A second perspective is defined by a self-identified group of chemical educators, faculty members and instructors who, as opposed to declaring their primary interest in a typical area of laboratory research (organic, inorganic, biochemistry, etc.), take on an interest in contributing suggestions, essays, observations, and other descriptive ...
A conoscopic interference pattern or interference figure is a pattern of birefringent colours crossed by dark bands (or isogyres), which can be produced using a geological petrographic microscope for the purposes of mineral identification and investigation of mineral optical and chemical properties.
A picture of stainless steel laboratory policeman. A policeman is generally a flexible natural-rubber blade attached to a glass rod, which is typically 5 mm to 6 mm diameter and 150 mm long. However, it also comes in various sizes and shapes depending on its uses. The rubber material provides chemical resistance.
The shield in the coat of arms of the Royal Society of Chemistry, with the seven planetary-metal symbols. The seven metals known since Classical times in Europe were associated with the seven classical planets; this figured heavily in alchemical symbolism.
Twinning is crystallographically defined by its twin plane 𝑲 𝟏, the mirror plane in the twin and parent material, and 𝜼 𝟏, which is the twinning shear direction. Deformation twins in Zr are generally lenticular in shape, lengthening in the 𝜼 𝟏 direction and thickening along the 𝑲 𝟏 plane normal. [28]
Practice research aka practice as research, practice based research or/and practitioner researcher is a form of academic research which incorporates practice in the methodology or research output. [ 1 ]
Shape of water molecule showing that the real bond angle 104.5° deviates from the ideal sp 3 angle of 109.5°. In chemistry, Bent's rule describes and explains the relationship between the orbital hybridization and the electronegativities of substituents. [1] [2] The rule was stated by Henry A. Bent as follows: [2]
1 mL and 3 mL cuvettes. Traditional ultraviolet–visible spectroscopy or fluorescence spectroscopy uses samples that are liquid. Often the sample is a solution, with the substance of interest dissolved within. The sample is placed in a cuvette and the cuvette is placed in a spectrophotometer for testing.
