The causes of recurrent spontaneous abortion (RSA) and fetal malformations are multifactorial and unclear in most cases. Environmental, maternal, and genetic factors have been shown to contribute to these defects. Whole-exome sequencing (WES) is widely used to detect genetic variations associated with human diseases and has recently been successfully applied to unveil genetic causes of unexplained recurrent spontaneous abortion (URSA) and fetal malformations. Here, we review the current discovery and diagnosis strategies to identify the underlying pathogenic mutations of URSA and fetal malformations using WES technology and propose to further develop WES, both to advance our understanding of these diseases and to eventually lead to targeted therapies for reproductive disorders.

T At the forefront of energy storage field, developing sodium ion batteries （SIBs） has drew a wide concern due to relatively low cost and abundant resource, comparing with lithium ion batteries （LIBs）. Serious volume expansion constraints the electrochemical performance of the conver- sion/alloying materials, despite of their high reversible capacities or theoretical capacities. Here, from the perspective of structural designs, we systemat- ically study four types of routes to accommodate volume expansion. Delicate and peculiar nanostructures based on nanocrystallization engineering are widely focused on, covering nanosheet assembly and nanoarray construction. Robust materials such as carbon-based materials can be utilized as the buffer matrix, mitigating the mechanical stress during the charge/discharge process. Besides, recent studies have demonstrated void space reservation in nanostructures was also beneficial for adapting to volume changes. Moreover, for conversion materials, numerous works have confirmed the advanta- geous influence of interlayer spacing regulation. We also explained the superiority and challenges for further giving scope to structural designs. Sketching out the future studies in SIBs, in situ characterizations are supposed to be highlighted, as well as in-depth researches on the stress evolution caused by volume expansion.

A first principle method, based on the density functional theory, was used to investigate the average voltage of lithiation/delithiation for Li-ion battery materials across 7 categories and 18 series, including LiMO 2 , LiMn 2 O 4 , LiMPO 4 , Li 2 MSiO 4 and graphite. The average voltage of lithiation/delithiation in the relevant electrode materials was obtained by comparing the total-energy difference, before and after an electrochemical reaction. The calculated values were in good agreement with experimental data. The systematic difference between the simulated and experimental values could be explained in terms of the binding energy on the surface of the lithium electrode. This type of calculation method could be applied as an easy and effective tool for predicting the potential performance of new lithiation/delithiation materials.

Arsenic being one of the most toxic heavy metals has long been a focus of concern due to its gravest threats to human health and environment. Herein, we employ a new method named ring-opening click reaction to synthesize thiol- and amino- bifunctionalized SBA-15 (denoted as bi-SBA-15) for directly remove As(Ⅲ) without preoxidation As(Ⅲ) to As(V) from contaminated water. Quite different from commonly modified with trialkoxysilanes, ring-opening click reaction is substantially faster (0.5–2 h at 25 ℃) and more efficient. The synthesized bi-SBA-15 exhibits excellent adsorption performance of As(Ⅲ) and As(V) in an aqueous solution with a great adsorption capacity (33.70 mg/g and 42.66 mg/g, respectively), a very short equilibrium time (<30 min), which is much faster than those of other adsorbents reported previously. The excellent adsorption performance of bi-SBA-15 can be maintained with a wide pH range (3–8), various anions and natural organic matter, which provides an effective approach and a new insight to clean arsenic-contaminated water.
