Zirconia, ZrO2, was synthesized by calcination of pure, sulfate-impregnated, and phosphate-impregnated Zr(OH)4 at different temperatures in the range from 600 to 1100°C for 5 h. Weight variant and invariant processes involved were monitored by thermogravimetry, differential thermal analysis and differential scanning calorimetry. The bulk structure and phase composition of the zirconias thus produced were characterized by X-ray powder diffractometry, infrared absorption spectroscopy and Raman scattering spectroscopy. The results have been correlated, so as to reveal the influence of the sulfate and phosphate additives on the zirconia polymorphic transitions as a function of temperature. Accordingly, phosphate species have been revealed to stabilize or influence stabilization of cubic-structured zirconia at temperatures as low as 600-900°C, where it is otherwise unstable. IR- and LRa-observed formation of Zr2P2O7 species (cubic-structured) is suggested to act as seed species for the stabilized cubic structure of zirconia. An analogous stabilizing influence was revealed for sulfate species, however, toward cubic and/or tetragonal zirconia, and functions within the thermal stability range of the sulfate (i.e. up to 720°C).
Drug polymorphism refers to the ability of a pharmaceutical compound to exist in more than one crystalline form, each with distinct physical and chemical properties. This can impact the drug's solubility, stability, bioavailability, and ultimately its therapeutic effectiveness. Pharmaceutical companies must ensure consistent quality and performance of the drug product, despite potential polymorphism variation.
Polymorphism and Allotropy are same thing. Polymorphism is used for compounds and the allotropy is reserved for elements. You can go for XRD to check the crystal structure and their composition to distinguish.
Polymorphism in gel patterns can be seen as variations in the banding pattern of DNA fragments among different individuals. This can be observed by visualizing the different band sizes and intensities on a gel after the DNA has been separated based on size using techniques such as gel electrophoresis. The presence of different bands at the same locus indicates polymorphism.
Lysosomes play a role in polymorphism by helping to break down and recycle cellular materials that are no longer needed, thus contributing to genetic diversity within a population. Additionally, lysosomes are involved in processes that regulate cell signaling and immune responses, which can further influence polymorphism through interactions with environmental factors.
Polymorphism is found in the nucleus. More specifically, polymorphisms are variations in the DNA sequence within genes that can affect an individual's traits or characteristics. These variations can be passed on to offspring through heredity.

Polymorphism means multiple form of a function, variable or object. In Computer Science, polymorphism is a programming language feature that allows values of different data types to be handles using a common interface. There are three types : Ad-Hoc Polymosphism, Parametric Polymorphism, Subtype/Inclusion Polymorphism. Source: Wikipedia.
Yes, polymorphism exists between the prokaryotes.
Polymorphism is common with barbiturates, steroids, and sulphonamides.
Static polymorphism is used the concept of early binding or we can say compile time binding where as dynamic polymorphism used the concept of late binding or run time binding.
One can detect polymorphism by genetic marker using single-nucleotide polymorphism which is able to even tell mutation of a gene.
compiler can decide which form of the object should be invoked during compile time.this type of polymorphism is know as compile time polymorphism
No. Interfaces in Java are a construct to get polymorphism ( subtype polymorphism ) working in Java, but they are not a "kind" of polymorphism. In polymorphism happens when two objects respond to the same message ( method call ) in different way ( hence poly -> many, morphism -> way or shape : polymorphism -> many ways). In Java to be able to send the same message to two different objects you have to either inherit the same parent, or implement the same interface.
Runtime polymorphism is also called as method overriding, late binding or dynamic polymorphism. It is when a method in a subclass overrides a method in its super class with the same name and signature.
Polymorphism is the changing of one subject to an altered state. There are actually two areas of study where polymorphism would be particularly common: chemistry and web programming.
