on subjective weighting schemes. The study discusses the strengths and weaknesses of life cycle assessment as a complementary approach and illustrates its ability to provide quantitative and comprehensive information on the environmental performance of analytical chemistry methods. However, implementing life cycle assessment is time-consuming, requires expertise, and is not suitable for routine application. The study concludes by identifying key challenges for the application of life cycle assessment in the field of analytical chemistry.

Summary: This study investigated the effects of different plasticizers (glycerol, fructose, sorbitol, and urea) on the morphological, mechanical, thermal, and physical characteristics of wheat starch films at various concentrations. The addition of plasticizers improved the flexibility and homogeneity of the films. Films plasticized with 35% sorbitol showed the highest elongation, while fructose showed the highest tensile strength at 35%. Glycerol films had the lowest water absorption at 35% fructose and showed coherent surfaces. Fructose exhibited the best performance with low water absorption, water content, and mass loss, and high mechanical performance at 35% concentration. SEM images showed that fructose and glycerol improved surface homogeneity, while sorbitol and urea had a less compact structure with large pores.

Summary: The study examines the use of black seed fiber as a reinforcing material for cornstarch-based biocomposites. Different concentrations of black seed fiber and a plasticizer mixture were used to fabricate the biocomposites. The results showed that increasing the black seed fiber concentration improved the mechanical properties and thermal stability of the films, but decreased biodegradability. The addition of black seed fiber has the potential to enhance the performance of biopolymers in response to community needs and environmental concerns.

Summary: In this study, the friction and wear properties of Furcraea foetida fiber-reinforced epoxy composites were investigated. The effect of fiber content on the tribological behavior of the composites was evaluated. The results showed that the composite with 50 vol% of fibers had the lowest frictional force and coefficient of friction (COF), while the composite with 60 vol% demonstrated the best wear resistance. This study provides valuable insights into the tribological behavior of the composites and identifies the optimal volume fractions for improved friction and wear performance.

Summary: This study investigates the influence of hybrid reinforcements, namely CaCO3 particles and bentonite nano clay, on the wear and friction properties of high-density polyethylene (HDPE)-based composites. The results demonstrate a significant improvement in wear resistance, with the synthesized hybrid composite achieving a maximum improvement in wear rate of 93%. Morphological analysis reveals that the encapsulation and compatibilization effect of bentonite nano clay contribute to the improved wear performance. The prepared composite with enhanced tribological properties shows potential for use in low load-bearing wear applications such as turbo nanogenerators and piezo nanogenerators.

Summary: The paper proposes a novel deep learning-based prediction framework, aTCN-LSTM, for accurate cooling load predictions. The framework utilizes a gate-controlled multi-head temporal convolutional network and a sparse probabilistic self-attention mechanism with a bidirectional long short-term memory network to capture both temporal and long-term dependencies in the cooling load sequences. Experimental results demonstrate the effectiveness and superiority of the proposed method, which can serve as an effective guide for HVAC chiller scheduling and demand management initiatives.
