Grounded Theory Review: An International Journal, 2009
We’ve had a great response to our June issue focusing on the novice experience of doing classic grounded theory (GT). This is no doubt indicative of the number of new researchers seeking to understand and apply the classic methodology for grounded ...

2D Co‐Assembly of Solid Acids Enables Stable Superprotonic Conduction Above 260°C

Advanced Functional Materials, EarlyView.
A two‐dimensional co‐assembly strategy integrates antimony phosphate and phosphotungstic acid nanosheets into free‐standing inorganic lamellar membranes with confined acid–acid interfaces. The resulting interfacial hydrogen‐bond network enables anhydrous proton conductivity exceeding 0.1 S cm−1 at 260°C and supports stable high‐temperature fuel‐cell ...

Practical Attacks and Defenses of MIFARE Classic

, 2013
MIFARE Classic是近年來最廣泛被使用的非接觸式智慧卡，應用在門禁、大眾運輸工具、電子錢包等系統上。MIFARE Classic上密碼保護機制與結構已被發表在許多的論文上。在本論文中我們提出各式各樣在MIFARE Classic攻擊實作的經驗。我們實作兩類的攻擊:一是假造讀卡機、二是側錄合法的交易。第一類的攻擊在兩天內利用NVIDIA高速運算顯示卡上實作密鑰的窮舉搜尋法與隨機數和連認證的漏洞離線的破解卡片上所有的金鑰。第二類是針對MIFARE Classic加解密器: CRYPTO ...

Designing Vanadium‐Based Oxide Electrocatalysts for Water Splitting: Experimental and Mechanistic Insights with Machine Learning

Advanced Functional Materials, EarlyView.
This review establishes structure‐property‐mechanism relationships across six modification strategies for V‐based oxide water‐splitting electrocatalysts: lattice engineering, heteroatom doping, interface engineering, carbon‐based hybridization, morphology engineering, and surface reconstruction and pre‐catalyst design, where dissolution is reframed as ...

Photo‐Switchable Molecular Module Programming PET Biodegradation in Aquatic Environments

Advanced Functional Materials, EarlyView.
We address the plastic durability paradox by integrating an itaconic acid–derived pyrrolidone module into polymer backbones. Sunlight in water triggers Norrish Type I ring‐opening and hydrophilization, enabling rapid biodegradation into nontoxic minerals.

Bioinspired Hydrogels with Broadly Programmable Mechanics for Soft‐Tissue Interfaces

Advanced Functional Materials, EarlyView.
Sea cucumber‐inspired gelatin hydrogels are formed by directional freezing and mechanically programmed through subsequent ionic treatment. Multiscale characterization and modeling link ion‐regulated chain interactions to directional load transfer within the aligned hierarchical architecture.
