Functionalized surfaces and surface functionalization of nanomaterials

, 2006
Nature leads, we follow. But nanotechnologists are in hot pursuit, in designing controllable structures that can mimic naturally occurring and artificially synthesized materials on a common platform. The supramolecular chemistry concerns the investigation of nature principles to produce fascinating complexed and functional molecular assemblies, as well

Finite size effects in adsorption of helium mixtures by alkali substrates

, 2003
We investigate the behavior of mixed 3He-4He droplets on alkali surfaces at zero temperature, within the frame of Finite Range Density Functional theory. The properties of one single 3He atom on 4He_N4 droplets on different alkali surfaces are addressed,

Function‐driven design of a surrogate interleukin‐2 receptor ligand

FEBS Letters, EarlyView.
Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in

Tribological manufacturing of ZDDP tribofilms functionalised by graphene nanoplatelets

JPhys Materials
3D Tribo-Nanoprinting (3D TNP), which uses a highly controllable tribological contact to deposit tribofilms, has been proposed as a manufacturing method for nanoscale structures.

Plasmon-Assisted Direction- and Polarization-Sensitive Organic Thin-Film Detector

Nanomaterials, 2020
Utilizing Bragg surface plasmon polaritons (SPPs) on metal nanostructures for the use in optical devices has been intensively investigated in recent years. Here, we demonstrate the integration of nanostructured metal electrodes into an ITO-free thin film

Subharmonic Functions and Minimal Surfaces [PDF]

Transactions of the American Mathematical Society, 1933
If (1) holds, y(u, v) is said to be the conjugate harmonic function of x(u, v), or if (3) holds, x(u, v) is said to be the conjugate harmonic function of y(u, v); generally, if (2) holds then x(u, v), y(u, v) will be called a couple of conjugate harmonic functions. 0.2. Generalizing this situation to the case of three functions x(u, v), y(u, v), z(u, v)

Time after time – circadian clocks through the lens of oscillator theory

FEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Self‐Healing Functional Surfaces

Advanced Materials Interfaces, 2018
AbstractDuring the last decade extensive research has focused on designing functional surfaces, e.g., with self‐cleaning, antibacterial, or antifouling properties, driven by the industrial demand on innovation and sustainability, and the academic interest in new functional materials.

Suppression of material transfer at contacting surfaces: The effect of adsorbates on Al/TiN and Cu/diamond interfaces from first-principles calculations

, 2017
The effect of monolayers of oxygen (O) and hydrogen (H) on the possibility of material transfer at aluminium/titanium nitride (Al/TiN) and copper/diamond (Cu/C$_{\text{dia}}$) interfaces, respectively, were investigated within the framework of density ...

Conserved structural motifs in PAS, LOV, and CRY proteins regulate circadian rhythms and are therapeutic targets

FEBS Letters, EarlyView.
Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.
