Open AccessTowards a comprehensive characterization of spatio-temporal dependence of light-induced electromagnetic forces in dielectric liquids
The interaction of localized light with matter generates optical electrostriction within dielectric fluids, leading to a discernible change in the refractive index of the medium according to the excitation’s l...

Effect of the Slide-to-Roll Ratio and the Contact Kinematics on the Elastohydrodynamic Friction in Diamond-Like-Carbon Contacts with Different Wetting Behaviours
In this paper, we show how the slide-to-roll ratio (SRR), the contact kinematics and the surface energy all have important effects on the elastohydrodynamic friction. As reported previously, diamond-like-carbo...

The Formation of Tribofilms of MoS2 Nanotubes on Steel and DLC-Coated Surfaces
Solid-lubricant nanoparticles as additives in oil provide good tribological properties based on the physical lubrication mechanisms in the contact. For this reason, they are strong candidates for use in the lu...

Various MoS2-, WS2- and C-Based Micro- and Nanoparticles in Boundary Lubrication
Various solid lubricant particles have been experimentally evaluated as possible additives to oils. However, information in terms of a direct comparison of their tribological properties is still missing. In t...

Fatty Acid Adsorption on Several DLC Coatings Studied by Neutron Reflectometry
The application of diamond-like carbon (DLC) coatings on the contacts of mechanical systems is becoming widespread thanks to their excellent tribological properties. Numerous studies of DLC coatings have been ...

The Effect of Wetting and Surface Energy on the Friction and Slip in Oil-Lubricated Contacts
This work shows the influence of solid–liquid interactions between engineering surfaces (steel and several types of DLC coatings) and lubricating oil (polyalphaolefin, PAO) on the coefficient of friction in th...

Long-term treatment of invasive sinus, tracheobroncheal, pulmonary and intracerebral aspergillosis in acute lymphoblastic leukaemia
A 59-year-old male with acute lymphoblastic leukemia developed sinus, tracheobroncheal, pulmonary, and intracerebral aspergillosis. All lesions except the intracerebral aspergillosis healed after combination a...

Review of boundary lubrication mechanisms of DLC coatings used in mechanical applications
In the last ten years significant progress has been made on development and understanding of diamond-like carbon coatings (DLC), which enabled them to become one of the most promising types of protective coati...

The Effect of Do** Elements and Oil Additives on the Tribological Performance of Boundary-Lubricated DLC/DLC Contacts
In the past decade the range of possible applications for diamond-like carbon (DLC) coatings has changed significantly: from their conventional use in low-stress applications without lubricants, to their use i...

Influence of Mechanical Pressure and Temperature on the Chemical Interaction Between Steel and Silicon Nitride Ceramics
The chemical interaction between a Si3N4 ceramic, with Al2O3 and MgO sintering additives, and DIN 100Cr6 steel was studied by means of static interaction couple experiments between 500 and 1200 °C. At 500 °C, the...

Limnological Fundamentals of Acid Mining Lakes
Acidic mining lakes are clearly different from softwater lakes that have been acidified by aerial deposition, but despite their unusual ecosystems, they have attracted little scientific interest in the past. T...

Introduction
An even dimensional real vector space V is called symplectic if on V we have a skew-symmetric and non-degeneate bilinear form ω. More precisely, we say that ω is non-degenerate if ω(x,y) = 0 for all y ∈ V implies...

Gromov’s Compactness Theorem from a Geometrical Point of View
As a complement to the chapter on pseudoholmorphic curves we draw now our attention to the original proof of Gromov’s compactness theorem [50]. Pansu was the first to shed light on the ideas of this proof in h...
