It is well known that molecules confined very close to a surface arrange into molecular layers. Because solid-liquid interfaces are ubiquitous in the chemical, biological and physical sciences, it crucial develop methods easily access layers exploit their distinct properties by producing layered crystals. Here we report method based on crystallization ultra-thin puddles enabled gas blowing, which allows produce crystals with thickness down monolayer onto surface, making them directly...
Graphene is a highly desirable material for variety of applications; in the case nanocomposites, it can be functionalized and added as nanofiller to alter ultimate product properties, such tensile strength. However, often properties graphene location any chemical species, attached via different functionalization processes, are not known. Thus, necessarily understood why improvements performance achieved, which hinders rate development. Here, commercially available powder containing few-layer...
With a growing interest towards low batch-volume personalised medicines and continuous manufacturing of pharmaceuticals, the need for robust non-invasive quality control analytical methods is becoming increasingly important. Current for...
Abstract There is a pressing need for reliable, reproducible and accurate measurements of graphene’s properties, through international standards, to facilitate industrial growth. However, trustworthy verified standards require rigorous metrological studies, determining, quantifying reducing the sources measurement uncertainty. Towards this effort, we report procedure results an interlaboratory comparison (ILC) study, conducted under Versailles Project on Advanced Materials Standards. This...
Flake thickness is one of the defining properties graphene-related 2D materials (GR2Ms), and therefore requires reliable, accurate, reproducible measurements with well-understood uncertainties. This needed regardless production method or manufacturer because it important for all GR2M products to be globally comparable. An international interlaboratory comparison on graphene oxide flakes using atomic force microscopy has been completed in technical working area 41 versailles project advanced...
We introduce a combined process for the reduction of graphene oxide (GO) <italic>via</italic> vitamin C (ascorbic acid) and thermal annealing.
The formulation of paediatric medicines faces significant challenges to meet the requirements for safe and accurate administration, while maintaining a suitable taste. Multiparticulate formulations have strong potential address these because they combine dose flexibility with ease administration. Understanding stability multiparticulate over storage as function time environmental parameters, such humidity temperature, is important manage their commercialisation use. In this work, we expanded...
Graphene is an ideal material for biosensors due to the large surface area multiple bonding sites, high electrical conductivity allowing sensitivity, and tensile strength providing durability in fabricated sensor devices. For graphene be successful as a biosensing platform, selectivity must achieved through functionalization with specific chemical groups. However, device performance sensitivity still maintained after functionalization, which can challenging. We compare phenyl amine...
Thin layers of highly conductive graphitic carbon are deposited onto nickel‐plated steel substrates using a direct photothermal chemical vapor deposition (PTCVD) technique. The coated improve electrical properties (sheet resistance and interfacial contact [ICR]) compared with pristine steel, which makes it cost‐effective alternative to stainless for producers use in high‐end applications such as energy storage microelectronics. is found have ≈10% reduction sheet 200 times ICR (under...
