NLT 80% of batch volume ethanol was transferred into a manufacturing vessel.
Propylene glycol was added to a vessel containing ethanol. Melphalan was added to the above mixture. Check the pH of the sample and if required adjust the pH to 3.5-5.5 using 0.1N NaOH/0.1N HCL. Final batch volume was made up using ethanol. The obtained solution was filtered and filled in vials followed by capping and sealing. The formulation was tested for stability at 2-8° C. for a period of 1 Month. Stability data is summarized 13A.

In some applications, an infrasonic sensor is desired, with a frequency response fl that extends to an arbitrarily low frequency, such as a tenth of hundredth of a Hertz. Such a sensor might be useful for detecting fluid flows associated with movement of objects, acoustic impulses, and the like. Such an application works according to the same principles as the sonic sensor applications, though the length of individual runs of fibers might have to be greater.
In addition, the voltage response of the electrode output to movements is proportional to the velocity of the fiber, and therefore one would typically expect that the velocity of movement of fluid particles at infrasonic frequencies would low, leading to low output voltages. However, in some applications, the fluid movement is macroscopic, and therefore velocities may be appreciable. For example, in wake detection applications, the amplitude may be quite robust.
Generally, low frequency sound is detected by sensors which are sensitive to pressure such as infrasound microphones and microbarometers. As pressure is a scaler, multiple sensors should be used to identify the source location. Meanwhile, due to the long wave length of low frequency sound, multiple sensors have to be aligned far away to distinguish the pressure difference so as to identify the source location. As velocity is a vector, sensing sound flow can be beneficial to source localization. There is no available flow sensor that can detect infrasound flow in a broad frequency range with a flat frequency response currently. However, as discussed above, thin fibers can follow the medium (air, water) movement with high velocity transfer ratio (approximate to 1 when the fiber diameter is in the range of nanoscale), from zero Hertz to tens of thousands Hertz. If a fiber is thin enough, it can follow the medium (air, water) movement nearly exactly. This provides an approach to detect low frequency sound flow directly and effectively, with flat frequency response in a broad frequency range. This provides an approach to detect low frequency sound flow directly. The fiber motion due to the medium flow can be transduced by various principles such as electrodynamic sensing of the movement of a conductive fiber within a magnetic field, capacitive sensing, optical sensing and so on. Application example based on electromagnetic transduction is given. It can detect sound flow with flat frequency response in a broad frequency range.
For the infrasound detection, this can be used to detect manmade and natural events such as nuclear explosion, volcanic explosion, severe storm, chemical explosion. For the source localization and identification, the fiber flow sensor can be applied to form a ranging system and noise control to find and identify the low frequency source. For the low frequency flow sensing, this can also be used to detect air flow distribution in buildings and transportations such as airplanes, land vehicles, and seafaring vessels.
The infrasound pressure sensors are sensitive to various environmental parameters such as pressure, temperature, moisture. Limited by the diaphragm of the pressure sensor, there is resonance. The fiber flow sensor avoids the key mentioned disadvantages above. The advantages include, for example: Sensing sound flow has inherent benefit to applications which require direction information, such as source localization. The fiber flow sensor is much cheaper to manufacture than the sound pressure sensor. Mechanically, the fiber can follow the medium movement exactly in a broad frequency range, from infrasound to ultrasound. If the fiber movement is transduced to the electric signal proportionally, for example using electromagnetic transduction, the flow sensor will have a flat frequency response in a broad frequency range. As the flow sensor is not sensitive to the pressure, it has a large dynamic range. As the fiber motion is not sensitive to temperature, the sensor is robust to temperature variation. The fiber flow sensor is not sensitive to moisture. The size of the flow sensor is small (though parallel arrays of fibers may consume volume). The fiber flow sensor can respond to the infrasound instantly.
Note that a flow sensor is, or would be, sensitive to wind. The sensor may also respond to inertial perturbances. For example, the pressure in the space will be responsive to acceleration of the frame. This will cause bulk fluid flows of a compressible fluid (e.g., a gas), resulting in signal output due to motion of the sensor, even without external waves. This can be advantages and disadvantages depends on the detailed applications. For example, it can be used to detect flow distribution in the buildings. If used to detect infrasound, the wind influence be overcome by using an effective wind noise reduction approach.

113 g of sodium metal was melted and brought to 250° C. in an Inconel reactor vessel. The sodium was then stirred using a Cowles blade mixer rotating at 2000-2500 rpm. Powdered hafnium chloride (from Areva) was pulse-fed over approximately 1 hour into the stirred sodium, until 82 g of hafnium chloride had been added, at which point the reaction was halted. At the end of the reaction, the vortex in the sodium had substantially disappeared and the reactor temperature had increased to 301° C.
Once the reaction was completed, the reactor vessel was sealed, transferred to a furnace, and heated to 825° C. for four hours to reduce the surface area of the hafnium metal produced in the reaction. During this process step, unreacted sodium was removed from the hafnium metal to leave a hafnium-sodium chloride composite.
The hafnium and sodium chloride mixture was then transferred to a vacuum furnace and heated under vacuum to 2300° C., held at that temperature for one hour, and then cooled. This removed the sodium chloride and produced a button of solid hafnium.
The hafnium button was analyzed via glow discharge mass spectrometry (GDMS) and found to have 26 ppm oxygen content, 1690 ppm zirconium, and less than 150 ppm total transition metals. The results demonstrate the production of a low oxygen hafnium metal produced directly from hafnium powder consolidation.

Cyclohexene (1a) and polar organic solvent (as mentioned in Table 1) in (1:2 to 1:10 weight ratio with respect to the substrate) was taken in to a 60 ml vessel. Further, the hybrid photocatalyst was added and the resulting mixture was saturated with CO2 by purging at 1 atm pressure. The reaction vessel was sealed and irradiated with 20 W LED light (Model No. HP-FL-20 W-F, Hope LED Opto-Electric CO., Ltd) for 24 h. The conversion of the olefin and selectivity of the α,β-unsaturated hydroxyl or carbonyl compound as determined by GC-FID and GC-MS is mentioned in the Table 1 (entry 8-13).

Cyclohexene (1a) and polar organic solvent, preferably acetonitrile in (1:2 to 1:10 weight ratio with respect to the substrate) was taken in to a 60 ml vessel. Further, the bare graphene oxide as photocatalyst (1 to 10 mol % of the substrate) was added and the resulting mixture was saturated with CO2 by purging at 1 atm pressure. The reaction vessel was sealed and irradiated with 20 W LED light (Model No. HP-FL-20 W-F, Hope LED Opto-Electric CO., Ltd) for 24 h. The intensity of the LED light at the reaction flask was measured to be 86 W/m2 by intensity meter. The conversion of the olefin was examined by GC-FID based on the unreacted substrate. The selectivity of the α,β-unsaturated hydroxyl or carbonyl compounds was determined by GC-MS. The conversion of olefin and the selectivity towards the corresponding α,β-unsaturated hydroxyl and ketone is given in the Table 1, entry 3.
