Engineering Compact Base Editors by AlphaFold‐Guided Mutation Scan and Escherichia coli‐Based Tri‐Selection

open access: yesAdvanced Science, EarlyView.
A miniaturized deaminase SsdAtox was scanned with AlphaFold to identify DNA binding pocket hot spots. Site‐saturation mutagenesis at gatekeeper residue K31 yielded ten‐fold activity enhancement. Trinity Screen, an E. coli‐based three‐in‐one platform selecting for high activity and reduced double‐strand breaks, enabled combinatorial evolution at DNA ...

Cation–Anion Synergy Enables Uniform and Stable SAMs for High‐Efficiency Perovskite/TOPCon Tandem Solar Cells

open access: yesAdvanced Science, EarlyView.
A cation‐anion synergistic strategy is developed to enhance self‐assembled monolayer (SAM) adsorption using guanidinium thiocyanate (GuaSCN). Guanidinium (Gua⁺) suppresses micelle aggregation, while thiocyanate (SCN−) promotes phosphonic acid deprotonation and strengthens ionic bonding to the substrate.

Ion Crowding Effect in Unilaterally Downsized Perovskite Memristors

open access: yesAdvanced Science, EarlyView.
The downscaling of perovskite memristors incorporating monocrystalline nanoplates is accompanied by an ion crowding effect, which greatly enhances the local electric field in the vicinity of electrode. The highly controlled crowding of anions and vacancies results in anisotropic switching characteristics as well as unique morphology modification ...

Engineered Bacteria‐Vesicle Delivered Lactate Reprogramming Boosts Tumor Radiosensitivity

open access: yesAdvanced Science, EarlyView.
We engineered a bacterial‐vesicular dual‐delivery platform that targets LOx to colorectal tumors, enabling lactate clearance, immune microenvironment remodeling, and microbiota modulation. This microbe–metabolism synergistic strategy effectively sensitizes colorectal cancer to radiotherapy, offering a promising approach to overcome radioresistance ...

胰岛素抵抗与非致残性缺血性脑血管病患者卒中复发之间的关系 Association between Insulin Resistance and Recurrent Stroke in Patients with Non-disabling Ischemic Cerebrovascular Events

open access: yesZhongguo cuzhong zazhi, 2019
目的 探讨不同胰岛素抵抗状态对无糖尿病史的非致残性缺血性脑血管病(non-disabling ischemic cerebrovascular events,NICE)患者卒中复发风险的影响。 方法 使用稳态模型胰岛素抵抗(homeostasis model assessment of insulin resistance,HOMA-I R)指数 对胰岛素抵抗进行评估。根据不同胰岛素抵抗状态,使用四分位法将无糖尿病史的NICE患者分为4 组。该研究的主要研究终点为90 d新发卒中(包括缺血性和出血性卒中)

Surface Engineering on Transition Metal Dichalcogenides: In Situ Encapsulation of Metal–Organic Frameworks for Highly Humidity‐Resistant Gas Sensing at Room Temperature

open access: yesAdvanced Science, EarlyView.
2D UiO‐66‐NH2/MoS2 was fabricated via an aqueous synthesis method to in situ encapsulation of MoS2 with 2D UiO‐66‐NH2 MOF. The humidity‐resistant NO2 sensing of 2D UiO‐66‐NH2/MoS2 at room temperature was accordingly enhanced by MOF encapsulation layer, along with the selectivity and stability.

Recycled Piezoelectric Materials with Competitive Second‐Life Functional Properties

open access: yesAdvanced Electronic Materials, EarlyView.
The essential piezoelectric ceramics with heavy ecological footprints are not sufficiently recycled. This work demonstrates the feasibility of recycling different types of piezoelectric ceramics using different binders, where the terpolymer binder with relatively large permittivity facilitated superior retention of properties after recycling, promoting
