Graphene is one of the varieties of carbon. It is one of the first discovered and stable two-dimensional materials. Graphene consists of a single, transparent layer, tightly packed atoms. Its structure resembles a honeycomb.

Other varieties of carbon are diamond or graphite. The lattice consists of many layers of graphene stacked on top of each other. Already in the nineteenth century, scientists speculated that graphite consis...

Introduction 

Luminescence on it’s own is the spontaneous emission of light in the form of cold body radiation from a substance. Such emission of light can occur due to stress of a crystal, electrical energy, subatomic motions as well as chemical reactions (5). Due to the light being emitted by all these factors except heat, is exactly what separates luminescence from Incandescence, being light emitted as a result of heat. Othe...

Introduction

Chromatography, is a well known method used to separate compounds using two phases; a mobile as well as a stationary phase. In Thin Layer Chromatography, the stationary phase is a thin layer such as silica on a plate and the mobile depends on the sample that is investigated. The sample is spotted on the origin line of the TLC plate and put upright in a TLC chamber with eluent in the bottom, in which the capillary a...

Curious or you have trouble understanding the Acids and Bases in Chemistry? Here is a summary to help you get started! :)

The characteristics of equilibrium are:

It is dynamic, e.g can go in both directions.

It is only achieved in closed systems.

The concentration is constant.

There is no macroscopic directions.

At equilibrium the rate of the forward and the backward reaction is equal to the rate of the backward reaction. Reactants ⇆ Products.

There are two types of equilibrium; physical systems and chemical systems.

In a physical equilibrium it is the...

Atomic radii - The measure of the disrance from the center of the nucleus to the boundary of the surrounding cloud of electrons orbiting it. Considering electrons do not have definite orbits, the atom is treates as a solid sphere instead, giving us an estimation instead. 

Ionic radii (in a crystal lattice) - The measure of half the distance between two ions that are barely in contact. Considering electrons do not have definite...

In a previous blog post named Chemical reaction we discussed what a chemical reaction is. We also talked about endothermic and exothermic reactions. Today we will build upon that knowledge.

Enthalpy is all energy in a system, including the energy stored in bonds, the energy that is heat etc. You can’t measure all the enthalpy in a system, only how it changes when a chemical reaction occurs. ΔH is the symbol for the enthalpy cha...

Topography of tears😢, using a microscope 🔬 to capture the three different types of tears based on their origin. Beginning with tears of grief and joy, both being psychic tears 😭 triggered by extreme emotions wether positive or negative and these tears contain protein based hormones as well as the neurotransmitter “Leucine enkephalin”, a natural painkiller released when the body is under stress. Basal tears are released in t...

What’s a chemical reaction? What requirements are there for a chemical reaction to happen?

What factors affect the rate of reaction? How can we measure the rate of reaction?

In this post I will try to answer these questions. Let’s start!

A chemical reaction is a process which one or more substances, called the reactants, are

converted into one or more substances, the products. Substances are either chemical compounds

or elements. A...
