3c). Taking the negatively charged wall of the microchannel as an example, when the liquid contacts the negatively charged wall of the microchannel, the cations in the liquid gather on the wall of the microchannel to form a thin electric double layer (EDL) (0.1 nm-10 nm). Under the ...
Abbreviations: PDMS, poly-dimethyl siloxane; PBMA, poly N-butyl methacrylate; PDMA, poly decyl methacrylate; PMMA, poly methyl methacrylate; PMAA, poly N-methyl acrylamide; PP, polypropylene; PP/PE, polypropylene polyethylene co-polymer; PTFE, polytetrafluoroethylene; PA, polyamide (nylon); PS, ...
Other materials for the intestine-on-a-chip typically include PMMA, PS, and PC. The material of the porous membrane can be selected from PDMS, PC, PET, and nylon, with pore sizes ranging from 0.01 μm to 10 μm. Methods for chip fabrication PDMS chips are commonly fabricated using soft...
Design and fabrication of 3DHSP. A Components of the 3DHSP, a hanging dripper, and a spheroid separation plate. The hanging dripper was 3D-printed, while the separation plate was fabricated by the assembly of poly (methyl methacrylate) (PMMA) and polydimethylsiloxane (PDMS) layers with hole ...
Schematic illustration of cascaded metasurfaces based perfect HDPBs for optical encryption. The plaintext is encrypted into two cascaded metasurfaces with multiple cells. According to the customized keys in the form of coordinates (x1,y1,x2,y2) of two arrayed metasurfaces, cascading two specific ...
To simultaneously maintain low absorption and high efficiency, we have devised a vertical truncated wavelength structure as our meta-atom. This meta-atom assumes the form of a cuboid with specific dimensions: height (H), length (L), width (W), and a lattice constant (P), as illustrated in...
Polymethylmethacrylate (PMMA) bone cement is used in orthopedics and dentistry to get primary fixation to bone but doesn’t provide a mechanically and biologically stable bone interface. Therefore, there was a great demand to improve the properties of the PMMA bone cement to reduce its clinical us...
Methyl methacrylate (MMA) serves as a fundamental component in the synthesis of poly(methyl methacrylate) (PMMA), a material extensively utilized across a wide array of industries such as furniture, drug delivery systems, and the fabrication of dentures [3]. However, traditional chemical processes ...
We introduce a technique that allows us to accurately mill the PMMA framework with the Ti Bases outside the mouth and then deliver it to the patient. This technique uses a series of scans performed during the surgical procedure, which are then superimposed on software.Aqeel Reshamvala...
Zhao[Citation41] developed a simpler form of the bending moment factor that is accurate for thick and stiff adherends but has limitations for short overlaps. After the determination of the loads at the ends of the overlap, Goland and Reissner[Citation16] calculated the shear and peel stresses ...
