1989年3月23日にユタ大学とサザンプトン大学の2人の研究者によってアナウンスされたcold fusion(常温核融合)の可能性は,comfusion(condenced matter confinement nuclear fusion)と呼ばれ,もし実際に起りうるとすれば今世紀有数のトピックスとなる。一方,ミュオン核融合の研究は10年以上の歴史を持ち,ブリガムヤング大では,これに類似の現象が観測されたと主張する。 本稿は水素エネルギーの立場から,金属水素化物と重水電解系の界面でのダイナミックな非平衡系で核融合が可能なことを提唱する。この現象は,まだよく知られていないこともあって,特に今日までのcold fusion研究の経緯について述べ,理解を容易にした。 要点はcold fusionは優れて表(界)面の特徴的現象でsurfusionとも呼ばれてよいことも併せて提案した。

Topological insulators are insulating in the bulk, while there are topologically protected edge/surface states. These edge/surface states are different from conventional edge/surface states, and show various novel properties. We briefly outline basic properties of topological insulators, both in 2D and 3D.

Widely well-defined Si(110)-16×2 single-domain surface has been fabricated utilizing the electromigration of the surface atoms. Tuning the direction of the dc during resistive heating to that of the surface reconstruction row realizes an alignment of the rows in one direction producing a mm-wide single-domain of 16×2 structure. The fabricated single-domain shows number of useful characteristics such as a strong one-dimensionality and the surface homochirality, suggesting various applications.

An FET sensor is an integrated device of the insulated gate field effect transistor (IGFET) and the chemical sensor and therefore is named as chemically sensitive field effect transistor (CHEMFET). In the CHEMIFET, the gate metal is replaced a more complex structure having chemically sensitive layer. CHEMFETs are new type of chemical sensors and have potential advantages over conventional chemical sensors in miniatuarization, robust solid state nature, mass productivity etc. According to the nature of the interaction between the species to be detected and the chemically sensitive layer, CHEMFETs can be divided into two groups : one that will measure gas concentrations, for example Pd gate FET (H2 gas sensor) and the other that will measure ion concentrations in the solution. The latter called an ion sensitive FET (ISFET). This paper describes the present status of ISFET, that is, its histoical survey, principle, fabrication method and ion selectivities.

A practical chemical sensor has been demanded for decades in various fields, such as medicine, security, and environmental science. Recently, the comprehensive optimization of materials science, mechanics, crystallography, and electronics led us to an effective sensing platform; a piezoresistive nanomechanical membrane-type surface stress sensor (MSS). The unique structure of the MSS makes it possible to fulfill the requirements for a practical sensor; high sensitivity, high mechanical/thermal/electrical stability, high reproducibility, simple operation, small size, and compatibility with mass production. Since MSS can detect almost any kind of molecule ranging from gaseous to biological species in various conditions including ambient air or opaque liquids such as blood, MSS is expected to realize a practical chemical sensor for real life applications; for example, private real-time blood test, landmine detection, pollution monitoring, and breath diagnostics using a mobile phone.

Recent advance in semiconductor hetero-structure formation technology using crystal growth enabled us to form quantum wires and quantum dots, as well as quantum wells. Here, we review the quantum wire formation technologies which confine an electron or a hole within one-dimension, and their physical properties and device applications. We also introduce recent progresses of semiconductor nanowire fabrication by using crystal growth and their device applications.

Surfaces of some compliant materials, whose surface layers are harder than the bulk, sometimes form wrinkles with a stripe pattern. The wrinkles have potential impacts on the nanotechnology because the spatial wavelength can be small as submicron scales. The microwrinkles can rearrange in response to the mechanical perturbation, e.g., compression. Here, we focus on a hysteretic behavior of the microwrinkles under a slow cycle of compression and decompression. The local stripe directions change to the compression direction one after another as compression proceeds. However, the stripe patterns upon compression are different from those upon decompression, showing hysteresis in the pattern. We propose a simple phenomenological model that resembles Ising spin models, to understand the basic mechanism of the hysteretic behavior. The model suggests that the hysteresis in the pattern can be caused by the direct coupling between elements.

