Ultrasensitive determination of chloramphenicol in pork and chicken meat samples using a portable electrochemical sensor: effects of 2D nanomaterials on the sensing performance and stabilityAuthors: Ngo Xuan Dinh; Tuyet Nhung Pham; Tran Quang Huy; Do Quang Trung; Pham Anh Tuan; Vu Quang Khue; Nguyen Van Quy; Van Phan Le; Vu Dinh Lam; Anh-Tuan Le; Advisor: -; Co-Author: - (2021)Functional two-dimensional (2D) structured nanomaterials, such as, graphene oxide (GO) and molybdenum disulfide (MoS2), exhibit many advantages, including large surface areas and excellent electronic/mechanical/catalytic properties, and have shown to be s

Ultrasensitive Detection of Methylene Blue Using an Electrochemically Synthesized SERS Sensor Based on Gold and Silver Nanoparticles: Roles of Composition and Purity on Sensing Performance and ReliabilityAuthors: Mai Quan Doan; Nguyen Ha Anh; Nguyen Xuan Quang; Ngo Xuan Dinh; Doan Quang Tri; Tran Quang Huy; Anh-Tuan Le; Advisor: -; Co-Author: - (2021)An electrochemical approach has been used for green synthesis of gold and silver nanoparticles (e-AuNPs and e-AgNPs) with high levels of purity and scalability. The electrochemically synthesized noble-metal nanoparticles were characterized by ultraviolet–visible (UV–Vis) spectroscopy and scanning electron microscopy (SEM), confirming the formation of spherical e-AuNPs and e-AgNPs with average size of 19 nm and 24 nm, respectively. These green nanoparticles were deposited on aluminum substrates using the drop-drying method for surface-enhanced Raman scattering (SERS)-based detection of Methylene Blue (MB) within the ranges from 10−5 M to 10−8 M and 10−7 M to 10−10 M, respectively. The ...

The nitrogen slow-release fertilizer based on urea incorporating chitosan and poly(vinyl alcohol) blendAuthors: Phong Thanh Vo; Huu The Nguyen; Hai Thi Trinh; Viet Minh Nguyen; Anh-Tuan Le; Huy QuangTran; Thuy Thi Thu Nguyen; Advisor: -; Co-Author: - (2021)For mitigating environmental pollution caused by excess usage of urea fertilizer, this paper reports a new fertilizer formulation, based on urea incorporating chitosan (CS) and poly (vinyl alcohol) (PVA) blend, for the slow release of urea. The urea/CS/PVA formulations were prepared by cross-linking CS and PVA blend in the presence of urea with glutaraldehyde as a cross-linker. The results indicated an interaction between urea and the functional groups of CS and PVA through hydrogen bonding, which has significant effects on the thermal properties of urea/CS/PVA formulation. The surface morphology of urea/CS/PVA formulations showed that the quantity of urea crystals anchored on the sur...

Scalable Electrochemical Synthesis of Novel Biogenic Silver Nanoparticles and Its Application to High-Sensitive Detection of 4-Nitrophenol in Aqueous SystemAuthors: Van-Tuan Hoang; Ngo Xuan Dinh; Tuyet Nhung Pham; Tran Vinh Hoang; Pham Anh Tuan; Tran Quang Huy; Anh-Tuan Le; Advisor: -; Co-Author: - (2021)This study reports a scalable green electrochemical synthesis of novel biogenic silver nanoparticles colloid (biogenic AgNPs) in large scale up to 5 liters using the bulk silver bar and the green tea leaves (Camellia sinensis) extract (GTE) as reducing ag

Novel Eco-Friendly Synthesis of Biosilver Nanoparticles as a Colorimetric Probe for Highly Selective Detection of Fe (III) Ions in Aqueous SolutionAuthors: Nguyen Le Nhat Trang; Van-Tuan Hoang; Ngo Xuan Dinh; Le Thi Tam; Van Phan Le; Dong Thi Linh; Doan Manh Cuong; Nguyen Tien Khi; Nguyen Ha Anh; Pham Tuyet Nhung; Anh-Tuan Le; Advisor: -; Co-Author: - (2021)In this work, an eco-friendly approach for the synthesis of biogenic silver nanoparticles (bio-AgNPs) using botanical extracts in combination with an electrochemical process was carried out. We employed three types of plant extracts, including green tea leaf (GTE), grapefruit peel (GP), and mangosteen peel (MP) extracts to successfully synthesize the bio-AgNPs and optimized the experimental conditions aiming to get the highest synthetic yield. The formation of bio-AgNPs was monitored by UV-Vis spectroscopy via a surface plasmon resonance (SPR) band at about 420–430 nm. Transmission electron microscope (TEM) showed their spherical shape with the size range within 23–55 nm. While X-ray ...

Improving SERS Sensing Efficiency and Catalytic Reduction Activity in Multifunctional Ternary Ag-TiO2-GO Nanostructures: Roles of Electron Transfer Process on Performance EnhancementAuthors: Mai Quan Doan; Nguyen Ha Anh; Hoang Van Tuan; Nguyen Cong Tu; Nguyen Huu Lam; Nguyen Tien Khi; Vu Ngoc Phan; Pham Duc Thang; Anh-Tuan Le; Advisor: -; Co-Author: - (2021)Multifunctional nanocomposites have received great attention for years; electron transfer (ET) is considered as an explanatory mechanism for enhancement of performance of these nanostructures. The existence of this ET process has been proved in many studies using either experimental or computational approaches. In this study, a ternary nanocomposite system of Ag/TiO2/GO was prepared to evaluate the performance enhancement in two experimental models: a physical model (i.e., surface-enhanced Raman scattering (SERS) sensor) and a chemical one (i.e., catalytic reduction reaction). The metal/semiconductor heterojunction between Ag and TiO2, as well as Ti-O-C bonds, has allowed plasmonic ho...
