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.
Plasma Treatment of PDMS leads to Improved Adhesion / Bonding
Plasma Treatment of PDMS for improved adhesion/bonding performance of microfluidic devices – new application note available now.
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.

Cirrus Plasma System – The effect of surface treatments on interfacial bonding
Researchers from the School of Engineering at the University of Edinburgh have recently published an article that 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.
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.
Examination of Effectiveness of Henniker Plasma Cleaner using a Holey Carbon Film by TEM
This work shows the effectiveness of the plasma treatment capability of the Henniker Plasma cleaner at different times and power levels.
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”.
