Abstract Low thermal conductivity, compatible expansion coefficient, and good calcium—magnesium—aluminosilicate (CMAS) corrosion resistance are critical requirements of environmental barrier coatings for silicon-based ceramics. Rare earth silicates have been recognized as one the most promising coating candidates water vapor resistance. However, relatively high conductivity coefficient limit practical application. Inspired by entropy effect, a novel rare monosilicate solid solution (Ho 0.25...
Abstract Micro‐sized bismuth (Bi) is recognized for its high volumetric capacity and suitable working potential, making it a promising anode candidate sodium‐ion batteries (SIBs). However, substantial volume changes slow reaction kinetics during cycling detrimentally affects the SIB performance. Theoretical prediction uncovers previously unexplored favorable attribute that bonding between nitrogen within carbon coating Bi atoms facilitates Na + ingress into bulk, significantly enhancing...
Abstract Aerogels excel in thermal insulation due to their porous structure, but limited mechanical strength restricts broader applications. Thus, the development of aerogel composites for equipment/personnel against and hazards extreme environments necessitates more design paradigm. Herein, a novel double‐crosslinked polyimide composite (PIAC) with an organic–inorganic hybridization approach is prepared. This composite, incorporating amino‐modified SiO 2 nanoparticles reduce...
The performance of Li-ion battery depends on the temperature. Active liquid cooling system can keep temperature within an optimal range, but itself consumes energy. This paper reported experimental work thermal for module under different schemes. It was hoped that energy consumption could be reduced as much possible. Meanwhile, provide effective module. Two identical real modules including 18 cylindrical cells (with and without system) were manufactured validity comparison. 2 discharged at...
Rare earth (RE) silicate is one of the most promising environmental barrier coatings for silicon-based ceramics in gas turbine engines. However, CMAS corrosion becomes much more serious and critical challenge RE with increasing operating temperature. Therefore, it quite urgent to clarify mechanism high-temperature CMAS-induced degradation at relatively high temperatures. Herein, interaction between RE<sub>2</sub>SiO<sub>5</sub> up 1500<sup>o</sup>C was investigated by a novel in-situ...
Abstract Rare earth tantalates (RETaO 4 ), known for their exceptional thermomechanical properties, are promising candidates next‐generation thermal barrier coatings (TBCs). However, the role of rare (RE) species in CMAS (calcium‐magnesium‐aluminosilicate) corrosion behavior and mechanisms RETaO remains unclear, hindering design application as TBCs. This study employs a high‐throughput approach to systematically investigate (RE = Nd, Sm, Eu, Gd, Dy, Ho, Y, Er) at 1300 °C. Precise analysis...
This paper presents a high linearity and low noise mixer for millimeter-wave applications in 65-nm CMOS process. A noise-reduction transformer with harmonic suppression is utilized inserted between transconductance stage switch to improve the figure (NF). Benefitted from transformer-coupling cascode topology, can operate at supply voltage without sacrificing linearity. In addition, this topology provides great freedom choice of biases stage. Thus, performance be further improved by...
Due to its ability of breaking the double-fading effect experienced by passive intelligent reflecting surface (IRS), active IRS is evolving a potential technique for future 6 G wireless networks. To fully exploit amplifying gain achieved IRS, two high-rate methods, maximum-ratio-reflecting (MRR) and selective-ratio-reflecting (SRR), are presented, which motivated maximum ratio combining selective combining. Moreover, both MRR SRR in closed-form expressions. further improve rate,...

Then, optimal design transmit power IRS reflection matrix proposed for maximizing transceiver subject covertness constraint (i.e.,...
Metal-organic porous materials (MOPMs), represented by the famous metal–organic frameworks (MOFs), have attracted extensive attention in recent years. While MOFs are unstable nature, they constructed coordination bond with low energies (<30 kJ/mol). This work proposed a series of metallocene-based covalent polymers (CMOPPs). The obtained show incredible ability resistance to air, water, as well even high concentration HCl or NaOH. Additionally, CMOPPs possess specific surface area (SSA)...
