However, due to the lack of rigid formwork for support, 3D printing concrete faces challenges in controlling the flow of fresh concrete and the dimensions after curing. Therefore, controlling the rheological properties to ensure the integrity and basic mechanical properties of 3D printing structures has become a key focus for the advancement. This paper employs bibliometric analysis to review relevant literature from the past decade and discusses various factors influencing the rheological properties of 3D printing concrete. First, a series of rheological models proposed by previous studies are examined and compared. Next, the impact of rheological properties on key factors such as pumpability, extrudability, buildability, and open time is discussed, along with an analysis of the various factors that affect these properties. Finally, the experimental methods and standards for assessing rheological properties are compared and summarized, with predictions made regarding the future development prospects and trends for 3D printing concrete. In general, research on the rheological properties of 3D printing concrete and the development of environmentally friendly materials have become key future development directions and research hotspots. To better ensure the calculation and evaluation of rheological properties, the development of appropriate rheological models and rheometers is essential. At the same time, optimizing material mix ratios and incorporating suitable additives can better control the rheological properties and printability. Finally, as the development of rheological, it is crucial to further improve national standards and experimental methods to enhance consistency and reliability in 3D printing concrete applications.</div></div>","PeriodicalId":100958,"journal":{"name":"Next Materials","volume":"11 ","pages":"Article 101736"},"PeriodicalIF":0.0,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146173619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The choice of an appropriate processing method determines the sequence and duration of each stage, ultimately influencing both investment and operational costs. This review examines the encapsulating of natural rubber using spray drying technology and its market prospects. Conventional natural rubber processing involves intensive stages and a considerable amount of equipment, such as coagulation, milling, pre-drying, shredding, and drying. Simplifying this lengthy procedure and minimizing the need for intensive equipment can be achieved by employing encapsulation technology through spray drying. One of the key factors in the encapsulation of natural rubber particles is the use of non-adhesive additives, which help reduce the inherent tackiness of natural rubber. These additives act as encapsulating agents, enveloping natural rubber particles and preventing stickiness between them. The selection of additive materials is one of the crucial factors in applying spray drying technology for natural rubber. Given its numerous advantages, spray drying technology is suitable for small-scale applications, particularly in smallholder plantations. Encapsulated natural rubber products exhibit significant market potential as innovative alternatives. Several studies have investigated the drying process of natural rubber using spray drying technology with various encapsulating material alternatives. The results of these studies indicate that natural rubber latex can be processed into encapsulated natural rubber. Further comprehensive research is needed to evaluate its applicability in the production of end-use rubber products.</div></div>","PeriodicalId":100958,"journal":{"name":"Next Materials","volume":"11 ","pages":"Article 101592"},"PeriodicalIF":0.0,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145980592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated the potential use of copper oxide nanoparticles (CuO NPs) synthesized by Co-Precipitation and heat-treated for varying durations at different temperatures (200°C to 800°C, 2–6 h) as nano-priming agents for tomato (Solanum lycopersicum cv. Aahan F1) seeds. Structural and surface Characterizations, such as UV -Vis, XRD, FTIR, FESEM, DLS, and zeta potential, revealed that calcination temperature and time had a significant impact on particle size, crystallinity, and surface charge of CuO NPs. The best result was obtained by calcining at 600°C for 4 h, which produced particles with improved crystallinity, an average size of approximately 80 nm, and a zeta potential of −16.84 mV. These conditions favoured interactions between the seeds and the NPs. The tests indicated dose-response when seeds were treated with different NP concentrations, 5–100 mg/L. Low to moderate concentrations of 50–70 mg/L significantly improved germination rates, reaching up to 95 %, along with seedling vigour, biomass, and root-shoot growth. However, concentrations over 100 mg/L caused oxidative stress, which hindered growth and led to harmful effects on the plants. The influence of calcination time at a steady temperature (600°C) also showed that longer heating (6 hrs) resulted in clumping and less stability, while (4 hrs) offered the best colloidal properties and uniform shape. These results highlight the important role of heating conditions in optimising nanoparticle efficiency. This research suggests that calcination-engineered CuO NPs are an eco-friendly, scalable, and effective strategy for seed nano-priming that can promote early plant growth, serving as a promising alternative to traditional agrochemicals.</div></div>","PeriodicalId":100958,"journal":{"name":"Next Materials","volume":"11 ","pages":"Article 101638"},"PeriodicalIF":0.0,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146079232","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, achieving regioselective synthesis of these multi-adducts remains challenging. Notably, the regioselective multi-functionalization of a malonate cyclopropane fullerene monoadduct has already been demonstrated, yielding a single tetra-addition pattern through a supramolecular mask strategy. In this study, we explore how the nature of the existing functional groups influences the Bingel multi-addition reaction of diethyl bromomalonate on different mono-functionalized fullerenes. To investigate this, we synthesized fullerene derivatives bearing either long, flexible chains, or a rigid dibenzodioxin moiety via the corresponding Diels–Alder reaction of <em>o</em>-dibromomethyl arenes with C<sub>60</sub>. These derivatives were then encapsulated within a supramolecular cage and subjected to multi-functionalization conditions. We monitored the reaction’s progress and final products using high-resolution mass spectrometry (HRMS), UV-Vis, and <sup>1</sup>H-NMR spectroscopy. These studies show that derivatives bearing different initial functionalities exhibit distinct multi-functionalization outcomes. We provide a detailed rationalization of the experimental observations.</div></div>","PeriodicalId":100958,"journal":{"name":"Next Materials","volume":"11 ","pages":"Article 101612"},"PeriodicalIF":0.0,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146079230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