The adsorption of naphthalene on a Si(100)-2×1 surface at room temperature was investigated using infrared absorption spectroscopy (IRAS) in the multiple internal reflection geometry (MIR). To determine the adsorption configurations on the surface in detail, IRAS spectra in the C-H stretching vibration region were analyzed in comparison with calculations based on the density functional theory. As a result, it was found that naphthalene adsorbs on the surface in different manners depending on the surface coverage of the molecules. At low coverage, a single configuration is favored, in which the 1, 4, 6, 9 carbon atoms of a naphthalene molecule are bound to the dangling bonds of two adjacent Si dimers to form sp3 bonds. At high coverage, on the other hand, the molecules adsorb in several energetically preferred configurations. Furthermore, the effect of coupling of vibration modes between two adjacent molecules adsorbed on the surface was observed at high coverage.

地球上には約500万~3000万種の生物が生存している。日本には植物だけでも7451種の陸上植物(5016種の被子植物,46種の裸子植物,623種のシダ植物,そして1766種のコケ植物)が生育している。しかしながら,それらの1/4は絶滅危惧植物に指定されており,その原因は大きく2つに分ける事ができる。1) 蛇紋岩地などの特殊な環境に生息し,もともとの個体数が少ない種と,2) 本来は多く生育していたが,人間によってその減少がもたらされた絶滅危惧種である。たいていの植物の減少は2)の人類による環境の破壊によってもたらされたが,一方,その修復をできるのも人類だけである。「生物の多様性とこれからの社会」はどうあるべきか,今後,我々人類が考えていかなければならない大きな命題である。

We have developed optical sum frequency (SF) and second harmonic (SH) microscopy as a new surface probe. In this paper, recent three studies performed by the SF (SH) microscopy are presented. (1) The spatial distribution of electronic states of an arsenic ion implanted Si(111) substrate was observed by using a wavelength tunable SH microscope. Resonant SH images associated with Eg and E2 energy gaps were obtained at the SH photon energies of 2.33 and 4.43 eV, respectively. (2) It was demonstrated that the spatial distribution of hydrogen desorption by laser pulses from a hydrogen terminated Si surface can be observed by the SH microscope. In the case of irradiation of ultraviolet short laser pulses, the hydrogen desorption occurred above the threshold fluence of ∼40 mJ/cm2, suggesting that the hydrogen desorption probably resulted from the laser induced thermal desorption (LITD) mechanism. (3) It was demonstrated that nondestructive chemical analysis of starch granules in a water plant can be performedby using SH and SF microscopy.

Japan is facing a challenge of wide-spread radioactive contamination by isotopes of cesium (Cs). Here we demonstrate that titanium oxide (TiO2) can be an efficient material to immobilize high concentrations of Cs ions in a durable solid-state framework. TiO2 was dissolved in a Cs-containing melt of molybdenum trioxide (MoO3) at 950oC. The melt was then electrolyzed at −1200mV (vs. a Pt reference electrode) to obtain a single-crystalline titanate, Cs0.169TiO2 (titanium-oxide immobilizer) , which contained 1g cm−3 of Cs. Moreover, the titanium-oxide immobilizer exhibited a 170 times lower Cs leaching rate than did Cs-containing borosilicate glass. The titanium-oxide immobilizer will contribute to the Cs decontamination because of its high Cs content and low Cs leaching.

The hair has a complicated hierarchical structure which is composed of hydrophobic and hydrophilic components. Study of the mechanical properties of each components is important in order to understand the structure of the hair microscopically and to develop hair care products. The objects of this study are to evaluate the mechanical properties and fine structures of human hair at the same point and under the natural environment by taking the advantages of Atomic Force Microscopy (AFM). The force-curve method using stiff cantilevers in order to deform a sample by AFM enable us to evaluate Young's modulus and a fine structure simultaneously at the same point. In this study, we applied this method also to the cross section of the hair in order to evaluate the degree of hair damage. In an application we found that the Young's modulus was improved when the damaged hair was treated by L-theanine solution and that especially Young's modulus of macrofibril was recovered. This method is thus very useful to appraise the effectiveness of hair care components.

Relaxor type ferroelectrics are treasure boxes both for basic physics and practical applications. Among them, Ba(Zr, Ti)O3 is one of the candidate materials for elucidating the mechanism of relaxor phenomena. It has homo-valent B-site ions of Zr4+ and Ti4+. Therefore, there is no driving force to push the ions into ordered structure. On the other hand, it has a possibility of co-existence of multi phases (so-called pinching effect). In case of the bulk state, we have found that the relaxor behavior is strongly affected by the annealing conditions. To make clear the intrinsic parameter for the relaxor, we have demonstrated the artificial control of the positioning of the B-site ions by the superlattice technique. The stacking periodicity and the compositional combination of BaTiO3 and BaZrO3 are changed systematically with this method and the sign of the relaxor is detected.
