Structure and stability of core-shell Cu-Pt nanoparticles for catalytic applications
, 2023 We have successfully synthesized monodisperse core-shell Cu-Pt particles through a solvothermal method that enables control of the shell thickness to enhance the exposed Pt surface area and keep a narrow size distribution.

Topology optimization of core structure of titanium alloy sandwich cylindrical shell
Zhongguo Jianchuan Yanjiu, 2023 Objectives As a new type of pressure-resistant structure, the titanium alloy sandwich cylindrical shell has not yet been studied comprehensively. The topology of the core layer needs to be confirmed using the optimization method.

Photon management with core-shell nanowire structures
Optics Express, 2012 Antireflective Si/oxide core-shell nanowire arrays (NWAs) were fabricated by galvanic etching and subsequent annealing process. The excellent light-harvesting characteristics of the core-shell NWAs, such as broadband working ranges, omnidirectionality, and polarization-insensitivity, ascribed to the smooth index transition from air to the substrates ...

Two-dimensional C/BN core/shell structures [PDF]
Physical Review B, 2011 Single layer core/shell structures consisting of graphene as core and hexagonal boron nitride as shell are studied using first-principles plane wave method within density functional theory. Electronic energy level structure is analysed as a function of the size of both core and shell.

Soft Deployable Structures via Core-Shell Inflatables
Physical Review Letters, 2023 Deployable structures capable of significant geometric reconfigurations are ubiquitous in nature. While engineering contraptions typically comprise articulated rigid elements, soft structures that experience material growth for deployment mostly remain the handiwork of biology, e.g., when winged insects deploy their wings during metamorphosis.

Tuning the Interfacial Stoichiometry of InP Core and InP/ZnSe Core/Shell Quantum Dots
, 2021 We demonstrate fine-tuning of the atomic composition of InP/ZnSe QDs at the core/shell interface. Specifically, we control the stoichiometry of both anions (P, As, S, and Se) and cations (In, Zn) at the InP/ZnSe core/shell interface and correlate these ...
