Oriented NiAl-layered double hydroxide (LDH) films with micro-/nanometer scale binary structures are prepared by in situ crystallization, without using any external aluminum source or shape-directing surfactant, on a porous anodic alumina/aluminum substrate. The NiAl-LDH film can be controlled tuning crystallization temperature and time. Facile hydrophobic modification of the surface leads to superhydrophobicity, as shown figure.
Apart from single hemostasis, antibacterial and other functionalities are also desirable for hemostatic materials to meet clinical needs. Cationic have attracted great interest antibacterial/hemostatic applications, it is still explore rational structure design address the challenges in balanced hemostatic/antibacterial/biocompatible properties. In this work, a series of cationic microspheres (QMS) were prepared by facile surface modification microporous starch with tannic acid derivate,...
Traditional hemostatic materials often fall short of meeting clinical demands in terms both hemostasis and antibacterial efficiency. The use cationic the fields has garnered significant attention. However, designing that effectively balance these two properties remains a critical challenge development materials. In this context, dual-functional hydrogel (F-QMS-OX) was developed by incorporating starch microparticles (QMS) ofloxacin into thermosensitive poloxamer with optimized loading...
The polypropylene (PP) blending ultrafine fibres with self-made melt differential electrospinning apparatus and hydrophilic modification of the were produced in present study. Two different agents, as additives coating respectively, mixed PP, mixtures spun under same spinning conditions. In addition, effect methods was studied. results show that method can produce mass considerable production efficiency (effective output is ∼9 g h−1), diameters mainly range from 2 to 6 μm. after adding or...

Following a similar idea as described in Part I of this paper, the redundant bending moment and shearing force at junctures hemispherical/cylindrical shells cylindrical different thicknesses are shown to be unique functions λ (ratio thickness joint members) η shell its mean diameter). Thereby, simplification calculation for is proposed demonstrated possess good accuracy.
Results from finite element analysis were used to show that the stress index kσ and nondimensionalized highly stressed hub length kh of a flat head with round corner in pressure vessel subjected internal are functions three dimensionless parameters: λ ≡ h/dt, η t/d, ρ r/t. Approximate formulas for estimating λ, η, p given. The can be determining suitable fillet radius order reduce fabricating cost keep intensity at under an acceptable limit.
