Solvent Extraction and SeparationScienceIntroductionSolvent extraction and separation science is a branch of chemistry that deals with the extraction of specific substances from a mixture using a liquid solvent. This process involves the use of different solvents and techniques to separate substances based on their physical and chemical properties. Solvent extraction has applications in various fields such as mining, pharmaceuticals, and the environment. In this article, we will look at the principles of solvent extraction and its applications.Principles of Solvent ExtractionThe principle of solvent extraction is based on the concept of like dissolves like. This means that substances that have similar chemical properties will dissolve in each other. The process of solvent extraction involves the use of chemical agents known as solvents to dissolve and separate a substance from a mixture. The solvent must be chosen carefully, based on the physical and chemical properties of the substance being extracted. Solvents can be polar or non-polar, and the choice of solvent plays a critical role in the efficiency of the extraction process.Application in MiningSolvent extraction has a wide range of applications in the mining industry. It is commonly used to extract metals such as gold, copper, and silver from ores and concentrates. In gold mining, cyanide is often used as a solvent to extract gold from its ore. The process involves dissolving the gold in a cyanide solution, which is then separated from the ore.Solvent extraction is also used to extract impurities from metals during the refining process. For instance, copper refining involves electrorefining, which is a process used to remove impurities from copper. The process involves placing the impure copper in asolution and passing an electric current through the solution. This causes the pure copper to collect on an electrode, while the impurities settle at the bottom. Solvent extraction is then used to extract the impurities from the solution.Application in PharmaceuticalsSolvent extraction has significant applications in the pharmaceutical industry. It is used to extract active ingredients from plant and animal tissues, which are then used to make drugs and medicines. For example, morphine, which is a painkiller, is extracted from the opium poppy using solvent extraction. Similarly, quinine, which is used to treat malaria, is obtained from the bark of the cinchona tree using solvent extraction.Solvent extraction is also used in the purification of drugs. For instance, penicillin, an antibiotic, is initially extracted from the mould using a solvent. However, the extract contains impurities and other unwanted substances. Solvent extraction is then used to isolate the pure drug from the impurities.Application in the EnvironmentSolvent extraction has significant applications in the environment. It is used to remove toxic substances from polluted soil and water. For example, organic compounds such as benzene, toluene, and xylene, which are known to be toxic to humans, can be removed from contaminated water using solvent extraction. The process involves using an organic solvent to dissolve the toxic compounds. The solvent is then separated from the water, leaving behind a purified sample.ConclusionSolvent extraction and separation science is an essential branch of chemistry that has various applications in different fields. The process involves the use of chemical agents known as solvents to dissolve and separate substances from a mixture. Solvent extraction has applications in mining, pharmaceuticals, and the environment. It plays a critical role in the extraction of metals from ores, the extraction and purification of drugs, and the removal of toxic substances from polluted water. Solvent extraction is a crucial process that helps to improve the quality of life for people in different parts of the world.。
