Surface Modifications on Magnesium Alloys for Biomedical Applications
Magnesium (Mg) alloys have great potential in biomedical applications due to their incomparable properties regarding other metals, such as stainless steels, Co–Cr alloys, and titanium (Ti) alloys. However, when Mg engages with body fluids, its degradation rate increases, inhibiting the complete healing of bone tissue. For this reason, it has been necessary to implement protective coatings to control the rate of degradation.

University Programmes during COVID-19 Pandemic
Within the physical sciences and other STEM-based disciplines, the need for physical, laboratory-based practical activities is essential to complement the more theoretical content associated with learning a subject. This entry reviews the transition from traditional to online/e-delivery that could be realised by educational providers when seeking to limit the spread of infection associated with viral pandemics (such as Covid-19), whilst remaining cognisant of the ability to retain a quality student learning experience and continue to achieve programme learning outcomes.

People’s Perception of Experimental Installations for Sustainable Energy
Nuclear facilities are a main milestone in the long way to sustainable energy. Beyond the well-known fission centrals, the necessity of cleaner, more efficient and almost unlimited energy reducing waste to almost zero is a major challenge in the next decades. This is the case with nuclear fusion. Different experimental installations to definitively control this nuclear power are proliferating in different countries. However, citizens in the surroundings of cities and villages where these installations are going to be settled are frequently reluctant because of doubts about the expected benefits and the potential hazards.

Chirality (Electromagnetism)
300px|thumb|The direction of current flow and induced magnetic flux follow a "handness" relationship The term chiral /ˈkaɪrəl/ describes an object, especially a molecule, which has or produces a non-superposable mirror image of itself. In chemistry, such a molecule is called an enantiomer or is said to exhibit chirality or enantiomerism. The term "chiral" comes from the Greek word for the human hand, which itself exhibits such non-superimposeability of the left hand precisely over the right. Due to the opposition of the fingers and thumbs, no matter how the two hands are oriented, it is impossible for both hands to exactly coincide. Helices, chiral characteristics (properties), chiral media, order, and symmetry all relate to the concept of left- and right-handedness.

IBM Building (Honolulu)
The IBM Building is an office building in Honolulu located at 1240 Ala Moana Boulevard. Designed by Vladimir Ossipoff, the building opened in 1962 as the Honolulu headquarters for IBM. It is presently owned by Howard Hughes Corporation, serving as a sales center for their surrounding Ward Village development. Construction of the IBM Building cost $1,500,000 (equivalent to $12,678,218 in 2019). The building was dedicated on October 10, 1962, in a ceremony attended by officials including then-Governor of Hawaii William F. Quinn. The roughly cube-shaped structure is distinguished by the honeycomb structure of its concrete brise soleil, inspired by Polynesian culture and also intended to resemble the punched cards used in the computer industry at the time of its construction. The building was slated for demolition by then-owner GGP Inc. as part of a 2008 redevelopment plan, but public backlash led to its preservation after the planned development area was purchased by Howard Hughes Corporation, which expressed an intent to maintain the IBM Building's name and general appearance. The development company instead renovated the building to use as an information and sales center for their surrounding Ward Village development.

Biophilic Design in Preschool Interiors
Modern living has made nature more and more difficult for individuals to access, but the yearning to connect with nature still exists. Children are particularly affected by this, as they have to stay indoors while separated from their parents, which is especially true for them. Biophilic design is an architectural and interior design concept that aims to bring humans closer to nature by integrating natural components into the built environment.
