SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.
SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal’s impact.
The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years.

To calculate the five year Impact Factor, citations are counted in 2014 to the previous five years and divided by the source items published in the previous five years.

Scripta Materialia is a LETTERS journal of Acta Materialia, providing a forum for the rapid publication of short communications on the relationship between the structure and the properties of inorganic materials. The emphasis is on originality rather than incremental research. Short reports on the development of materials with novel or substantially improved properties are also welcomed. Emphasis is on either the functional or mechanical behavior of metals, ceramics and semiconductors at all length scales.
The following aspects are of particular interest:
(i) discovery or development of new materials with novel functional or mechanical properties of potential engineering interests;
(ii) characterization of the structure and chemistry of materials for understanding the properties;
(iii) cutting-edge experiments and theory for understanding structure-property relationships;
(iv) novelty in simulation and modeling in the context of understanding properties, preferably combined with experimental verification;
(v) elucidation of the mechanisms involved in the synthesis and processing of materials as a route to the elucidation of properties;
In addition, Scripta Materialia publishes comments on papers published in Acta Materialia and Scripta Materialia. The journal also publishes Viewpoint Sets, which are a collection of invited short articles focused on topics of current interest within the scope of the journal and coordinated by invited guest editors.
