摘要：Sintering inhibition of a catalyst at high temperatures is a challenge during heterogeneous catalysis. In this paper, we report that hexagonal boron nitride(h-BN) is an optimal material for anti-sintering γ-Al_(2)O_(3)-supported Pt nanoparticles(NPs) originating from the high thermal conductivity of h-BN. The high thermal conductivity of h-BN ensures maximal heat dissipation from Pt NPs to γ-Al_(2)O_(3),thereby causing both Ostwald ripening and particle coalescence of Pt NPs to be decelerated at elevated *** of Pt NP sintering is also shown in the reducible TiO^(2-)supported Pt NPs with the help of h-BN. The proposed anti-sintering strategy using thermal management is universal, providing new insight into the design of anti-sintering materials and structures for a wide range of applications in heterogeneous catalysis.

摘要：In order to make a 10 Gbit/s 2：1 half-rate multiplexer operate without external clocks, a 5 Gbit/s clock recovery （CR） circuit is needed to extract the desired clock from one input data. For the CR circuit, a 3-stage ring voltage-controlled oscillator （VCO） is employed to avoid an unreliable startup of a 2-stage VCO and a low oscillation frequency of a 4-stage VCO. A phase frequency detector （PFD） is used to expand the pull-in range to meet the wide tuning range of a VCO required by process-voltage-temperature （PVT） variation. SMIC 0. 18-μm CMOS technology is adopted and the core area is 170 μm ×270 μm. Measurements show that, under a 1.8 V supply voltage, it consumes only about 90 mW, and has an input sensitivity of less than 25 mV, an output single-ended swing of above 300 mV, a phase noise of - 114 dBc/Hz at 1 MHz offset and a pull-in range of 1 GHz.
