Gold black and gold cermet absorbing surfaces

Infrared light-absorbing gold/gold sulfide nanoparticles induce cell death in esophageal adenocarcinoma

Gold nanoparticles and near infrared-absorbing light are each innocuous to tissue but when combined can destroy malignant tissue while leaving healthy tissue unharmed. This study investigated the feasibility of photothermal ablation therapy for esophageal adenocarcinoma using chitosan-coated gold/gold sulfide (CS-GGS) nanoparticles. A rat esophagoduodenal anastomosis model was used for the in v...

OLD GOLD AND BLACK Nobel Prize .

Each school of the univru:sity picked representatives for a 10 member faculty advisory committee to the trustee search ·committee. This method of forming the faculty advisory committee is more democratic than simply placing the senate faculty members on the committee, Percival Perry, dean of the summer session .and professor of history, Perry said. replaced associate professor of biology Ron Di...

Nanoscale thermal radiation between two gold surfaces

Superlubricity of graphene nanoribbons on gold surfaces.

The state of vanishing friction known as superlubricity has important applications for energy saving and increasing the lifetime of devices. Superlubricity, as detected with atomic force microscopy, appears when sliding large graphite flakes or gold nanoclusters across surfaces, for example. However, the origin of the behavior is poorly understood because of the lack of a controllable nanoconta...

Wetting of regularly structured gold surfaces.

In this study we report results for a systematic study of the wetting of structured gold surfaces formed by electrodeposition through monolayer templates of close-packed uniform submicrometer spheres. Removal of the template after deposition leaves a regular hexagonal array of sphere segment pores where the depth of the pores and, thus, the topography of the surface are controlled by the thickn...
