Cargo Tracking Note certificate contains detailed information on cargo and its movement between ports. It’s also enables Marine Custom Authorities to access information about exporter/importer, shipping route and methods, type and value of the cargo, the value of the freight as well as the details about commodity being carried.

2023年7月13日 · A three-dimensional metal–covalent organic framework (3D-MCOF) based on cyclic trinuclear units was synthesized using organic tetrahedral linkers and copper-based cyclic trinuclear complexes. The novel type of 3D-MCOF, named 3D-CTU-MCOF, with the ctn topology, is reported herein for the first time.

电极的寿命在 3-12 周之间，膜成分和基于存储条件的性能特征没有显着变化。相对于常见的干扰分析物，该电极对 cTn 显示出高选择性。这种 Mn-MOF 电极方法可以解决、促进和帮助急诊科 (EDs) 对胸痛和早期心肌梗塞诊断患者做出决策。

The geometry of building blocks plays an essential role in the construction of target frameworks based on reticular chemistry, such as ctn, bor, pts, etc, whereas the geometric conformation of building blocks is the most effective method for selectively crystallizing specific topological structures, such as fjh and ljh. Consequently, based on ...

Four types of 1,3,5,7-tetrakis(4-aminophenyl)adamantine based covalent-organic frameworks (tapa-COFs) have been designed with diamond, ctn and bor net topologies using the methods of molecular mechanics and density function theory. Their low density (0.096–0.258 g cm−3), high porosity (90–96%) and large H2 accessible surface area (5511–6810 m2 g−1) forecast excellent hydrogen uptake ...

柑橘素 (ctn) 是一种霉菌毒素，主要由红曲霉属物种产生。 过量食用CTN可能会导致肾毒性和肝毒性。 本研究建立了一项商业化生产竞争性直接酶联免疫吸附测定 (cdELISA) 试剂盒和用于筛选红曲中 CTN 的免疫层析试纸条 (immunostrip) 的试点研究。

The Cargo Tracking Notes (CTN) is an official, maritime document issued upon shipment at the loading port and its mandatory for the importation and exportation in and out of Sierra Leone.

A regular slotted carton (RSC) box has four flaps on the top and bottom that meet at the center of the box when folded. The outer flaps of an RSC box partially overlap the inner flaps when closed. RSC boxes are commonly used for a wide range of products and are more cost-effective than full overlap carton boxes.

regular corrugated boxes (rsc) Custom sizes our specialty - low minimums - call for information. The highest quality manufacturing standards are used to make our boxes.

The ctn and bor networks are designed using the [T d + C 3] combination, which yields 3D COFs free of interpenetration with high surface areas. The dia network is formed using the [ T d + C 2 ] and [ T d + T d ] diagrams that produce the largest family of 3D COFs owing to the broad diversity of C 2 -symmetric linkers.
