立方体卫星项目
365betapp下载有一个令人兴奋的正在进行的多学科研究项目. 罗兹要去太空了! 这是它的卫星. RHOK-SAT is a one unit CubeSat (a 4-inch cube) that will be launched in 2023 to investigate the degradation of novel photovoltaic materials in a space environment. 罗兹向NASA立方体卫星发射计划的申请于2021年4月被接受, 让RHOK-SAT进入轨道. 一个由十几名学生组成的团队目前正在从事有效载荷的设计和测试, 飞行软件开发, 以及地面站通信，为我们长达一年的任务做好准备. 我们欢迎有兴趣的学生加入这个研究项目. 点击这里阅读更多内容: 美国宇航局将发射365betapp下载斯设计的卫星进入太空.

静电学
的 interaction of two charged conducting spheres is a problem in classical electrostatics that has relevance in many natural and industrial phenomena such as the interaction of rain droplets in clouds, 灰尘附着于表面, 电子喷雾, 静电印刷, 等. 的 goal of this research is to understand this interaction at a fundamental level and develop mathematical approximations that 是 easy to use for quick and accurate calculations. 的 results can be used to simulate the dynamics of charged particles and for testing electrostatic (Laplace’s equation) solving softw是 against exact mathematical formulae.
数学物理
上面讨论的两球静电问题使用了朗伯级数的数学. 这个系列出现在许多其他物理和数学领域的数学中，比如超对称, 素数理论, 等. 的 research in this topic involves applying Lambert series results to new 是as of physics which involve similar mathematical structures.

超声后向散射在临床骨评估中的应用
Our research involves the development of ultrasonic techniques that can be used to detect changes in bone caused by osteoporosis. Osteoporosis is a degenerative bone disease that decreases the structural integrity of bone and increases the risk of fracture. Approximately 150 million people worldwide 是 at risk of osteoporotic fracture including hip fractures which 是 especially debilitating. 骨质疏松引起的髋部骨折的一年死亡率约为30%. 大多数髋部骨折的患者都无法恢复到受伤前的状态.
的 超声波研究物理实验室(PLUS) at Rhodes is pioneering new ultrasonic techniques that can be used to detect changes in bone and screen patients for osteoporosis. 具体来说，我们正在开发超声骨评估的后向散射方法. Backscatter measurements 是 performed by propagating ultrasonic pulses into regions of porous bone tissue called cancellous bone and then receiving the returned (backscattered) signal. 的 backscatter signals 是 analyzed in novel ways to estimate the density and microstructural characteristics of bone. Backscatter techniques may make it easier to perform ultrasonic measurements at clinically important skeletal locations such as the hip and spine where approximately two-thirds of osteoporotic fractures occur. 也, it may be possible to adapt ultrasonic imaging systems already in clinical use for other purposes to perform backscatter measurements on bone.

目睹环星系介质的信息:成像高电离氧在一个 破纪录的银河风 使用哈勃太空望远镜.
巨大而致密的星系 马卡尼可能是迄今为止发现的最大的由星暴驱动的星系风. 这 风(见视频) 很好地延伸到它的宿主星系的环星系介质(CGM)，并且是 cgm信息的快照. 马卡尼巨大而明亮的氧星云是成像温热CGM的理想目标, 这在大多数其他资源中是困难的. 在2021年和2022年期间， 我们正在拍摄第一部“重生片” 当暖热的CGM被马卡尼的强风重新形成时. 我们正在用哈勃太空望远镜(ACS/SBC)上的紫外照相机对马卡尼进行成像。. 的se observations 是 optimally-timed to meet simulated images of OVI that 是 emerging from the latest simulations. 的 morphology of the image and comparison with other data will constrain the physical state of the 气体 in the nebula through comparison with models and simulations of the wind-CGM interaction and shock+photoionization models.
Q-3D:詹姆斯·韦伯太空望远镜的类星体成像光谱
在过去几年里， 积分场光谱学 彻底改变了河外天文学. 其红外灵敏度、空间分辨率、光谱覆盖范围等都是前所未有的 詹姆斯·韦伯太空望远镜 能保证天文团体的高需求吗. 我们的团队, 包括365betapp下载的学生， 是 为社区提供一个新的光谱分析包 用于高动态范围JWST IFU观测. 发光的类星体, 它们明亮的中心源(类星体)和扩展的发射(宿主星系), 这个软件有优秀的测试用例吗. Quasars 是 also of high scientific interest in their own right as they 是 widely considered to be the main driver in regulating massive galaxy growth. JWST将彻底改变我们对黑洞-星系共同演化的理解，使我们能够探测恒星, 气体, 以及附近和遥远星系的尘埃成分, 空间和频谱. We will use the IFU capabilities of JWST to study the impact of three c是fully selected luminous quasars on their hosts.

捕获和传输流体中磁性颗粒的芯片实验室方法
Our modern world relies heavily on chip-based technologies for electronic items such as computers and cell phones. 在此之前的几十年里，这些芯片的生产取得了许多进步, and in turn humans have been able to make large quantities of chip-based electronic devices at increasingly low prices; there 是 now more cell phones than people. 近年来, 基于芯片的技术不仅用于电子领域, 而且在“芯片实验室”的微流体装置中，微型生物, 化学, 医学实验可以在硬币大小的芯片上完成. 这已经被用于, 例如, 从极少量的液体输入中检测病原体或核酸.
我们对一项与芯片实验室设备相关的技术感兴趣, 即芯片上的表面图案磁铁如何与水中的磁性颗粒相互作用, 或者“磁珠”. 的se patterned magnetic structures 是 smaller in width than a human blood cell and only a few hundred atoms thick, 但已经被证明能够捕获表面的珠子. 除了, 通过使用电磁铁来施加和改变磁场, 珠子可以通过可控的方式在表面上移动, 如下所示. 我们感兴趣的是这些相互作用背后的物理原理. 另外, 这种捕获和传输机制已经被证明在, 例如, 磁致微流体泵及稀有分子检测新方法, 我们正致力于开发这一强大而通用的工具的新应用.
