Reichardt's dye. Reichardt's dye (Betaine 30) is an organic dye belonging to the class of azomerocyanine betaines. This dye is notable for its solvatochromic properties, meaning it changes color depending on the solvent in which it is dissolved. It has one of the largest solvatochromic effects ever observed, with color varying across the entire visible spectrum. As a result, it gives striking visual results for chemical demonstrations.

This chemical is named for , who developed it when working as a doctoral student in the lab of . It is thus also sometimes called Dimroth–Reichardt dye. The names also sometimes refer to some close chemical analogs, in particular, the one having para substituted tert-butyl groups on the phenyl rings.

Synthesis 

A newer synthesis is:

2,6-Diphenylphenol is nitrated with diluted nitric acid to 4-nitro-2,6-diphenylphenol and subsequently reduced with sodium dithionite to the amine. This is reacted in presence of sodium acetate in ethanol with 2,4,6-triphenylpyryliumhydrogensulfate to the hydrogen sulfate of the dye and the betaine is formed by adding sodium hydroxide.

UniEnergy Technologies. UniEnergy Technologies (UET) was a U.S. vanadium redox flow battery manufacturer in Mukilteo, Washington, which manufactured megawatt-scale energy storage systems for utility, commercial and industrial customers.  The company was founded in 2012 by Dr. Gary Yang and Dr. Liyu Li to commercialize a new Vanadium electrolyte formulation the pair had developed while working at Pacific Northwest National Laboratory.  The new formulation, a mixed-acid solution, was patented by PNNL and the patent was licensed to UET for commercialization.  The mixed-acid vanadium electrolyte allows for a wider temperature range for operations, and double the energy density of the traditional vanadium electrolyte.  
 
The company had designed a megawatt-scale flow battery using this new electrolyte for the purpose of allowing rapid deployment, manufacturing repeatability and lower costs.    The company also employed an R&D team which worked to make advances on the electrolyte chemistry and stack design.

UET had a subsidiary in Germany, Vanadis Power which provides sales and services for Europe. The company had partnerships with Bolong New Materials, a vanadium electrolyte manufacturer, and Rongke Power, the Chinese vanadium flow battery stack manufacturer. In December 2015 the company completed their B round funding series which included a major investment from Orix Corp. In October 2021, UniEnergy filed for involuntary Chapter 11 bankruptcy, listing no assets or debts.

Products
UniEnergy sold a 10kW, 34kWh fully integrated flow battery called the ReFlex.  This product was sized to be a building block for commercial and utility scale deployments from kilowatts to multi-megawatt installations.

Crucible tongs. Crucible tongs are scissors-like tools with a pair of attached arms that curve outward near the ends to form a rounded gripping area that allows users to safely grasp crucibles, flasks, evaporating dishes, or small beakers. They are made of durable metals—stainless steel, brass, or nickel, for example—that can withstand high temperatures.

Use
Crucible tongs are used most often with crucibles, small ceramic or metal vessels used to heat chemicals to temperatures up to 565.56 degree Celsius.

As a crucible will be very hot when heating it in a furnace or a Bunsen burner, one cannot hold the crucible directly. Therefore, crucible tongs come to play a key role when burning, or doing anything with hot objects. Moreover, some of them also have a special characteristic. For instance, a locking version of crucible tongs can be locked with the edge of a crucible, allow users to be more comfortable and more confidence while moving a very hot crucible from place to place. Hence, they provide more safety for the users.

Safety 
It is necessary to wear safety goggles, gloves, and proper shoes when using crucible tongs. The scorching objects in a crucible might be spilled off and cause damage to the holder's skin. Since crucible tongs work with the crucible, one must know the safety procedures of the crucible.
 Before using the crucible, make sure that it is dry
 Fill the crucible with sample chemicals to only 1/2 or 2/3, do not fill until it is full
 If the user used the crucible to fuse the glass, waiting for the crucible to cool down before cleaning it 
 Squeezing the crucible or use some metal sticks to break the cooling glass out of the crucible
 Wash it until it is clean enough

Tire manipulator. Tire Manipulator is a piece of equipment, or tool that is used for handling large OTR tires, or large wheels. Other names that are used for tire manipulator are tire handler or tire clamp. Tire manipulator is generally manufactured as an attachment which is a part of another vehicle. For example, a forklift, loader or another truck.

Use 
Tire manipulator is commonly developed and manufactured to customer specification because sizes of tires varies in every industry. In mining industry it is common to use tires with diameter over 3 meters. One of the biggest haulers in the world has tires with diameter of 4 meters. They can weigh over 2 000 kg. On the other hand, in agriculture tires are rarely greater than 2 meters, with weigh up to 1,000 kg.

Companies started to use tire manipulators mostly because of safety and effectiveness. In the past, many people were injured, or even killed by heavy tires exploding or falling. It was also time consuming to change tires. Mainly for these two reasons companies realised there is a need for special equipment that can handle large tires and service heavy wheels.

