Observation of Electronic States on Si(111)-(7x7) through Short-Range Attractive Force with Noncontact Atomic Force Spectroscopy [PDF]
, 2004 We experimentally reveal that the short-range attractive force between a Si tip and a Si(111)-(7×7) surface is enhanced at specified bias voltages; we conduct force spectroscopy based on noncontact atomic force microscopy with changing bias voltage at a ...

Atomic Force Microscopy of Nanoparticles and Biological Cells [PDF]
, 2015 Nanoparticles are of great interest in science and industrial application. The high surface to volume ratio offer very distinct physical properties compared to their corresponding bulk material. One of the most powerful tools to investigate nanoparticles

In silico and in vitro exploration of a tyrosinase for biocatalytic production of catechols
FEBS Open Bio, EarlyView.Tyrosinase from Ralstonia pseudosolanacearum is a promising biocatalyst for producing valuable catechols from monophenol substrates. This tyrosinase is uniquely suited to this due to its high monophenolase : diphenolase ratio. We combined in silico docking and in vivo kinetic characterisation of this tyrosinase with 11 industrially relevant monophenols,

Influence of Alkali Ions on Tribological Properties of Silicon Surface [PDF]
, 2015 Tribological properties of surfaces (friction, adhesion and wear) provide challenging limitations to the design of reliable machines on the micro- and nanometer scale as the surface to volume area increases and volume, mass and inertia of the mobile ...

Adenosine triphosphate as a modulator of protein interactions and stability
FEBS Open Bio, EarlyView.ATP is best known as the cell's energy currency, but it also shapes how proteins fold, interact, aggregate and form biomolecular condensates. This review explains the emerging physical principles behind these effects, including weak binding to charged protein regions, magnesium‐dependent behaviour and concentration‐dependent control of protein ...

FEBS Open Bio, EarlyView.The brown marmorated stink bug, Halyomorpha halys, mainly secretes 4‐oxo‐(E)‐2‐hexenal, (E)‐2‐decenal, dodecane and tridecane, a mixture representative of that released by many heteropterans. We demonstrated that H. halys can synthesise these secretory components de novo using dietary glucose.

Influence of Thermal Fluctuation on Attractive and Repulsive Casimir Forces in Microsystem with Topological Insulator Material [PDF]
فیزیک کاربردی ایرانHere, we explore the sensitivity of the Casimir force between two topological insulator plates on thermal fluctuation using weak and strong magnetizations on the surface of plates via Lifshitz theory.
