The most commonly asked question concerning plasma surface treatment is; How long does plasma treatment last?
In this ‘Let’s talk About…’ article we discuss the main factors that influence the lifetime of plasma surface treatments and explain how these factors can affect different materials.
Newly published article using the Henniker HPT-100 plasma system to assist with precise patterning of solar cells.
Researchers at the King Abdullah University of Science and Technology (KAUST) in Saudi Arabia have recently used a Henniker HPT-100 to aid in their efforts to fabricate indium tin oxide (ITO)-free ultra-lightweight organic solar cells through inkjet-printing whilst preserving high efficiencies.
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.
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.
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.
Plasma cleaning to improve coating & adhesion.
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.
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 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 - 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.

Researchers from the School of Engineering at the University of Edinburgh have recently published an article which included surface treatments on interfacial bonding using the Henniker Cirrus Atmospheric Plasma System.The results displayed a significant improvement in the alloys surface wettability and hydrophilic properties.
The EPIC Centre, built to serve the Electronics and Photonics industry, recently acquired an advanced plasma treatment system from UK based manufacturer Henniker Plasma, read the full press release below.
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.
This work shows the effectiveness of the plasma treatment capability of the Henniker Plasma cleaner at different times and power levels.
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”.
