Investigation of stratiform sulphide mineralisation at Meall Mor, South Knapdale, Argyll [PDF]

, 1978
A co-ordinated geochemical-geophysical-geological investigation of copper mineralisation in the Meal1 ?46r area, South Knapdale, Argyll was carried 0th in 1976 and followed by a drilling programme of 3 shallow holes in early 1977.

Ab initio energies of nonconducting crystals by systematic fragmentation [PDF]

, 2015
A systematic method for approximating the ab initio electronic energy of molecules from the energies of molecular fragments has been adapted to estimate the total electronic energy of crystal lattices. The fragmentation method can be employed with any ab

Challenges of II‐VI and III‐V Blue Quantum Dot Light‐Emitting Diodes

Advanced Materials, Volume 38, Issue 2, 8 January 2026.
Blue‐emitting electroluminescent quantum dot light‐emitting diodes (QD‐LEDs) face critical challenges that limit their practical application, including short operational lifetimes, low color purity, broad spectral linewidths, and unpredictable transient effects like blinking and positive aging.

Particle Shape-Based Evaluation of the Leaching of Sphalerite Ore in Dilute Acid Solutions

Journal of Advanced Research in Natural and Applied Sciences
In this study, the effects of changes in particle shapes on dissolution efficiencies in zinc (Zn) recovery from a lead-zinc (Pb-Zn) ore by acid leaching method were investigated.

On the sphalerite geobarometer.

GEOCHEMICAL JOURNAL, 1988
Even though the sphalerite geobarometer enjoys wide support as a very reliable parameter which gives pressure values consistent with the pressures obtained by different silicates equilibrium, thermodynamically the internal consistency of its experimental data may be questioned. The pressure read from the geobarometer should be regarded tentatively.

Self‐Catalyzed AlGaAs Nanowires and AlGaAs/GaAs Axial Heterostructures Grown by Molecular Beam Epitaxy

Advanced Materials Interfaces, Volume 13, Issue 1, 7 January 2026.
Following the parameter modulation described in the manuscript, a high yield of branch‐free self‐catalyzed AlGaAs nanowires at various nominal Al contents with high material quality has been acquired. These branchless structures are ideal hosts for narrower bandgap GaAs quantum dots, promising for non‐classical light‐emitting applications.

Oxygen application to chloride leaching of complex sulfide ores [PDF]

, 1987
The study investigates leaching of complex sulfide ores with simultaneous regeneration of the leaching solution and removal of dissolved iron to balance the iron concentration in the leaching process.

Defect‐Cascades‐Induced Photodegradation in InP/ZnSe/ZnS Quantum Dots

Advanced Science, Volume 13, Issue 4, 19 January 2026.
Surface sulfur vacancies in InP/ZnSe/ZnS quantum dots trigger vacancy cascades under blue light, propagating toward the ZnSe interface. In situ ESR (g = 2.004, 2.012) and DFT reveal a defect‐driven shift from type‐I to type‐II band alignment, reducing radiative recombination and EQE.

Stratabound arsenic and vein antimony mineralisation in Silurian greywackes at Glendinning, south Scotland [PDF]

, 1983
Stratiform and disseminated pyrite-arsenopyrite concentrations are overprinted by fracturecontrolled polymetallic mineralisation including stibnite through at least tens of metres of Silurian sediments at Glendinning, near Langholm.

Recent Progress in Mechanoluminescence for Multi‐Dimensional Stress Monitoring

Advanced Science, Volume 13, Issue 5, 27 January 2026.
Multi‐dimensional stress visualization technology (0D point detection, 1D linear distribution, 2D planar imaging, 3D volume reconstruction) has become a focus of attention in the field of stress sensing. The transition from “points” to “multi‐dimensional spatial fields” facilitates real‐time, in situ, and high‐resolution visualization of stress ...
