2020年1月21日 · The size and shape of the nanoplatelets provide barrier properties and the graphene component makes them excellent conductors. When exfoliated graphene nanoplatelets are added to polymers, they add electrical and thermal conductivity, reduce gas permeability, and improve mechanical properties, such as tensile strength and surface hardness.

2023年2月1日 · Covering growth mechanisms, we explain how a thorough understanding of nanoplatelet growth has enabled the development of nanoplatelets and heterostructured nanoplatelets with multiple emission colors, spatially localized excitations, narrow emission, and high quantum yields over a wide spectral range.

Exfoliated graphite nano-platelets (xGnP) are new types of nanoparticles made from graphite. [1][2][3][4] These nanoparticles consist of small stacks of graphene that are 1 to 15 nanometers thick, with diameters ranging from sub-micrometre to 100 micrometres.

1 天前 · Two-dimensional (2D) materials have revolutionized all areas of development of high-performance electronic devices. In particular, the unique electronic and optical properties of II–VI semiconductor nanoplatelets have been found to be very promising for optoelectronics. However, not all properties of this intriguing class of materials are yet known. A new, previously unknown hexagonal 2D ...

2025年2月3日 · Two-dimensional (2D) CdS nanoplatelets (NPLs) have attracted much attention due to their sharp absorption peaks and unique optical properties, but their formation mechanism has not been clearly exp...

2022年10月12日 · We demonstrate that the rich phase behaviour of nanoplatelets, and its sensitivity to subtle changes in shape and interaction potential can be used to guide the self-assembly into a wide range of...

2024年3月1日 · Here we show the nano-structural transformation of mesoporous-silica-coated Au-M (Ag, Pd, Pt) core-shell nanoplatelets (NPLs) with a triangular shape to alloyed platelets at temperatures at least 300 °C below the lowest melting point of the metals while still retaining the out-of-equilibrium triangular shape and intact mesoporous shell.

2 天之前 · This study explored the synergistic role of graphene nanoplatelets (GNPs) and carbon nanofibers (CNFs) on the thermomechanical fatigue performance of modified glass fiber-reinforced polymer (GFRP). Three composite materials were investigated including unmodified GFRP, GFRP modified with GNPs (0.75 wt% GNPs), and GFRP modified with hybrid nano ...

1 天前 · Figure 1c presents an SEM image of the composite sheet depicted in Fig. 1b. The image shows that GNPs can be effectively adsorbed onto the surface of the composite sheet while in a folded configuration. Figure 1d presents the Raman spectra of the GNPs on GNPs-AZ31, both prior to and following ultrasonic dispersion. The analysis reveals a reduction in the I G /I 2D ratio from an initial value ...

2022年1月12日 · Semi-conducting nanoplatelets are two-dimensional nanoparticles whose thickness is in the nanometer range and controlled at the atomic level. They have come up as a...
