As science and industrial production continue to advance, the measurement of viscosity in substances has become a crucial aspect of various processes. One of the most widely used tools for this purpose is the rotary digital viscometer, which allows for the accurate measurement of viscosity and flow behavior of polymer liquids.

The concept of rotary viscometry was pioneered by the Brookfield family in the United States, who introduced a rotational viscosity measurement method. This method relies on the unique relationship between shear and resistance generated between the rotating rotor and the fluid to obtain dynamic viscosity values. Over the years, this technology has evolved and improved, and today’s rotary viscometers, like the brookfield viscometer series, offer exceptional performance and versatility.

Rotary digital viscometers come in different types, each tailored for specific applications:

Drum Viscometer: This type features a flat-bottomed cylinder with a coaxial cylinder in the center. The polymer liquid is placed in the slit formed between the two parallel surfaces. The cylinder is rotated by a stepless governor, and the viscosity of the liquid causes the cylinder to rotate until the torque balances with the spring force. The resulting angle of rotation provides information about shear force and shear rate at various positions in the annular seam.

Vertebral-plate Viscometer: Consisting of an upper cone and a lower disc, this viscometer has the cone and the circular plate on the same axis and both are rotatable. The polymer melt is placed in the slit formed by the cone and the circular plate at a specific angle. When the circular plate rotates, it drives the cone to rotate until a certain angle is reached, providing viscosity data.

Falling Ball Viscometer: Though less commonly used for measuring melt viscosity, this type is suitable for Newtonian fluids. It involves a ball falling through the liquid, and the maximum shear rate near the ball can be estimated. However, data processing can be challenging, and it is not ideal for comprehensive analysis of non-Newtonian fluids.

When selecting a rotary viscometer, the NDJ-8S type low viscosity viscometer is a popular choice with the following main parameters:

Measuring Range: 10 ~ 1×10^5 mPa.s

Rotor Specifications: 0, 1, 2, 3, 4, and No. 5 rotors (No. 0 rotor optional, for low viscosity down to 0.1 mPa.s)

Instrument Speed: 6 rpm, 12 rpm, 30 rpm, 60 rpm

Measurement Error: ±5% (Newtonian liquid)

Power Supply: 220V ± 10V; 50Hz

Net Weight: 1.5 Kg

When choosing the appropriate rotor and speed, one should estimate the viscosity range of the liquid to be tested and then refer to the range table. For instance, if the viscosity is around 3000mPa·s, a No. 2 rotor at 6 rpm or a No. 3 rotor at 30 rpm could be suitable.

If the viscosity cannot be estimated, a higher density should be assumed, and a range of rotors and speeds should be used, starting from small rotors and slow speeds for high-viscosity liquids and vice versa for low-viscosity ones.

To calculate the actual viscosity from the indicated viscosity on the dial, a specific coefficient from the coefficient table must be used. Additionally, if the frequency of the power supply is inaccurate, the NDJ-8S rotational viscometer can be corrected using a simple formula.

In conclusion, rotary digital viscometers offer invaluable insights into the viscosity and flow behavior of polymer liquids, playing a vital role in modern industrial processes. Proper selection and utilization of these instruments can significantly enhance the efficiency and quality of various applications in the field of polymer production and beyond.

What is ZnSe?

ZnSe stands as a prototypical II-VI semiconductor material, possessing a zinc blend structure and a direct band gap. At room temperature (300K), its band gap is 2.698eV, and at low temperatures (<10K), it increases to 2.821eV, corresponding to blue light with a wavelength of 459.4nm.

Applications and Research of ZnSe

Researchers have employed thermal evaporation of ZnSe powder in a high vacuum for various applications. Deposition of ZnSe monolayers with thicknesses ranging from 30 nm to 1 µm on c-Si and glass substrates has been achieved at room temperature.

