In-situ water layer thickness determination during accelerated corrosion testing

In-situ water layer thickness determination during accelerated corrosion testing

A collaboration of researchers at the University of Virginia, Sandia National Laboratories Albuquerque and Tohoku University Japan have recently published a paper that outlines the design, construction, and validation for in-situ water layer thickness determination during accelerated corrosion testing. In this work the Henniker HPT-100 was used to remove hydrocarbon contamination from the surface within the sensor in order to give a uniform for water layer, thereby creating an experimental system geometry that is directly comparable to the modelled geometry thickness determination.

Removal of carbon contamination prior to SEM & EDS measurement

Nano-devitrification and structural evolution of amorphous state in surface Ti-Ta-based alloy fabricated on TiNi substrate through additive thin-film electron-beam synthesis

Henniker’s HPT-100 was used in this work to remove carbon contamination on the sample’s surface before it was characterised by SEM and EDS measurements.

Let’s Talk About… Which vacuum pump should I choose?

Which vacuum pump should I choose?

Henniker Plasma’s range of vacuum plasma treatment systems (HPT and Nebula models) include a suitable vacuum pump which is required for the low pressures needed during plasma operation.

The Henniker HPT-100 benchtop plasma system is being put to good use within the Department of Polymer and Biomaterials Science at the West Pomeranian University of Technology, Szczecin (ZUT) where Dr Peter Sobolewski and his colleagues are working in the area of polymeric biomaterials.

Adhesion and Surface Energy Explained

There are a number of quick and simple tests to determine the effectiveness of a particular plasma process upon a surface.

Adhesion and surface energy test methods have the benefit of being applicable to both untreated and treated surfaces and so also provide a useful comparison before and after processing. Each test is effectively providing information about the surface energy of the material being tested. Before describing the various test methods it is therefore useful to review what we mean by surface energy. 

 

Oxygen Plasma Ashing for preparation of samples

Oxygen Plasma Ashing for successful preparation of samples - Stable isotope ratio measurements, performed by mass spectrometry, can provide accurate information in a number of geoscience applications, including the reconstruction of past glacial/interglacial temperature variations for example.

Preparation of nanoparticles prior to atomic force microscopy

Preparation of Nanoparticles - Recently published research in Nature Materials, by groups working at King Abdullah University of Science and Technology (KAUST), Imperial College London and the Rutherford Appleton Laboratory details advances in the development of organic semiconductor photocatalysts which could be used in solar panels to harness more of the sun’s energy than was previously possible.

Investigating the nanoscale adhesion mechanisms between polymeric biomaterials and biological samples

Recently published research from scientists at Queen Mary University of London and GlaxoSmithKline demonstrates the complex nature of nanoscale adhesion mechanisms between polymeric biomaterials and biological samples.  Henniker’s HPT-200 plasma system is used in this work to provide the clean substrate surfaces (silicon and gold) onto which a variety of polymer brushes and self-assembled monolayers (SAMs) were synthesized.

Application Highlight: Sample Plasma Cleaning for Microscopy

TEM Sample Plasma Cleaning

Below, we examine the effectiveness of a Henniker Plasma Cleaner for holey carbon grid preparation used in TEM/SEM Microscopy. The work, summarised here, was completed using our HPT-100 Plasma Cleaning System with our Jeol TEM sample holder adapter.

The Leidenfrost effect and superhydrophilic plasma coatings

Recently, thin-film boiling, via the Leidenfrost effect, has been demonstrated as a promising concept for converting thermal energy to mechanical motion. In this 2019 published paper, the authors address two key challenges users face when working with Leidenfrost heat engine levitating rotors and their sustained rotation. Their aim, “to provide new opportunities for novel approaches for heat to motion conversion in extreme environments”.

The National Physical Laboratory (NPL), is the UK’s National Measurement Institute and is a world-leading centre of excellence in developing and applying the most accurate measurement standards, science and technology available. Henniker’s Plasma Treatment equipment is being evaluated so it can be used in keeping the accuracy of the UK’s measurement standards.

Plasma cleaning for UHV applications: particle accelerators

Hyper-clean Surfaces

daresbury labs logo

UHV critical components, such as those used extensively in surface science laboratories and particle accelerators, are required to meet strict cleanliness criteria of which pre-installation cleaning is an important step. Daresbury Laboratory based in the UK and a centre for worldwide particle accelerator technology, approached Henniker Plasma to look at the potential of oxygen plasma cleaning as part of the stringent pre-cleaning process.
