Microwave-Assisted Au and Ag Nanoparticle Synthesis: An Energy Phase-Space Projection Analysis

Microwave-assisted synthesis of gold and silver nanoparticles, as a function of Green Chemistry, non Green Chemistry, and four applicator types are reported. The applicator types are Domestic microwave ovens, commercial temperature controlled microwave chemistry ovens (TCMC), digesters, and axial field helical antennae. For each of these microwave applicators the process energy budget where estimated (Watts multiplied by process time = kJ) and energy density (applied energy divided by suspension volume = kJ·ml-1) range between 180 ± 176.8 kJ, and 79.5 ± 79 kJ·ml-1, respectively. The axial field helical field an-tenna applicator is found to be the most energy efficient (0.253 kJ·m-1 per kJ, at 36 W). Followed by microwave ovens (4.47 ± 3.9 kJ·ml-1 per 76.83 ± 39 kJ), and TCMC ovens (2.86 ± 2.3 kJ·m-1 per 343 ± 321.5 kJ). The digester applicators have the least energy efficiency (36.2 ± 50.7 kJ·m-1 per 1010 ± 620 kJ). A comparison with reconstructed ‘non-thermal’ microwave oven inactivation microorganism experiments yields a power-law signature of n = 0.846 (R2 = 0.7923) four orders of magnitude. The paper provides a discussion on the Au and Ag nanoparticle chemistry and bio-chemistry synthesis aspects of the microwave applicator energy datasets and variation within each dataset. The visual and analytical approach within the energy phase-space projection enables a nanoparticle synthesis route to be systematically characterized, and where changes to the synthesis are to be mapped and compared directly with historical datasets. In order to help identify lower cost nanoparticle synthesis, in addition to potentially reduce synthesis energy to routes informed changes to potentially reduce synthesis energy budget, along with nanoparticle morphology and yield.

Self-adaptive one-dimensional nonlinear finite element method based on element energy projection method

The element energy projection （EEP） method for computation of super- convergent resulting in a one-dimensional finite element method （FEM） is successfully used to self-adaptive FEM analysis of various linear problems, based on which this paper presents a substantial extension of the whole set of technology to nonlinear problems. The main idea behind the technology transfer from linear analysis to nonlinear analysis is to use Newton＇s method to linearize nonlinear problems into a series of linear problems so that the EEP formulation and the corresponding adaptive strategy can be directly used without the need for specific super-convergence formulation for nonlinear FEM. As a re- sult, a unified and general self-adaptive algorithm for nonlinear FEM analysis is formed. The proposed algorithm is found to be able to produce satisfactory finite element results with accuracy satisfying the user-preset error tolerances by maximum norm anywhere on the mesh. Taking the nonlinear ordinary differential equation （ODE） of second-order as the model problem, this paper describes the related fundamental idea, the imple- mentation strategy, and the computational algorithm. Representative numerical exam- ples are given to show the efficiency, stability, versatility, and reliability of the proposed approach.

SELF-ADAPTIVE STRATEGY FOR ONE-DIMENSIONAL FINITE ELEMENT METHOD BASED ON ELEMENT ENERGY PROJECTION METHOD

Based on the newly-developed element energy projection （EEP） method for computation of super-convergent results in one-dimensional finite element method （FEM）, the task of self-adaptive FEM analysis was converted into the task of adaptive piecewise polynomial interpolation. As a result, a satisfactory FEM mesh can be obtained, and further FEM analysis on this mesh would immediately produce an FEM solution which usually satisfies the user specified error tolerance. Even though the error tolerance was not completely satisfied, one or two steps of further local refinements would be sufficient. This strategy was found to be very simple, rapid, cheap and efficient. Taking the elliptical ordinary differential equation of second order as the model problem, the fundamental idea, implementation strategy and detailed algorithm are described. Representative numerical examples are given to show the effectiveness and reliability of the proposed approach.

