Ultrasonic Dispersion in the Particle Size Analysis of Titanium Dioxide
As a high grade white pigment, titanium dioxide is utilized extensively across a variety of chemical applications. Due to its exceptional gloss, stability whiteness and hiding power, titanium dioxide is suitable for coatings, plastics, papers, printing inks, chemical fibers, rubbers, cosmetics, etc.
The high surface energy of oxygen atoms means that there is a powerful interaction in the surface of inorganic oxide particles resulting in the titanium dioxide forming agglomerated particles.
Generally, analysis accuracy of single-particle size will be affected in laser diffraction and SEM (Scanning Electron Microscope) measurements because of the agglomeration of the titanium dioxide particles.

The Global Rheometer & Viscometer Market is estimated to be USD 802 Mn in 2020 and is expected to reach USD 966.5 Mn by 2025, growing at a CAGR of 3.8%.
Major factors that drive the market growth are rapid technological advancements and increasing R&D investments by manufacturers in rheometer & viscometer for various end-use industries. Expansion of petrochemical and material manufacturing industries and growing stringency of the government regulatory framework for product safety compliance in pharmaceutical industries, cosmeceutical, and biotechnological companies also help in promoting the growth. Besides, the rising public-private investments to support product innovation and increasing the number of target diseases helps in boosting the market growth to a certain extent. Furthermore, high usage of viscometers in chemical, petroleum, oil, and gas industries and the availability of innovative and affordab
Many a cannabis consumer has an intimate relationship with his bud. But few have gotten as up close and personal with pot as Ted Kinsman, a scientific photographer at Rochester Institute of Technology who does not indulge in the jolly green grass. When Kinsman’s otherworldly images of microscopic parts of the cannabis plant started circulating on the internet in 2018, not everyone believed what they were seeing. Some took to Snopes.com to verify that the suspiciously psychedelically-hued images were true representations of pot. The sleuthing site confirmed that they were genuine images of cannabis, but clarified that Kinsman had digitally colorized them to make parts of the plant pop specifically the parts that get you high.

In comparison to the conventional light microscopy, cryo electron tomography is a powerful tool that offers much deeper insights into the cell structure by unveiling high-resolution 3D views of biological samples such as large macromolecules. In the first step, samples are immobilized by high-speed freezing at extreme temperatures under ?150 °C. These cryogenic conditions make it possible to study samples without chemical fixation or dehydration, thereby preventing distortion or disruption of biological structures of the sample. However, the preparation and the handling of the samples are very complex, since the formation of crystalline ice can compromise the structural integrity of the specimen. Sebastian Tack
