Mathematical modeling plays an important role in studying the glucose-responsive behavior of chemically-controlled closed-loop system for design and optimization. In this study, a glucose-responsive swelling model controlled by seven main equations was established and solved to investigate the glucose-responsive behavior of Con A-DexG hydrogel-based chemically-controlled closed-loop system. The swelling ratio Q and diffusion coefficient D are two variables in the model, and they can help design the molecular
structure of the hydrogel (i.e., a mixture of Con A and DexG) with a potential to design a personalized insulin delivery system......

Bioengineering synthetic materials to replace some specific
human functions is the inevitable direction of development
in the field of materials in the near future. Synthetic materials
containing living cells will have a broad application prospect in
skin replacement. For example, the market scale of wound repair
(avoiding donor site injury, promoting healing, and improving
healing quality), such as in vitro validation of beauty products will
be 10 billion US dollars. Up to now, in the research of skin substitute
materials, many research teams around the world have released a
lot of research results, but they still have not fully developed an
artificial composite material that can replace human skin......

The pure zirconia has three different crystal structures: monoclinic, m-ZrO2 , tetragonal, t-ZrO2 , and cubic, c-ZrO2 [1]. The crystal structures are shown in (Figure 1) At room temperature, ZrO2 is in a monoclinic phase. The phase transition from m-ZrO2 to t-ZrO2 takes place at about 1,447 K. Above 2,650 K, the t-ZrO2 transforms to c-ZrO2 , which is stable up to the melting point at 2,950 K. The c-ZrO2 has an ideal fluorite structure (shown in (Figure 1a). The Zr cations are situated in a face-centered cubic (fcc) lattice, i.e. at the corners of the cubic elementary cell as well as at the halves of the [110] directions. The oxygen anions lie at the quarters of [111] directions, which are the tetrahedral interstitial sites associated with this fcc lattice. The space group is O5 h or Fm3 m. In this structure, each Zr cation is coordinated .....

A Chemosensors is a substance capable of changing color or
signal in absorption or emission spectra in the presence of certain
specific species with definite concentration which indicate its
presence or absence. The information is obtained in the form of a
measurable physical signal that is linked with the certain chemical
species concentration called analyte [1]. The chemosensors may be
broadly classified into two categories.
1. Cation’s sensors
2. Anion’s sensors
Cation Sensors
Optical cation sensing was initially started for metal ions not
having its own spectra in the visible region, has been broadly
studied. With the better understanding of host-guest chemistry of
crown ethers, it became easier to develop chromogenic sensors for
metal ions. Later many outstanding examples of chromophoric and
fluorophoric receptors .....

Lamotrigine belongs to a class of phenyltriazine compounds, chemically unrelated to other anticonvulsants [1]; used to control seizures and convulsions of various grades [2]. The antiepileptic effect of LTG entails from its binding with the voltage gated sodium channels (VNaC) and thus inhibiting the release of endogenous amino acids and acetylcholine [3,4]. Schiff bases of antiepileptic drugs protect against seizures through variety of cellular targets, like synaptic vesicle protein, neurotransmitter metabolic enzyme, neurotransmitter transporter and ion channels [5]. A homology model of VNaC was prepared for molecular docking studies of lamotrigine [6]. Docking of metal derived schiff base ligand is a new approach in computational chemistry; it predicts the binding affinity of small molecules with receptor that results in new complex wi.....

Mg-Li alloy is the lightest nontoxic metallic alloy. Due to extremely low density, excellent specific stiffness, good specific strength, good damping property, and electromagnetic shielding performance, Mg-Li alloy has the potential for applications in aerospace, military weapons, 3C products, and automobile manufacturing fields. Thus, study on Mg-Li alloy has drawn much attention from extensive researchers [1-7]. Not only room temperature mechanical properties, corrosion performance, and microstructures [1,4,5,6] but also high temperature behavior and microstructure [2,3,7] were investigated. Because of good comprehensive mechanical properties of two-phase Mg-Li alloys, we designed an Mg-8Li-2Al-2Zn (designated as LAZ822) alloy. The purpose of 8 wt. %Li addition is to obtain a two-phase alloy. The purpose of 2 wt.% Al addition is to achi.....

