Anodization of aluminum in a sealed container
Sealed anodization was studied for the first time in this paper. With the other conditions remaining the same, anodization under normal pressure was also carried out for comparative purposes.

The proposed method for measuring the liquid level focuses on the ultrasonic impedance and echo energy inside a metal wall, to which the sensor is attached directly, not on ultrasonic waves that penetrate the gas–liquid medium of a container. Firstly, by

Physical means of securing information, such as sealed envelopes and scratch cards, can be used to achieve cryptographic objectives. Reasoning about this has so far been informal.\ud \ud We give a model of distinguishable sealed envelopes in Z, exploring design decisions and further analysis and development of such models.

Optimized Preparation of Polyacrylonitrile/Sulfur Composite as Cathode for Lithium Sulfur Batteries
The polyacrylonitrile/sulfur (PAN/S)composite was prepared by heating the mixture of polyacrylonitrile (PAN) and sulfur under sealed conditions. The effects of the ratio of raw materials, reaction temperature, reaction time and reaction container volume ...
