Aqueous Zinc-Ion Batteries and Flexible Zinc-Ion Batteries
Lithium-ion batteries (LIBs) have been considered an easily accessible battery technology because of their low weight, cheapness, etc. Unfortunately, they have significant drawbacks, such as flammability and scarcity of lithium. Since the components of zinc-ion batteries are nonflammable, nontoxic, and cheap, aqueous zinc-Ion batteries (AZIBs) could be a suitable replacement for LIBs.

Biochemical-Modification of Titanium Oral Implants
Biochemical Modification of Titanium Surfaces (BMTiS) is the process that immobilize proteins, enzymes, or peptides on biomaterials for the purpose of inducing specific cell and tissue responses or, in other words, to control the tissue implant interface with molecules delivered directly to the interface. Biochemical surface modification utilizes critical organic components of bone to affect tissue response. The purpose of implant surface functionalization by BMTiS derives from the supposition that the ability to imitate bone tissue’s characteristics may increment implant surface performances, thus promoting the initial biological response. Therefore BMTiS, strictly speaking, refers only to the use of molecules normally present in the human body.

Resistive-Based Gas Sensors Using Pristine Quantum Dots
Quantum dots (QDs) are used progressively in gas sensing applications because of their special electrical properties resulting from their extremely small size. QDs show a high sensing performance at generally low temperatures owing to their extremely small sizes, making them promising materials for the realization of reliable and high-output gas-sensing devices. This article discusses the gas sensing features of QD-based resistive sensors. Different types of pristine QD gas sensors for the detection of various gases are discussed in this article.

Photocatalytic Oxidation of Methane to Methanol
Methane is one of the promising alternatives to non-renewable petroleum resources since it can be transformed into added-value hydrocarbon feedstocks through suitable reactions. The conversion of methane to methanol with a higher chemical value has recently attracted much attention. The selective oxidation of methane to methanol is often considered a “holy grail” reaction in catalysis. However, methanol production through the thermal catalytic process is thermodynamically and economically unfavorable due to its high energy consumption, low catalyst stability, and complex reactor maintenance. Photocatalytic technology offers great potential to carry out unfavorable reactions under mild conditions. Many in-depth studies have been carried out on the photocatalytic conversion of methane to methanol.

Bacterial Cellulose for Wound Dressing Application
Chronic ulcers are among the main causes of morbidity and mortality due to the high probability of infection and sepsis and therefore exert a significant impact on public health resources. Numerous types of dressings are used for the treatment of skin ulcers-each with different advantages and disadvantages. Bacterial cellulose (BC) has received enormous interest in the cosmetic, pharmaceutical, and medical fields due to its biological, physical, and mechanical characteristics, which enable the creation of polymer composites and blends with broad applications. In the medical field, BC was at first used in wound dressings, tissue regeneration, and artificial blood vessels. This material is suitable for treating various skin diseases due its considerable fluid retention and medication loading properties. BC membranes are used as a temporary dressing for skin treatments due to their excellent fit to the body, reduction in pain, and acceleration of epithelial regeneration. BC-based composites and blends have been evaluated and synthesized both in vitro and in vivo to create an ideal microenvironment for wound healing.

Contaminant Cocktails of High Concern in Honey
Environmental pollution is a crucial problem in our society, having a better understanding of its consequences, which include the increase of contaminant cocktails present in the environment. The contamination of honeybees can occur through their interaction with the nearby environment. Therefore, if honeybees are previously contaminated, there is a possibility of contamination of their products, such as honey as natural, or minimally processed, product, resulting from the honeybees’ activity.

Metal-Promoted Heterocyclization
The recent formulation, production, and ongoing administration of vaccines represent a starting point in the battle against SARS-CoV-2, but they cannot be the only aid available. In this regard, the use of drugs capable to mitigate and fight the virus is a crucial aspect of the pharmacological strategy. Among the plethora of approved drugs, a consistent element is a heterocyclic framework inside its skeleton. Heterocycles have played a pivotal role for decades in the pharmaceutical industry due to their high bioactivity derived from anticancer, antiviral, and anti-inflammatory capabilities. In this context, the development of new performing and sustainable synthetic strategies to obtain heterocyclic molecules has become a key focus of scientists.

Cell Penetrating Peptides
Cell-penetrating peptides (CPPs) are peptides that can directly adapt to cell membranes and then permeate into cells. They are usually cationic for the electronic interactions between CPPs and anionic cell membrane. Meanwhile, some of them can target a specific protein at the same time. In nanomedicine, as an element, CPPs are usually covalently linked to the surface of nanocarriers to endow their permeability to the whole system.
