The influence of discharge rate, ambient temperature, and phase change material on the maximum temperature highest difference was investigated. battery tested with without under extreme rates (4C 5C) temperatures (310 K 320 K). Results showed that a reduced from 327.94 to 306.45 for 14.6 Ah lithium-ion discharged at 5C-rate K. Quantitatively determined parameter effects revealed PCM considerabl...

We have studied initial growth of Sn atoms on Ge(001) surfaces at room temperature and 80 K by scanning tunneling microscopy. For Sn deposition onto the Ge(001) substrate at room temperature, the Sn atoms form two kinds of one-dimensional structures composed of ad-dimers with different alignment, in the 〈310〉 and the 〈110〉 directions, and epitaxial structures. For Sn deposition onto the substra...

The Na 2 SO 4 samples were obtained by slow evaporation method. mechanisms of the formation electron and hole trapping centers are investigated spectroscopic methods. Intrinsic recombination emission 2.9–3.1 eV impurity 1.85 excited at 4.0–4.5 eV. 3− −SO − Mn + revealed. local levels corresponding between center decay intrinsic was recorded temperatures 130–150 K 280–350 K.

solution potassium (so-k) and exchangeable k (ex-k) extracted by nh4oac are the major sources of potassium used by plants, but initially non-exchangeable k (nex-k) can also contribute significantly to plant uptake. perennial ryegrass (lolium perenne, cv. roper) was successively planted in ten surface soil samples with different clay mineralogical composition belonging to five soil types to dete...

For a large class of unitarily invariant reproducing kernel functions K on the unit ball \(\mathbb B_d\) in C^d\), we characterize K-inner as admitting suitable transfer function realization. We associate with each K-contraction T ∈ L(H)d canonical operator-valued and extend uniqueness theorem Arveson for minimal K-dilations to our setting. thus generalize results Olofsson m-hypercontractions d...

The relaxation behavior of poly(2,3-dichlorobenzyl methacrylate) is studied by broadband dielectric spectroscopy in the frequency range of 10(-1)-10(9) Hz and temperature interval of 303-423 K. The isotherms representing the dielectric loss of the glassy polymer in the frequency domain present a single absorption, called beta process. At temperatures close to Tg, the dynamical alpha relaxation ...
