German Antarctic activities

open access: yesAntarctic Record, 1997
The methods of Antarctic expeditions are different from country to country in terms of scale of the expedition, organization, funding, geographical situation of the area of activity and so on. Although methods used by one country are not always adaptable

Click Capture SELEX for the Identification of Click‐Modified Aptamers Targeting Small Molecules in Solution

open access: yesChemistry – A European Journal, EarlyView.
Using kanamycin A as a model target, we developed click‐capture SELEX to identify nucleobase‐modified aptamers capable of binding small molecules in solution. This approach enables flexible incorporation of nucleobase modifications via CuAAC, allowing the chemical properties of the aptamer to be tailored to the target molecule.

Synergistic Modulation of Conductivity and Oxidation Stability in SiHfBCN Ceramics via UV‐Assisted Structural Evolution

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A quinary UV‐curable SiHfBCN ceramic photoresist with high ceramic yield enhanced is developed through sequential molecular design for high‐temperature sensing coatings. The elevated interconnected conductive network induced by chemically bonded carboxylated MWCNTs enables the pyrolyzed ceramics' enhanced conductivity and excellent oxidation stability.

Design and Experimental Study of Pressure Maintenance and Temperature Control System for Hydrate Pressure Core Processing Device

open access: yesEnergy Science &Engineering, EarlyView.
This paper presents a hydrate pressure core processing device integrated with a high‐precision active control system to perform nondestructive transfer, cutting, and analysis. To address the limitations of slow dynamic response and high thermal inertia in traditional passive systems, a differentiated control scheme is implemented.
