Three-dimensional (3D) integration with through-die vias offer improved electrical performance compared to edgeconnected wire bonds in stacked-die assemblies. Monolithic wafer-level 3D integration offers the potential for a high density of micron-sized through-die vias necessary for highest performance of integrated systems. In addition, such wafer-level technologies offer the potential of lowe...

The development of the parameters of ozone decontamination method assuring the least possible losses of biologically active substances (essential oils and polyphenols) and their activity in common juniper (Juniperus communis (L.)) berries was studied. Ozone treatment in dynamic bed was conducted 9 times. The process was conducted under different ozone concentrations (100.0; 130.0; 160.0 g O3/m3...

This study aims at investigating a polymer-based air-gap creation method for the packaging of microelectromechanical systems (MEMS), and exploring the chemical composition of the polymer residue on the final package. Polymer-based air-gap formation utilizes thermal decomposition of a sacrificial polymer, poly(propylene carbonate) (PPC), encapsulated within an overcoat polymer. BCB (Cyclotene 40...

Over a million prosthetic joints are placed in patients in the United States annually. Of those that fail, 25% will be due to infection, with an estimated cost approaching 1 billion dollars. Despite the clinical and economic importance of these infections, the techniques for their detection are relatively insensitive. An innovative method for detecting these infections by using blood culture bo...

Organic transistor technology holds great promise for creating a conformal, human-safe electronic neural interface. These interfaces must amplify the low, microvolt-range brain signals so they can be utilized in analog and digital applications. Brain signals from sensors must be relayed to the transistor’s gate through the dielectric and semiconductor layers, as well as through an encapsulant w...

Microshoot cultures of the Chinese medicinal plant Securinega suffruticosa (Pall.) Rehd. were established and evaluated for the presence of therapeutically relevant indolizidine alkaloids securinine (S) and allosecurinine (AS). The cultures were maintained in shake flasks (SFs) and a bubble column bioreactor (BCB) using the modified Murashige's shoot multiplication medium supplemented with 1.0 ...

As MEMS transducers are scaled up in size, the threshold is quickly crossed to where magnetoquasistatic (MQS) transducers are superior for force production compared to electroquasistatic (EQS) transducers. Considerable progress has been made increasing the force output of MEMS EQS transducers, but progress with MEMS MQS transducers has been more modest. A key reason for this has been the diffic...

پژوهش حاضر به بررسی این مسأله می‌پردازد که چگونه نوعِ متد آموزشی می‌تواند بر میزان اضطراب زبانی دانشجویان زبان‌های خارجی تأثیر بگذارد. یک گروه 40 نفره از دختر و پسر در سطح پیش‌دانشگاهی به‌عنوان جامعه آماری انتخاب شدند. آموزش زبان فرانسه دو هفته‌ی اول، طریق گرامر-ترجمه انجام شد. پایان هفته تست تعیین مقیاس کلاس خارجی: FLCAS، بعمل آمد. دوم نوع رویکرد کنشی تغییر یافت. پس مجدداً فراگیران نتایج حاصله ن...

Benzocyclobutenes (BCBs) are of growing interest in materials and medicinal chemistry, although general routes for their provision remain underexplored. A modular, divergent, stereoselective Cu- Pd-catalyzed assembly/cyclization sequence allows the synthesis densely functionalized BCBs, from readily accessible imine, allene, diboron precursors. Preliminary results have identified enantioselecti...
