We consider two series of experimental setups of multilayered Ag/ZnO thin films with varying surface morphologies given by atomic force microscopy images. The absorption loss under diffuse scattering is studied theoretically by applying a combination of the scattering matrix approach with diffraction theory for randomly nanotextured interfaces. Our modeling is in excellent agreement with the respective measurements. The theoretical approach is applicable to a wide range of wavelengths, surface morphologies, and materials for both measured and computed rough surface morphologies.

Micro- and nanomorphological modification and roughening of titanium implant surfaces can enhance osseointegration; however, the optimal morphology remains unclear. Laser processing of implant surfaces has demonstrated significant potential due to its precision, controllability, and environmental friendliness. Femtosecond lasers, through precise optimization of processing parameters, can modify the surface of any solid material to generate micro- and nanomorphologies of varying scales and roughness.

Purpose: To investigate the presence of uridine-5'-triphosphate (UTP)-activated P2Y1-like nucleotide receptors (P2Y2R, P2Y4R, and P2Y6R) in conjunctival goblet cells (CGCs) and determine if they increase intracellular Ca2+ concentration ([Ca2+]i) and induce mucin secretion.
Methods: Adult, male rat conjunctiva was used for culture of CGCs. To investigate the expression of P2YRs, mRNA was extracted from CGCs and used for reverse transcription PCR (RT-PCR) with commercially obtained primers specific to P2Y2R, P2Y4R, and P2Y6R.

Plant extracts and bacterial biofilm are acknowledged to offer impressive corrosion-inhibitory activities. However, anticorrosive properties of their combination are still less reported. Thus, in the present study, we aimed to evaluate the corrosion inhibition efficiency of Saccharum officinarum bagasse (SOB) plant extract, Pseudomonas chlororaphis (P.

In polymerization-induced phase separation, the impact of polymer-substrate interaction on the dynamics of phase separation for polymer blends is important in determining the final morphology and properties of polymer materials as the surface can act as another driving force for phase separation other than polymerization. We modify the previously-developed polymerizing Cahn-Hilliard (pCH) method by adding a surface potential to model the phase separation behavior of a mixture of two species independently undergoing linear step-growth polymerization in the presence of a surface. In our approach, we explicitly model polydispersity by separately considering different molecular-weight components with their own respective diffusion constants, and with the surface potential preferentially acting on only one species.

DNA nanostructures (DNs) have gained popularity in various biomedical applications due to their unique properties, including structural programmability, ease of synthesis and functionalization, and low cytotoxicity. Effective utilization of DNs in biomedical applications requires a fundamental understanding of their interactions with living cells and the mechanics of cellular uptake. Current knowledge primarily focuses on how the physicochemical properties of DNs, such as mass, shape, size, and surface functionalization, affect uptake efficacy.
