Tuberculosis (TB) has long been recognized as a disease of poverty, yet most TB research does not measure poverty in a meaningful way. A new review in the journal BMC Global and Public Health examines existing methods for assessing socioeconomic status in TB studies and highlights their shortcomings. The authors call for better, standardized poverty metrics to improve research and policy.
At a ceremony in Halle (Saale)/Germany to mark the transfer of office, economist Bettina Rockenbach assumed the office of President of the German National Academy of Sciences Leopoldina today. Her predecessor, climatologist Gerald Haug, is stepping down after five years in office. In his speech, the Federal Minister of Education and Research as well as Food and Agriculture Cem Özdemir commended Gerald Haug’s services during challenging times. Özdemir referred to the independence of science as a precious asset and wished Bettina Rockenbach a successful start to her leadership of the Academy. Thomas Wünsch, the State Secretary of the Ministry of Science, Energy, Climate Protection and the Environment of Saxony Anhalt, gave a welcome address.
Professor Can Wang from Tianjin University and Professor Zhurui Shen from Nankai University have achieved significant results in their collaborative research. In this study, monolayer Ti3C2Tx was prepared by etching and exfoliating Ti₃AlC₂, and then TiO2/monolayer Ti3C2Tx (T/mT) was synthesized. The surface functional groups enhance the hydrophilicity and surface energy, and a Schottky heterojunction is formed with TiO2, which improves the photocatalytic activity. Meanwhile, the hybrid material can closely bind to Escherichia coli cells and has a high affinity for cell membrane proteins. Experiments show that it has a high charge separation and transfer efficiency, a strong photocurrent signal, and low impedance. In the photocatalytic reaction device, the sterilization efficiency of T/mT reaches 3.3 log in only 12.8 seconds, far exceeding that of TiO2. The various components and chemical bonds of cells have been damaged to varying degrees by active substances. This achievement points the way for the molecular structure design of photocatalytic air disinfection technology and is of far-reaching significance for promoting the progress of air disinfection technology.
Rossin College professors Jonas Baltrusaitis (chemical and biomolecular engineering), Xuanhong Cheng (bioengineering and materials science and engineering), Siddha Pimputkar (materials science and engineering), and Yahong Rosa Zheng (electrical and computer engineering) are among the six Lehigh University faculty members named Senior Members of the National Academy of Inventors (NAI).
