- Abstract
- The Taiwan APCST contract beamline BL12XU is part of the Taiwan x-ray facility at SPring-8, and is dedicated for inelastic x-ray scattering (IXS) with variable energy resolution from high (0.1−1 eV) to ultra-high (1−10 meV) resolution regimes. A secondary purpose is for high Q-resolution scattering and x-ray physics and optics. The Phase I construction of the beamline was completed in November 2001. The commissioning of the undulator and front-end components was carried out successfully in early December, together with the hutch radiation survey. The beamline has since been approved for commissioning. In the present article, we will briefly describe the scientific program, the key concepts and components of the beamline, the IXS spectrometer, and the initial commissioning of the beamline.

- Abstract
- We propose a new X-ray methodology for direct observations of the behaviors of single molecular units in real time and real space. This new system, which we call Diffracted X-ray Tracking (DXT), monitors the Brownian motions of a single molecular unit by observations of X-ray diffracted spots from a nanocrystal, tightly bound to the individual single molecular unit in bio-systems. DXT does not determine any translational movements, but only orientational movements. Recently, time-resolved dynamical X-ray imaging of individual DNA molecules with picometer-scale precision is demonstrated using DXT for the first time. DXT can obtain information about the dynamics of single molecules through a quantitative analysis, since the signals from DXT are independent of the chemical conditions.

- Abstract
- BL28B2 is a beamline for multi-purpose experiments using white x-rays and has been opened to the public since the 9th cycle of 1999. The equipment in the optics hutch 2 was primarily optimized for a state-of-the-art x-ray diffraction imaging including white x-ray topography. In this report we describe the current status of the beamline, the experimental appliances for topography and some experimental results.

- Abstract
- Catalytic converters are widely applied to control automotive emissions, such as nitrogen oxides, carbon monoxide and unburned hydrocarbons. In actual catalysts, however, the catalytic activity deteriorates owing to the particle growth of precious metals during vehicle use. An ageless catalyst is a kind of philosopher’s stone in automotive engineering. Referring to the wisdom of ancient Indian philosophy and medical science, Ayur Veda, we have developed a new self-regenerating perovskite-based catalyst. The perovskite catalyst, LaFe0.57Co0.38Pd0.05O5, regenerates itself without any auxiliary treatment, in direct reaction to the natural fluctuation between reductive and oxidative atmospheres in the exhaust gas from state-of-the-art gasoline engines. As palladium reversibly moves back and forth between inside and outside of the perovskite crystal, the particle growth of palladium can be suppressed. Such a self-regeneration provides new insight into the development of future automotive catalyst, as an intelligent catalyst.

- Abstract
- We developed the wavelength-dispersive total reflection x-ray fluorescence (WD-TXRF) equipment for the ultratrace element detection on semiconductor wafers. In combining the equipment with the extremely strong x-ray of BL40XU at SPring-8, we studied the relation between the detection limit and the measurement conditions. As a result, together with the concentration techniques for semiconductor wafer, remarkable detection limit of 4x106atoms/cm2 has been achieved for Ni and Cu elements for the first time.

- Abstract
- The construction of the exclusive beam-line (Pharmaceutical Industry Beam-line), BL32B2, of The Pharmaceutical Consortium for Protein Structure Analysis (PCProt), composed of 22 pharmaceutical companies affiliating with the Japan Pharmaceutical Manufacturers Association (JPMA), has been completed on May 16th, 2002, without any delay. In this report, process of the construction, activity of PCProt and the schedule of the operation is described. Normal operation, so called users mode, of the Pharmaceutical Industry Beam-line would be started since this autumn.
