Chronic airway diseases, including asthma, chronic obstructive pulmonary disease (COPD), and bronchiectasis, impose a significant global health burden. A central unifying feature of these diseases is ...

This is part 1 of a 2-part series. As fall approaches in the northern hemisphere, like many of us who either follow an academic calendar for our work or have children in school, I'm preparing for a ...

The Nature Index 2024 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

While you can slip and fall at any point in life, it’s more common with age. More than 1 out of 4 older adults take a tumble each year, and about 20 percent of these falls lead to injuries such as ...

环氧丙烷(PO)是生产聚氨酯、聚酯、丙二醇等工业化学品的重要中间体。目前，生产PO的主要方法是氯醇法和共氧化法，这两种方法的加工过程都很复杂，而且容易产生多种有害副产品。以钛硅分子筛(TS-1)为催化剂，H2O2为氧化剂，甲醇(CH3OH)为溶剂的H2O2氧化生产PO ...

Balanced doors help create entrance systems that are unlike any other. From best-of-the-best aesthetics to extreme durability, effortless operation, and hardware designed for a lifetime of use, ...

Abstract: While III-V photovoltaics are among the most efficient, they suffer from a high manufacturing cost. One of the methods of reducing this cost is through GaAs substrate reuse, with a promising ...

Introduction: Reactive oxygen species (ROS)-mediated therapies have typically been considered as noninvasive tumor treatments owing to their high selectivity and efficiency. However, the harsh tumor ...

密度泛函理论计算模拟表明: 在碳基体中插入B-O物种可以显著提高其通过2e−氧化还原反应（ORR）电化学合成H2O2的催化性能，并且BC2O结构中的B原子表现为最活跃的位点，在吸附O2的氢化过程中获得最低的吉布斯自由能差（ΔG）0.03 eV；而没有与氧原子相连或者与两个氧原子相连的B原子则具有较大的ΔG（分别为0.08和0.10 eV）。
