Nghiên cứu nhằm mục đích tạo nhũ tương nano dầu neem bằng phương pháp điểm đảo pha, kết hợp với nano silica và xác định hiệu quả kháng nấm Pyricularia orizae. Khảo sát các...

Acrylic resin is a denture base material mostly used in the fabrication of removable partial denture and complete denture because it is easy to process, economical and aesthetically satisfying. However, the acrylic resin...

Abstract Semi-flexible pavement (SFP) combines the flexible properties of asphalt with the rigidity of a cementitious slurry, providing improved structural and durability performance. However, the reliance on ordinary Po...

Abstract Sodium carbonate-activated slag mortar (SCASM) exhibits the advantages of low shrinkage, high strength in late age, and low-cost and carbon emissions. However, its microstructure is relatively porous due to the ...

Preparó nanocompositos de polietileno y polipropileno mediante la polimerización in situ con catalizadores metalocénicos.

Estudia la extracción de cobre y cinc desde soluciones acuosas ácidas.

To date, control strategies used against insect pest species are based on synthetic insecticide applications. In addition, the efficacy of these treatments could be decreased due to insecticide resistance in insect popul...

Abstract Growing environmental problems and the threat of an energy crisis have created an urgent need for affordable and efficient photocatalysts that can work under UV light to remove pollutants. In this work, Zinc fer...

In this study, ordered mesoporous carbons CMK-3 were prepared by a nanocasting method using SBA-15 silica as template and sucrose as carbon source. The pure CMK-3 was modified with nickel by wet impregnation method and t...

The properties of two new lipophilic isomeric phthalocyanines 2,9(10),16(17),23(24)-tetrakis-[(2-dimethylamino)ethylsulfanyl] phthalocyaninatozinc(II) (Pc9) and 1,8(11),15(18),22(25)-tetrakis[(2- dimethylamino)ethylsulfa...

Geopolymers are known for its high compressive but low tensile strength due to its brittle nature, which restricts the use of geopolymers as structural material. It is important to enhance their mechanical performance by...

A method for the polymerization modification of nanoscale fumed silica by crosslinking a lignin layer adsorbed on a nanosilica surface under a gas dispersion medium is described. A mixture of phenol and formaldehyde in t...

Silicon dioxide (SiO2), a material known as “silica” presents properties that make it a good candidate as a biomaterial: it has a very labile surface for functionalization, it is easy to synthesize and it is biocompa...

Polyisoprene (PI), whether naturally or synthetically produced, is used in rubber compounds for many applications, such as tires, belts, and shoes. The effect of Nano ternary silica (NTS) addition on the thermal and mech...

Abstract Silver nanoparticles show promise anticancer agents, yet their clinical translation is hindered by poor bioavailability and nonspecific toxicity. In this study, we developed an apigenin-functionalized silica-coa...

A new bimetallic heterogeneous catalyst consisting in copperand palladium nanoparticles supported on bio-silica is presented. The useof TEMPO as co-catalyst allowed the aerobic oxidation of primary benzylicalcohols into ...

Herein we report a facile method for the preparation of hierarchical silica nanostructures through a biomimetic approach. Toward this goal, a protein-directed approach has been proposed to template silica into 3D archite...

The soft liner of acrylic resin dentures, used to coat removable partial dentures, still has drawbacks in the easy attachment of Candida albicans fungus. A treatment on the surface of the acrylic resin denture soft liner...

Abstract Background Nanodelivery represents a promising strategy to enhance pesticide efficacy while reducing associated environmental risks. Mesoporous silica nanospheres (MSNs) can serve as effective nanocarriers but i...

The influence of Au nanorods coated with a silica layer on the photoluminescence (PL) of CdTe quantum dots (QDs) was investigated. The Au nanorods were prepared using a seed-mediated method. They were coated with a silic...

The processes occurring in hydrated powders and concentrated suspensions of hydrophobic silica were studied by 1H NMR spectroscopy. It is shown that a mixture of methyl silica and water with a hydration of less than 1 g ...

In this work, we apply the recently developed frequency shift of nanoantennas (FRESA) technique to measure the Young’s modulus of thin mesoporous films at GHz frequencies as a function of porosity with local precision....

Abstract Optically trapped silica nanoparticles are a promising tool for precise sensing of gravitational or inertial forces and fundamental physics, including tests of quantum mechanics at “large” mass scales. This ...

Cellulose acetate and polyisocyanate copolymer synthesized by mechanical mixing of cellulose acetate, polyisocyanate and fumed silicon dioxide in the presence of nickel chloride was carbonized in silicon dioxide template...
