In order to know the influence of Cs adsorption on the thermogravimetric properties from water that is not pure, the TG-DTAs of PB samples with 4 wt.% Cs adsorbed from pure water and 4 or 18 wt.% Cs adsorbed from the ash washed solution were compared. cesium adsorbed Prussian blue (PB-Cs) with 4 wt.% Cs adsorbed from the ash extract solution contained about 6 wt.% K, whereas that with 18 wt.% Cs contained about 2.5 wt.% K. This accounts for the total of about 10 wt.% and 20.5 wt.% alkali metals in those materials, respectively. As shown in Figure 2, for 10 C/min heating in dry air condition, the profile of PB loaded with 4 wt.% Cs, in general, looks similar to that without Cs, as shown in Figure 1. However, the thermogravimetric behavior largely changes when the Cs was adsorbed from ash extract solution. For the same 4 wt.% Cs from the ash extract solution the heights of the two peaks belonging to the exothermic reaction are switched. The major peak observed at around 300 C now becomes relatively very short and the second broad peak has become the major one, showing a significant temperature rise as well. The reason behind the different profiles for the materials with the same amount of Cs is the presence or absence of other alkali metal ions in the adsorption solution as PBA also adsorbs other alkali metal ions although the selectivity is highest for Cs [1,27]. The difference in the total mass loss between 4 wt.% Cs adsorbed from pure water (48%) and from the ash washed solution (40%) is due to the decrease in the effective mass of PB in the sample. With the increase in the amount of adsorbed Cs and other ions, the effective mass of PB taken for the TG-DTA drops, which also leads to a decrease in the energy released during hexacyanoferrate (HCF) oxidation. The second DTA peak with increased energy in this case is assumed to be of the oxidation of iron together with the formation of alkali metal compounds.

For PB with 18 wt.% Cs (plus 2.5 wt.% K) adsorbed from the ash extract solution (it was not possible to load more than 4 wt.% of Cs when in pure water solution), the DTA peaks were flattened. In this case, it should be noted that 20.5 wt.% mass is covered by Cs and K. Thus, PB out of 10 mg sample is at least 20.5 wt.% less (Rb not being analyzed). Therefore, if r-Cs are decontaminated from any solution system consisting of several other monovalent cations, PB adsorbs a much higher amount of Cs first and if there is more space other alkali metal ions like K and Rb also get adsorbed. This leads to a change in the thermogravimetric profiles to a great extent, most obvious being the suppression of the exothermic heat flow during the thermal oxidation. It can be understood as the decrease in the effective mass of the CN unit in the material after adsorption leads to a proportional decrease in the corresponding exothermic energy.
PB is a mixed oxidation state complex typically with 44% of FeII and 56% FeIII. Studies show that the light, temperature, and even change in the solvent system triggers the change in the ratio of FeII and FeIII [28,29]. This study being about the thermal treatment, gradual oxidation of FeII is assumed to take place likewise.
The first scale-up experiment was carried out taking 1, 5, and 9 g of PB-b with 2.5 wt.% adsorbed Cs. The amount of Cs in the adsorbent was estimated by the difference between the concentration of Cs in the feed solution and the residual concentration after adsorption. The heating was carried out using a rotating oven with a continuous flow of air, as shown in Scheme 1. For this, the material was packed in a hard glass container with an opening at both ends. It was then heated at 200 C for 40 min rotating at 30 rpm and passing the air at the rate of 400 mL/min. After cooling down to room temperature the thermal decomposition status was examined by TG-DTA. As shown in Figure 7a, 1 g fraction showed no visible change in the TG-DTA profile, suggesting the complete decomposition during the oven heating. The 5 g batch showed a changed DTA and a loss of 10 wt.%, but, no temperature surge was observed. On the contrary, the 9 g batch showed a PB-type TG-DTA profile with a significant temperature surge peak. This observation concludes that larger the mass, longer should be the heating time at the given temperature.

The detail of the pilot-scale test carried out in the Fukushima region on the selective removal of radioactive Cs (along with the naturally existing stable Cs) is discussed in reference [18]. After passing the given volume of the contaminated ash extract, the stainless columns were taken for thermal oxidation. Different from the lab condition, the daytime temperature of the test site on that particular day was about 10 C. Therefore, the preliminary heating at 220 C for achieving > 35% mass loss was carried out for 4 h. The observed data are summarized in Table 3. The point to focus on is the total mass loss.

Scotts recently introduced a new bluegrass / fescue blend that is supposed to survive even south of the transition zone. It's called Thermal Blue, but homeowners should be aware that it is definitely a cool-season grass.
Not only does Thermal Blue stand up to moderate summer temperatures extremely well, it shows outstanding shade hardiness. However, it is only intended to grow where you would normally expect to grow normal bluegrass. While claims to be able to grow south of the transition zone, it should be understood, that doesn't mean very far south of that zone.

The crosses in (b) are values calculated from the discharge curves of NMF83 and NCF90.
Blue Monster Arctic Armor creates a thermal barrier that protects surfaces from costly heat damage during soldering, welding and brazing operations. Spray on hard-to-reach surfaces or apply to any surface to shield studs, walls, doors and other surfaces from flames, sparks and molten splash.
Blue Flame E-Tech thermals not only insulate but use the super moisture-wicking properties of bamboo viscose to keep feet drier. While moisture build-up typically defeats most socks' insulative properties, these E-Tech are designed with thick inner loops of cushioning that trap heat and keep your feet warm and dry for hours. You can feel this sock working when you remove your foot from your footwear and you feel a wave of cool air created from rapid evaporation of moisture. This sock rates four flames out of four for thermal properties.
