A Tale of Two Mounts: The History of Chemistry at the Hebrew University of Jerusalem

This is the story of the establishment of the Hebrew University (HU), and within it, the sub-story of the first school of chemistry in the Land of Israel, from 1923. It spans more than 100 years, from the publication of the pamphlet, Eine Jüdische Hochschule, in 1902, all the way to 2015. The story starts with a dream, almost in the realm of science fiction, the audacious vision of building a university in a stateless and impoverished region, and all the way to an Institute of Chemistry of HU that has served as the mother of chemistry in the State of Israel.     

结构化学多媒体教学的实践体会

随着计算机技术的不断发展,多媒体教学已经越来越广泛的被使用。虽然在此过程中多媒体教学暴露出了一些的问题,但不能因此就否定它在教学中发挥的重要作用。作者认为解决问题的关键一方面是精心设计、制作真正有利于课堂教学的课件,另一方面还要注意该方法的合理应用。结合五年的结构化学多媒体教学实践,作者从如何看待多媒体教学、多媒体课件制作和多媒体教学应用中需要注意的问题谈了几点自己的看法。     

Topics in Structural Chemistry through After-Dinner Humor

Some of the best stories told by Jack Dunitz in after-dinner speeches introduce comments and personal views on aspects of contemporary structural chemistry: crystal structure analysis and prediction, facts and fallacies in the study of intermolecular bonding, and theories of crystal formation, from nucleation to growth. The role of X-ray crystallography in the determination of the structure of matter at a molecular level is highlighted, with broad and pervasive bearings on present-day applications in materials science. A short essay presents the results of molecular simulations on the stability of small molecular clusters with crystalline structure: the future seems to lay not in the analysis of crystal structures after they are formed, but in the study of autocatalytic insurgence of long-range ordering during nucleation processes.

Physical-Organic Chemistry: A Swiss Army Knife

“Physical-organic chemistry” is the name given to a subfield of chemistry that applies physical-chemical techniques to problems in organic chemistry (especially problems involving reaction mechanisms). “Physical-organic” is, however, also a short-hand term that describes a strategy for exploratory experimental research in a wide range of fields (organic, organometallic, and biological chemistry; surface and materials science; catalysis; and others) in which the key element is the correlation of systematic changes in molecular structure with changes in properties and functions of interest (reactivity, mechanism, physical or biological characteristics). This perspective gives a personal view of the historical development, and of possible future applications, of the physical-organic strategy.

Structural,electrical and magnetic behavior of mechanothermally synthesized multidoped bismuth ferrite

Some lead-free compounds of a general formula (Bi_1-xSr_x)(Fe_1-xMn_x)O₃ (x?=?0–0.15 with the interval of 0.05) were prepared by a mechanical alloying followed by sintering process. Structural, electrical and magnetic characteristics of multi-doped elements (Sr-Mn) in bismuth ferrite have been examined at different field frequencies and temperatures. X-ray diffraction studies suggest the rhombohedral phase for x?≤?0.1 and the orthorhombic phase for x?=?0.15. Study of frequency-dependent dielectric properties showed the enhancing trend of dielectric constant with increasing co-doping concentration. Detailed analysis of impedance data at different frequencies and temperature estimated the contribution of grains and grain boundaries in the capacitive and resistive properties of the studied samples. The study of magnetic properties exhibits the weak ferromagnetism in co-substituted samples with maximum saturation magnetization (M_s = 0.121?emu/gm) for higher concentration of doping (x?=?0.15). The magneto-electric coefficient (α_ME), measured with the varying DC magnetizing field under fixed AC magnetic field, is found to be 15.368?Oe.

Structural Chemistry: The Last 50 Years as Seen by an X-ray Crystallographer

Some aspects of the evolution of structural chemistry are described from the personal perspective of a student of Jack Dunitz who started working for a Ph.D. in crystal chemistry in the mid-1960s. The importance and the change of emphasis of X-ray crystal structure determination through the decades is sketched and related to technological advances. Activities beyond standard structure determination by single-crystal and powder diffraction, some of them significantly underdeveloped, are indicated. While crystal structure determination has become an important, if not indispensable, analytical tool supporting the widespread objectives of the synthetic chemists, structural chemistry has also developed a deep physical understanding of the concept of structure at the atomic length scale and enabled the organization of an enormous volume of individual observations based on the notions of chemical bonding.
