These theories are based on different hypothesis about material behavior, and result in yield functions of different forms. Isotropic Yield Criteria For isotropic materials, plastic yielding depends only on the
The high energy density laser beam is used to illuminate the material to be cut so that the material is quickly heated up to the evaporation temperature, and the material is evaporated to form a hole. As the beam moves relatively to the workpiece, the hole continuously forms a slit with a...
In the 21st century, industrial pipelines include huge complexity that need composite mechanical structure to manage its structural integrity. Pipelines are subject to various forms Read More » May 30, 2025No Comments From Heat to Vibration: How Bellows Perform in the Oil Industry ...
More recently, it has been discovered that ionic-salt-doped HTL forms robust quasi-ohmic contact, demonstrating high photo-thermal-operational stability in these devices35,36. Subsequently, we also developed a bilayer-conducting-polymer architecture comprising a doped p-type poly[bis(4-phenyl)(2,4...
Pouch-cell assembly was performed with a semi-automated cell-manufacturing line (Media Tech. Co., Ltd), which comprises a Z-stacking machine for the cathode, anode and separator; grid-trim; ultrasonic welding for connection with Al (cathode) and Ni (anode) external tabs; packaging and vacuum...
For example, As(V) has a total of four existing forms as H3AsO4, H2AsO4−, HAsO42− and AsO43−, which dominate under the pH ranges of <2.0, 3.0–6.0, 7.0–11.0 and > 12.0, respectively (Fig. 1b). Unlike the neutral form of As(V), three latter species are more ...

Form-stable paraffin-high density polyethylene-based phase-change material containing intumescent flame retardant and metal with high thermal conductivity, and its preparation method.Hu, YuanZhang, PingSong, Lei
[25]. This is possible because the use of different center metal ions forms a wide variety of MOF compounds with different organic ligands. As such, the number of possible combination of MOFs is enormous [26]. Various kinds of MOF application are under intensive studies and those include ...
