Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Metal monochalcogenides have the formula ME, where M = a transition metal and E = S, Se, Te. The zinc sulfide is an inorganic compound with the chemical formula of ZnS. This is the main form of zinc found in nature, where it mainly occurs as the mineral zinc blende (sphalerite). Although this mineral is usually black because of various impurities, the pure material is white, and it is widely used as pigment. In its dense synthetic form, zinc sulphide can be transparent, and it is used as a window for visible optics and infrared optics. ZnS is a unique compound that forms two types of crystalline structures. These two polymorphs are wurtzite and zinc blende structure. wurtzite has hexagonal structure, while zinc blende is cubic. Present study is an outcome of the effort devoted to carry out a details and systematic theoretical investigation of the phonon dispersion, Debye temperatures variation, two-phonon density of states and an-harmonic elastic properties of zinc chalcogenides and applicable to all crystals of zinc-blende structure. This book is prepared based on the authors teaching the subject for master and research level in recent years. 104 pp. Englisch.…

Taschenbuch. Condición: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - The Sun is the most prominent feature in our solar system. It is the largest object and contains approximately 98% of the total solar system mass. One hundred and nine Earths would be required to fit across the Sun's disk, and its interior could hold over 1.3 million Earths. The Sun's outer visible layer is called the photo-sphere and has a temperature of 6,000°C (11,000°F). This layer has a mottled appearance due to the turbulent eruptions of energy at the surface. Solar energy is created deep within the core of the Sun. It is here that the temperature (15,000,000° C; 27,000,000° F) and pressure (340 billion times Earth's air pressure at sea level) is so intense that nuclear reactions take place. This reaction causes four protons or hydrogen nuclei to fuse together to form one alpha particle or helium nucleus. The alpha particle is about 0.7 percent less massive than the four protons. The difference in mass is expelled as energy and is carried to the surface of the Sun, through a process known as convection, where it is released as light and heat. Energy generated in the Sun's core takes a million years to reach its surface.…

Taschenbuch. Condición: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Le Soleil est l'élément le plus important de notre système solaire. Il est l'objet le plus grand et contient environ 98% de la masse totale du système solaire. Cent neuf Terres seraient nécessaires pour traverser le disque solaire, et son intérieur pourrait contenir plus de 1,3 million de Terres. La couche extérieure visible du Soleil est appelée photo-sphère et sa température est de 6 000 °C (11 000 °F). Cette couche a un aspect tacheté dû aux éruptions turbulentes d'énergie à la surface. L'énergie solaire est créée dans les profondeurs du coeur du Soleil. C'est là que la température (15 000 000° C ; 27 000 000° F) et la pression (340 milliards de fois la pression atmosphérique terrestre au niveau de la mer) sont si intenses que des réactions nucléaires ont lieu. Cette réaction fait que quatre protons ou noyaux d'hydrogène fusionnent pour former une particule alpha ou un noyau d'hélium. La particule alpha est environ 0,7 % moins massive que les quatre protons. La différence de masse est expulsée sous forme d'énergie et est transportée à la surface du Soleil, par un processus connu sous le nom de convection, où elle est libérée sous forme de lumière et de chaleur. L'énergie produite dans le noyau du Soleil met un million d'années à atteindre sa surface.…

Taschenbuch. Condición: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - O Sol é a característica mais proeminente do nosso sistema solar. É o maior objecto e contém aproximadamente 98% da massa total do sistema solar. Cento e nove Terras seriam necessárias para caber em todo o disco do Sol, e seu interior poderia conter mais de 1,3 milhões de Terras. A camada externa visível do Sol é chamada de foto-esfera e tem uma temperatura de 6.000°C (11.000°F). Esta camada tem um aspecto mosqueado devido às erupções turbulentas de energia na superfície. A energia solar é criada nas profundezas do núcleo do Sol. É aqui que a temperatura (15.000.000° C; 27.000.000° F) e a pressão (340 bilhões de vezes a pressão do ar da Terra ao nível do mar) é tão intensa que ocorrem reações nucleares. Esta reação faz com que quatro prótons ou núcleos de hidrogênio se fundam para formar uma partícula alfa ou núcleo de hélio. A partícula alfa é cerca de 0,7 por cento menos maciça que os quatro prótons. A diferença de massa é expelida como energia e é levada à superfície do Sol, através de um processo conhecido como convecção, onde é libertada como luz e calor.

È l'oggetto più grande e contiene circa il 98% della massa totale del sistema solare. Sarebbero necessarie cento nove Terre per passare attraverso il disco del Sole, e il suo interno potrebbe contenere più di 1,3 milioni di Terre. Lo strato visibile esterno del Sole è chiamato fotosfera e ha una temperatura di 6.000°C (11.000°F). Questo strato ha un aspetto screziato a causa delle turbolente eruzioni di energia in superficie. L'energia solare si crea in profondità nel nucleo del Sole. È qui che la temperatura (15.000.000.000° C; 27.000.000° F) e la pressione (340 miliardi di volte la pressione dell'aria terrestre a livello del mare) sono così intense che si verificano reazioni nucleari. Questa reazione fa sì che quattro protoni o nuclei di idrogeno si fondano insieme per formare una particella alfa o un nucleo di elio. La particella alfa è circa lo 0,7 per cento meno massiccia dei quattro protoni.
