TL;DR: Nanotechnology opens up new possibilities for food innovation at an incredible rate, yet new technology needs evaluations of both potential negative impacts and numerous good effects as discussed by the authors , which is why it is important to evaluate the potential negative impact and potential good effects.
Abstract: Nanotechnology opens up new possibilities for food innovation at an incredible rate, yet new technology needs evaluations of both potential negative impacts and numerous good effects. We aimed to cover some of the latest breakthroughs in nanotechnology and their application to food processing in this overview. Applications of nanoparticles in the food sector are growing rapidly. Nanoparticles (NPs) play a significant role in enhancing food quality by protection and preservation and are preferred over traditional preservatives. In this work on organic and inorganic nanoparticles in various forms such as single and multiple metal oxides, polymeric nanocomposite, nanocapsules, etc., as well as various methods of their preparations are discussed. Nanoparticles in food are currently most explored for their antimicrobial applications; factors affecting their antimicrobial potential, their antimicrobial mechanisms, and laboratory methods applied to evaluate antimicrobial potentials are also discussed. Various properties of NPs in relevance to antimicrobial activities and methods used for their characterization are also discussed. Antimicrobial NPs used for the purpose in various ways such as active packaging, mixed in food, incorporated in edible film and coating, etc. discussed. In the current state NPs used in the food industry, have various concerns such as safety, and regulatory policies relevant to preparing, processing, packaging, and consumption are discussed. NPs do possess some functional properties and harmful effects as well in this relevant future perspective of antimicrobial NPs in food and their other applications explored in current work. Various aspects of the most intensively studied NPs as an antimicrobial in food technology such as silver oxide, and zinc oxide, are discussed.

TL;DR: The proposed plan, the cloud confirms the realness of the arrangement without knowing the client's character before putting away information, has the included element of access control in which just legitimate clients have the capacity to decode the put away data.
Abstract: They propose another decentralized access control plan for secure information stockpiling in mists that backings unknown verification. In the proposed plan, the cloud confirms the realness of the arrangement without knowing the client's character before putting away information. Our plan additionally has the included element of access control in which just legitimate clients have the capacity to decode the put away data. The plan forestalls replay assaults and bolsters creation, change, and perusing information put away in the cloud. We additionally address client repudiation. Besides, our validation and access control plan is decentralized and powerful, not at all like different access control plans intended for mists which are brought together. The correspondence, calculation, and capacity overheads are similar to brought together approaches.
TL;DR: In this paper , the potential use of ultrashort laser pulse processing of NPs and NPs-based thin films is discussed, with a focus on femtosecond laser pulses.
Abstract: The unique shape and size dependant properties of nanoparticles (NPs) are responsible for their emerging, extensive applications in everyday industry. The application of NP inks for printed flexible electronics requires an additional post processing step since the presence of additives and stabilizers in the NP based inks often results in inferior electrical properties of the printed patterns. Laser sintering is a well-established technique for past number of years and is extensively used with continuous wave (CW), long, and short pulsed lasers. The literature is enriched with conventional sintering methods however the field of ultrashort laser sintering is relatively under-reported compared to CW laser and nanosecond laser-based techniques. This study concisely focuses on the potential use of ultrashort laser pulse processing of NPs and NP based thin films. The review provides the recent advances on ultrashort lasers sintering with a key focus on femtosecond laser pulses. • The review presents a study of nanoparticles (NPs), their deposition and post processing techniques with a key focus on ultrashort laser sintering. • NPs and NPs based thin films are discussed. • Role of ultrashort pulses in laser sintering, laser crystallization and laser annealing is discussed. • Potential to use two-temperature phenomenon in thin film laser processing.
TL;DR: In this article , the authors examined whether occupational stress mediated the relationship between abusive supervision and well-being of nursing staff and found that abusive supervision was positively associated with occupational stress and negatively associated with employee wellbeing.
Abstract: AIM The study examined whether occupational stress mediated the relationship between abusive supervision and well-being of nursing staff. DESIGN A cross-sectional questionnaire survey was administered. METHODS Data were collected at three-time points between July 2020 and January 2021. A total of 313 valid responses were obtained from nurses working in a general hospital in Taiwan. The data were analysed using descriptive statistics, Pearson's correlation analysis and the bootstrap method. RESULTS Abusive supervision was positively associated with occupational stress (β = 0.288, SE = 0.069, 95% CI [0.152, 0.423]) and negatively associated with employee well-being, including psychological (β = -0.350, SE = 0.084, 95% CI [-0.515, -0.186]), physical (β = -0.301, SE = 0.080, 95% CI [-0.459, -0.143]) and social well-being (β = -0.422, SE = 0.121, 95% CI [-0.661, -0.183]). Occupational stress was negatively related to employee well-being. A mediation analysis with bootstrapping revealed that occupational stress mediated the relationship between abusive supervision and employee well-being, which included psychological (95% bootstrap CI [-0.183, -0.046]), physical (95% bootstrap CI [-0.212, -0.062]) and social well-being (95% bootstrap CI [-0.178, -0.040]). CONCLUSION Abusive supervision influences employee well-being. Occupational stress mediates the relationship between abusive supervision and employee well-being. To improve employee well-being, hospital administrators should develop policies for effectively managing nursing supervisors' abusive behaviour and subordinates' stress management. IMPACT Abusive supervision increased the occupational stress of employees and influenced their well-being. Thus, educational courses should be implemented to train supervisors to practice positive leadership and treat employees fairly. Promoting stress management among nursing staff may lead to the prompt reporting of abusive events and improved employee well-being. NO PATIENT OR PUBLIC CONTRIBUTION This study investigated the relationship between the abusive supervision and employee well-being of nursing employees. No patient or public contribution is involved in this study.
TL;DR: In this article , a pH-responsive self-gated antibacterial material is reported, which uses mesoporous silica nanomaterials as a carrier and achieves selfgating of the antibacterial agent through pH-sensitive imine bonds.
Abstract: In recent years, silica nanomaterials have been widely studied as carriers in the field of antibacterial activity in food. Therefore, it is a promising but challenging proposition to construct responsive antibacterial materials with food safety and controllable release capabilities using silica nanomaterials. In this paper, a pH-responsive self-gated antibacterial material is reported, which uses mesoporous silica nanomaterials as a carrier and achieves self-gating of the antibacterial agent through pH-sensitive imine bonds. This is the first study in the field of food antibacterial materials to achieve self-gating through the chemical bond of the antibacterial material itself. The prepared antibacterial material can effectively sense changes in pH values caused by the growth of foodborne pathogens and choose whether to release antibacterial substances and at what rate. The development of this antibacterial material does not introduce other components, ensuring food safety. In addition, carrying mesoporous silica nanomaterials can also effectively enhance the inhibitory ability of the active substance.
