Calcium is critical to a wide range of physiological processes, including neurological function, immune responses, and muscle contraction in the heart. Calcium-dependent signaling pathways driving these functions enlist a variety of proteins and channels that must rapidly and selectively bind calcium against thousand-fold higher cation concentrations. Frequently these pathways further rely on co-localization of these proteins within specialized subcellular structures to function properly. Our lab has developed multi-scale simulation tools to understand calcium homeostasis and its dysregulation at the molecular through systems levels. Applications include molecular simulations to predict protein-protein interactions, reaction-diffusion simulations that leverage high-resolution microscopy data and computer vision techniques to characterize morphological differences in cells important e payment electricity bill maharashtra to their function. In this seminar, I will describe these tools and their applications to a calcium-dependent signaling pathway driven by calmodulin and calcineurin activation, which is important in cardiac development and hypertrophy.

Two-dimensional (2D) materials with a thickness of a few nanometers or less can be used as single sheets, or as building blocks, due to their unique properties and ability to assemble into a variety of structures. Graphene is the best-known example, but several other elemental 2D materials (silicene, borophene, etc.) have been discovered. Numerous compounds, ranging from clays to boron nitride (BN) and transition metal dichalcogenides, have been produced as 2D sheets. By combining various 2D materials, unique combinations of properties can be achieved which are not available in any bulk material. The family of 2D transition metal carbides and nitrides (MXenes) has been expanding rapidly since the discovery of Ti3C2 in 2011 [1]. Approximately 30 different MXenes have been synthesized, and the structure and properties of numerous electricity labs for middle school other MXenes have been predicted using density functional theory (DFT) calculations [2]. Moreover, the availability of solid solutions on M and X sites, control of surface terminations, and the discovery of ordered double-M MXenes (e.g., Mo2TiC2) offer the potential for synthesis of dozens electricity hero names of new distinct structures.

This presentation will describe the synthesis of MXenes by selective etching of layered ceramic precursors, including various MAX phases. Delamination into single-layer 2D flakes and assembly into films and 3D structures, as well as their properties will be discussed. Synthesis-Structure-Properties relations of MXenes will be addressed on the example of Ti3C2.

The versatile chemistry of the MXene family renders their properties tunable for a large variety of applications [3]. Oxygen or hydroxyl- terminated Menes, such as Ti3C2O2, have been shown to have redox capable transition metals layers on the surface and offer a combination of high electronic conductivity with hydrophilicity, as well as fast ionic transport [4]. This, among many other advantageous properties, makes the material family promising candidates for energy storage and related electrochemical applications [5], but applications in plasmonics, electrocatalysis, biosensors, water purification/ desalination and other fields are equally exciting. In particular, capacitive deionization and membrane desalination and purification will be addressed.

The research program in the Allbritton Lab is a multidisciplinary effort that brings to bear principles and techniques from chemistry, physics, engineering, and materials science to develop new assays and technologies for hp gas online booking hyderabad biomedical applications. The ongoing work in the lab comprises three major focus areas: analytical techniques for single-cell biochemical assays, microfabricated platforms for sorting and cloning cells, microengineered systems for recapitulating organ level function. These applications utilize microengineered platforms (microfluidic and array devices) to manipulate and analyze living cells particularly targeting the intestinal epithelium or tumor systems. For example, we have developed gas in babies simple, inexpensive fabrication methods utilizing photoresists, plastics, and hydrogels for cell-based arrays, organ-on-chips, and tissue scaffolds. The fabricated devices include detachable, deformable, or biodegradable array elements designed for cell analysis and sorting. Another example exploits recent advances in mating living cells with microfabricated systems making it possible to create miniaturized devices with organ level function. These “organ-on-a-chip” platforms enable the controlled establishment of multicellular tissue-like cell populations from primary human cells.

Abstract: Access to global public healthcare is impacted by many technical, economic, and social factors. It is widely recognized that the resources required to deliver and improve global public health are currently constrained. A powerful way to increase access is to lower the cost of products and services that have already proven to be effective. Currently, the cost of producing a wide range of pharmaceutical products is higher than it needs to be. The mission of Medicines for All (M4All) is to transform the active pharmaceutical ingredient (API) processes in order to reduce medication cost and improve patient access. To fulfill this objective, M4ALL has developed a set of core principles for API process development, which is derived from fundamental elements of process intensification that are commonly known but often neglected. These principles have been applied to several global health drugs yielding dramatic improvements in chemical efficiency. The development of novel heterogeneous cross-coupling f gas regulations r22 that support this effort will also be presented.