扭曲分子内电荷转移的英文全称The phenomenon of charge transfer within molecules can be quite complex, and when it occurs in a distorted manner, itis referred to as "Torsional Charge Transfer" in thescientific community.This process involves the movement of electrons from one part of a molecule to another, often resulting in a change in the molecule's overall charge distribution. It plays apivotal role in various chemical reactions and the behavior of materials.Torsional Charge Transfer is characterized by therotation of certain molecular bonds, which can lead to an altered electronic structure. This can be observed in many organic compounds and is studied extensively in the field of quantum chemistry.Understanding the mechanisms of Torsional Charge Transfer is crucial for the development of new materials with specific electronic properties, such as semiconductors and organic conductors.In molecular systems, the degree of distortion and the subsequent charge transfer can significantly influence the molecule's reactivity and stability. Researchers are continuously exploring the relationship between these factors to enhance our knowledge of molecular interactions.The study of Torsional Charge Transfer also has implications in the design of pharmaceuticals, where the electronic properties of drug molecules can affect their efficacy and safety.Moreover, this concept is not limited to organic chemistry; it is also applicable in the realm of inorganic compounds, where the transfer of charges can lead to unique physical and chemical properties.In summary, Torsional Charge Transfer is a fundamental concept in chemistry that helps us understand the behavior of molecules under various conditions and contributes to advancements in material science and pharmaceuticals.。

静电成像方式英语作文Title: The Principle and Applications of Electrostatic Imaging。
Electrostatic imaging, a technique utilized in various fields including medical diagnostics, security screening, and scientific research, relies on the manipulation of electrostatic forces to generate images. This essay delves into the principle behind electrostatic imaging, its applications, and the advancements in this technology.### Principle of Electrostatic Imaging。
Electrostatic imaging operates on the fundamental principle of electrostatic attraction and repulsion. It involves the creation of an electric field between acharged object and a grounded substrate. When an object is charged, the electric field interacts with nearby particles, causing redistribution of charges and resulting invariations in the electric potential across the surface. Bymeasuring these potential differences, an image of theobject's surface or internal structure can be reconstructed.### Components of Electrostatic Imaging Systems。

a rXiv:h ep-ph/22183v119Fe b22Extraction of the neutron charge form factor from the charge form factor of deuteron A.F.Krutov ∗Samara State University,443011,Samara,Russia V.E.Troitsky †D.V.Skobeltsyn Institute of Nuclear Physics,Moscow State University,119899,Moscow,Russia February 19,2002Abstract We extract the neutron charge form factor from the charge form factor of deuteron obtained from T 20(Q 2)data at 0≤Q 2≤1.717(GeV 2).The extraction is based on the relativistic impulse approximation in the instant form of the relativistic Hamiltonian dynamics.Our results (12new points)are compatible with existing values of the neutron charge form factor of other authors.We propose a fit for the whole set (35points)taking into account the data for the slope of the form factor at Q 2=0.Keywords:Relativistic model;Deuteron;Neutron charge form factor PACS:13.40.Gp;14.20.Dh;24.10.JvThe behavior of the neutron charge form factor G n E (Q 2),(Q 2=−q 2,q -the momentum transfer)is of great importance for the understanding of the electromagnetic structure of nucleons and nuclei.However,G n E (Q 2)is still known rather poorly.As there are no free neutron targets,G n E (Q 2)has to be extracted from the data for composite nuclei,for example deuteron or 3He [1,2,3,4,5,6,7,8,9,10,11,12,13].The direct measurement of great precision (≃1.5%)is possible only for the slope dG n E (Q 2)/dQ 2at Q 2=0,as determined by thermal neutron scattering [14].While obtaining the information about the neutron from the scattering data on compos-ite systems one encounters two kinds of difficulties.First,the results depend crucially on the model for NN interaction [13,15,16].Second,there exists a dependence on the rel-ativistic effects,exchange currents,nucleon isobar states,final state interaction in inelastic channels etc.