Prerequisites

It is recommended that those students who have not studied Chemical subjects during the Bachelor attend the chemical courses, which the Faculty of Sciences organizes at the beginning of September.

Objectives and Contextualisation

The general objectives of the subject are to establish the fundamental concepts that allow understanding chemical reactions and to be able to relate them with other more specific subjects of the Degree of Nanoscience and Nanotechnology. These bases will allow the student to identify and apply the principles and their meaning to solve real world problems in a systematic and fast way and increase their critical and learning abilities.

The subject offers the students the fundamental principles of chemistry, their applications and qualitative and quantitative reasoning. Examples of the real world and more specifically of the field of Nanoscience will be given. The following areas will be emphasized: thermochemistry, homogeneous and heterogeneous equilibria, chemical kinetics, basic electrochemistry and organic chemistry.

  • Apply the concepts, principles, theories and fundamental facts of nanoscience and nanotechnology to solve problems of a quantitative or qualitative nature in the field of nanoscience and nanotechnology.
  • Apply the general standards for safety and operations in a laboratory and the specific regulations for the use of chemical and biological instruments, products and materials in consideration of their properties and the risks.
  • Be ethically committed.

Assessment

The final grade of the subject is obtained from the exam notes, the continuous work of the student (learning evidences) and of the practices.

Average of the exams of the subject = 0.50 x note exam block I + 0.50 x note exam block II

Final mark of the course = 0.85 x average mark of the exams of the subject + 0.15 x note continuous work + 0.20 x note practices

 

To pass the subject, the following three conditions must be fulfilled:

   1) The average of the exams of the subject should be ≥ 5.0

   2) The mark of the examination of each block must be ≥ 3.0

   3) The note of the practices should be ≥ 4.0

 

Students who do not pass the subject for failing to meet any of the above three conditions, regardless of whether the final grade is greater or equal to 5.0, they will obtain a maximum final grade of 4.5 considering- if the subject is suspended.

 

Continued work (10%):

1) Evidence of each student will be collected in each of the two blocks throughout the semester (problems solved individually or in groups, self-assessments on the virtual campus, short tests in class, tests, etc ...).

2) The note of the continuous work will be the average of the notes of the evidences collected throughout the course. The fact of not appearing to evidence implies a zero in that evidence.

 

Exams (70%):

1) An examination will be carried out at the end of each block (examination of block I and examination of block II).

2) At the end of the semester will be offered examinations of recovery of the two blocks (exams of second option).

- To participate in the recovery, the students must have been previously evaluated in a series of activities whose weight equals to a minimum of two thirds of the total grade ofthe subject.

- There is the possibility that students who do not need it will be presented to second-choice exams to improve the qualification of the course.

 

For all students to submit to these second-choice exams (recovery) or improvement), the block exam will be the one they get in this second option exam.

For all students to submit to these second-choice exams (improvement), the block exam will be:

   - equal to that of the second option exam, if the note of the second option exam> course examination note,

   - equal to the average of the block exam and the second option exam, if the note of the second option of the option < course exam notes.

 

Practices (20%):

The final mark of the practices will be calculated from the laboratory reports (60%) and the test exam of the knowledge acquired in the laboratory (40%).

 

Use unauthorized methods during one of the examinations of the subject (copy or communicate with a colleague, use of cell phones, use of smart clocks, etc ...) will be penalized with a "suspense" rating in the global course of the current course.

To attend an examination of any block it is essential to bring an identification document (ID or university card) with a recent and good quality photograph.

 

The qualification of "NOT EVALUABLE" will be obtained in the following cases:

  • There is no note of laboratory practices (attendance to the classes of practices is compulsory).
  • The student has not participated in any of the assessment activities of one of the blocks in which the subject is divided (exams and continuous work).
