Atomic layer deposition (ALD) is based on self-limiting surface reactions. This and cyclic process enable the growth of conformal thin films with precise thickness control sharp interfaces. A multilayered film, which nanolaminate, can be grown using ALD tuneable electrical optical properties to exploited, for example, in microelectromechanical systems. In this work, tunability residual stress, adhesion, mechanical nanolaminates composed aluminum oxide (Al2O3) titanium dioxide (TiO2) silicon...

The Compendium of Materia Medica highlights the therapeutic properties Trypoxylus dichotomus (T. dichotomus). In this study, species and content volatile components, inorganic elements, amino acids were measured, activity crude extracts ethanol water was studied. GC-MS analysis revealed 37-53 components across different life stages, excluding excessive heavy metals containing essential trace elements. Amino acid profiling identified 15 types, rich in seven medicinal varieties. vitro...

Abstract As a typical representative of Metastable intermolecular composites (MICs), the energy release nano‐thermites relying on aluminum‐oxygen reaction is limited by formation high boiling point condensed phase products. Low pressure output performance constitutes another pivotal factor influencing their efficacy. In this work, metal fluorides BiF 3 at different scales were incorporated into as oxidants, thereby facilitating tunability released energy. The points all resultant products...

The central question of this paper is how to simply enhance a set given supervised learning algorithms under some fairness requirements, ensure that any sensitive variable does not “unfairly” influence the outcome. To achieve goal, we work with several notions (Demographic Parity, Equalized Odds, Lack Disparate Mistreatment), possibly generalised more general concepts conditional fairness. We linearly combine an ensemble binary and/or continuous basis classifiers or regressors build...

The investigation of mechanical properties atomic layer deposition HfO2 films is important for implementing these layers in microdevices. change as a function composition and structure, which accordingly vary with temperature post-annealing. This work describes elastic modulus, hardness, wear resistance as-grown annealed HfO2. From nanoindentation measurements, the modulus hardness remained relatively stable range 163–165 GPa 8.3–9.7 temperature. annealing caused significant increase up to...

The use of thin-films made by atomic layer deposition (ALD) is increasing in the field optical sensing. ALD TiO2 has been widely characterized for its physical and properties, but systematic information about influence thermal history to mechanical properties film lacking. Optical applications require planar surface tunability refractive index residual stress. In addition, such as elastic modulus hardness performance layer, especially, when optics integrated with microelectromechanical...

Since copper azide (Cu(N3)2) has high electrostatic sensitivity and is difficult to be practically applied, silicon-based Cu(N3)2@carbon nanotubes (CNTs) composite energetic films with higher safety were fabricated, which can compatible micro-electro mechanical systems (MEMS). First, a porous alumina film was prepared by modified two-step anodic oxidation method. Next, CNTs grown in pores of the chemical vapor deposition. Then, nanoparticles deposited electrochemical deposition oxidized...
