Opis:
Carrier recombination dynamics in polar and nonpolar GaN epilayers and GaN/AlGaN multiple quantum wells grown over sapphire substrates with various crystallographic orientation were studied under high photoexcitation by 20 ps laser pulses. The transient of luminescence featured a significant enhancement in nonradiative recombination of free carriers for nonpolar a-plane GaN epilayers compared to conventional c-plane samples. The epitaxial lateral overgrowth technique was demonstrated to significantly improve the quality of nonpolar a-plane films. This was proved by more than 40-fold increase in luminescence decay time (430 ps compared to ≤10 ps in the ordinary a-plane epilayer). Under high-excitation regime, a complete screening of built-in electric field by free carriers in multiple quantum wells grown on c-plane and r-plane sapphire substrates was achieved. Under such high excitation, luminescence efficiency and carrier lifetime of multiple quantum wells was shown to be determined by the substrate quality.

Opis:
GaN epilayers and AlGaN/GaN multiple quantum wells grown by metalorganic chemical vapor deposition on different crystal planes (c, a, and r) of the sapphire substrate were studied by excitation intensity dependent and time-resolved photoluminescence. In polar multiple quantum wells grown on a- and c-planes, a blueshift of the luminescence band with increasing the excitation energy was observed, indicating that screening of built-in field by free carriers takes place, whereas in nonpolar r-plane grown multiple quantum wells, the luminescence band maintained an almost constant peak position. Full screening of built-in field was achieved at the excitation densities higher than 0.3 mJ/cm$\text{}^{2}$. Under conditions of screened built-in electric field the structures were characterized by carrier lifetime. It was shown that nonpolar multiple quantum wells suffer from high density of nonradiative traps that can be due to substrate related threading dislocations.

Opis:
Węgiel kamienny jest bardzo trudno wzbogacalny w procesie konwencjonalnej flotacji z zastosowaniem odczynników (kolektorów) olejowych. Badania miały na celu zaprojektowanie procesu flotacji, nazywanej flotacją olejową, do zwiększenia efektywności wzbogacania utlenionego węgla. Opisano proces flotacji olejowej. Badania dotyczyły porównania flotacji olejowej i konwencjonalnej do wzbogacania utlenionego węgla. Niektóre właściwości utlenionego węgla są podobne do właściwości węgla brunatnego. Odczynniki flotacyjne (kolektory) mają wielki wpływ na proces utlenionego węgla. Flotowalność utlenionego węgla z Taixi (Chiny) może być poprawiona przez aktywację powierzchni bądź rozdrabnianie węgla. Wstępna obróbka mikrofalowa może zwiększyć hydrofobowość węgla utlenionego poprzez zmniejszenie zawartości wilgoci w węglu utlenionym. Wyniki pokazują, że flotacja z pęcherzykami oleistymi jest bardziej efektywna, gdyż uzyskuje się substancję organiczną (koncentraty węgla) o wyższej zawartości substancji palnych niż w konwencjonalnym procesie flotacji. Wskaźnik efektywności procesu przy zastosowaniu flotacji olejowej jest również wyższy niż przy zastosowaniu konwencjonalnej flotacji.
Oxidized coal is difficult to float using oily collectors in the conventional flotation process. This study was aimed at designing the flotation process, namely the oily bubble flotation process, to float oxidized coal efficiently. The flotation process using oily bubbles is thoroughly described. The study compared using oily bubbles and air bubbles to float oxidized coal. Some properties of oxidized coal are similar to lignite. Therefore, oxidized coal should also be recovered efficiently. The flotation collectors have a great effect on the flotation process of oxidized coal. The floatability of Taixi oxidized coal can be improved by surface activation or grinding. The microwave pretreatment can improve the hydrophobicity of oxidized coal by decreasing the moisture content of oxidized coal. The flotation results show that the oily bubble flotation process can obtain higher combustible matter recovery than the conventional flotation process. The flotation efficiency index using oily bubbles is also higher than that using air bubbles.

Opis:
Due to the great danger of the collision of oil tankers, lots of research on the collision of oil tankers has been carried out. But, at present, the research on the collision of oil tankers mainly focuses on the loading condition of the struck ship, ignores the impact on the loading condition of the striking ship. However, during the actual oil tanker collision, the striking ship is generally in the state of loading. Therefore, it is necessary to carry out the analysis of the impact of the loading condition of the striking ship on the collision damage of the oil tanker. In this paper, the effect of striking ship with loading on the impact performance of the side structure during the collision of the cargo double hull oil tanker has been investigated. The ship collision model was established by using the finite element software ANSYS/ LS-DYNA which is based on 7000 tons of double hull oil tankers. Based on the analysis of the collision force, impact of striking speed changes, impact of striking deep changes and structural energy absorption during the collision process, the influence of the striking ship with loading on the damage mechanism and the impact performance of the double shell oil ship side structure was expounded. The results show that the influence of the striking ship with loading can be great to the damage to side hull during the research of the collision performance of the oil tanker.

Opis:
In order to identify high-speed navigation ability of trimaran planing hull, as well as investigate the characteristics of its resistance and hull form, ship model tests were conducted to measure resistance, trim and heaving under different displacements and gravity centre locations. The test results were then used to study the influence of spray strips on resistance and sea-keeping qualities. Moreover, different planning surfaces were compared in the model tests which helped to look into influence of steps on hull resistance and its moving position. Also, the resistance features of monohull and trimaran planing hulls, both with and without steps, were compared to each other. From the tests it can be concluded that: the two auxiliary side hulls increase aerodynamic lift at high-speed motion, which improves the hydrodynamic performance; the trimaran planing hull has also excellent longitudinal stability and low wave-making action; when Fr∇> 8, its motion is still stable and two distinct resistance peaks and two changes of sailing state (the second change is smaller) appear; spray strips are favourable for sea-keeping qualities at high speed. The change trends before the second resistance peak as to the resistance and sailing behaviour of trimaran planing hull without steps are the same as for monohull planing hull without steps. but when steps in both hulls exist the change trends are different; more specifically: trimaran planing hull with steps has only one resistance peak and its resistance increases along with its speed increasing, and the resistance is improved at the increasing speed as the number of steps increases.

