PRODUCTS

Custom Synthesized Advanced Functional Products 

Dr. Ram is keen to supply the custom synthesized advanced materials for organic electronics, environment and energy research applications. Dr. Ram is having the expertise in the synthesis of nanomaterials such as organic dispersible chemically exfoliated graphene oxide, substrate immobilized TiO2 photocatalysts, Nano-Silver, and piezoelectric PVDF films. Besides, we can provide the tailor made organic compounds for organic, medicinal and energy related applications. We are also engaging the photocatalysis testing services. We have expertise in analyzing the newly synthesized photocatalysts under UV and visible light.

Functionalized graphene oxide- DMF dispersion

Product Description

Functionalized graphene oxide- DMF dispersion

For various solution processing based applications, graphite is chemically exfoliated into graphene oxide (GO) and subjected to appropriate functionalization. GO exhibits considerably stable dispersion in water. However, the stability of GO and functionalized GO (FGO) in organic solvents is often not satisfactory. Even in the commercial arena, organic dispersion with above 1 mg/mL is limited and often added with surfactants for stability, which decreased the recovery of conductivity upon reduction or heating. Because of 15 years research experience on the field, our researchers able achieve organic dispersion of graphene oxide up to 2 wt. % in polar aprotic solvents such as DMF, DMAc and DMSO and NMP, etc. Our FGO dispersions are stable for years. Further details can be found in specific information sheet.

PVDF based functional membranes

Details can be found in specific information sheet

Hydrophobic Ag NPs

Ag NPs are good option forming electrodes for flexible electronics. We have also expertise in the field of synthesis of conducting metal Nanomaterials such as Ag nanoparticles (Ag NPs) and formulation of Ag NPS based electronic printing inks. We are currently producing Ag NPs - Toluene dispersion, Ag NPs - limonene dispersion. The films patterns formed out our Ag NPs dispersion can yield metallic conductivity. Our dispersion suitable for forming films by dip coating, spin coating, plate and screen printing. Further details will be updated soon.

Hydrophilic Ag NPs

Water based Ag NPs dispersions, pastes, coating formulation is found application in various fields including electronics, antibacterial surfaces, and doping photocatalysts. Our Ag NPs silver dispersions and formulation can be used for above applications. Further details will be updated soon.

Substrate immobilized TiO2 photocatalysts

TiO2 photocatalysis is known to be capable of mineralizing all kinds of organic compounds and disinfecting mammalian viruses including SARS-CoV-2, gram-negative and gram-positive bacteria, bacteriophages, algae, protozoa, and filamentous and unicellular fungi. The use of TiO2 based NPs powder for water disinfection provide higher active surface area, thereby higher photocatalytic efficiency, they pose severe challenges in separation and reuse. For effective usage TiO2 based NPs must be immobilized on suitable substrate. Currently we are preparing TiO2 coated polymeric sheets and Stainless Mesh. Further details will be updated soon.

Custom synthesis of organic compounds>

With the help active guidance and suggestions of Dr. P. Ravichandran, we are also involved in the Custom synthesis of organic compounds. As applied research lead to industrialization, researchers from various academic background showing interest in functional applications. For example, the organic molecules with multi-functionality could be rationally applied in various areas such as drug candidates, chemical sensing platform and the benchmark materials for MOF synthesis. Therefore, custom synthesis of organic compounds is helpful for the researchers with purely from technical and engineering background. Upon request we can prepare but not limited to the flowing organic compounds.

Photocatalysis Testing Services

Dr. Ram is having 10 years research experience in the field of environmental photocatalysis. Due to the interdisciplinary nature of the field, to avoid any false positive results, the services of experts is required for assessing the efficiency of newly synthesized photocatalysts. We can test both powder and coasting type photocatalysts against UV and visible light sources. We can work any target pollutants including dye, pesticide and pharmaceuticals etc. The concentration of targets will be monitored using UV spectrophotometer.
