每次出国旅行,我们都在使用标准化的组件。想象一下在1800年代坐火车出国旅行。当时的欧洲尚未引入标准化的铁路。因此,铁路工人不得不花费大量的时间和精力在边境线处将旅客和货物从一列火车转移到另一列。

对于3D打印的发展历史,我认为可以从以下三个阶段对这项新兴技术的发展进行分析。让3D打印可用对于从早期开始一直关注3D打印的人们来说,这项技术并非新兴事物。约30年前第一台3D打印机问世,当时的3D打印技术还在探索初期,Materialise的首席执行官Fried Vancraen先生在1990年购买了他的第一台3D打印机,但他发现这台打印机的打印质量并不好,打印高质量的部件也就无法保证。

This work involves an investigation of nanostructures, microelectronic properties and domain engineering of nanoparticles thin layers of Pb(Zn1/ 3Nb2/3)O3-PbTiO3 (PZN-PT) ferroelectric single crystals deposited on nanostructured silicon substrate. In this study, devices made from PZN-4.5PT nanoparticles thin films successfully deposited on silicon substrate have been studied and discussed. SEM images show the formation of local black circles and hexagonal shapes probably due to the nucleation of a new Si-gel component or phase induced by annealing. Micro Xray Fluorescence mapping shows that the high values of Si and B atoms (≅7 and 4 normalized unit respectively) can be explained by the fact that the substrate is p-type silicon. The most interesting result of optical measurements is the very good absorption for all the thin films in UV, Visible and NIR regions with values from 70% to 90% in UV, from 75% to 93% in Visible and NIR. Tauc plots present particularities (rarely encountered behavior) with different segments or absorption changes showing the presence of multiple band gaps coming from the heterogeneity of the thin films (nanowires, gel and nanoparticles). Their values are 1.9 and 2.8 eV for DKRN-Gel, 2.1 and 3.1 eV for DKRN-UD and 2.1 and 3.2 eV for DKRN-D) corresponding respectively to the band gap of nanowires and that of the gel while the last ones correspond to the undoped and doped nanoparticles (3.1 and 3.2 eV respectively).

The integration of ferroelectric materials as thin films has attracted considerable attention these last years thanks to their outstanding performances that allow considering new features for the realization of photovoltaic devices. Our study focuses on investigating structural, dielectric and ferroelectric properties of undoped and Mn doped PZN-4.5PT nanoparticles thin films on Silicon substrate. We fabricate very stable PZN-4.5PT nanoparticles thin films deposited on nanostructured silicon substrate with giant relative dielectric permittivity of 2.76 × 104 and 17.7 × 104 for respectively the undoped and Mn doped thin films. These values are very large compared to those found in single crystals and might be explained by the influence of the gel in which nanoparticles were dispersed. The SEM images show the crystallization of new hexagonal phases on the film surface probably coming from interaction between Si and the gel. The hysteresis loops permitted to determine the spontaneous polarization (Ps), remnant polarization (Pr) and coercive field Ec which are equal to 11.73 μC/cm2, 10.20 μC/cm2 and 20 V/cm, respectively for the undoped nanoparticles thin film and 22.22 μC/cm2, 19.32 μC/cm2 and 20 V/cm respectively for the Mn doped one. These values are high and correspond to the best ones found in literature compared to typical ferroelectric thin films.

Rare-earth ion doped crystals for hybrid quantum technologies are an area of growing interest in the solid-state physics community. We have earlier theoretically proposed a hybrid scheme of a mechanical resonator which is fabricated out of a rare-earth doped mono-crystalline structure. The rare-earth ion dopants have absorption energies which are sensitive to crystal strain, and it is thus possible to couple the ions to the bending motion of the crystal cantilever. This type of resonator can be useful for either investigating the laws of quantum physics with material objects or for applications such as sensitive force-sensors. Here, we present the design and fabrication method based on focused-ion-beam etching techniques which we have successfully employed in order to create such microscale resonators, as well as the design of the environment which will allow studying the quantum behavior of the resonators.

The idea to use ferroelectric materials (PZN-PT) came from the fact that the ferroelectric nature could facilitate electric charges accumulation on the interfaces of the solar cell. Thus, it would increase the open circuit voltage Voc which could reach more than 10 V. This would directly impact the efficiency which is proportional to Voc, thus hoping to obtain solar efficiency never equaled by the halide perovskites which are less stable and less resistant in aggressive environments. In this work, the solar cells produced gave an exceptional record efficiency of 39.32% with a very high open circuit voltage (Voc) of 3.50 V, a short-circuit current density (jsc) of 0.118 mA/cm2 and an FF of 0.72 measured in the positive polarization direction under 3825 lux (5.6 W/m2) lighting. The negative polarization direction under 4781 lux (7 W/m2) lightning gave a current density of 2 mA/cm2, an open circuit voltage of 2.30 V and an FF of 0.35.

Sodium valproate (VPA) is an anti-epileptic drug which was until now administered to children as drinkable or injectable form. A new galenic form of this compound has been developed asmicrogranules with prolonged release (Micropakine LP; MPK). This new galenic form of VPA allows a greater stability of the plasmatic rates, thus limiting the risk of amount-dependent adverse effects at the time of the peaks, and of less effectiveness at the time of the fall of the circulating rates. The main objective of this study was to evaluate the acceptability of the new galenic form of VPA, in monotherapy, for epileptic children with ≥ 3 years old. The evaluation was performed at day (D)90 by the patients using a hedonic visual scale. The secondary objectives were to evaluate the acceptability by the parents, the treatment compliance, the percentage of patients free of seizure at D 90, and the tolerance. Finally, the authors compared all these data to those recovered at the baseline in patients already treated by the previous drinkable VPA. A total of 307 patients were involved by 76 hospital neuropediatric physicians. The population was constituted by 110 children 5 years, P < 0.0001). Less difficulties were experienced by the parents to administrate MPK when compared to the drinkable form (P < 0.001), mainly due to his neutral taste. Patients free of seizure at D 90 were 77% 70,3; 82,5 . Specially, fewer epileptic seizures were evidenced for all children previously treated at D1 by drinkable form of VPA. The treatment was well respected by the patients, which were compliant in 80% of the cases. The adherence to treatment was good since the treatment compliance was 87%
