There is an urgent need for polymer composites with high thermal conductivity and electrical insulation in microelectronic packaging.Due to their fascinating chemical physical properties, multi-walled carbon nanotubes (MWCNTs) have enabled major achievements fields as a reinforcement filler.Nevertheless, of raw MWCNTs (R-MWCNTs) was obstacle wider application the CNTs some special fields, which require outstanding properties simultaneously.In this work, silica@MWCNTs were prepared reduce...
The Fe<sub>3</sub>O<sub>4</sub> nanospheres (Fe<sub>3</sub>O<sub>4</sub>-S) were controllably prepared for highly efficient degradation of tetracycline at neutral conditions.
Using sub-wavelength metallic gratings as both transparent electrodes and broadband high-efficiency polarizers, a highly-compact self-polarizing phase shifter is demonstrated by electrically tuning the effective birefringence of nematic liquid crystal cell. The metal grating polarizers ensure good polarizing efficiency in range 0.2 to 2 THz. Phase shift more than π/3 achieved 256 μm-thick cell with saturation root mean square voltage around 130 V this integrated device.
The polarization independence of liquid crystal gratings with alternate orthogonal aligned regions is theoritically studied and demonstrated by means photoalignment technique. different alignments in adjecent are achieved two-step photo exposure to guide orientations sulfonic azo dye layers further align the molecules. Both one-dimensional two-dimensional switchable phase have been demonstrated. Such polarizer-free show very high transmittance (∼92%), diffraction efficiency (over 31%),...
Hybrid graphene-metal gratings with tunable Fano resonance are proposed and theoretically investigated in THz band. The grating contains alternately aligned metal graphene stripes, which could be viewed as the superposition of two kinds same period. Due to different material properties, coupling between parts forms typical Fano-type transmitting spectra. related physical mechanism is studied by inspecting induced dipole moment local surface charge distributions at wavelengths. Both amplitude...
In this work, a self-powered system based on triboelectric-electromagnetic hybrid pipeline energy harvesting module is demonstrated. Rabbit fur and poly tetra fluoroethylene (PTFE) are used as triboelectric electrodes to fabricate disk-type soft-contact nanogenerators (TENGs) instead of traditional direct-contact TENGs collect the mechanical water flow convert it into electrical energy. This design has stable output gives an improved durability. Its simple fabrication process enables...
Magnetic microrobots have attracted increasing research interest for diverse biomedical applications, such as targeted therapy and tissue regeneration. However, multifunctional with complex morphology at the microscale are urgently needed to be fabricated, actively controlled, functionalized.

The optimal control of the heating, ventilation, and air-conditioning (HVAC) system in buildings has a significant energy saving potential therefore is great practical interest. An event-based HVAC adjusts actions when certain events occur, which may be faster more scalable than state-based or time-driven methods. However, capture either local global changes rooms. choice tradeoff between computational efficiency performance. This challenging problem remains open. We consider this as an...
Accurate and efficient surgical robotic tool pose estimation is of fundamental significance to downstream applications such as augmented reality (AR) in training learning-based autonomous manipulation. While significant advancements have been made for humans animals, it still a challenge robotics due the scarcity published data. The relatively large absolute error da Vinci end effector kinematics arduous calibration procedure make calibrated data collection expensive. Driven by this...
We propose and investigate a type of hybrid plasmonic waveguide in metal V-groove. A high-permittivity nanowire was placed the channel covered with dielectric film lower permittivity. Deeper sub-wavelength confinement much longer propagation distance were achieved comparison conventional waveguides. The overall performance improved as compared structure based on flat surface. Finite element analysis showed that both mode field profile can be adjusted by changing radius thickness. Some...
An efficient frequency conversion scheme of surface-plasmon polariton (SPP) is proposed for nonlinear plasmonic applications. Lossy coupling wave equations are deduced to describe the interaction among involved SPP components.