Fast forward modeling of muon transmission tomography based on model voxelization ray energy loss projection

To solve the problems associated with low resolution and high computational effort infinite time,this paper proposes a fast forward modeling method for muon energy loss transmission tomography based on a model voxelization energy loss projection algorithm.First,the energy loss equation for muon transmission tomography is derived from the Bethe–Bloch formula,and the imaging region is then dissected into several units using the model voxelization method.Thereafter,the three-dimensional(3-D)imaging model is discretized into parallel and equally spaced two-dimensional(2-D)slices using the model layering method to realize a dimensional reduction of the 3-D volume data and accelerate the forward calculation speed.Subsequently,the muon energy loss transmission tomography equation is discretized using the ray energy loss projection method to establish a set of energy loss equations for the muon penetration voxel model.Finally,the muon energy loss values at the outgoing point are obtained by solving the projection coefficient matrix of the ray length-weighted model,achieving a significant reduction in the number of muons and improving the computational efficiency.A comparison of our results with the simulation results based on the Monte Carlo method verifies the accuracy and effectiveness of the algorithm proposed in this paper.The metallic mineral identification tests show that the proposed algorithm can quickly identify high-density metallic minerals.The muon energy loss response can accurately identify the boundary of the anomalies and their spatial distribution characteristics.

Ethical Perspective on Turkish Environmental Impact Assessment for Nuclear Energy

In 2013, The Turkish Ministry of Environment and Urban Planning issued four thousand pages of a cut and paste Environmental Impact Assessment （EIA） report for the Akkuyu nuclear power plant and nuclear fuel fabrication complex project located on Turkey＇s Mediterranean coastline, in the Mersin providence, which will be built on a build-own-operate basis by Russian company Rosatom. Numerous complaints have already been filed against the EIA, challenging the scientific integrity of the report on the following grounds： misrepresentation of failure to specify the radioactive inventory and of projected releases into the environment, omitting tritium and carbon-14; incomplete information about the toxic chemicals which will be injected into the cooling system throughout the nuclear complex; misleading information about the cooling water＇s temporal and chemical effects on marine life; lack of details on an emergency evacuation plan; lack of a comprehensive nuclear waste management plan; unspecified insurance coverage for the nuclear complex, noncompliance with third party liability requirements. Coupled with these complaints are allegations that signatures on some sensitive reports contained or referred to have been falsified.

Self-adaptive strategy for one-dimensional finite element method based on EEP method with optimal super-convergence order

Based on the newly-developed element energy projection （EEP） method with optimal super-convergence order for computation of super-convergent results, an improved self-adaptive strategy for one-dimensional finite element method （FEM） is proposed. In the strategy, a posteriori errors are estimated by comparing FEM solutions to EEP super-convergent solutions with optimal order of super-convergence, meshes are refined by using the error-averaging method. Quasi-FEM solutions are used to replace the true FEM solutions in the adaptive process. This strategy has been found to be simple, clear, efficient and reliable. For most problems, only one adaptive step is needed to produce the required FEM solutions which pointwise satisfy the user specified error tolerances in the max-norm. Taking the elliptical ordinary differential equation of the second order as the model problem, this paper describes the fundamental idea, implementation strategy and computational algorithm and representative numerical examples are given to show the effectiveness and reliability of the proposed approach.

Emission reduction effects of the green energy investment projects of China in belt and road initiative countries

Investment and construction of power infrastructure are directly related to the achievement of sustainable development goals.China's trade and investment with BRI(Belt and Road Initiative)countries have maintained growth trend.The development and construction of these investment projects certainly have impacts on the economic development mode and sustainable development goals of the countries.On collecting the basic information of the renewable energy investment projects,this paper compares and calculates the current power technology structure and grid emission factors of the host countries,and analyses the carbon emission level of electricity generation from the perspective of the whole life cycle.Making it as the benchmark,this paper also analyzes the current China's invested wind and solar energy projects and the carbon emission reduction benefits to the host country.The results show that at present,China has about 36 renewable energy investment projects in BRI countries,with an installed capacity of 15.75GW(China as the project owner or investor),and achieve at least 48.69M tCO2 emission reduction.This shows that China's effective investment and implementation of the green projects will provide a strong impetus for the energy transformation and the improvement of their energy security in BRI countries.

