Chlorination‐Enabled Oxygen Control and Dual‐Sulfur Source Aided Trap Passivation to Unlock 8.24% Efficient Sb2S3 Photovoltaic Devices

open access: yesAdvanced Functional Materials, EarlyView.
This work demonstrates a scalable, low‐temperature synthesis strategy that combines a thioacetamide (TA)‐based dual sulfur source with CdS chlorination, enabling the formation of high‐quality Sb2S3 with a reduced open‐circuit voltage loss, resulting in improved device efficiency.

Eye and Ultraviolet Light

open access: yes, 2005
peer reviewedAll the ocular structures, from cornea to retinal layer, can be damaged by exposure to the light radiations. Acute keratitis combined with conjunctivitis will result from an intensive photic exposure. On the other hand, pterygion more likely

Influence of Ultraviolet Paint and Lamp on Swimming Characteristic of Fish

open access: yes, 2013
Fish can see not only the visible rays of light for human being but also the ultraviolet rays. However, the effects of the ultraviolet rays on the fish behavior have not been investigated. It is known that the reaction of fish against the reflected light

Measurement of solar ultraviolet radiation intensity type A and B in Qazvin (2013-14)

open access: yesThe Journal of Qazvin University of Medical Sciences, 2016
Background: Solar ultraviolet radiation (UVR) is considered one of the most important biological risk factors in the world. Most health damages from solar ultraviolet radiation at ground level are mainly caused by UVA and UVB spectrums.

Swelling‐Induced Stress‐Assisted Transfer of Nanodiamond Arrays With a PVA Carrier Tape for Conformal Bio‐Integrated Sensing and Labelling

open access: yesAdvanced Functional Materials, EarlyView.
This work introduces a swelling‐induced, stress‐assisted water‐soluble PVA tape strategy to transfer‐print nanodiamond quantum‐sensor arrays onto soft, curved biological interfaces. The room‐temperature, water‐triggered process achieves >98% fidelity and residue‐free integration, enabling conformal quantum sensing on contact lenses, neural probes, and ...

Physics from Time Variability of the VHE Blazar PKS 2155-304 [PDF]

open access: yes, 2010
Blazars are the principal extragalactic sources of very high energy gamma-ray emission in the Universe. These objects constitute a sub-class of Active Galactic Nuclei whose emission is dominated by Doppler boosted non-thermal radiation from plasma ...

Effectiveness of Gamma Ray and U.V Light on the Penecillin Resistant Strains of Staphylococcus aureus

open access: yesپزشکی بالینی ابن سینا, 2005
Nowadays, the multiple drug resistance and resistance to different antimicrobial are observed in a wide variety of bacteria. One of these agents is U.V. ray that sometimes used to sterilize the operation room space and utensils and gamma ray to sterilize

Polarity‐Reversible Photoresponse–Driven Autonomous Wavelength Discrimination in Quantum Dot–Tellurium Thin‐Film Photodetectors via Engineered Energy‐Band Alignment

open access: yesAdvanced Functional Materials, EarlyView.
A quantum dot–tellurium thin‐film photodetector autonomously discriminates visible and infrared wavelengths through polarity‐reversible photoresponses. Engineered carrier separation and gain modulation enable filter‐free multispectral sensing within a single‐device architecture.

Computer modeling and experimental work on the astrobiological implications of the martian subsurface ionising radiation environment [PDF]

open access: yes, 2008
Any microbial life extant in the top meters of the martian subsurface is likely to be held dormant for long periods of time by the current permafrost conditions.
