In addition to the thermal effects, microwave may have some subtle effects (on-thermal effects) on the structure and the conformation of the enzyme molecules, which may reflect in the catalysis activity.
This study was to obtain the effect of microwave on papain activity and its conformation, and expected to provide the basis for the application of microwave in the enzyme chemistry and enzyme concentration.
The large numbers of the intermolecular disulfide bonds increased the stability of papain, and they effectively protected the structure of the enzyme molecules in the microwave processing.

As a batch process, the wasteform chemistry can be readily adjusted on a given process line, to deliver wastes into different end states (e.g. direct HIP versus chemically tailored).
Here the U is reduced to the tetravalent state and mainly inhabits a pyrochlore structured phase having an approximate CaUTi2O7 stoichiometry, while some brannerite, UTi2O6, may also be present in small quantities.
Recent unpublished work at ANSTO has shown that HIPing at 1400oC /100MPa of simulated spent fuel made from sol-gel precursors which were calcined in H2/N2 atmospheres at 700oC has potential in exploring the crystal chemistry of semi-volatile fission products in spent nuclear UO2 fuel.
As a batch process, the waste form chemistry can be readily adjusted on a process line if the waste composition and therefore the required additives change significantly.

Because of its semi-crystalline ring structure, amylopectin is able to form a soft gel phase that causes easily flow during the process.
The structure of macroinitiator Ap-TBBiB was determined by FTIR and 13C-NMR as shown in Figure 2(a) and 2(b).

The electronic structure makes the main effect on the property of the materials, but the structure of TiB2/Cu composite and doped series is no studied so far and not clear.
DFT-DVM method can be used to calculate larger structure models of molecules, clusters and solids, so it has been widely used in chemistry, physics, material science and so on[6-7].
TiB2 has the space group of P6/mmm and the layer-crystal structure with B6 and Ti7 (one Ti atom is in the center) hexagons.
Comparing with the structure of TiB2, there is similar symmetry of the structure of Cu in the direction of the diagonal of the cube model, with Cu7 hexagons (it is same as Ti7 in TiB2) and Cu3 triangle (or Cu6 triangle, as shown in Fig.1) layers.

However, exact nature of this feature is unknown and further research is required to determine its (a) nature, type, chemistry, morphology and crystal structure.
Their exact nature and chemistry are unknown.
This is due to alloy chemistry, area / point of examination and very slow heat transfer conditions prevalent there.
This is thought to bear cubic structure with (Fd – 3m) symmetry [44].
