Soft robots attract research interests worldwide. However, its control remains challenging due to the difficulty in sensing and accurate modeling. In this paper, we propose a novel iterative learning model predictive control (ILMPC) method for soft bending actuators. The uniqueness of our approach is the ability to im…
Low-frequency vibration energy harvesting is becoming increasingly important for environmentally friendly and biomedical applications in order to power various wearable and implanted devices. In this paper, we propose the use of piezoelectric congruent LiNbO3(LN) single crystals, with an engineered bidomain structure,…
Hyperbolic polaritons in van der Waals materials and metamaterial heterostructures provide unprecedented control over light-matter interaction at extreme nanoscales. Here we propose a concept of type-I hyperbolic metasurface supporting highly-squeezed magnetic designer polaritons, which act as magnetic analogs of hype…
Reported are well-defined donor-acceptor alternating copolymers prepared using ring-opening metathesis polymerization (ROMP). Unsymmetrical cyclophanedienes comprising electron-donating (4-methoxy-1-(2-ethylhexyl)oxy)benzene (MEH) and electron-accepting benzothiadiazole (BT) rings were synthesized from the correspondi…
Abstract The deformation microstructures and the mechanical properties of an advanced austenitic stainless steel subjected to hot forging with a decrease in deformation temperature from 1,323 to 1,073 K were studied. The deformation microstructures were characterized by the development of dynamic recrystallization (DR…
Purpose This paper aims to investigate the parametric study of addition of snail shell particles (SSp) and bath temperature on the properties of Zn-ZnO-SSp composites coating. Design/methodology/approach Bath temperatures of 60°C and 90°C and SSp of 0, 5, 10, 15, 20 and 25g were used in the electrodeposition. The micr…
Тhere has been developed technology, and pilot batch of hot rolling coils (6×1500 mm, steel grade S355MC) has been produced using thermo-mechanical controlled process (TMCP) for the wide-strip rolling mill 1700. The integrated technology for TMCP coil production (steel grade S355MC) has been firstly developed for the…
Abstract Blasting is common activity used in quarry to fragment rock which the aim is to obtain maximum yield with desired fragmentation in a safer manner. This study has opened up new possibilities to optimize the blasting in order to achieve the desired fragmentation of rock. Discrete element method (DEM) and partic…
We describe Bayesian Model Optimized Reference Correction (BaMORC), a software package that performs 13 C chemical shifts reference correction for either assigned or unassigned peak lists derived from protein NMR spectra. BaMORC provides an intuitive command line interface that allows non-nuclear magnetic resonance (N…
Die casting process is widely applied in making Al parts. However, due to high speed of liquid metal flow in the die cavity, gases are prone to be entrapped in the filling, resulting in porosity defects. The X-ray computed tomography scanning technique was used to detect the pores in die-cast ADC12 alloys with differe…
Surface state (N-ss) density and their relaxation time (tau) of the fabricated Al/ZnO/p-GaAs structure was investigated in frequency range of 1 kHz-1 MHz and in voltage range of +/- 1.2 V. It was found that the variance of capacitance (C) and conductance (G/omega) with frequency and voltage is basically different espe…
This paper studies voltage stress in complex machine windings under steep-fronted voltage excitations from inverter drives. Electrical stress in this paper includes voltage overshoots between any two conductors in windings and between conductors and the stator. This stress can accelerate insulation degradation in inve…
Abstract Elevated temperature deformation of as-cast aluminum 7068 alloy was done to optimize its workability by physical simulation using Gleeble 3800. The microstructural evolution was traced using electron microscopy and electron back-scattered diffraction studies. Hot deformation involving uniaxial isothermal comp…
Purpose: To explore the effect of curcumin and low-frequency and low-intensity ultrasound (LFLIU) on C6 and U87 cell, and whether LFLIU could inhibit multidrug resistance protein 1 (MRP1) by increasing the sensitivity of curcumin via vascular epithelial growth factor (VEGF)/PI3K/Akt signaling pathway targeting. Method…
Bioactive glasses (BGs) are a group of surface-reactive biomaterials used in clinical applications as implants or filler materials in the human body to repair and replace diseased or damaged bone. Sol-gel technique was employed to prepare a SiO2-CaO-P2O5 glass with nominal composition of 58S BG with the addition of Sr…
Using the dependence of the activation energy of 4-alkyl-1,3-dioxane formation on the pore diameter of zeolites, the catalytic activity of the latter in the Prins reaction was theoretically explained. The stabilization of a prereaction π-complex in the cavities of a number of zeolites ( $${\text{Na}}_{x}^{ + }$$ (H2O)…
The reaction between a carbon crucible and Si-Cr solvent, and the carbon solubility at SiC saturation in Si-Cr solvent were investigated using infrared absorption after combustion, field-emission scanning electron microscopy, and electron probe microanalysis. Si0.6Cr0.4, commonly used for silicon carbide crystal growt…
The application of nanomaterials has been rapidly increasing during recent years. Inhalation exposure to nanoparticles (NP) may result in negative toxic effects but there is a critical lack of human studies, especially those related to possible DNA alterations. We analyzed pre-shift and post-shift a group of nanocompo…
The assessment of material deposition and fuel retention on Plasma Facing Components (PFCs) is of primary importance for the steady-state operations of future fusion devices.

Nowadays, the direct bonding process is embedded in a BEOL manufacturing process where the maximum temperature is 400°C. For certain applications there is the need to lower such thermal budget. One of the first process steps which will be modified will be the bonding layer deposition step as well as the densification…
