Controlled laser‐drilling of embedded HfO2 membranes creates three layer nanopores with Gaussian‐shaped cavities sculptured in the supporting layers. These embedded solid‐state nanopores slow DNA translocation by 12‐fold compared to SiNx pores, enabling high‐resolution, label‐free detection of short DNAs, RNAs, and proteins.

It is reported that the ferroelectric switching behavior of rhombohedral (3R) phase transition metal dichalcogenide (TMD) bilayers strongly depends on their domain structures. Single‐domain TMDs (SD‐TMDs) with domain‐wall‐free structures exhibit robust and stable polarization switching, whereas poly‐domain TMDs (PD‐TMDs) with randomly distributed ...

Single Solid‐State Ion Channels as Potentiometric Nanosensors
Single gold nanopores functionalized with mixed self‐assembled monolayers act as solid‐state ion channels for direct, selective potentiometric sensing of inorganic ions (Ag⁺). The design overcomes key miniaturization barriers of conventional ion‐selective electrodes by combining low resistivity with suppressed loss of active components, enabling robust

Experimental Investigations on Penetration Rate of Percussive Drill
AbstractIn this paper, detailed studies were carried out to determine the influence of rock properties on the penetration rate during pneumatic drilling. Further investigation was also carried out on the effect of thrust, air pressure, and compressive strength on penetration rate.

Recovery at Morvin: SERPENT final report [PDF]
Recovery from disturbance is poorly understood in deep water, but the extent of anthropogenic impacts is becoming increasingly well documented. We used Remotely Operated Vehicles (ROV) to visually assess the change in benthic habitat after exploratory ...

An impedance approach to reduce the contact-instability whilst drilling with active heave compensation [PDF]
The bit-bounce, or contact-instability, phenomenon which occurs in the drill string suspended from a floating vessel with an active drill string compensator to maintain a steady weight on the drill bit is investigated.

A van der Waals optoelectronic synaptic device based on a ReS2/WSe2 heterostructure and oxygen‐treated h‐BN is presented, which enables both positive and negative PSCs through photocarrier polarity reversal. Bidirectional plasticity arises from gate‐tunable band bending and charge trapping‐induced quasi‐doping.

Wellbore Circulating Temperature Field Model for Ultra-High Density Oil-Based Drilling Fluid
The existing bottomhole pressure models assume that the circulation temperature of drilling fluid is the formation temperature, which always leads to large errors in calculations.

Migration laws of natural gas hydrate solid particles with different abundance in horizontal wells
When a horizontal well is drilled through the natural gas hydrate (NGH) strata with different abundance, the NGH-bearing solid debris tends to lead to the deposit and adhesion of solid particles in the lateral sections and consequently cuttings carrying ...