COMPUTATION OF SUPER-CONVERGENT NODAL STRESSES OF TIMOSHENKO BEAM ELEMENTS BY EEP METHOD

The newly proposed element energy projection(EEP) method has been applied to the computation of super_convergent nodal stresses of Timoshenko beam elements.General formulas based on element projection theorem were derived and illustrative numerical examples using two typical elements were given.Both the analysis and examples show that EEP method also works very well for the problems with vector function solutions.The EEP method gives super_convergent nodal stresses,which are well comparable to the nodal displacements in terms of both convergence rate and error magnitude.And in addition,it can overcome the “shear locking” difficulty for stresses even when the displacements are badly affected.This research paves the way for application of the EEP method to general one_dimensional systems of ordinary differential equations.

Criterion of aerodynamic performance of large-scale offshore horizontal axis wind turbines

With the background of offshore wind energy projects, this paper studies aerodynamic performance and geometric characteristics of large capacity wind turbine rotors （1 to 10 MW）, and the main characteristic parameters such as the rated wind speed, blade tip speed, and rotor solidity. We show that the essential criterion of a high- performance wind turbine is a highest possible annual usable energy pattern factor and a smallest possible dimension, capturing the maximum wind energy and producing the maximum annual power. The influence of the above-mentioned three parameters on the pattern factor and rotor geometry of wind turbine operated in China＇s offshore meteoro- logical environment is investigated. The variation patterns of aerodynamic and geometric parameters are obtained, analyzed, and compared with each other. The present method for aerodynamic analysis and its results can form a basis for evaluating aerodynamic performance of large-scale offshore wind turbine rotors.

The Environmental Democracy under Political Siege in Turkey

On June 24th, 2018, President Tayyip Erdogan, along with his pro-Islamic party, the Justice and Development Pazty, AKP, won the general election in Turkey, which will enable Mr. Erdogan to be a one-man ruler of the Republic of Turkey in the foreseeable future. Now, invested with infinite executive-presidential power, coupled with having complete control of the military, cabinet, judiciary and legislative branches, enables Mr. Erdogan to pursue his ambition to be a “nuclea3： power leader” in the Sunni Islamic world. The scientific denialism in general and environmental science, in particular, will reach a whole new level of insanity in Turkey where any conceivable environmental democracy will be abolished. The new government will further change the education establishment in every level and implement its anti-science political doctrines in which logic is an enemy and scientific truth is a menace. The last fifteen years of experience show that the AKP＇s politicians have become anti-science zealots who preach a dangerously new political cultism that is devoid of actual facts, if it does not fit their religious aberration narrative, Thus, virtually every aspect of the nuclear power program in Turkey will be a state secret under the control of one religiously motivated and driven ruler and this, should certainly sound alarm bells across the globe.

Real option-based optimization for financial incentive allocation in infrastructure projects under publicprivate partnerships

Financial incentives that stimulate energy investments under public-private partnerships are considered scarce public resources,which require deliberate allocation to the most economically justified projects to maximize the social benefits.This study aims to solve the financial incentive allocation problem through a real option-based nonlinear integer programming approach.Real option theory is leveraged to determine the optimal timing and the corresponding option value of providing financial incentives.The ambiguity in the evolution of social benefits,the decision-maker’s attitude toward ambiguity,and the uncertainty in social benefits and incentive costs are all considered.Incentives are offered to the project portfolio that generates the maximum total option value.The project portfolio selection is formulated as a stochastic knapsack problem with random option values in the objective flinction and random incentive costs in the probabilistic budget constraint.The linear probabilistic budget constraint is subsequently transformed into a nonlinear deterministic one.Finally,the integer non-linear programming problem is solved,and the optimality gap is computed to assess the quality of the optimal solution.A case study is presented to illustrate how the limited financial incentives can be optimally allocated under uncertainty and ambiguity,which demonstrates the efficacy of the proposed method.
