Meng-Yu Weng Award Candidate Real time imaging of photoelectrochemical water splitting with a sub-nanometer spatial resolution by femtosecond lasers
Meng-Yu Weng,Pierre-Adrien Mante,Chi-Kuang Sun,

We used the femto-ultrasonics for real time imaging of photoelectrochemical water splitting process for the first time and got the structure and mechanical properties with a 0.5nm spatial resolution. We observed an extra solid-like layer between oxides and water in the chemical process.

CHUN CHIA HSU Award Candidate Fabrication of microlens on curved surface by using thermal reflow and replication
CHUN CHIA HSU,

Microlens array on spherical surface has attracted lots of interests due to the characteristic of wide field of view. In this paper, we propose fabrication of PDMS microlens on the curved surface by using thermal reflow technique and replication of metal model. The uniformity of microlens array was demonstrated through the intensity distribution of focused spots. And this process is simple and low-cost.

Meng-Chien Lee Award Candidate Recycle disposable heating pads as a visible light active photocatalyst for H2 revolution from water
Meng-Chien Lee,Chun-Yu Wang,Che-Chin Chen,Chih-Ming Wang,Din-Ping Tsai,

Alpha-Fe2O3 (α-Fe2O3) is cheap and abundant and has potential to be high efficientphotocatalyst for water splitting.According to the report, there are huge amount of disposable heating padsarebeing created every year, and only have one time use then thrown away. We found that the main product of used heating pads is α-Fe2O3. In this paper, we can use simple experiment setup to generate H2 without adding any electrolyte and sacrificial reagent. Through the experiment, it is found that with a little amount of α-Fe2O3 powder it can harvest lots of energy we need. It is shown that the recycle heat pads can be as cost-effective photocatalyst for H2 energy.

Wen Ting Hsieh Award Candidate Plasmonic Photocatalyst for Photodegradation with Spinning Optical Disk Reactor
Wen Ting Hsieh,Yu Lim Chen,I Da Chiang,Li Chung Kuo,Min Lun Tseng,Hao Ming Chen,Chih Kai Chen,Hung Ji Huang,Ru Shi Liu,Din Ping Tsai,

An efficient and novel photocatalytic reactor for environmental treatment was fabricated with zinc oxide nanorods growing on optical disk substrate as the photocatalyst. Plasmonic photocatalysis was also demonstrated to enhance the photodegradation efficiency.

Ting-Yi Wu Raman Signal Enhancement of Trilayer MoS2 by Using Gold Nanorods
Ting-Yi Wu,Hsiang-Yu Lin,Lain-Jong Li,Min-Hsiung Shih,

The enhancement of Raman spectrum of trilayer MoS2 by using gold nanorods. The effect of doping MoS2 by gold NRs is absence and verifies by Raman spectrum. The magnitude of enhancement with different density of NRs is not the same, and the intensity of enhanced Raman signal will saturate finally.

Ferry W Pranoto PHOTOLUMINESCENCE AND RAMAN SCATTERING OF DEGENERATE INN
FerryW Pranoto,Hao-Hsiung Lin,Zhe Chuan Feng,

We report on the photoluminescence (PL) and Raman scattering of InN grown by molecular beam epitaxy. The temperature dependent PL shows band to band and band to acceptor transitions with the features of heavily doped semiconductors. Raman scattering shows A1 and E2 modes, indicating the good crystallinity of the material.