Opis:
The analytic mean field potential approach is applied to α-, β-, and γ-Si₃N₄. The analytic expressions for the Helmholtz free energy, internal energy, and equation of state were derived. The formalism for the case of the Morse potential is used in this work. Its six potential parameters are determined through fitting the compression experimental data of α-, β-, and γ-Si₃N₄. The calculated compression curves of α-, β-, and γ-Si₃N₄ are in good agreement with the available experimental data. This suggests that the analytic mean field potential approach is a very useful approach to study the thermodynamic properties of Si₃N₄. Furthermore, we predict the variation of the free energy and internal energy with the molar volume at several higher temperatures and calculate the temperature dependence of the molar volume, bulk modulus, thermal expansion coefficient and isochoric heat capacity at zero pressure.

Opis:
Orchard development on eroded uplands is considered as a successful method in integrating soil erosion treatment with economic development in many developing countries. However, much attention focused on its present achievements without thinking over the economic viability over long plantation duration. Orchards that have not been intensified seem to be threatened by complete abandonment. To illustrate the economic viability and sustain-ability of orchard management, we have deliberately focused on a case study in Southeast China. The results of economic viability based on a cost-benefit analysis showed that orchard management was barely economically sustainable. Their viability is assured if reduced labor costs and increased fruit price are accepted. Based on these results, recommendations are made to prevent the abandonment of orchards on degraded uplands and to preserve its environmental benefits.
Tworzenie sadów na zerodowanych wyżynach w wielu krajach rozwijających się jest traktowane jako metoda udanie łączącą zintegrowane przeciwdziałanie erozji gleb z rozwojem ekonomicznym. Niestety, zbyt mocno podkreśla się znacznie szybkich osiągnięć, bez rozważania kontekstu wieloletniej opłacalności takich działań. Sady, których nie poddano modyfikacjom, opuszczono. By zilustrować ekonomiczną sensowność i zrównoważoność zarządzania sadami, wybrano jako case study obszar płd.-wsch. Chin. Rezultaty oceny opartej na analizie kosztów i korzyści wykazały, że zarządzanie sadami okazuje się być słabo ekonomicznie zrównoważone. Opłacalność zostałaby zapewniona w przypadku obniżenia kosztów pracy i podniesienia cen owoców. Na podstawie przeprowadzonych badań przedstawiono rekomendacje, których uwzględnienie umożliwiłoby zaprzestanie procederu rezygnacji z prowadzenia sadów na terenach zdegradowanych wyżyn i utrzymanie korzyści środowiskowych.

Opis:
U-type ferrite typified by Ba4Co2Fe36O60 is used as a RAM (Radar Absorbing Materials) in the X-band (8-12 GHz). Ba4Co2Fe36O60 is known to have a complex crystal structure, which makes it difficult to obtain single phase and have low reproducibility. Previously known U-type ferrites have been fabricated based on a ceramic process that mixing (by a ball mill), calcining, grinding, binder mixing, drying, sieving, pressing and sintering. In contrast, the process of preparing the powder by the sol-gel method and its heat-treating is advantageous in that it can reduce the process steps and the required time. In addition, the precise stoichiometric control by the sol-gel method can effectively evaluate the effect of added or substituted elements. In this study investigates the crystal structure of Ba4Co2Fe36O60 synthesized by the sol-gel method and the morphology of U-type ferrite nano-powders according to various heat treatment conditions. Analysis of the crystal structure is used for XRD. Morphology and size are observed by SEM. In addition, VSM is performed to confirm the change of magnetic properties according to various heat treatment conditions.

Oxetane-based polymers substituted with difluoroamino groups can be used as energetic binders in propellants and polymer-bonded explosives (PBXs). As a novel candidate, poly(3-difluoroaminomethyl-3-methyloxetane/3-nitratomethyl-3-methyloxetane) (PDN) was synthesized and its structure was established. Thermogravimetry (TG) and differential scanning calorimetry (DSC) were employed to investigate its thermal decomposition behaviour. The compatibility between PDN and some common ingredients of propellants and PBXs was evaluated by the DSC method. PDN with good thermal stability was synthesized via a cationic solution polymerization process. Additionally, it has improved compatibility with cyclotetramethylenetetranitramine (HMX), carbon black (C.B.) and lead carbonate (PbCO3) compared with homopoly(3-difluoroaminomethyl-3-methyloxetane) (PDFAMO). PDN could be used as a promising difluoroamino energetic binder in the future.

Opis:
Energetic salts as a unique class of energetic materials have recently been investigated widely, since they possess advantages over their atomically similar nonionic analogues – they tend to exhibit lower vapor pressures, higher densities and better thermal stabilities. Furthermore, these salts are readily improved upon by the appropriate combination of different cations and anions. Over the last twenty years, our group has continued to synthesize and study novel ionic energetic materials. Here, we have summarized all of the series of nitrogen-rich energetic salts. This review gives an overview of the various studies dealing with synthetic aspects and some of the physicochemical properties of ionic compounds that are based on ammonia, guanidine, semicarbazide, carbohydrazide, tetrazine, tetrazole, triazole and imidazole. In addition, their potential applications in the fields of explosives and propellants are discussed. We hope these investigations will be helpful in providing a wider insight for future research in the area of energetic salts.
