Flexible and wearable electromagnetic interference (EMI) shielding material is one of the current research focuses in field EMI shielding. In this work, for first time, WS2-carbon fiber (WS2-CF) composites are synthesized by implanting WS2, which has a multiphase structure large number defects, onto surface carbon (CF) using simple one-step hydrothermal method, applied to protect electronic devices from EMI. It found that performance WS2-CF significantly improved, especially those at S...
Engineering microwave absorption materials with in multiple bands and strong performance the C-band remains challenging to date.
Two-dimensional (2D) MoS<sub>2</sub>/graphene nanosheet (MoS<sub>2</sub>/GN) hybrids have been demonstrated to be promising microwave absorption (MA) materials due their unique chemical and physical properties as well rich impedance matching.
Forming solid solutions through cation substitution is an efficient way to improve the luminescence properties of Ce3+ or Eu2+ activated phosphors and even develop new ones, which badly needed for phosphor-converted white LEDs. Here, we report color tunable solution based on K2Al2B2O7 as a typical case demonstrate that, besides crystal field splitting 5d levels, centroid shift Stokes can be dominant in tuning excitation emission spectra well thermal stability phosphors, both were previously...
The core–shell structure Ni(OH) 2 @CNTs composite were synthesized by wet chemical method at low temperatures. assembled @CNTs//AC asymmetric supercapacitors demonstrate high energy density and long cyclic stability.
We report on the continuous-wave and tunable laser operation of a transparent Yb:YAG ceramic which is prepared by non-aqueous tape casting method with vacuum sintering at 1750 °C for 10 h.

In lasing experiment, end-pumped high-brightness 974 nm diode pump in fiber core 50 μm numerical aperture 0.22, results maximum output power 7.01 W slope efficiency 60.2% 1050 nm. A smooth curve from 1022 to 1058 achieved testing, revealing...
We demonstrated a diode-pumped-passively mode-locked laser based on specially designed composite YAG/Yb:YAG ceramic. Theoretical studies reveal that this medium was beneficial for reducing the thermal effect. obtained 1.35-ps pulses with maximum output power of 475 mW an semiconductor saturable absorber mirror at room temperature 22 °C. A 240 W further generated using master oscillator amplifier system ceramic as seeding oscillator.
Laser performance of a multilayer YAG/Yb:YAG composite ceramic fabricated by nonaqueous tape casting was demonstrated in diode-pumped three-mirror cavity. We obtained maximum continuous-wave output power 3.6 W at 1051 nm with an absorbed pump 20.1 W, corresponding to slope efficiency 28.6%.

Abstract Nd:YAG transparent ceramics with different doping concentrations were fabricated by a solid‐state reaction method and vacuum sintering. Powder mixture of α‐Al 2 O 3 , Y Nd doped tetraethoxysilane (TEOS) MgO sintered between 1500 o C 1750 to examine the densification behavior in ceramics. For high 5 at%Nd:YAG ceramics, sintering kinetics microstructure evolution mainly discussed. It is found that optimal temperature for 5.0 was at ∼1700 C, in‐line transmittance increased increase...
