Tässä työssä tutkitaan suotoveden käsittelyä käyttämällä sitä kierrätysmateriaaleista valmistetussa tuhkamullassa loppusijoitusalueen päällä kasvatettavan energiapuukasvuston kasteluun. Kyseisen toimintamallin tarkoituksena on haihduttaa suotovettä energiapuiden avulla sekä sitouttaa ravinteita ja haitta-aineita sekä…
Significance and Use 5.1 Uranium and plutonium are used in nuclear reactor fuel and must be analyzed to insure that they meet certain criteria for isotopic composition as described in Specification C833 and Specification C1008. This standard practice is u
以三乙醇胺为催化剂,十六烷基三甲基溴化铵（CTAB）为模板剂,通过硅烷四乙酯（TEOS）和3-巯丙基三乙氧基硅烷（MPTES）共水解,成功制备了巯基功能化介孔二氧化硅纳米微球.用盐酸—乙醇混合溶液去除模板后,这种介孔纳米微球能有效吸附银离子,进一步反应得到SiO2-Ag和SiO2-Ag2S复合纳米微球.用X射线衍射、透射电子显微镜、热分析以及紫外—可见光谱表征了微球形貌、结构与性能.这种复合纳米微球平均粒径约70nm,Ag2S微粒小于10 nm且担载于SiO2微球表面,而Ag量子点则包覆于介孔硅的内部,在350 nm到700 nm范围呈现明显的宽吸收.另外,这两种复合纳米微球作为无机抗菌剂都表现出良好的抗菌性能.
Picosecond time-resolved in situ X-ray absorption and X-ray photoelectron spectroscopy techniques for atomic site-specific real-time studies of interfacial photoelectrochemistry are developed. First experiments monitor electronic dynamics of dye-sensitized nanocrystals and at hematite-electrolyte interfaces.
For the purpose of ultra-thin layer MLCC application, a commercial BaTiO3 dielectric powder with an average particle size of 80 nm was used to apply additives, such as Dy, Mg, Mn, Si, Ba and Ca, by a coating method and the microstructure and dielectric properties of BaTiO3 sintered materials were investigated, as a fu…
This thesis presents a comprehensive investigation of unsteady friction modeling. The research falls into two areas: assess the necessity of unsteady friction modeling and improve on existing models. The importance of unsteady friction in two pipe systems connected in series is determined. A new index (re) measuring t…
A poly(erythrosine) chemical modified electrode (P-Ery/GCE/CME) was fabricated by electrochemical immobilization of erythrosine on a glassy carbon electrode through cyclic voltammetry. The modified electrode had good electrocatalytic oxidization function to catechol and it significantly increased the catechol oxidatio…
A particle can be trapped inside such a mirror field (electric and magnetic field) and its velocity, acceleration and all other type of kinematic movement can be controlled.
Terahertz-wave generation in organic ferroelectrics α-(ET)2I3 is over 70 times more efficient than prototypical ZnTe. Ultrafast (< 0.1 ps) and sensitive (~ 40 %) photoresponse of the terahertz wave results from strongly-correlated electrons therein.
Quantum properties of a monolayer graphene are studied in terms of the Clifford algebras. The simplest of algebras suitable for this purpose appears to be Cl3,0 algebra, the basis vectors of which represent 3D rather than 2D Euclidean space. If electron spin is included, higher dimensional algebras should be used. It…
Materials systems that undergo magnetostructural phase transitions (simultaneous magnetic and structural phase changes) have the capability of providing exceptional functional effects (example: colossal magnetoresistance effect (CMR), giant magnetocaloric (GMCE) and giant volume magnetostriction effects) in response t…
Thermoelectric Conversion Materials" have recently attracted the attention of many researchers, and also have been investigated very actively.The Thermoelectrics Society of Japan was established on April 1st, 2004.Since the predecessor group of the society started in 1994, research activity on thermoelectrics in Japan…
Protein encapsulated gold nanocluster (P-AuNC) synthesis was first demonstrated in 2009.[1]Initially these P-AuNCs were used as cellular imaging agents as the protein shell surrounding the AuNC made them highly biocompatible.However, recent studies have begun to show that these stabilizing proteins may also retain nat…
We explore ultrafast structural transformation in the Ge2Te2/Sb2Te3 superlattice, using pump-pump-probe spectroscopy. The coherent phonon spectra exhibit complex structural dynamics upon photo-excitation, being described as the mixing of two different Ge bonding configurations.
This year Smithers Rapra Technology Ltd is running a short course entitled ‘Introduction to Rubber Technology’ at its premises in Shawbury, Shropshire, UK, on 11–12 March. It will be repeated on 23–24 September.
Osteoconductive biomaterials such as calcium phosphate bioceramics have been widely used as scaffolds for bone tissue engineering. However, this kind of materials usually lacks osteoinductivity and is not able to stimulate osteogenic differentiation of stem cells. In addition, angiogenesis plays an important role in t…
