Kernel Metadata Declaration — on demand

ISO 26324 asks a DOI Registration Agency to produce a Kernel Metadata Declaration for every DOI it issues. Give any DOI: its public record becomes a record in the Smart Scholars DOI Metadata Format 1.0, checked against every rule, and declared as the Kernel XML.

Reads the DOI's public Crossref record; nothing is stored. Until Smart Scholars is accredited, every Declaration is marked as a draft in the XML itself.

✓ Meets every rule of the format

The record below is complete and every controlled value is a DOI Attribute Value Set 2.3 spelling. The Declaration on the right follows DOIMetadataKernel.xsd element by element.

        "value": "Lopinavir is the anti HIV drug which is used to treat the HIV-1 infection. In this study we used the single lopinavir drug to formulate the polymeric micelle. This study was done with the two main objectives as Objective:first to enhance the solubility and bioavailability of the BCS class IV drug and second to avoid the combination of lopinavir rand ritonavir and use single lopinavir to preparation of polymeric micelle also to avoid the disadvantages related to the oral administration. Method:The different pluronic (F188 &F127) and co-solvent (Tween80) were chosen & the micelles were prepared by using different Drug: polymer ratio with or without cosolvent and drug Lopinavir. Formulations were been characterized by critical micelle concentration(CMC) value, micellesize,DSC, XRD, loading efficiency, % drug loading and stability.Result:Mixed micelle (hydrophobic &hydrophilic) obtained from optimized batch shows the highest entrapment of 29%with the pluronic F68 with the use of co-solvent and the vesicle size of 0.156µm the DSC, FTIR, XRD study was also done for lopinavir and optimized formulation .Conclusion: The pluronic F68 with the co-solvent showed fairly high entrapment efficiency, loading capacity than the mixed Pluronic in combination",

Everything Smart Scholars runsNine sites, one account. A journal starts at the audit; an author starts at Scholar Shield.

For journals & publishers

Start with the audit — it is free, and it is the gate to everything else.

DOI care

Nine services on one journal profile — each previews first and acts only on your approval.

For authors & researchers

Free to use. Nothing you check is shared with the journal.

For institutions, sponsors & DOI operators

Smart Scholars

Mon–Sat, 10:00–19:00 IST. The Ask AI button on every page answers about our services at any hour.