Furthermore, researchers have investigated SiOx/ZnSe periodic multilayer films using the same deposition technique, with ZnSe layer thicknesses of 2 and 4 nm. The Raman spectra, measured at 295K with various laser lines, revealed distinct Raman signatures corresponding to multiple optical phonon (1LO to 4LO) light scattering and randomly oriented crystalline ZnSe grains in both monolayers and multilayers.

Notably, relatively large line widths of the 1LO band (approximately 15 cm-1) were observed, which were associated with lattice distortions in the grains and the presence of amorphous phases in layers thinner than 100 nm.

The Behavior of ZnSe in Raman Analysis

During the experiments, all measurements were conducted in air at room temperature, and the spectra were plotted on the same graph with consistent scaling.

In the upper panels, Raman spectra of 1 µm (a) and 30 nm (b) ZnSe monolayers and SiOx (4 nm)/ZnSe (4 nm) multilayers (c) were measured under three different laser excitations.

Figure 1a showcases three Raman spectra of a 1 µm-thick ZnSe layer deposited on a Corning 7059 glass substrate. Superior resolution was obtained with excitation conditions near the resonance Raman scattering conditions.

The most substantial enhancement of the Raman signal was observed when the excitation light closely matched the material’s optical bandgap, Eg0. This aligns with prior findings indicating that for a 1 µm-thick ZnSe layer, the optical absorption follows the laws of directly allowed electronic transitions in crystalline semiconductors.

Figures b and c exhibit the Raman spectra of a 30 nm-thick ZnSe layer and a SiOx (4 nm)/ZnSe (4 nm) multilayer, respectively, both deposited on a c-Si substrate. In these spectra, a narrow solid band peaked at 521 cm-1 appeared due to scattering from the substrate. The 1LOZnSe band intensity increased with decreasing excitation wavelength, and a series of 4 peaks were visible only in the spectrum excited by the 457.9 nm line.

In practical applications, SiOx/ZnSeML (with various thicknesses between 2 and 10 nm) were characterized using Raman spectroscopy with the 442 nm line, revealing resonance behavior in the Raman spectrum associated with size-induced variation of the bandgap energy with layer thickness.

The Raman spectra of ZnSe monolayers with four different thicknesses are depicted, showing that the 30 nm layer’s 1LO band exhibited significantly higher intensity than the other samples. The results indicate that ZnSe layers with thicknesses less than 50 nm can exhibit excellent chemical sensitivity due to their small grain size.

The heat treatment process involves three main steps: heating, heat preservation, and cooling. It is used to enhance the properties of materials such as steel, aluminum alloy, copper alloy, and titanium alloy. Different heat treatment processes include quenching, tempering, normalizing, and annealing.

Quenching:

Quenching steel involves heating it to a temperature above the critical temperature Ac3 (for hypo-eutectoid steel) or Ac1 (for hyper-eutectoid steel). The steel is then kept at this temperature for a specific period to fully or partially austenitize it. Afterward, the steel undergoes a rapid cooling process, below the Ms temperature (or isothermally near Ms), at a cooling rate higher than the critical cooling rate. This results in the formation of martensite or bainite, leading to significant changes in the steel’s properties.

The purpose of quenching includes improving the mechanical properties of metal products or parts, enhancing the material properties of certain steels (e.g., corrosion resistance in stainless steel), and achieving high hardness and wear resistance in tools and bearings.

Tempering:

Tempering is a heat treatment process that follows quenching. In this process, the quenched metal product or part is heated to a specific temperature and held for a certain duration. It is then cooled in a controlled manner. The main purposes of tempering are to reduce internal stress and brittleness, adjust the mechanical properties of the workpiece (e.g., hardness, strength, plasticity, and toughness), and stabilize the metallographic structure.

The function of tempering is to improve the stability of the structure, eliminate internal stress, and adjust the mechanical properties of steel to meet specific application requirements. As the temperature rises during tempering, atomic activity increases, allowing for rearrangement and combination of atoms, resulting in the transformation of unstable structures into stable ones.

