Properties and Synthesis of Photocatalysts
The photocatalysts must be characterized by the ability to absorb radiation from a wide spectral range of light, the appropriate position of the semiconductor energy bands in relation to the redox reaction potentials, and the long diffusion path of charge carriers, besides the thermodynamic, electrochemical, and photoelectrochemical stabilities.

Quran Code
The term Quran code (also known as Code 19) refers to the claim that the Quranic text contains a hidden mathematically complex code. Advocates think that the code represents a mathematical proof of the divine authorship of the Quran and they also think that it can be used to identify orthographic errors within the Quranic text. Proponents of the Quran code claim that the Quran code is based on statistical procedures compared to the Bible code, which is ostensibly based on steganography. However, this claim has not been confirmed by any independent mathematical or scientific institute.

Floating Island
A floating island is a mass of floating aquatic plants, mud, and peat ranging in thickness from several centimeters to a few meters. Floating islands are a common natural phenomenon that are found in many parts of the world. They exist less commonly as an artificial phenomenon. Floating islands are generally found on marshlands, lakes, and similar wetland locations, and can be many hectares in size.

Young Hegelians
The Young Hegelians (German: Junghegelianer), or Left Hegelians (Linkshegelianer), or the Hegelian Left (die Hegelsche Linke), were a group of German intellectuals who, in the decade or so after the death of Georg Wilhelm Friedrich Hegel in 1831, reacted to and wrote about his ambiguous legacy. The Young Hegelians drew on his idea that the purpose and promise of history was the total negation of everything conducive to restricting freedom and reason; and they proceeded to mount radical critiques, first of religion and then of the Prussian political system. They rejected anti-utopian aspects of his thought that "Old Hegelians" have interpreted to mean that the world has already essentially reached perfection.

Adipose tissue in the breast
       Breast is a dynamic organ mainly composed of adipose and fibroglandular tissues. The adipose tissue extends from the collarbone to the underarm and around the center of the ribcage. Adipose tissue as an endocrine organ constantly affects the dynamics of the breast. However, the role of adipose tissue in breast has been mostly studied in terms of obesity and cancer.  In this review, we have discussed the role of breast adipose tissue in breast development from embryonic stage to mature breast. Further, we draw attention to the involvement of breast adipose tissue in pregnancy, lactation and involution associated breast changes. Finally, we depict how breast adipose tissue can affect breast cancer.

The Factors That Influence Food Waste
Food conservation is an issue of global importance. In unstable conditions such as pandemics and wars, clean plate campaigns have been developed to limit food waste around the world. The COVID-19 pandemic threatens global food security and has created an urgent need for food conservation

Built-In Car Navigation System
Driving is based on effective navigation. When using a navigation device, the user interface, the amount and quality of the underlying data and its representation all effect the quality of navigation. This study evaluates whether drivers in three different countries consider these devices to be useful and what functionality they would prefer. An online questionnaire was used to assess built-in navigation systems. The findings from 213 respondents show that current car GPSs are overloaded with features. Regardless of country, drivers simply require more basic functionality in the interface. It was also noted that the embedded functions in these devices are not fully utilized. In addition, many people use the navigation service to enter a new address while the car is moving. It may be worth examining how this option can be better implemented.

Distance Measures (Cosmology)
Distance measures are used in physical cosmology to give a natural notion of the distance between two objects or events in the universe. They are often used to tie some observable quantity (such as the luminosity of a distant quasar, the redshift of a distant galaxy, or the angular size of the acoustic peaks in the cosmic microwave background (CMB) power spectrum) to another quantity that is not directly observable, but is more convenient for calculations (such as the comoving coordinates of the quasar, galaxy, etc.). The distance measures discussed here all reduce to the common notion of Euclidean distance at low redshift. In accord with our present understanding of cosmology, these measures are calculated within the context of general relativity, where the Friedmann–Lemaître–Robertson–Walker solution is used to describe the universe.
