The measurement of the microwave field is crucial for many developments in microwave technology and related applications. However, measuring microwave fields with high sensitivity and spatial resolution under ambient conditions remains elusive. In this work, we propose and experimentally demonstrate a scheme to measure both the strength and orientation of the microwave magnetic field by utilizi...

QUESTION Several of my patients quote recent media coverage claiming that working with home appliances could increase the risk of misarriages. What is your advice? ANSWER Two recent epidemiologic studies from California have suggested an increased risk of miscarriages associated with exposure to magnetic fields. Even if the threshold associated with such risk is a biologic and true risk (and ...

An efficient synthesis of 3-substituted or 2,3-disubstituted 4(3H)-quinazolinones from benzoxazin-4-ones and primary amines under microwave irradiation in unsealed vessels is described.

Phthalocyanine complexes of Cu, Co, Ni, Fe, Zn, Pd, Pt and Ru have been synthesized from reaction between phthalonitrile and proper metal salts upon exposure to microwave irradiation under solvent-free conditions and considerably reduced reaction times.

Cryo-electron microscopy (cryo-EM) plays an increasingly more important role in structural biology. With the construction of an arm of the Chinese National Protein Science Facility at Tsinghua University, biological cryo-EM has entered a phase of rapid development in China. This article briefly reviews the history of biological cryo-EM in China, describes its current status, comments on its imp...

UNLABELLED In 1991, the American Boards of Internal Medicine and Emergency Medicine changed their credentialing requirements to recognize training common to both disciplines. This allowed the formation of a five-year track for dual board eligibility. From 1995 to 1998, 28 physicians graduated from eight emergency medicine/internal medicine (EM/IM) programs. This study was an analysis of career ...

Optical “nano-manipulation” to control small objects with nanoscale precision requires strongly localized optical fields that are usually based on user-imposed shaping of the incident optical beam. Here we report an in situ approach to reshape and enhance electromagnetic (EM) fields using scattering and interference that is concomitant with “dynamic self-assembly” of nanoparticle arrays using s...

Magnetic-dipolar modes (MDMs) in a quasi-2D ferrite disc are microwave energy-eigenstate oscillations with topologically distinct structures of rotating fields and unidirectional power-flow circulations. At the first glance, this might seem to violate the law of conservation of an angular momentum, since the microwave structure with an embedded ferrite sample is mechanically fixed. However, an ...
