前言化学交联结构对弹性体材料力学性能的影响,经长期的研究,有大量的报告。对交联结沟与拉伸强度的相互关系,出现了截然相反的观点。在硫黄促进剂体系中,伴随着硫化反应,有大量的复杂反应,生成各类型的单硫醚、双硫醚和多硫醚交联的主... 详细信息

前言化学交联结构对弹性体材料力学性能的影响,经长期的研究,有大量的报告。对交联结沟与拉伸强度的相互关系,出现了截然相反的观点。在硫黄促进剂体系中,伴随着硫化反应,有大量的复杂反应,生成各类型的单硫醚、双硫醚和多硫醚交联的主链异构结构。这些复杂的反应及随之生成的网络结构取决于硫化体系及其硫化条件。阐明硫化胶中真正的交联结构是极其重要的。

＜正＞聚磷腈是结构可调的聚合物,在生物医药领域（例如药物输送、组织工程等）有着广泛的应用。聚磷腈是骨架上磷原子与氮原子交替排布有机-无机杂化材料,两个侧链单元（通常是有机基团）通过共价键接到每个磷原子上。聚二氯磷腈（DPCP）是合成聚磷腈的重要中间体,DPCP上的氯原子通过亲核试剂取代得到生物稳定或生物可降解的聚合物[1,2]。由六氯三聚磷腈（HCCP）合成PDCP过程中,单体HCCP的纯化非常重要。通过重结晶与升华的方法来纯化HCCP,其纯度可由31P NmR来测定。纯净的HCCP在20 ppm处有

Advances in microbiology 2024年第6期14卷 333-339页

作者： Nor Hidayah Bohari Elya masya mohd Fishal Ili Bazilah Abd Razak muhammad Ashraf Arif mohd nasir Cik mohd Rizuan Zainal Abidin Crop Protection and Biosolutions Department FGV R&D Sdn Bhd Bandar Enstek Malaysia

The development of microbial-based products requires certain criteria for them to be successfully commercialized. The product must meet the following desirable criteria: effectiveness, contamination free, stability, cost-effectiveness, and a prolonged shelf life. Controlling the drying process is crucial for ensuring the stability and durability of the product. The traditional approach, which involved mechanical and natural drying, led to decreased productivity and quality. The objective of this research endeavour was to achieve a dry process enhancement while preserving the microbial quality of Trichoderma asperellum (m103). The temperature and relative humidity during the drying period were monitored under two conditions: with and without a dehumidifier. The results demonstrate that the dehumidifier increases drying period efficiency by up to 63%.

We present a general analysis on non-static axial system with dissipative shear-free anisotropic fluid using polynomial inflationary f(R) *** study the effects of dissipation on the dynamics of geodesic matter *** leads the system either to rotation-free or expansion-free but not both simultaneously under geodesic *** is found that the system preserves its symmetry in both *** the rotation-free case,when there is no dissipation and Ricci scalar is constant,the axial system reduces to FRW universe *** is exactly the same result obtained in general relativity.

The structural vibrational, thermodynamical, and optical properties of potentially technologically important, weakly coupled mAX compound, Sc2 Al C are calculated using density functional theory(DFT). The structural properties of ScAlC are compared with the results reported earlier. The vibrational, thermodynamical, and optical properties are theoretically estimated for the first time. The phonon dispersion curve is calculated and the dynamical stability of this compound is investigated. The optical and acoustic modes are observed clearly. We calculate the Helmholtz free energy(F), internal energy(E), entropy(S), and specific heat capacity(Cv) from the phonon density of states. Various optical parameters are also calculated. The reflectance spectrum shows that this compound has the potential to be used as an efficient solar reflector.
