In order to rationally design a bio-functional surface based on the adsorption of a His-tag antigen, three requirements have to be considered: the bio-recognition element, the driving forces for the adsorption process an...

Regarded as a kind of smart surfaces, metasurfaces can arbitrarily tailor the amplitude, phase, and polarization of light. Metasurfaces usually consist of subwavelength nanoantenna or nanoresonator arrays, which are deli...

Abstract A novel multifunctional bi-anisotropic omega metasurface (MS) that simultaneously supports polarization transformation in both reflection and transmission modes, as well as narrow bandpass transmission functiona...

Fluid transport on confined systems is a subject of theoretical and technological interest. For instance, remarkable high flow rates have been obtained in carbon nanochannels (CNs) which cannot be predicted by standard m...

Density functional theory (DFT) calculations were carried out on hydroxylated and solvated (H&S) Fe substrates. Fe (110) and (111) extended surfaces as well as clusters of 32 and 59 atoms, and a nanoparticle of 80 atoms ...

Water repellency related to organic matter (OM) of coatings along the earthworm burrows (EB) walls can facilitate preferential flow due to limiting the water exchange with the soil matrix. The objectives of this work wer...

Recently there is an increasing interest in complex optical fields with spatially inhomogeneous state of polarizations and optical singularities. Novel effects and phenomena have been predicted and observed for...

Three-dimensional (3D) printing is a new paradigm in customized manufacturing and allows the fabrication of complex optical components and metaphotonic structures that are difficult to realize via traditional methods. Co...

IntroductionSmoothing fMRI data prior to analysis is a fundamental and widely used technique to increase sensitivity. Unconstrained smoothing can also reduce the spatial specificity of the analysis by introducing artifac...

The trophic ecology of the aquatic insect fauna has been widely studied for the Northern temperate zone. However, the taxa originally classified within a given particular trophic group in temperate ecosystems, do not nec...

We find that for adsorbed terephthalic acid (TPA) molecules surface Sn alloying deactivates the Cu(001) surface by decoupling the adsorbed molecules from the substrate. This effect is investigated for the case of the 0.5...

This study investigates how four nano-additives, namely graphene, amine-functionalized graphene, hexagonal boron nitride (hBN), and multi-walled carbon nanotubes, affect the properties of polylactic acid (PLA) used in ma...

The earth pressure on rigid retaining wall considering model indeterminacy is focused. Based on the force equilibrium equations for sliding mass, the functional extreme-value isoperimetric model for earth pressure in the...

Delhi, one of the fastest-urbanising megacities in the Global South, has undergone severe fragmentation of blue-green spaces (BGS) over three decades, driving deterioration of urban ecosystem health through impervious-su...

Ureteral stent-associated urinary tract infections (UTIs) remain a significant clinical challenge, primarily due to bacterial adhesion and biofilm formation. To address this, we engineered a multifunctional antibacterial...

Abstract Two-dimensional (2D) semiconductors enable atomically thin channels and attractive electrostatics, but practical scaling increasingly hinges on gate-dielectric integration rather than channel performance. A key ...

Unmanned Aerial Systems (UAS) continue to grow in both popularity and utility within the national airspace system. The use of commercial UAS for civil inspection, specifically that of bridge structures, is becoming commo...

In this investigation, differently shaped and surface functionalized TiO2 anatase nanoparticles and human serum albumin (HSA) were selected to study protein- nanoparticles interaction both in a solution and on flat surfa...

Abstract Background Systemic antibiotic administration requires repeated dosing to maintain therapeutic plasma concentrations. Controlled drug delivery systems reduce the need for continuous systemic antibiotic use by en...

We show how a theory for electrocatalysis developed in our group can be combined with density-functional theory in order to obtain free-energy surfaces for electrochemical reactions. The combined theory is applied to the...

The structure and energetics of two types of oxygen-terminated diamond surfaces, the keto and ether configurations, were investigated by density functional theory. To explore OH generation, we studied the approach of a h...

Poly(N-acryloylmorpholine) (P(NAM))-based materials have been developed to prevent protein adhesion to surfaces due to their biocompatibility and protein-repellent properties. However, transferring the benefits of P(NAM)...

Metal-organic coordination networks self-assembled on surfaces have emerged as functional low-dimensional architectures with potential applications ranging from the fabrication of functional nanodevices to electrocatalys...

Upconversion luminescence (UCL) has great potential for highly sensitive biosensing due to its unique wavelength shift properties. The main limitation of UCL is its low quantum efficiency, which is typically compensated ...
