Whats New

New Equipment

A new Scanning Electron Microscope (SEM), equipped with Oxford EDX System, is now located at Concrete Materials Laboratory (ZB109). This tungsten thermionic emission SEM system is suitable for low- and high-vacuum operations. A high spatial resolution with secondary electron (SE) and backscatter (BSE) detector allows the observation with fine surface details, whilst the EDX detector provides elemental and chemical analysis. The SEM is designed for comprehensive materials characterization down to nanoscale. This instrument is best suited to imaging and analysis of coated samples that are stable under the electron beam, e.g. concrete, rocks, metals and alloys.

Specifications / Applications:

• An extra-large analytical chamber with a full 5-axis motorized stage
• Detector: SE, BSE, EDX
• Imaging up to 100,000X
• Accelerating voltage: 200V to 30 kV
• 5 Electron Optics Working Modes: Resolution, Depth, Field, Wide Field, Channeling
• Rotation: 360°continuous / Tilt: -30° to +90°
• IR TV Camera for the “Chamber View”

Establishment of CEE-RSAA

Alumni network is the invaluable asset of our Department. CEE-RSAA has been established with an aim to reconnect all its research alumni and scholars, who were encouraged to work together for the benefit of the association and the wider community. Below is their logo and its meaning (in Chinese version only).

• Logo在CEE現有的logo基礎上形成； • Logo整體造型為房屋形式，屋頂為變型的字母C，兩側巨大的支柱為字母E， • 中間牆體為校友會的英文縮寫RSAA，與支柱一起支撐起屋頂； • Logo整體造型寓意校友們一直受益於CEE的呵護支持，分佈於各地，共同構建一個溫暖的集體和溫馨的心靈家園； • Logo顏色取PolyU的紅磚代表色。

The 28th CEESS

The 28th CEESS Executive Committee (Ex-Co) of the Hong Kong Polytechnic University Students' Union, Orenda, is set
up. You may learn more about the meaning of their name, Ex-Co members and news from their Instagram: hkpusu_28ceess.
