Spin Coating Hydrogel Films

Thin hydrogel films have attracted great attention due to their promising applications in molecular separation, medical dressings, flexible electronics, etc. The tough physical hydrogel films by spin coating of a P (acrylic acid-co-acrylamide) or P (AAc-co-NIPAm) polymer solution and a subsequent gelation process, in which robust carboxyl–Fe3+ coordination complexes
were formed.

By controlling the spin time, spin speed, and concentration of the polymer solution, the thickness of the films could be well tuned, ranging from several to hundreds of micrometers. The hydrogel films showed excellent mechanical properties, with tensile breaking strengths, breaking strains, Young’s moduli and tearing fracture energies. The obtained gel films showed a fast response (<60 s) and a large output force (~0.2 MPa) triggered by a concentrated saline solution, making them an ideal material in the design of chemomechanical device.

Spin Coating For Fabrication Of (r) GO-Assisted Membranes

Spin coating method is a widely used method for the fabrication of (r) GO-assisted membranes. Commonly, the first step of spin coating is dropping GO suspension on a base. The second step is rotating the plate with high speed. Consequently, there will be a formation of thin liquid layer which is driven by a centrifugal force. The properties of different GO membranes prepared by three methods, spin-coating, drop-coating and solvent-induced precipitation. They used glass and quartz as substrate to fabricate GO films. As a result, the GO films fabricated by spin coating were the thinnest among all products.

Spin coating method can easily adjust the thickness and area of membranes by controlling the amount of (r) GO solution and the size of the substrate. The produced r-GO thin film have been used in the application of photodetection.

The Checklist Of Scientific Laboratory Equipment

Not Surprisingly, there is an increasing focus on R&D in India that is generating demand for good quality scientific laboratory equipment and supplies. While this is good for the science community, this also augurs a positive future for the Indian job market. As research and development is bound to improve the overall competitiveness and productivity levels of Indian businesses, research institutes and students.

 

Scientific Laboratory Equipment: The Final Checklist

 

While India transforms itself into an innovation led economy, and the world becomes a larger stage to flex its economic muscle, there are a number of challenges to be addressed. And one of them is the lack of quality scientific laboratories in the country and of quality laboratory equipment. This challenge starts right from the laboratories at many schools and colleges across the country… where the study of science still relies heavily on conventional classrooms. Where for an innovation and job growth driven economy, there must be more involvement with physical handling of materials and real experiments. Because students without practical experience in the various branches of science will remain ineffective in fast developing real world scenarios.

 

What Good Scientific Laboratories Do

 

What Good Scientific Laboratories Do

For effective learning good schools and colleges invest in a healthy mix of classroom teaching with practical projects that encourage deep understanding in their students. And these students of science stand a better chance to find place in reputed research and development centers that invest in high quality equipment and teams to explore newer horizons.

So if your education institute has a science laboratory, it is important to invest in the latest and most advanced materials and supplies. This will not only make science interesting and effective for students, it will also lead to a fundamental change in your contributions to the various fields of science and the economy as a whole.
