çalışmada dört yeni iminooksim ligandı, fenil-(1-fenil-etilimino)etanal oksim (ffeieoH), (2-hidroksi-etilimino)-2-fenil-etanal oksim (heifeoH), 2-(hidroksiimino)-1-feniletiliden]asetohidrazon (hifeahH2), (2-hidroksi-etilimino)-naftalin-2-il-etanal oksim (heineoH) ve bu dört ligandın palladyum(II) ve platin(II) iyonlar…
Ligth-induced changes in the optical properties of Ge-Te-In thin films have been studied. The refractive index, the absorption coefficient and the optical band gap of the films have been determined before and after exposure by analyzing the material's transmission spectrum. The thin film's nonuniform thickness was acc…
La adsorcion con intercambiadores de tipo compuesto esta incrementando su aplicacion en el tratamiento de residuos liquidos radioactivos por su mayor estabilidad frente a la radiacion y su mayor selectividad frente a determinados radionucleidos. El objetivo de este trabajo es la sintesis de un material adsorbente basa…
수중 음이온계 고분자 물질과 콜로이드의 상호작용은 입자 안정화, 혹은 반대로 응집에 영향을 미친다. 예를 들어, 휴믹물질의 경우 입자 안정화하고 PAM의 경우 입자 응집을 도모한다. Stericrepulsion 작용하에는 입자표면의 고분자물질이 입자 반발력을 증대시켜 안정화 한다. Chargeneutralization 에서는 고분자물질이 입자표면의 정전기력을 중화시키므로 응집을 증대시킨다. Bridging mechanism 작용하에는 고분자물질이 입자를 서로 엉겨붙게 만들어 응집을 증대시킨다. 이와 같은 고분자 물질의 입자 응집 및 안정화 작용에는 다양한 물리화학적…
The analysis of the main technical characteristics of ships and floating crafts to transport bulky especially heavy loads has been presented; some recommendations for transporting oil and gas equipment by sea have been given.
Purpose/hypothesis: Regular practice of exercise is the most effective non-pharmacological intervention that improves vascular health, which is thought to be mediated by a repeated exposure of vessel walls to increased hemodynamic shear stress (SS). Mitochondria have been shown to be essential cellular structures resp…
Material blok mesin aluminium dalam pengunaannya sering terjadi masalah abrasi pada jalur sirkulasi pendingin dan terjadi kerusakan retak dan patah. Perbaikan blok mesin biasanya menggunakan las oxy-acetylene. Refrensi ilmiah pengelasan blok mesin dengan las oxy-acetylene sangat minim, sehingga pelaksanaan pengelasan…

a b s t r a c t Polymer colloids are usually prepared using thermally activated polymerization. Photo-induced tech- niques for the preparation of polymerized or crosslinked colloids have seldom been reported in the literature and to our knowledge none has found real application in industry. Here, we introduce a new ap…

In this study, epoxy filled 1, 3, and 5 years old Giganthochloascorthechinii and 10wt% of salacca sp. composite was conducted. Compression molding method is used to produce this biodegradable and green composite. Archimedes principles was used to test the density of composite, modulus of elasticity (MOE) and modulus o…
In cross-flow microfiltration (CFMF), suspended particles deposit to form a cake layer on the membrane surface, which provides a resistance to permeate flow. The cake resistance, which plays an important role on the performance of CFMF, is mainly determined by the packing porosity of the cake and, the physical and che…
The effect of continuous CO 2 laser radiation on the optical properties of pure polyvinyl chloride and doped of ZnO nanoparticles with two different concentrations (10, 15%) has been investigated. All samples were prepared using casting method at room temperature. Optical properties (absorption, transmission, absorpti…

Abstract: this article present experimental data of the comparative analysis of the various conditions of poly…
Perylene monoimides or monoanhydrides are being intensively investigated as sensitizers in DSSCs. Keeping only one acceptor group, i.e. imide or anhydride, and introducing a donor group in the 9-position (such as diarylamine) proved to be important in order to obtain a favorable orbital partitioning strength and dipol…

本文合成了2个新的含乙酰氧肟酸配体的席夫碱钒配合物，[VⅢL1（HAHA）]（1）和[VⅤOL2（AHA）]（2），其中L1为N，N’-二（5-甲基水杨基）乙烷-1，2-二胺的二价阴离子，L2为2-{[2-（2-羟乙基氨基）乙亚胺基]甲基}-6-甲基苯酚的一价阴离子，HAHA和AHA分别为乙酰氧肟酸的一价和二价阴离子，通过物理-化学方法以及单晶X-射线衍射表征了它们的结构。在每个化合物中，V原子都采取八面体配位构型。本文还研究了配合物的热稳定性以及其对幽门螺旋杆菌脲酶的抑制活性。在浓度为100 μmol·L-1时，配合物1和2对脲酶的抑制率分别为37.2%和81.5%，其中配合物2的IC50值为21.5 μmol·L-1。分子对接…
It is shown that estimation of hardening of metals and alloys on hardness criterion makes it possible to compare materials with different levels of plasticity, even absolutely fragile with the plasticity close to zero. For the evaluation of hardening of metals and alloys with regard to their density introduced a featu…
An entry from the Cambridge Structural Database, the world’s repository for small molecule crystal structures. The entry contains experimental data from a crystal diffraction study. The deposited dataset for this entry is freely available from the CCDC and typically includes 3D coordinates, cell parameters, space grou…