Nowadays, there are a number of tire manipulators in the market. Some of them are engineered to handle tires in agriculture, building industry, or material handling. You could find them under name Easy Gripper 2160, Tire Handler, Tire Manipulator, Giant Tire Handler, or Tire Clamp.

Palmqvist method. The Palmqvist method, or the Palmqvist toughness test, (after Sven Robert Palmqvist) is a common method to determine the fracture toughness for cemented carbides. In this case, the material's fracture toughness is given by the critical stress intensity factor KIc.

Approach
The Palmqvist-method uses the lengths of the cracks from a number of Vickers indentions to determine the fracture toughness. The Palmqvist fracture toughness is given by

 in units of MPa,

where HV is the Vickers hardness in N/mm2 (or MPa) (i.e., 9.81 x numerical HV), P is the indentation load in N (typically 30 kgf is used) and T is the total crack length (mm) after application of the indenter.

Renjin. Renjin is an implementation of the R programming language atop the Java Virtual Machine. It is free software released under  the GPL. Renjin is tightly integrated with Java to allow the embedding of the interpreter into any Java application with full two-way access between the Java and R code.

Renjin's development is primarily supported by BeDataDriven, but ultimately made possible by several current and past contributors including Mehmet Hakan Satman,
Hannes Mühleisen, and Ruslan Shevchenko.

History
Renjin's roots lie in an abortive 2010 attempt to compile the GNU R interpreter for the JVM via nestedvm, a toolchain which involves cross-compiling C and Fortran code to a static MIPS binary, which nestedvm
can then translate to JVM bytecode. This proved challenging as GNU R had grown to rely heavily on dynamic linking and the best C standard library
implementation available at the time for the MIPS architecture, Newlib, was not fully compatible with the GNU C Library, against which
GNU R had been developed.

The experience with the R4JVM project provided the BeDataDriven team with in depth look at the GNU R codebase, and convinced them
that a new implementation, written in Java, was a feasible undertaking. Development on Renjin began in October 2010, and rapidly resulted in 
a functional, if minimal, interpreter for the R language.

Continuous Function Chart. A Continuous Function Chart (CFC) is a graphic editor that can be used in conjunction with the STEP 7 software package or with other tools, such as CODESYS. It is used to create the entire software structure of the CPU from ready-made blocks. When working with the editor, you place blocks on function charts, assign parameters to them, and interconnect them.
Interconnecting means, for example, that values are transferred from one output to one or more inputs during communication between the blocks.

Continuous function charts are basically used for controlling continuous processes, where all the logic is executed and outputs are calculated in each PLC scan. 
Where as in SFC, execution will be sequential as done is batch processes.

Cubosome. Cubosomes are discrete, sub-micron, nanostructured particles of the bicontinuous cubic liquid crystalline phase. The term "bicontinuous" refers to two distinct hydrophilic regions separated by the bilayer. Bicontinuous cubic crystalline materials have been an active research topic because their structure lends itself well to controlled-release applications.

Cubosomes are liquid crystalline nano-structures formed from the cubic phase of lipids, such as monooleate, or any other amphiphilic macromolecules with the unique property to be dispersed into particles. Nano-vehicles are generated from a self-assembled lipid mixture and studied by means of high-resolution cryogenic transmission electron microscope (cryo-TEM). These structures have been observed to naturally occur in mitochondrial membranes and in stressed  cells.

Cubosomes are formed at controlled temperatures into lipid bi-layer twisted into three dimension with minimal surface forming a tightly packed structure with bicontinuous domains of water and lipid.
There are three different proposed phases that these cubic structures can be in: the P-surface, G-surface and D-surface for primitive, gyroid and diamond structures respectively. This variation in structure allows for cubosomes to be the ultimate drug delivery system due to its ability to maintain the structural integrity of the ingredients that it carries. The uses of cubosomes are still being researched but they range from systems for efficient drug delivery into specific body systems to stabilizing and producing palladium nanoparticles.

Uses 
For most fluids and some homogenous solid materials, like gels, diffusion is the same in all directions and characterized by the same diffusion coefficient number. This property is called isotropicity which gives cubosomes the ability to be used in biological tissues which are highly structured and typically have different diffusion coefficients along different directions (anisotropic). Because of advantages such as the unique structure of the cubic phase and its resemblance to biological membranes as well as biodegradability of lipids, cubosomes are a great tool for drug delivery system. In addition, the bicontinuous cubic liquid crystalline phase (cubic phase)’s tortuosity is useful for slowing down diffusion as shown by Higuchi’s square root of time release kinetics. Capability to encapsulate hydrophilic, hydrophobic, and amphiphilic substance, being simple to prepare, and all the aforementioned qualities give cubosomes a property that can be used in controlled transport applications as drug delivery vehicles.
