A combination of three-dimensional (3D) printing and one-part geopolymer concrete is an innovative sustainable construction method to prevent environmental degradation. To perform well in a 3D application, requires rheological specifications that will generate printable. However, measuring properties interpreting the results time-consuming. It needs have standardized field-friendly assess printability before printing. This study introduces simplified way predicting for with use slump flow...
Navigable waterways play a vital role in the efficient transportation of millions tons cargo annually. Inland traffic must pass through lock, which consists miter gates. Failures and closures these gates can significantly disrupt waterborne commerce. Miter often experience fatigue cracking due to their loading welded connections. Repairing every crack lead excessive gate downtime serious economic impacts. However, if rate growth is shown be sufficiently slow, e.g., using Paris' law,...
Formamidinium lead bromide (FAPbBr 3 ) perovskites are a rapidly emerging class of materials that have the potential to revolutionize optoelectronic and photovoltaic industries.
This study aims to develop a comprehensive management model improve teaching and research effectiveness in Vietnamese universities. The purpose of the is examine key factors influencing academic performance through lens rational choice theory social exchange theory. A mixed-methods design, combining quantitative surveys qualitative interviews, was used gather data from 200 faculty members across seven universities 20 in-depth interviews with educators, administrators, policymakers. findings...
The fire performance of polyamide 6 (PA6) blended with phenyl phosphonic acid functionalized halloysite nanotubes (PPA‐HNTs) is evaluated in order to determine if there any gains over the unmodified composite. In continuing search for safe halogen‐free retardants polymers, and desire more fully capture advantages nano‐materials, this research seeks utilize synergy which might result improved PA6, via known offered by nano particles phosphorus‐based compounds. HNTs offer ability...
This paper reports an evaluation of the properties medium-quality concrete incorporating recycled coarse aggregate (RCA). Concrete specimens were prepared with various percentages RCA (25%, 50%, 75%, and 100%). The workability, mechanical properties, durability in terms abrasion cured examined at different ages. results reveal insignificant differences between (RC) reference durability-related measurements. Meanwhile, workability RC reduced vastly since replacement reached 75% 100%....
Steam-cured concrete plays an imperative role in contemporary construction, particularly the urban region where progress of project is one main keys for cost savings. However, steam curing can cause several adverse impacts on mechanical and durability performances long term. The macroscale properties are mainly controlled by cement paste. This research aims to find out appropriate treatment stage blended paste optimum quantity fly ash substituted that not only achieve design strength short...
We introduce a cationic polyamidoamine (PAMAM) dendrimers and tetronic (Te) based hydrogels in which precursor copolymers were prepared with simple methods. In the synthetic process, tyramine-conjugated (TTe) was via activation of its four terminal hydroxyl groups by nitrophenyl chloroformate (NPC) then substitution tyramine (TA) into activated product to obtain TTe. Cationic PAMAM G3.0 functionalized p-hydroxyphenyl acetic acid (HPA) use carbodiimide coupling agent (EDC) Den-HPA. 1H-NMR...
The combination of soil–cement (SC) columns and prefabricated vertical drains (PVDs) has indicated great success in improving ground stabilization recent years; however, there is a lack proper plane-strain numerical modeling to detail the role PVDs performance SC column method. This study thus presents analysis soft soil improved by coupled PVD–SC method based on proposed equivalent model considering combined effects ground. verified applying it test embankment where long were installed with...
Abstract Melt strength of polylactic acid (PLA) was improved through various modifications including grafting, crosslinking, chain extension, blending, plasticizing and nucleation. The results showed that melt increased, to varying degrees, by extension blending. In addition, strain (detected velocity) increased blending with elastomer, plasticizing, but decreased crosslinking. molecular weights, thermal properties viscosity the modified PLAs were also studied investigate causes observed...
This study is to incorporate the time-dependent development of microstructures cement-fly ash concrete into evaluation corrosion severity for newly constructed structures and existing structures. The electrical resistivity, potential, rate were determined twelve series mixtures prepared with various water-to-binder ratios, fly contents, chloride contents. developments paste, including hydration degree, pozzolanic reaction capillary porosity, are adopted based on previous models. correlation...
The metal-semiconductor heterojunction is imperative for the realization of electrically driven nanolasers chip-level platforms. Progress in developing such has hitherto rarely been realized, however, because their complexity fabrication and need to use noble metals that are incompatible with microelectronic manufacturing. Most plasmonic lase either above a high threshold (101 -103 MW cm-2 ) or at cryogenic temperature, lasing possible only after they removed from substrate avoid large ohmic...
