Enhancing Optoelectronic Properties in Phthalocyanine‐Based SURMOFs: Synthesis of ABAB Linkers by Avoiding Statistical Condensation with Tailored Building Blocks

Advanced Functional Materials, EarlyView.
A novel phthalocyanine (PC)‐based metal–organic framework (MOFs) is synthesized using ditopic PC linkers obtained through regioselective statistical condensation. The resulting MOF exhibits significant improvements in electronic absorption, thereby enhancing the material's performance in light harvesting and energy conversion.

Detection of prospective areas for mineralization deposits using image analysis technique of aeromagnetic data around Marsa Alam-Idfu road, Eastern Desert, Egypt

Egyptian Journal of Petroleum, 2019
Area around Marsa Alam-Idfu road is considered as one of the most prospective regions for gold and base metals mineralization in Egypt. The total intensity aeromagnetic reduced to northern magnetic pole (RTP) data of such area revealed that a set of ...

Preparation, dielectric and conductivity studies of LiNi1-xMgxO2 cathode materials for lithium-ion batteries [PDF]

Processing and Application of Ceramics, 2017
A layered structure cathode materials LiNi1-xMgxO2 (where x = 0.0 and 0.02) were prepared by solid state reaction from Li2CO3, MgO and NiO. The thermal analysis of the precursor materials up to 750 °C showed the weight loss of about 30%.

Who Are the Young Adults in Portugal? Daily Usage of Social Media and Mobile Phones, in a No-Kids and No-Independent Housing Context—Results from a Representative Online Survey

Youth, 2023
Better theories and practices are constructed through a deep understanding of the subjects involved. In Portugal, young adults aged 18 to 30 are a group sometimes left out because the Portuguese official statistical data does not treat this as an age ...

Systematization of tensor mesons and the determination of the $2^{++}$ glueball [PDF]

, 2004
It is shown that new data on the $(J^{PC}=2^{++})$-resonances in the mass range $M\sim1700-2400 $MeV support the linearity of the $(n,M^2)$-trajectories, where $n$ is the radial quantum number of quark--antiquark state.

Quantifying Aspect Bias in Ordinal Ratings using a Bayesian Approach [PDF]

, 2017
User opinions expressed in the form of ratings can influence an individual's view of an item. However, the true quality of an item is often obfuscated by user biases, and it is not obvious from the observed ratings the importance different users place on

Terminations VI and VIII (∼ 530 and ∼ 720 kyr BP) tell us the importance of obliquity and precession in the triggering of deglaciations

, 2012
The main variations of ice volume of the last million years can be explained from orbital parameters by assuming climate oscillates between two states: glaciations and deglaciations (Parrenin and Paillard, 2003; Imbrie et al., 2011) (or terminations). An

Photoswitchable Conductive Metal–Organic Frameworks

Advanced Functional Materials, EarlyView.
A conductive material where the conductivity can be modulated remotely by irradiation with light is presented. It is based on films of conductive metal–organic framework type Cu3(HHTP)2 with embedded photochromic molecules such as azobenzene, diarylethene, spiropyran, and hexaarylbiimidazole in the pores.
