Graphene aerogel (GA) was synthesized by chemical reduction of graphene oxide (GO) using ethylene diamine as a reducing agent, which was then followed by a freeze-drying process. In this work, we produced GA by hydrothermal process followed by freeze-drying. The produced adsorbent was then deployed to study the TC adsorption process.

In this study, the gold nanoparticles (AuNPs) were synthesized via redox reaction, by using ethylene diamine tetra-acetic acid (EDTA) as a protecting and reducing agent, with tetrachloroauric acid (HAuCl4) as precursor and seed solution. The ultraviolet-visible spectroscopy (UV-Vis) method was utilized to investigated the reaction conditions (the EDTA:HAuCl4 ratio, the amount of seed solution and stirring solution time) at room temperature. The synthesized AuNPs were deposited on the surface of fluorine doped tin oxide (FTO) by electrophoresis deposition.

The plasmon characterization of AgNS on paper was systematically investigated by the diffuse reflectance spectroscopy. The fabricated paper-based SERS substrates were used to detect melamine in an aqueous solution and to determine the influence of type RAs on the enhancement factor (EF) and signal uniformity of SERS substrates. Among the four types of RAs, the SERS substrates used NaBH4 have the highest SERS signal with the limit of detection of 10-8 M for melamine and the EF = 2.3 × 109 .

The present study focuses on the preparation of silver/copper bimetallic hybrid nanoparticles by green method from precursor solutions of silver nitrate & copper nitrate and the locally available citrus fruit (lemon) peel extract which behaves as the stabilizing and reducing agent. Initially, the formation of hybrid nanoparticles was noticed in the reaction mixture by colour change.

In this work, gold nanorods (AuNRs) with well-controlled aspect ratios were prepared using a modified seedgrowth method and covered by TiO2 layers through the hydrothermal reaction to improve stability. Integrating TiO2 with plasmonic rod-like gold nanoparticles could enhance their photo activity by the local surface plasmon resonance (LSPR) effect. AuNRs aspect ratios were controlled by varying the amount of seed solution, reducing agents, surfactant (CTAB), and titanium (IV) but oxide.

House of Risk Method is used to identify the most potential risk agents, while the fuzzy reasoning risk assessment model is used to determine the risk severity by risk agents. Based on the analysis, it is found that risk agent stock out of the product is the most potential risk agent in this industry. To reduce the impact, mitigation strategies are suggested for stock out product risk agents in warehouse are flexible supply base, safety stock, internal coordination, as well as create and control production schedules.

Ebook "Artemisia annua - Pharmacology and biotechnology" is an effective antimalarial agent, particularly for multi-drug resistant and cerebral malaria. However, the concentration of artemisinin in the plant is very low. Because the chemical synthesis of artemisinin is complicated and not economically feasible in view of the poor yield of the drug, the intact plant remains the only viable source of artemisinin production. Therefore, it is necessary to increase the concentration of artemisinin in A. annua to reduce the cost of artemisinin based antimalarial drugs.
