Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

Advanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

Biases in ice sheet models from missing noise-induced drift [PDF]

The Cryosphere
Most climatic and glaciological processes exhibit internal variability, which is omitted from many ice sheet model simulations. Prior studies have found that climatic variability can change ice sheet sensitivity to the long-term mean and trend in climate

High climate model dependency of Pliocene Antarctic ice-sheet predictions

Nature Communications, 2018
The mid-Pliocene warm period provides a natural laboratory to investigate the long-term response of the Earth’s ice-sheets and sea level in a warmer-than-present-day world.

Nitric Oxide‐Generating Poly (allylamine hydrochloride) Coating on Biomedical Titanium Implant

Advanced Materials Interfaces, EarlyView.
We report a metal‐free, nitric oxide (NO)‐generating coating in which poly(allylamine hydrochloride) (PAH) is covalently immobilized onto titanium. The coating catalyzes NO generation from the endogenous S‐nitrosothiol GSNO, retains activity after multiple reuse cycles and pH exposures, and maintains endothelial cell viability while modulating ...

Modelling water flow under glaciers and ice sheets [PDF]

Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2015
Recent observations of dynamic water systems beneath the Greenland and Antarctic ice sheets have sparked renewed interest in modelling subglacial drainage. The foundations of today's models were laid decades ago, inspired by measurements from mountain glaciers, discovery of the modern ice streams and the study of landscapes evacuated by former ice ...

Electrochemically Engineered PEDOT:PSS/MXene Composite Electrode for the Label‐Free Procalcitonin Detection

Advanced Materials Interfaces, EarlyView.
Procalcitonin is a key biomarker for bacterial infections, but conventional detection methods are often time‐consuming. Here, we present an electrochemical sensor based on highly conductive Ti3C2Tx MXene combined with PEDOT:PSS, enabling direct antibody immobilization, while a bovine serum albumin coating provides antifouling protection.

The paradigm shift in Antarctic ice sheet modelling [PDF]

Nature Communications, 2018
The Antarctic ice sheet is one of the largest potential contributors to future sea level rise. Predicting its future behaviour using physically-based ice sheet models has been a bottleneck for the past decades, but major advances are ongoing.

Responces of melting below Antarctic ice shelf to climate [PDF]

, 2016
The Antarctic Ice Sheet is buttressed by floating ice shelves. Calving at ice shelf front and basal melting below ice shelf are main ablation processes of Antarctic ice sheet(Rignot et al., 2013).

Water‐Stable Paper‐Based Laser‐Induced Graphene With Asymmetric Water Adhesion and Wettability

Advanced Materials Interfaces, EarlyView.
Paper‐based electronics are attractive for sustainable and disposable devices, but often fail in wet environments. By introducing Parafilm into cellulose paper combined with laser conversion, two graphene surfaces with different water interactions are created.

Anti‐Slip Material‐Based Strategies and Approaches

Advanced Materials Technologies, EarlyView.
This review highlights the principle mechanisms of slipping at the microscale, linking contact mechanics with a friction behavior model for surface interfaces. Main strategies to develop anti‐slip properties to the surfaces are discussed alongside standardized testing approaches.
