Precious Metal Modified 2D Substrate
Since the discovery of mechanically exfoliated graphene, the development of two-dimensional (2D) materials composed of atomically thin crystal layers bound by van der Waals forces has accelerated due to the potential applications of these materials in optoelectronics, catalysis, new technologies, and electricity. 2D-MoS2 nanosheets are excellent layered materials with unique layered structures and large surface areas. It is important to study ways to improve the chemical properties of MoS2, which may affect its applications in electronic devices, catalysis, and molecular sensing.
Alfa Chemistry can provide you with a way to improve the performance of MoS2: decorate MoS2 with precious metal nanoparticles. For example, MoS2/precious metal nanoparticle composites can induce local surface plasmon resonance (LSPR), which is used to activate H2 photocatalysis and enhance the light absorption or emission of MoS2. In addition, LSPR can generate surface-enhanced Raman scattering (SERS), It can be used in biological and chemical sensing applications.
Self-Healing Vitreous Coating with Long-Lasting Hydrophobicity
Alfa Chemistry uses nano-thick, perfluorinated polydimethylsiloxane glass body to prove durable and super-hydrophobicity. The ultra-thin (less than 100 nm) polydimethylsiloxane glass body film we constructed maintains excellent hydrophobicity and light transmission after scratching, cutting, and indentation. We show that polydimethylsiloxane vitreous films can be deposited on various semiconductor substrates by scalable dip coating.
