A laboratory experiment reinforces the concept of acid-base equilibria while introducing a common application of spectrophotometry and can easily be completed within a standard four-hour laboratory period. It provides students with an opportunity to use advanced data analysis techniques like data smoothing and spectral deconvolution to…

A discovery-based experiment is developed depending on a "false assumption" that the students mistakenly assume they know the structure of a reaction product and are forced to reconcile observations that are inconsistent with this assumption. This experiment involves the chemistry of azulenes, an interesting class of intensely colored aromatic…

A useful metrics system for the assessment of the environmental impact of chemical processes is utilized to illustrate several of the principles of green chemistry. The use of this metrics system in conjunction with laboratory experiments in green chemistry would provide for reinforcement in both the theory and practice of green chemistry.

A laboratory project permits for the discussion of the reaction mechanism of the Suzuki-Miyaura coupling reaction. The practical part of the project makes the students familiar with working under inert atmosphere but if the appropriate equipment for working under inert atmosphere is not available in a laboratory, novel catalysts that do not…

The synthesis for CdSe quantum dot nanocrystals that vary in color and are a visually engaging way to demonstrate quantum effects in chemistry is presented. CdSe nanocrystals are synthesized from CdO and elemental Se using a kinetic growth method where particle size depends on reaction time.

An experiment is conducted for obtaining quantum dots for physical or materials chemistry. This experiment serves to both reinforce the basic concept of quantum confinement and providing a useful bridge between the molecular and solid-state world.

The finite-difference boundary-value method is a numerical method suited for the solution of the one-dimensional Schrodinger equation encountered in problems of hindered rotation. Further, the application of the method, in combination with experimental results for the evaluation of the rotational energy barrier in ethane is presented.

Monte Carlo computational experiments reveal that the ability to discriminate between first- and second-order kinetics from least-squares analysis of time-dependent concentration data is better than implied in earlier discussions of the problem. The problem is rendered as simple as possible by assuming that the order must be either 1 or 2 and that…

Scorpionate-type ligands and the original polypyrazolylborates are easy to synthesize, have good stability, and are quite user-friendly. Their thallium(I) salts are readily soluble in organic solvents that permits their use in organic media, or in two-phase aquo-organic solvent mixtures.

The chemical properties of the heaviest main-group elements often show features not found in their lighter counterparts while relativistic effects play an important role in the chemistry of these elements. The unusual properties and their relation to relativistic effects with emphasis on the new research are emphasized.

A set of sophisticated and realistic laboratory simulations is created for use in freshman- and sophomore-level chemistry classes and laboratories called 'Virtual ChemLab'. A detailed assessment of student responses is provided and the simulation's pedagogical utility is described using the organic simulation.

The ability to design and to aspire of the future design of three-dimensional molecular animations to teach molecular symmetry is an exciting outcome of computer-driven technologies. Some of the details and vital issues addressed in developing a set of Web pages to teach molecular symmetry at Imperial College London using crafted animations are…

School buses present great exposure to vehicle self-pollution. Fixed nitrogen loss in oceans is attributed to anammox. Oriented attachment allows nanowire design.

The Council of Undergraduate Research (CUR) is going to develop a new "How To" book and web page to showcase successful practices that enable faculty and institutions to design, implement, and sustain a research-supportive undergraduate curriculum. The new book volume would focus on curriculum approaches to build research skill, institutional…

A soap film and bubble festival is held in order to celebrate the National Chemistry Week. The solution to make best soap solution, bubbles and wand are explained.
