Real‐time lithology identification while drilling based on drill cuttings image analysis with ensemble learning

Deep Underground Science and Engineering, EarlyView.
A lithology identification while drilling method was developed, integrating an automated cuttings sampling system, a smart drilling rig, and an ensemble learning model. Underground trials achieved 97.42% accuracy in real‐time identification of cuttings lithology and composition, enhancing hazard management and supporting unmanned drilling technology in

Transient Charging Dynamics in Stacked Ga2O3/ZnO Photovoltaic Units Governing Wavelength‐Selective Polarity Switching

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work reveals a “Photovoltaic‐Capacitance” coupling mechanism in stacked Ga2O3/ZnO devices, defining the ZnO/graphene interface as a novel Photovoltaic Dynamic‐Capacitor (PDC). The wavelength‐selective bipolar response enables a physical layer secure communication protocol based on ternary optical logic (“1,” “0,” “−1”).

Evaluation of Drillability of the Mahu Conglomerate Formation in Xinjiang, China

Energy Science &Engineering, EarlyView.
This graphical abstract illustrates the workflow for developing an optimized prediction model using measurement while drilling (MWD) data. A total of 90 MWD cases are divided into a training set (80%) and a test set (20%). Four logging‐while‐drilling parameters—compensation density, acoustic travel time, resistivity, and neutron porosity—are selected ...

Uniform Microscale Thermoresponsive Liposomes for Controlled Release Above Body Temperature

Small, EarlyView.
Uniform thermoresponsive liposomes are generated using a scalable double‐emulsion microfluidic approach coupled with accelerated solvent extraction. The resulting liposomes remain stable at physiological temperature but undergo abrupt rupture and cargo release at 41°C–45°C, providing a versatile platform for thermally triggered controlled release in ...
