Although catalysis is a popular explanation for tribopolymer generation, the interplay of catalysis, mechanochemistry, and electrostatic interactions remain incompletely understood. There is consensus, however, that the mechanisms for forming a frictional polymer in situ require at least three conditions: the presence of organics, a catalytically-active substrate, and shear between surfaces (i.e., sliding contacts). *
The formation of these highly lubricious tribofilms at low temperature from ambient hydrocarbon species is novel and of significant practical interest, given the simple requirements to activate the process. *
In their article “Stress- and Time-Dependent Formation of Self-Lubricating In Situ Carbon (SLIC) Films on Catalytically-Active Noble Alloys” Morgan R. Jones, Frank W. DelRio, Thomas E. Beechem, Anthony E. McDonald, Tomas F. Babuska, Michael T. Dugger, Michael Chandross, Nicolas Argibay and John F. Curry describe how low shear strength (30 MPa) organic films were grown in situ on Pt0.9Au0.1 surfaces via cyclic sliding contact in dry N2 with trace concentrations of ambient hydrocarbons. *
The nanocrystalline Pt0.9Au0.1 alloy (also termed a Pt-Au thin film in the article) used in their study is likely catalytically-active while exhibiting high hardness (~ 7 GPa) and exceptional wear resistance. *
They then continue to present a systematic investigation of the stress- and time-dependent film formation. *
Atomic force microscopy (AFM) was used to study the formation and growth of films at the nanoscale. *
The authors’ AFM experiments confirm the increase in surface coverage (volume) with pressure, but also highlight a transition from film growth to wear at a threshold contact pressure near 1.2 GPa. *
With time-dependent AFM experiments they demonstrate a sublinear increase in film volume with time, suggesting that the efficacy of the catalytic process decreased as the number of cycles increased. *
NANOSENSORS Diamond Coated PointProbe® Plus AFM probes of the DT-CONTR type were used for the nanoscale tribology experiments with Atomic Force Microscopy. *

Stress- and Time-Dependent Formation of Self-Lubricating In Situ Carbon (SLIC) Films on Catalytically-Active Noble Alloys: Tribofilm formation as a function of number of cycles as determined from the nanoscale experiments. (a) Intermittent-contact mode topography images (3 µm × 3 µm area) of the contact region at a contact pressure of 1.2 GPa after 0 cycles, 500 cycles, 1000 cycles, 2000 cycles, 3000 cycles, and 4000 cycles. (b) Tribofilm volume as a function of cycles for contact pressures up to 3.1 GPa. For all P, tribofilm volume increased asymptotically to a steady-state value at large numbers of cycles.

Soluble fibrin (SF) in blood consists of monomers lacking both fibrinopeptides A with a minor population in multimeric clusters. It is a substantial component of isolated fibrinogen (fg), which spontaneously self-assembles into protofibrils progressing to fibers at sub-physiologic temperatures, a process enhanced by adsorption to hydrophobic and some metal surfaces. *
In their article “Novel characteristics of soluble fibrin: hypercoagulability and acceleration of blood sedimentation rate mediated by its generation of erythrocyte-linked fibers” Dennis K. Galanakis, Anna Protopopova, Kao Li, Yingjie Yu, Tahmeena Ahmed, Lisa Senzel, Ryan Heslin, Mohamed Gouda, Jaseung Koo, John Weisel, Marilyn Manco-Johnson and Miriam Rafailovich mention how they employed topographic and lateral atomic force microscopy (AFM) scanning for imaging fg monomers and soluble polymers. Adsorption to polystyrene (PS) and to trioctylmethylamine (TOMA) coated silica wafers was used.
NANOSENSORS™ SuperSharpSilicon™SSS-SEIHR high resolution AFM probes (typical AFM tip radius of 2 nm, typical force constant 15 N/m, typical resonance frequency 130 kHz) were used for the atomic force microscopy (AFM) in tapping mode. *

NANOSENSORS™ SuperSharpSilicon™ High Resolution AFM Probes are designed for measurements with enhanced resolution of nanostructures and microroughnesses. They are realised by a unique AFM tip manufacturing process leading to a further improvement of the AFM tip sharpness with AFM tip radii typically as low as 2 nm.
NANOSENSORS™ SuperSharpSilicon™ AFM probes are available on four different AFM cantilever types covering non-contact, acoustic or tapping mode applications as well as force modulation techniques. They are also optionally available with a magnetic coating on the AFM tip. Please have a look at the overview below.
The AFM probes of the SuperSharpSilicon™ series have stayed popular among researchers ever since their introduction and have contributed to research results presented in many published papers. You will find some literature references below. These references are just random examples.

Due to their very small AFM tip radius all AFM probes of the SuperSharpSilicon™ AFM probe series need careful expert handling. The higher the aspect ratio and the smaller the tip radius of an AFM tip is the more it will be susceptible to electrostatic discharge (ESD) which can destroy the AFM tip. It is therefore important to always make sure to take all necessary precautions against electrostatic discharge (ESD) whenever you are handling these special AFM probes so that their high quality leads to the expected high resolution AFM images and the AFM tip doesn’t become damaged before it has been used. This can be achieved in the usual way by e.g. using an ESD-safe handling kit consisting of a dissipative mat, grounding wire, wrist band and helix cable with integrated safety resistors and ESD safe tweezers.