[4,12].The use of polarized beams and polarized targets in recent experiments diminishes uncertainties due to those effects [3,4,5,7,8,9,11,13].In the present paper the neutron charge form factor is extracted from the experimental data on the deuteron charge form factor obtained through polarization experiments on elastic ed scattering [17,18,19].In the JLab experiments [19]the deuteron charge form factor is obtained up to Q 2=1.717(GeV 2).In this range of momentum transfer the theoretical description of the polarization tensor T 20(Q 2)depends essentially on the choice of the form of NN interaction and relativistic approach is required.Our calculations are based on the method of relativistic Hamiltonian dynamics (RHD)which is widely used in present time.One can find the description of RHD method in the reviews [20]and especially the case of the deuteron in the reviews [21],[22]).We use our own variant [23],[24]of the instant form of RHD.This variant permits to take correctly into account the relativistic effects in the elastic ed scattering in the relativistic impulse approximation [25].The main point of our approach is the construction of the electromagnetic–current operator for the system of interacting particles.In our approach this operator is Lorentz covariant and satisfies the conservation law.Let us note that,as far as we know,it is for the first time that the neutron charge form factor is determined from an analysis of the deuteron charge form factor.In our approach in the relativistic impulse approximation the following equation for the deuteron charge form factor takes place (see [25]for details):G C (Q 2)=G CC (Q 2)G p E (Q 2)+G n E (Q 2) +G CM (Q 2) G p M (Q 2)+G n M (Q 2) .(1)Here G p,n E,M are charge and magnetic form factors of proton and neutron.The fact that nucleons magnetic form factors enter the Eq.(1)is due to the relativistic effect.The functions G CC ,G CM in (1)are given by:G CC (Q 2)= l,l ′d √s ′ϕl (s )g ll ′CC (s ,Q 2,s ′)ϕl ′(s ′),(2)G CM (Q 2)= l,l ′d √s ′ϕl (s )g ll ′CM (s ,Q 2,s ′)ϕl ′(s ′),(3)here ϕl (s )is the wave function in the sense of RHD (see [20,23,24]):ϕl (s )=4√2√M is the nucleon mass,l=0,2–the nucleon angular momentum in the deuteron,u l(k)–the wave function for the model NN interaction.The functions g ll′CC,g ll′CM are given by the following equations(5)–(10)(note that the same equations were obtained independently in[26]):g ll′CC(s,Q2,s′)=R(s,Q2,s′)(s+s′+Q2)Q2a ll′(s,Q2,s′),(5)g ll′CM(s,Q2,s′)=12cosω1cosω2+16√2L1cosω1cosω2+112L3sinω1sinω2 ,b00= 16sinω1cosω2 ,b02=12(P′22+2P′20)sinω1cosω2, b22=− −124L2cos(ω2−ω1)+1[λ(s,−Q2,s′)]3/211+Q2/4M2,ξ(s,Q2,s′)=3P21P′21+1M (√s′)2+Q2 +√s+√M(s+s′+Q2)α(s,s′)+√s+√2 3z2−1 ,P21(z)=3z√s(s′−s−Q2)λ(s,−Q2,s′)(s−4M2),z′=z′(s,Q2,s′)=−z(s′,Q2,s).(9)ϑ(s,Q2,s′)=θ(s′−s1)−θ(s′−s2),θis the step function.s1,2=2M2+12M2G CC(Q2)−G CM(Q2)1The details will be published elsewhere.wave functions[31]were obtained in the frame of the potentialless approach to the inverse scattering problem(see for the details[38]).They are given by the dispersion type integral directly in terms of the experimental scattering phases and the mixing parameter for NN scattering in the3S1−3D1channel.In the Eq.(12)we use for the nucleon form factors G p E(Q2),G p M(Q2),G n M(Q2)one (with the bestχ2)of thefits of the recent paper[39]–DRN–GK(3).The results of our calculations of the neutron charge form factor in the points where the deuteron charge form factor is measured are given in the Table1(see also Fig.2).The accuracy of our calculations are determined by the accuracy of measurements of charge deuteron form factor[17,18,19]and nucleon form factors which are the folowing at Q2≤1.717(GeV2):for G p E(Q2)1–10%[1,40,41,42],for G p M(Q2)1–3%[1,41,42,43,44], for G n M(Q2)1–10%.[4,45,46,47,48].We obtain thefirst three points at low momentum transfer from the data for the deuteron charge form factor given in the paper[18].In this range of momentum transfer the behavior of the deuteron charge form factor and so G n E(Q2)do not depend on the choose of the wave functions[28,29,30,31].Thefirst point at Q2≃0.16(GeV2)is almost the same as in[3],however,our errors are much smaller.The second and the third points are compatible(within the experimental errors)with the points of[7,8,11].Our point#7is in fact the same as in[1]but our error is larger.Our values of G n E in other points(at Q2≥1(GeV2)are strictly positive.This result differs from e.g.the results of the paper[4]consistent with G n E=0.Let us note that our errors at Q2≥1(GeV2)are sufficiently small,smaller than,e.g.in[1,4].Our values#4–8are extracted from the values of charge deuteron form factor of the two different works[17,19].The results of these works are in rather poor agreement with each other in the region of thefirst dip.So the values of#4–8of G n E are not well determined in the present work.One needs additional experiments in this region.It is now interesting tofit all the existing values of neutron charge form factor([1,3,4, 5,6,7,8,9,10,11]and Table1).We use for thefitting the following function(see[15]and the review[21])with two parameters a and b:G n E(Q2)=−µn aτ0.71−2,τ=Q2[14,39]:dG n E[9]D.Rohe et al.,Phys.Rev.Lett.83(1999)4257.[10]C.Herberg et
