• Significance of Nanomedicines and Recent advancement in Vaccine Formulations for Combating SARS-CoV2  
  by Dheeraj Bisht, Deepak Sati, Mohammad Rashid, Rajeshwar Kamal Kant Arya 
  Abstract: Several lines of treatment for COVID-19 are being used worldwide, but to date the perfect line of therapy is not available. Nanomedicines received success rates in past in treating various viral complications like HCV, HSV1, IAV, HuNoV, IBV, EBOV and HIV1, which could be a game-changer for COVID-19. Various manufacturing units are looking towards nanotechnology and evaluating different nanomedicines and vaccines for treating corona infection. Recently Pfizer achieved great success in developing liposome-based messenger ribonucleic acid vaccine called BNT162b. There are few nanoparticles (NPs) under clinical trials capable of neutralising SARS-CoV-2 in outer surrounding, e.g. GDs-NPs (Gold nanoparticles), Ag-NPs (Silver nanoparticles), CuO-NPs (Copper oxide nanoparticles). The mutation of virus is challenging for treating COVID-19 and intense discovery in field of nanoscience and clinical manifestation of COVID-19 is required. Authors described the significant role of lipid nanoparticles (LNPs) in different vaccine formulations and their utility in nanomedicines for management of COVID-19.

• Fly Cutting Surface Profile Mathematical Model Using Kinematic Motion Errors and Cutting Parameters  
  by Bin Li, Yuanyuan Wu, Xiangyang Lei, Jianpu Xi, DongXu Ren, Zexiang Zhao 
  Abstract: This paper presents fly cutting surface profile mathematical model using the spindle and guideways kinematic motion errors, as well as cutting parameters. Surface residual height model was firstly established using the feeding velocity, cutting spindle rotational speed and tool tip radius, it indicates that the cutting depth won’t affect the surface geometric profile. Surface profile dispersion was carried out using cutter spindle rotation speed and guideways feeding velocity parameters. Guideways kinematic motion errors were introduced into the surface profile model through overlying method, and cutter spindle axial runout error was also introduced by filtering process using filtering convolution operations between the tool tip window filter and guideways kinematic overlapped surface profile. Their mathematical model expressions and illustrations were given, respectively. They were coherent with the cutting experiments results. The proposed model could be used for the surface profile prediction and machine tool error budget.
  Keywords: fly cutting; kinematic motion error; process parameters; surface profile; overlying; convolution.

• Output characteristics test of piezo-stack actuators for driving high stiffness loads with different preload  
  by Duanqin Zhang, Mingliang Li, Linpeng Dou, Jiaojiao Wang 
  Abstract: Piezo-stack actuators are widely used in micro-displacement mechanisms due to their high accuracy, small size and high output force. Analysing the output characteristics of piezo-stack actuators is an important step to ensure the high precision of micro-displacement mechanism. In this paper, a test device for output characteristics of piezo-stack actuators driving high stiffness loads is designed, and a new piezo-stack actuator preload mechanism is proposed. The simulation results verify the proposed stiffness model and dynamic model of the test device. When the same preload force was applied to the piezo-stack actuators and the frequency of driving voltage increases, the displacement amplitude of the piezo-stack actuators does not change significantly, but the hysteresis loop becomes significantly larger and the hysteresis increases. When the preload force is increased with constant voltage frequency, the output displacement of the piezo-stack actuators increases significantly at first, but decreases when the preload force exceeds a certain threshold, about 20 MPa. In this case, the hysteresis loop becomes larger and the hysteresis increases.
  Keywords: piezo-stack actuator; preload; high stiffness load; voltage loading rates.

• Study on Electrical Characteristic and Flyer Driven Ability of Al/Cu Exploding Foil  
  by Mi Zhou, Xiao-ming Ren, Qing-Ying Meng, Wei Ren, Ming Li, Hong-Zhi Yao 
  Abstract: In order to reduce the firing energy of the exploding foil blasting machine and optimised its performance, the Al/Cu exploding foil transducer element was fabricated by micro-electro-mechanical system (MEMS) technology, and its electric explosion performance and ability to drive the flyer were studied. The results showed that: when the charging voltage was 1.3 KV, the energy utilisation rate of the Al/Cu exploding foil was increased by 25% compared with the traditional Cu exploding foil. Compared with the traditional Cu explosive foil initiator, t the Al/Cu explosive foil initiator driven flyer speed is faster and the ignition sensitivity is higher.

• A Nanodata Authentication approach for a Management Middleware of NANOdevices  
  by Alberto Lopez, Jose Aguilar 
  Abstract: In this paper is presented the data authentication protocol (DAP) of the autonomic reflective middleware for the management of NANOdevices (ARMNANO) architecture, which is capable of the detection of outliers in nanodata. DAP is composed of two modules; the first one consists of typical statistical metrics on a variable, to be used in a second module based on a maximum likelihood estimation (MLE) to learn its distribution model. We found excellent results in three case studies where the context of application consisted of a nanosensor (NS) array in an epifluorescence microscope that monitors a neuromodulator, the serotonine (also called 5-hydroxytriptamine). In the first and second cases, we evaluate the top saturation point of the NS as a function of the type of NS and type of buffer, finding the zones of maximum authentication, while in the third case is assessed a time series nanodata of NS measuring 5-hydroxytriptamine in a dynamic flow system. Thus, we evaluated our nanodata authentication approach in a dynamic system with encouraging results.
  Keywords: data authentication; NANOdevices; autonomic reflective middleware; neuromodulator.
