Abstract Contact line pinning and the corresponding contact angle hysteresis (CAH) are important interfacial phenomena that occur in nature and play a significant role in many industrial processes, such as surface coating, ink-jet printing, and immersion lithography. Traditional optical methods face limitations due to the optical diffraction limit, making it difficult to directly measure flow and interface phenomena at the micro- or nanoscale. However, atomic force microscopy (AFM) offers a solution by enabling precise manipulation and force measurements at micro and nano scales. The AFM-based microrheometer, which is assembled with a long-needle probe, can be used More >

Abstract The adsorption method has the advantages of low cost, high efficiency, and environmental friendliness in treating fluorinated wastewater, and the adsorbent material is the key. This study combines the inherent anion-exchange adsorption properties of layered double hydroxides (LDHs). Self-supported porous adsorbent materials loaded with AFm and AFt were prepared from a composite cementitious system consisting of calcium aluminate cement (CAC) and flue gas desulfurization gypsum (FGDG) by chemical foaming technique. The mineral composition of the adsorbent material was characterized by X-ray diffraction (XRD) and Scanning electron microscopy (SEM). Through the static adsorption experiment, the adsorption… More > Graphic Abstract

Abstract “How can we measure interface phenomena on the microscopic level” is a fundamental question that has been with us for many years and is also listed in recent Science 125 question. It is even harder to explore the electrified interface. In this work, we report atomic-force-microscope measurements of interfacial dynamics of an electrified room-temperature ionic liquid (RTIL)-solid interface. RTILs are intriguing fluids that have drawn much attention in applications ranging from tribology and catalysis to energy storage. With strong electrostatic interaction between ions, their interfacial behaviors can be modulated by controlling energetics of the electrified… More >

Abstract In this paper, we present a new modification of the newly developed semi-analytical method named the Optimal Auxilary Function Method (OAFM) for fractional-order equations using the Caputo operator, which is named FOAFM. The mathematical theory of FOAFM is presented and the effectiveness of this method is proven by using it with well-known Fornberg-Whitham Equations (FWE). The FOAFM results are compared with other method results along with their exact solutions with the help of tables and plots to prove the validity of FOAFM. A rapidly convergent series solution is obtained from FOAFM and is validated by… More >

Abstract Changes in cell-cell and cell-substrate adhesion markers are increasingly used to characterize disease onset and progression. However, these relationships depend on both the biochemical and molecular association between cells and between cells and their extracellular matrix, as well as the biophysical and mechanical properties orchestrated by cytoskeletal, membrane and matrix components. To fully appreciate the role of cell adhesion when determining normal physiology and the impact of disease on cellular function, it is important to consider both biochemical and biophysical attributes of the system being investigated. In this short viewpoint we reflect on our experiences More >

Abstract Deformability is a fundamental property of the cells and tissues of living organisms, which is commonly detected to indicate the state of the cells. And the cell deformability usually depends on the methods that we used, which is easy to be confused. The present research is designed to explore the energy characteristic of red blood cell deformability, based on a quantitative analysis of extending-retracting curves acquired from atomic force microscopy. ATP-depleted red blood cells are prepared by treatment with free-glucose Ringer solution. Our results clearly show that the Youngs’ modulus of erythrocyte is closely depended… More >

Abstract The mechanical properties of single cells have been recently identified as the basis of an emerging approach in medical applications since they are closely related to the biological processes of cells and human health conditions. The problem in hand is how to measure mechanical properties in order to obtain them more accurately and applicably. Some of the cell’s properties such as elasticity module and adhesion have been measured before using various methods; nevertheless, comprehensive tests for two healthy and cancerous cells have not been performed simultaneously. As a Nanoscale device, AFM has been used for… More >

Abstract With the development of society and the exhaustion of fossil energy, researcher need to identify new alternative energy sources. Nuclear energy is a very good choice, but the key to the successful application of nuclear technology is determined primarily by the behavior of nuclear materials in reactors. Therefore, we studied the radiation performance of the fusion material reduced activation ferritic/martensitic (RAFM) steel. The main novelty of this paper are the statistical analysis of RAFM steel data sets through related statistical analysis and the formula derivation of the gradient descent method (GDM) which combines the gradient… More >

Abstract Vascular smooth muscle cells (VSMCs) play an important role in regulating blood flow and pressure by contracting and relaxing in response to a variety of mechanical stimuli. A fully differentiated and functional VSMC should have both the ability to contract and relax in response to environmental stimuli. In addition, it should have the proper mechanical properties to sustain the mechanically active vascular environment. Stem cells can differentiate towards VSMC lineages and so could be used as a potential treatment for vascular repair. However, few studies have assessed the time it takes for stems cells to… More >

Abstract In the work presented in this article surface chemical modifi cation was applied to ramie cellulose nanocrystals by grafting organic acid chlorides presenting different lengths of the aliphatic chain. The objective of this surface chemical treatment was to enhance the nonpolar nature of the grafted nanocrystals and improve their dispersibility in a nonpolar polymeric matrix. The occurrence of the chemical modifi cation was evaluated by Fourier transform infrared (FTIR) spectroscopy, the degree of crystallinity by X-ray diffraction, and the morphology by scanning electron microscopy with fi eld emission gun (FEG-SEM) and atomic force microscopy (AFM).
