Dr. 巴卡尔的物理学研究主要集中在磁性物质的测量上 设计并合成了一种叫做Heusler化合物的新型磁性材料 for spintronic applications. His interest in design materials attracted him to complete 他在北德克萨斯大学材料科学与工程专业接受的教育 (UNT). He received his Ph.D. degree at UNT in 2021 in investigation of porous ceramic structure by freeze-casting. 

他以物理系博士后教学研究员的身份加入了云顶集团 to work with Dr. Flanagan, Dr. Moldenhauer, Dr. Steinmiller, and collaborate with 燃气轮机热障涂层用氮化硅密封的铈实验室研究 extended engine life that funded by the Air Force. This project started in 2020 when Cerium Labs正在报告其STTR“第一阶段”资助的结果. Cerium lab group with the chief scientist Prof. Tim Hossain explored a patented silicon nitride seal 可以保护TBC，提高发动机性能，减少维护 and replacement costs. Dr. Bakkar started as a postdoctoral and the main researcher 在第二阶段与这个小组一起使用这项专利继续下去 在更大、更真实的TBC样本上追求这种技术. His research focuses 对tbc的面漆进行密封，以防止CMAS在高温下的攻击 利用化学气相沉积CVD技术沉积氮化硅牺牲层. 目前，他正在进行CMAS攻击测试，并对之前的tbc样本进行了表征 and after CMAS test using SEM at UD, XRD, and TEM at Cerium lab.

Research Interest

我的兴趣一直在于物理和材料方面的材料设计和表征 science and engineering fields. In the beginning, I focused on the measurement of 磁性材料的性质，设计和合成的新磁性材料 called Heusler compounds for spintronics applications. My love of research and improving 我在材料方面的表征技能引导我研究多孔陶瓷 structure by freeze-casting technique during my Ph.D. journey.  The design and fabrication 具有各向异性特性的多孔陶瓷材料近年来得到了广泛的研究 受欢迎的原因在于它们在各个领域的潜在应用，包括医疗， energy, defense, space, and aerospace. Freeze-casting is an effective, low-cost, and 安全的方法作为湿成型技术来创建这些结构. He worked to design 金属基复合材料mmc通过创建高度排列的多孔陶瓷结构 采用磁场辅助冷冻铸造和渗透多孔陶瓷预制体 with molten metal. 这项研究得到了陆军研究实验室(ARL)的支持 他成功地设计了轻质高抗冲击材料 designing Al/Al2O3 MMCs. 作为他在UNT研究的一部分，他设计了一个模型来缓解 Ca-Mg-Al-Si氧化物(CMAS)对热障涂层(TBC)的侵蚀 在喷气发动机和燃气涡轮发动机的叶片表面使用修饰 of the topcoat of TBC using laser treatment. Recently, I with my group at UD collaborated with Cerium lab on two projects. (I) a silicon nitride seal for thermal barrier coating in gas turbines for extended engine life funded by Air Force. (II) . Silicon Nitride 耐事故燃料防护涂层(ATF)，由美国能源部资助. The project goal 是为了保护锆合金包层表面的氧化，防止 formation of hydrogen gas with hot steam. I have practiced my favorite job throughout 我在特拉华大学度过了一年半的时间，在那里我一边教学一边做研究 time. 在教室和实验室与学生互动总是给我能量 and motivation to learn and teach.