There are different tempering requirements for workpieces depending on their intended use. Low-temperature tempering (below 250°C) is used for tools, bearings, and carburizing and quenching parts. Medium-temperature tempering (350-500°C) is suitable for springs and forging dies, while high-temperature tempering (500-650°C) is used for gears and crankshafts.

Normalizing:

Normalizing is a heat treatment process that enhances the toughness of steel. It involves heating the steel components to a temperature slightly above the Ac3 temperature and then air-cooling. The cooling rate during normalizing is faster than annealing but slower than quenching. The process refines the crystal grains of the steel, resulting in improved strength and reduced cracking tendency.

Annealing:

Annealing is a metal heat treatment process in which the metal is slowly heated to a certain temperature, kept for a sufficient time, and then cooled at an appropriate rate. The purpose of annealing is to improve or eliminate various structural defects and residual stresses in the material, soften the workpiece for cutting, refine the grain and improve its structure to enhance mechanical properties, and prepare the tissue for final heat treatment (e.g., quenching and tempering).

There are various annealing processes, including fully annealing, spheroidizing annealing, isothermal annealing, recrystallization annealing, graphitization annealing, diffusion annealing, and stress relief annealing. Each process serves specific purposes and is applied based on the characteristics and requirements of the material or workpiece being treated.

These substances can serve as habitats for microorganisms and may interfere with the effectiveness of decontamination agents like antibacterials, chemical germicides, and disinfectants. To achieve effective disinfection and sterilization, cleaning is a necessary first step.

Cleaning Methods:

Surface Cleaning: Begin by brushing off any dust present on the CO2 incubator’s surface. Next, use a wet sponge or soft cloth soaked in soapy water or a low-concentration detergent to clean the surface thoroughly. After cleaning, dry the surface with a soft cloth.

Interior Cleaning: For the interior of the CO2 incubator, select a suitable disinfectant. Clean all objects and surfaces within the incubator, then rinse them with sterile water. Afterward, either wipe the surfaces dry or allow them to air-dry.

It’s essential to use cleaning reagents that are chemically compatible with the subsequent disinfectant or sanitizer to be used. This ensures optimal results during the cleaning process.

Tip 2: Sterilizing the CO2 Incubator

The CO2 incubator is designed to simulate the growth environment of cells, tissues, and microorganisms accurately. Alongside precise environmental control, proper disinfection and sterilization are critical to maintain an effective cultivation process.

Distinguishing Disinfection from Sterilization:

Disinfection: This method involves using physical or chemical means to kill microorganisms, but it may not necessarily eliminate their spores. Disinfection measures are typically employed when the cells within the CO2 incubator are contaminated.

Sterilization: Sterilization is a more rigorous approach, aiming to eradicate all organisms, including their spores. It is generally carried out every 1-3 months, even when the cells in the incubator are not contaminated.

Methods of Disinfection and Sterilization:

Liquid Disinfectant: Choose a non-corrosive liquid disinfectant that suits the CO2 incubator. The effectiveness of the disinfectant depends on various factors, such as temperature, pH, contact time, penetration ability, and organic matter. Ensure meticulous attention to these factors for successful disinfection.

Ultraviolet Disinfection: Following a thorough cleaning with distilled water, expose the interior of the CO2 incubator to the ultraviolet (UV) lamp that comes with the equipment. UV lamps can help eliminate residual microorganisms and create a sterile environment.

Dry Heat Sterilization: Dry heat sterilization can be employed as an additional measure for contamination-hazardous areas. It involves exposing the CO2 incubator to direct heating up to 120°C for over 2 hours. This high temperature effectively destroys bacteria, ensuring a clean environment for cell culture.

In conclusion, the proper maintenance of CO2 incubators through regular cleaning and effective sterilization methods is crucial to create a safe and superior culture environment. By choosing suitable disinfection functions and implementing timely and appropriate cleaning techniques, researchers can ensure consistent contamination control and optimal results for their cell cultures.
