Biocidal Action of Hydrogen Peroxide Vapour and Mechanism
Disinfection is described as a process that eliminates many or all pathogenic microorganisms on inanimate objects, with the exception of bacterial endospores. Disinfection is usually carried out by chemical or physical means. Among other settings, disinfection is of utmost importance in hospital environments due to pathogens living on hospital surfaces being the direct cause for hospital-acquired infections (HAIs). However, the presence of a wide range of pathogens and biofilms, combined with the indiscriminate use of antibiotics, presents infection control teams in healthcare facilities with ongoing challenges in the selection of biocides and application methods. This necessitates the development of biocides and innovative disinfection methods that overcome the shortcomings of conventional methods. The use of hydrogen peroxide vapour to be a superior alternative to conventional methods. Hydrogen peroxide vapour to be very close to an ideal disinfectant due to its proven efficacy against a wide range of microorganisms, safety to use, lack of toxicity concerns and good material compatibility.

Continuum Robots and Magnetic Soft Robots
Magnetic soft robots, as an innovative branch of the soft robotics discipline, are eye-catching because of their excellent controllability and high flexibility under the control of magnetic fields. Thanks to the properties of magnetic materials, this type of robot can be manufactured into extremely fine micro guide wires, making it particularly applicable in fields such as minimally invasive pipeline interventional treatment or interventional laser surgery. Although magnetic soft robots and continuum robots belong to the same category of soft robots, they show obvious differences and complementarities in design concepts, application scenarios, and technical implementation. Especially from the perspective of structural size, continuum robots have encountered certain challenges in miniaturization, and magnetic soft robots can be regarded as an important expansion and deepening of continuum robots in terms of size reduction.

Micro-Arc Oxidation in Titanium and Its Alloys
Titanium (Ti) and its alloys are widely recognized as preferred materials for bone implants due to their superior mechanical properties. However, their natural surface bio-inertness can hinder effective tissue integration. To address this challenge, micro-arc oxidation (MAO) has emerged as an innovative electrochemical surface modification technique. Its benefits range from operational simplicity and cost-effectiveness to environmental compatibility and scalability. Furthermore, the distinctive MAO process yields a porous topography that bestows versatile functionalities for biological applications, encompassing osteogenesis, antibacterial, and anti-inflammatory properties.
