Thermophysical Properties of Lunar Regolith Revealed by Thermal-infrared Observations of the Lunar Reconnaissance Orbiter (LRO) Diviner Radiometer

open access: yesThe Astrophysical Journal
The thermophysical properties of lunar regolith are crucial for lunar sciences and engineering. Here, we evaluate the thermophysical properties of lunar regolith between 75°N and 75°S from Diviner data by treating the radius of lunar regolith grains as a

Youth living with HIV/AIDS in secondary schools: perspectives of peer educators and patron teachers in Western Uganda on stressors and supports

open access: yesSAHARA-J, 2019
As Youth Living With HIV/AIDS (YLWHA) continue to survive and live with HIV chronically due to effective Antiretroviral Therapy (ART), it is paramount to work toward maximising their psychosocial wellbeing.

PiP‐Plex: A Particle‐in‐Particle System for Multiplexed Quantification of Proteins Secreted by Single Cells

open access: yesAdvanced Materials, EarlyView.
Detecting proteins secreted by a single cell while retaining its viability remains challenging. A particles‐in‐particle (PiPs) system made by co‐encapsulating barcoded microparticles (BMPs) with a single cell inside an alginate hydrogel particle is introduced.

Practical suggestions on detecting exomoons in exoplanet transit light curves

open access: yes, 2010
The number of known transiting exoplanets is rapidly increasing, which has recently inspired significant interest as to whether they can host a detectable moon. Although there has been no such example where the presence of a satellite was proven, several

Chiral Acoustic Phonon and Conservation of Pseudoangular Momentum in α‐Quartz

open access: yesAdvanced Materials, EarlyView.
Chiral acoustic phonons in α‐quartz are probed via Brillouin light scattering, exploiting the photon's helicity and the crystal's handedness. The interaction obeys a selection rule arising from pseudoangular momentum conservation, enabling direct optical access to phonon chirality in nonsymmorphic crystals.

Mesenchymal Stem Cell‐Inspired Microneedle Platform for NIR‐responsive Immunomodulation and Accelerated Chronic Wound Healing

open access: yesAdvanced Materials, EarlyView.
The research demonstrates a Mesenchymal Stem Cell‐inspired microneedle platform (MSCi@MN) that addresses chronic diabetic wounds by combining MSC‐derived extracellular nanovesicles (NV)–DNA conjugates in microneedle tips with photothermal MXene in the patch layer.

Volatile loss following cooling and accretion of the Moon revealed by chromium isotopes [PDF]

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2018
Significance With the exception of volatile elements, which are strongly depleted and isotopically fractionated, the Moon has chemical and isotopic signatures that are indistinguishable from Earth’s mantle.

Silver Ions as Ambipolar Dopants in InAs Nanocrystal Solids

open access: yesAdvanced Materials, EarlyView.
Ag⁺ ions post‐introduced into InAs nanocrystal films act as ambipolar dopants whose effect depends on host polarity and dopant concentration. In n‐type InAs nanocrystal films, Ag⁺ occupies interstitial sites to yield n‐type doping effect, whereas in Zn‐doped p‐type InAs nanocrystal films, it first forms p‐type surface doping effect and later induces n ...

The Equivalence Principle and the Moon

open access: yes, 1995
The perturbation of the lunar motion caused by a hypothetical violation of the equivalence principle is analytically worked out in terms of power series \`a la Hill-Brown.
