Computer art and design of digital media technology as a typical cross-technology, combined with graphic images of modern multimedia technology, can show three-dimensional art content and animation design and production of natural affinity; therefore, the digital media technology is introduced into modern animation design and production and is an innovative design concept and method, optimizing the creation efficiency of basic requirements. The reform and innovation of animation design and production are the requirement of the development of The Times. The application of digital media technology in animation design and production is conducive to promoting the development of the animation industry. Animation is human’s pursuit of light and shadow. Based on the analysis of the characteristics of digital media, the architecture of the digital media animation system is designed, and the functions of system modules are expounded. Based on the large scale and high efficiency of digital media technology, the framework structure of the animation design system is constructed. Driven by the two-way technology and application, digital media technology is innovatively applied, and three-dimensional animation design and virtual simulation technology are integrated, so as to promote the technological upgrading of animation creation and improve its technical content and level. Through the corresponding test of the system, it is determined that the system can run normally and stably. The digital new media technology is introduced into the design and production of film and television animation to promote the digital development of animation design and production.

Wettability alteration and interfacial tension (IFT) reduction are two important mechanisms for enhanced oil recovery (EOR). The introduction of nanotechnology from the fields of Biology and Material Science to the application in EOR is emerging because nanoparticles have the potential to alter formation factors like wettability and fluid properties like IFT and viscosity. However, a systematic literature review shows that ambiguity exists regarding whether nanoparticles can change wettability and IFT or not and which component in nanofluid plays a role. In this work, we investigated the effects of bare silica nanoparticles on wettability and IFT using a contact angle goniometer. The results showed that the contact angle measurement on quartz plates had relatively large uncertainty while those on calcite plates showed a clear trend that the smaller the nanoparticle size and the larger the nanofluid concentration, the smaller the contact angle. In addition, silica nanoparticles did not have an effect on IFT. Core flooding experiments showed an increase of 8.7% in oil recovery factor by the use of silica nanoparticles, which support the oil recovery mechanism of wettability alteration.

Developing an advanced heterogeneous catalyst is essential for realizing high‐performance ammonia borane (AB) hydrolysis, which is a safe and efficient way to generate hydrogen. In this work, a series of ruthenium (Ru) nanoparticles (NPs) immobilized on chitosan (CS) natural polymers are synthesized via an adsorption‐in situ reduction method. Various analytical techniques, including XRD, XPS, FT‐IR, SEM and TEM, are adopted to explore the structure‐catalytic performance relationships of the obtained catalysts for hydrolysis of AB. Benefitting from the possible interaction between Ru NPs and the amino and hydroxyl groups in CS, the as‐prepared catalysts exhibit excellent catalytic behavior for hydrogen generation from AB hydrolysis. Catalyzed by the optimal Ru/CS, the turnover frequency reaches up to 331.8 min−1 in NaOH solution at 303 K, and the corresponding apparent activation energy is 41.3 kJ mol−1, which are superior to many results previously reported. This work demonstrates that the obtained Ru/CS is a promising and efficient catalyst for the hydrolysis of solid hydrogen storage materials.
