Windows are the least energy efficient part of buildings, as building accounts for 40% global consumption. Traditional smart windows can only regulate solar transmission, while all on window is wasted. Here, first time, authors demonstrate an saving and generation integrated (ESEG window) in a simple way by combining louver structure cell, thermotropic hydrogel, indium tin oxides (ITO) glass. The ESEG achieve excellent optical properties with ≈90% luminous transmission ≈54% modulation, which...
High-performance hydrogen peroxide sensors provide valuable signals of biological interactions, disorders, and developing diseases. Low-cost metal oxides are promising alternatives but suffer from low conductivity sensing activity. Multi-component excellent candidates to accomplish these challenges, the composition inhomogeneity is difficult manage with conventional material preparation. We demonstrated redox preparation strategies successfully synthesize highly homogeneous, noble metal-free...
Waste water with heavy metal ions has been of great concern because its increased discharge, toxic and some other bad effects on human beings or the environment. In this article, monodispersed chitosan/silica hybrid microspheres porous structure large specific surface area were successfully prepared by using microfluidic technology they have advantages in mechanical property adsorption such as Cu(II). optimum condition, 1.0 wt.% TEOS dispersed phase pre-solidified for 3 h enhanced intensity,...
Recently, we developed highly fluorescent Ti3 C2 and Nb2 C Mxene quantum dots (QDs) for labeling of in vitro models. However, the mechanism toxicity prepared QDs was not explored before. In this study, addressed possible associated with cytotoxicity to human umbilical vein endothelial cells (HUVECs). Exposure up 100 μg/ml but 24 h significantly induced cytotoxicity. The exposure also increased intracellular Ti Nb elements, indicating internalization both types QDs. None promoted interleukin...
A novel microfluidic approach to measure interfacial tension of immiscible fluids rapidly is reported. This method rests upon quantitative force balance analysis drop formation dynamics in a coaxial device. The values for several two liquids without/with surfactants are measured. These measurements compare well with those measured by the commercial tensiometry. viscosity water phase fluid can also be accurately same Several model systems from 1.0 10.0 mN/m and mPa·s tested this work.
A novel and simple approach to prepare monodispersed chitosan microspheres with relative small size controlled structures was developed by combining the solidification methods of solvent extraction chemical crosslinking in a capillary-embedded microfluidic decive. The different are used field protein drug release immobilization lipases they show profiles good stability, respectively. Chitosan, obtained alkaline deacetylation chitin, which is second-most abundant polysaccharide next...
A level set method embedded in a Computational Fluidic Dynamics (CFD) simulation is useful approach the study of microfluidic two-phase flow. In this work, we established new governing equation for function to overcome "mass loss" problem. The feasibility modified was proved by droplet formation co-tube microchannel. then used simulate flow focusing shape results showed that size would decrease with an increase continuous phase rate. early stage process, there strong inner circulation...
This article describes a simple method for the fabrication of microscale polymer tubes. A double co-axial microchannel device was designed and fabricated. Liquid/liquid/liquid multiphase co-laminar flows were realized in by choosing working systems. Three kinds polymeric solutions selected as middle phase while polyethyleneglycol aqueous solution used inner outer phases microfluidic process. The acted extractants solvent. stable core-annular flow formed optimizing composition phases, highly...
The lack of experimental data for the droplet breakup has been one limitations application population balance model (PBM). In this work, a high‐speed camera was used to directly measure frequency and daughter size distribution in pulsed disc doughnut column. It found from captured video that multiple events were more frequently observed than binary breakup. treated as an original several intermediate breakups characterize process quantitatively. effects pulsation intensity, dispersed phase...
During oil recovery process, the equilibrium state of asphaltene–oil solution system and colloidal in porous media is altered, which could cause asphaltene to precipitate from crude rock pores. This severely results alteration wettability, permeability, porosity formation damages reservoir formation. Nanoparticles have recently been considered as effective inhibitors. Several experimental works were carried out study impact nanoparticles on precipitation. The majority these studies performed...
Abstract The method developed in our previous work (Wang et al., AIChE J . 2020; 66(8): e16257), was used to study the influence of mass‐transfer direction and flux on dynamic interfacial tension (DIFT) a pulsed column. breakup frequency highest near entrance dispersed droplet, corresponding lowest mass transfer flux. decrease proportional square root flux, this difference is defined as new parameter, named relaxation. When changed from phase continuous opposite direction, proportion binary...
Geckos have one of the world's most efficient reversible adhesion systems. Even walking in dusty conditions, geckos can dislodge up to 80% contaminants and recover their capability after as few four steps. Thus far, artificial dry self-cleaning materials inspired by geckos' hierarchical fibrillar structure been only able remove 55% collected large particle with 30 Challenges, including low mechanical strength, stiffness, short fatigue time keep these from being used practical applications....
Abstract The direct experimental data for breakup parameters of drop time, multiple breakage, and rate are urgently required to understand phenomena. In this regard, experiments were carried out in a stirred tank using high‐speed online camera. influences the rotating speed, interfacial tension, viscosity on above then quantitatively investigated.

In two‐phase dispersion coupling interphase mass transfer process, the variation of interfacial tension is an important factor affecting dispersion. this study, we described a microfluidic method for determination transient (TIFT). The has advantage determining TIFT during whole droplet formation rather than only at rupture moment as reported in previous studies. TIFTs several systems were determined. certain systems, it been found that size decreased with increase dispersed phase flow rate,...
