Molecular dynamics of argon atoms in a nano-triangular channel which consists of (111) platinum walls were studied. The molecular dynamics simulations aim to gain understanding in the heat transfer through the channel including the influence of the contact resistances which become important in small-scale systems. The heat transfer properties of the finite-space system were measured at a quasi-...

Cisplatin (cis-(diammine)dichloridoplatinum(II)) is the first platinum-based compound approved by United States Food and Drug Administration (FDA) (U.S.). This a first-line chemotherapeutic treatment used alone or combined with other anticancer drugs to treat broad spectrum of malignancies, cisplatin-based nano-formulations currently in clinical studies. has several drawbacks, including low aqu...

Abstract Understanding and controlling the swimming direction of a synthetic nano‐ micromotor holds fundamental applied significance. Here, we focus on platinum‐containing Janus colloids that catalytically decompose H 2 O into , an archetypical model chemical micromotor. We discover platinum oxides (primarily PtO) are produced Pt films sputter‐coated in plasma, PtO reverses motor possibly by se...

Crystal phase regulations may endow materials with enhanced or new functionalities. However, syntheses of noble metal-based allomorphic nanomaterials are extremely difficult, and only a few successful examples have been found. Herein, we report the discovery of hexagonal close-packed Pt-Ni alloy, despite the fact that Pt-Ni alloys are typically crystallized in face-centred cubic structures. The...

Nano- and microscale motors powered by catalytic reactions exhibit collective behavior such as swarming, predator-prey interactions, and chemotaxis that resemble those of biological microorganisms. A quantitative understanding of the catalytically generated forces between particles that lead to these behaviors has so far been lacking. Observations and numerical simulations of pairwise interacti...

Introducing a hydrophobic property to vertically aligned hydrophilic metallic nanorods was investigated experimentally and theoretically. First, platinum nanorod arrays were deposited on flat silicon substrates using a sputter Glancing Angle Deposition Technique (GLAD). Then a thin layer of Teflon (nanopatches) was partially deposited on the tips of platinum nanorod at a glancing angle of θ = 8...

A Si/SiO(2)/CuPt structure is formed by depositing a very thin SiO(2) layer between CuPt and P-type Si layers using e-beam evaporation. SEM images show the formation of CuPt nano clusters with an average size of less than 100 nm. This structure shows high sensitivity to applied magnetic fields at 77K and at low and high dc voltages such that magnetic field as low as 6 mT is detected using I-V a...