The performance of single material has been difficult to meet the increasingly complex working conditions due to its own limitations, so the composite material is applied. The composite structure of heterogeneous materials not only has the advantages of various materials, but also can be used normally even under extremely harsh working conditions. At the same time, it can also replace the use of scarce materials to a certain extent and reduce costs, which has a very broad application prospect [1,2]. Such as ceramic, protonic ceramic fuel cells can directly use both hydrogen and hydrocarbon fuels to produce electricity at potentially more than 50 per cent efficiency [3,4]. Ceramics are also applied and reported as restorative materials for treatment of severe tooth wear and bearing was introduced in total hip arthroplasty due to its proper.....

For Electromagnetic (EM) Weapons approach, this author suggests that one should look at Longitudinal Scalar Wave (LSW) or Pressure Wave as a newly developed weapon in future directed energy warfare and take advantage of such innovative approach. Additionally, besides the only weapon application of this wave, we can have biomedical applications of such pressure wave at a lower frequency. Even the LSW at low frequency can produce cheap energy by taking advantage of Deuterium + Deuterium Fusion interaction, where we can reduce or lower the nuclear potential barrier, consequently, make the fusion of D+D to take place at a lower temperature. Similarly, this wave at certain frequency can be used for under-water communication, where submarine communities or special warfare group of any modern navy can utilize it. With this short review, it can b.....

Membrane separation technology holds a key role across various research areas and disciplines ranging from water desalination and purification systems to fuel cell technologies. Basically, membrane is a thin material which separates mass by selective transportation of one species of a mixture through it, while retaining other species behind. This ability to regulate permeation, has made membrane technology appealing in different mass separation applications. However, throughout membrane technologies, there are hurdles to overcome to achieve an optimal membrane such as a tradeoff between permeability and selectivity, and a need for more robust materials [1-3]. In this regard, graphene membranes offer tremendous potentials for use in membrane technologies. Graphene membrane is only one or few atoms thick, but it possesses excellent mechanic.....

Residual stresses are those stresses that remain in an object (in particular, in a welded component) even in the absence of external loading or thermal gradients. In some cases. residual stresses result in significant plastic deformation, leading to warping and distortion of an object. In others, they affect susceptibility to fracture and fatigue. Welding is considered a highly complex metallurgic process that results in irregular geometries, material inadequacies/flaws and tensile residual stresses. High tensile residual stresses and stress concentrations resulting from the weld process have a significant impact on fatigue life of structures, and thus a topic of great concern product design. This paper investigates the prediction of residual stresses developed in shielded metal arc welding of high thickness DH32 (ASTM A131) steel plates .....

Currently, besides semiconductor manufacturing, ion implantation is used for many other purposes, e.g., sensor manufacturing, hardening of metal surfaces, friction modification, chemical resistance alteration, painting and many others. Most of turnover in the industry (about 70% is made by research driven MEs), thus the new generation of implanters ought to be user friendly to highly flexible and small-scale production in small size enterprises. The development history of ion sources in detail can be found in [1]. The [2] discusses advantages and weakness between ion sources. Due to extremely low volatility with melting point at 2076°C and boiling point at 3927°C [3] the development of Boron ion source is a technological challenge. Since early 1960’s various boron containing molecules were investigated until boron rifluoride gas (BF3,.....

The future of the car is in electrification, electrification is still in its infancy, in relation to the experience that exists with internal combustion engines, but also have a major environmental disadvantage as well as for the production of electricity, in various countries carried out with the use of oil with the combustion of lignite, this has as a consequence the burden on the environment. My research proposal is based on the philosophy that with e-mobility begins a new ecological era, on the one hand cannot create ecological cars and on the other hand to burden the environment for the increasing use of energy that will be required when it growsThe use of a servo mechanism, ie a slow tuning tuner, will be able to start a power generating mechanism, ie a generator, this tuner will be in the charging place of the cars, ie the refuelin.....

Electromagnetic sheet forming is a high-velocity process that the strain rate is considerable. The formability of the material increased in the high strain rate process. In this study, an Al/Cu two- layer sheet’s formability at a high strain rate is investigated using electromagnetic forming. The two-layer sheet produced by the explosive method was used to create different geometry and different strain states in the experimental test. The necking strain was extracted by griding the sheet. The coil is designed to create enough pressure to reach the fracture in the sheet. The driver sheet is also used to create more pressure on the workpiece. The displacement of the sheet and the strain distribution were investigated in a different geometry with different widths. The magnetic pressure is 19% higher in the CA lay-p (Cu near the coil and Al.....
