Silver Nanoparticles as Anti-Infectious Regents
Silver is easily available and known to have microbicidal effect with wide antibacterial spectrum due to its silver ions mainly; moreover, it does not impose any adverse effects on the human body. Furthermore, the development of multidrug-resistant bacteria, as in the case of antibiotics, is less likely. Recently, silver nanoparticles (Ag NPs) have been synthesized and revealed its anti-viral activity. Because of their characteristics, Ag NPs are useful countermeasures against infectious diseases, which constitute a major issue in the medical field. Therefore, Ag NPs could expect to apply to materials preventing healthcare workers (HCWs), not only patient, from various infection.

Conducting Silicone-Based Polymers
Conducting polymers (CPs) are unique due to their ease of synthesis, environmental stability, and simple doping/dedoping chemistry. Electrically conductive silicone polymers are the current state-of-the-art for, e.g., optoelectronic materials.

Developing Edible Starch Film Used for Packaging Seasonings
Edible starch-based film was developed for packaging seasoning applied in instant noodles. The edible film can quickly dissolve into hot water so that the seasoning bag can mix in the soup of instant noodles during preparation.

Stereoselective Synthesis of Chiral Molecules
Metal/lipase-combo catalyzed dynamic kinetic resolution (DKR) of racemic chiral alcohols is a general and practical process to obtain the corresponding enantiopure esters R with quantitative conversion. The use of known Ru-catalysts as well as newly developed homogeneous and heterogeneous metal catalysts (Fe, V) contributed to make the DKR process more sustainable and to expand the substrate scope of the reaction. In addition to classical substrates, challenging allylic alcohols, tertiary alcohols, C1-and C2-symmetric biaryl diols turned out to be competent substrates. Synthetic utility further emerged from the integration of this methodology into cascade reactions leading to linear/cyclic chiral molecules with high ee through the formation of multiple bonds, in a one-pot procedure.

Canada's Food Guide
Canada's Food Guide (French: Guide alimentaire canadien) is a nutrition guide produced by Health Canada. In 2007, it was reported to be the second most requested Canadian government publication, behind the Income Tax Forms. The Health Canada website states: "Food guides are basic education tools that are designed to help people follow a healthy diet."

Green Tea Catechins
Green tea and green tea catechins have been shown to be strongly inhibitory to cancer formation in rodents. They are believed to do this by altering cells after they have been initiated on the path toward cancer. Green tea and green tea catechin prevention of cancer in humans has been hard to detect. We discuss that the reason for this difference is likely to be the digestive tract microbiome. If green tea catechins are to be continue to be tested for cancer prevention properties in humans it will be necessary to take into account variable digestive tract microbiome metabolism in people so the dose can be optimized for each person thus avoiding toxicity.

Hyperchloremia
Hyperchloremia is an electrolyte disturbance in which there is an elevated level of chloride ions in the blood. The normal serum range for chloride is 96 to 106 mEq/L, therefore chloride levels at or above 110 mEq/L usually indicate kidney dysfunction as it is a regulator of chloride concentration. As of now there are no specific symptoms of hyperchloremia; however, it can be influenced by multiple abnormalities that cause a loss of electrolyte-free fluid, loss of hypotonic fluid, or increased administration of sodium chloride. These abnormalities are caused by diarrhea, vomiting, increased sodium chloride intake, renal dysfunction, diuretic use, and diabetes. Hyperchloremia should not be mistaken for hyperchloremic metabolic acidosis as hyperchloremic metabolic acidosis is characterized by two major changes: a decrease in blood pH and bicarbonate levels, as well as an increase in blood chloride levels. Instead those with hyperchloremic metabolic acidosis are usually predisposed to hyperchloremia. Hyperchloremia prevalence in hospital settings has been researched in the medical field since one of the major sources of treatment at hospitals is administering saline solution. Previously, animal models with elevated chloride have displayed more inflammation markers, changes in blood pressure, increased renal vasoconstriction, and less renal blood flow as well at glomerulus filtration, all of which are prompting researchers to investigate if these changes or others may exist in patients. Some studies have reported a possible relationship between increased chloride levels and death or acute kidney injury in severely ill patients that may frequent the hospital or have prolonged visits. There are other studies that have found no relationship. As studies continue, it is important to include a large patient sample size, a diverse patient population, and a diverse range of hospitals involved in these studies.

Tin-Based Perovskite Solar Cells, Dopants
Tin-based perovskite solar cells exist in p-i-n or n-i-p configurations alternating the position of the electron transport (n) and hole transport layer (p). Therefore, during fabrication of these layered devices, it is very common to encounter energy level mismatches and defects at the interface. The simplest trick to improve the performance of tin-based perovskite solar cells is to add an interfacial layer to minimise the energy mismatch and defects at interfaces.

Electrochemical Sensors for Bromate Determination
Potassium bromate (KBrO3), a renowned oxidizing agent, has a huge reputation for being one of the best and least expensive dough-improving substances in the baking industry. As such, its importance in the baking industry cannot be overemphasized. KBrO3 produced the desired result in baking by influencing the physical and chemical properties of macromolecules such as protein and starch often found in the dough. Precisely, the viscosity, extent of gelatinization, swelling characteristics of the dough, and disulfide linkage formation (in gluten proteins) are affected by the use of KBrO3 as an additive in bread baking. Bromate has been found to be a product of water treatment due to bromide ion oxidation that occurs during ozonation.

Cellulose Coarse-Grained
Cellulose is the most common biopolymer and widely used in our daily life. Due to its unique properties and biodegradability, it has been attracting increased attention in the recent years and various new applications of cellulose and its derivatives are constantly being found. The development of new materials with improved properties, however, is not always an easy task, and theoretical models and computer simulations can often help in this process.
