模板剂合成ZSM-35动力学模拟计算

通过分子模拟途径,将吡咯烷、乙二胺、正丁胺三种有机模板剂与ZSM-35沸石骨架间非成键互作用的能学分析分别于它们的合成实验结果进行对照,论证模板剂与沸石间非键相互作用能与合成速率的关联。发现处于十员环孔道中的上述三种模板剂与ZSM-35骨架间非成键互作用能从小到大的顺序与晶化速率从快到慢的顺序一致。     

The Elastic Continuum Limit of the Tight Binding Model

The authors consider the simplest quantum mechanics model of solids,the tight binding model,and prove that in the continuum limit,the energy of tight binding model converges to that of the continuum elasticity model obtained using Cauchy-Born rule.The technique in this paper is based mainly on spectral perturbation theory for large matrices.     

Flat Top Optical Frequency Combs Based on a Single-Core Quantum Cascade Laser at Wavelength of ～8.7 μm

We present optical frequency combs with a spectral emission of 48 cm^-1and an output power of 420 m W based on a single-core quantum cascade laser at λ ～ 8.7μm. A flat top spectrum sustains up to 130 comb modes delivering ～ 3.2 m W of optical power per mode, making it a valuable tool for dual comb spectroscopy. The homogeneous gain medium, relying on a slightly diagonal bound-to-continuum structure, promises to provide a broad and stable gain for comb operating. Remarkably, the dispers...
